Camless engines eliminate mechanical linkages between the crankshaft and valves, allowing for infinite variability of valve timing, lift, and duration. Sensors monitor engine parameters and send signals to an ECU, which controls actuators to vary the valves as needed. This electrohydraulic camless system uses compressed hydraulic fluid and a hydraulic pendulum mechanism to accelerate and decelerate the valves independently according to requirements. Camless engines provide benefits like improved fuel efficiency, higher power and torque, and reduced size and weight compared to conventional camshaft engines. However, they also have disadvantages including added complexity and costs. Overall, camless valve technologies are expected to replace conventional camshaft designs in the future.

The document discusses a sliding mesh gear box. It describes the gear box as a collection of mechanical components that deliver power from an engine through a series of gear ratios to operate a transmission. It then explains that a gear box provides variable torque ratios for acceleration and climbing gradients and allows for reversing vehicle motion. It notes that sliding mesh gear boxes typically have 3 forward gears and 1 reverse gear, using spur gears that slide to engage gears on the main shaft with those on the lay shaft/counter shaft. The document concludes by outlining the power flow path through gear engagement in low, medium, and high gears and how the reverse gear operates through an idler gear.
The document discusses three types of mechanical energy storage: pumped hydroelectric storage (PHS), compressed air energy storage (CAES), and flywheels. PHS involves pumping water to a higher elevation and releasing it through turbines to generate power. CAES compresses air underground for later use in power generation. Flywheels store energy kinetically in a spinning rotor. Each technology has benefits like cost-effectiveness (PHS) or ability to help integrate renewable energy, but also challenges such as energy losses or limited locations. Flywheels in particular can have very high cycle life compared to batteries.

Turbocharger and Supercharger (Anil Sharma)ANIL SHARMA
Superchargers and turbochargers both work to increase the density of the air-fuel mixture inducted into an engine, allowing for more power output. A supercharger is mechanically driven by the engine's crankshaft, while a turbocharger uses the engine's exhaust gases to drive a turbine which spins a compressor. Superchargers provide immediate power but are less efficient, while turbochargers have lag but allow for smaller engine sizes. Both systems provide more horsepower but also have disadvantages like increased cost, complexity, and maintenance requirements.

This document discusses supercharging and turbocharging of internal combustion engines. It begins by explaining that supercharging and turbocharging aim to increase engine power output by supplying air or air-fuel mixture at a pressure higher than ambient pressure, thus increasing density and mass of the intake charge. It then describes the three main types of superchargers - centrifugal, roots, and vane types - and compares their characteristics. Turbocharging is introduced as using a gas turbine powered by exhaust gases to drive the supercharger, avoiding the need for a mechanical linkage. The principles of exhaust gas turbocharging for a single-cylinder engine are illustrated. Effects of supercharging such as increased power output and torque are also outlined.
This document presents a project presentation by six students at Seacom Engineering College on the study and demonstration of the principles of a turbocharger. It includes definitions of a turbocharger and supercharger, explanations of why turbochargers are used instead of superchargers, diagrams of key turbocharger components like the turbine, compressor, shaft, and housing. It also covers the Brayton cycle that turbochargers are based on and comparisons of naturally aspirated versus supercharged engine P-V diagrams. Application areas and improvements in turbocharger performance over time are summarized as well.
A turbocharger works by using the waste exhaust gases from the engine to power a turbine wheel, which is connected by a common shaft to a compressor wheel. As the turbine wheel spins faster, it spins the compressor wheel faster, increasing the amount of air the compressor can draw into the engine. This compressed air allows the engine to burn more fuel, increasing power. The turbocharger is lubricated by engine oil which cools and lubricates the bearings and seals that allow the turbine and compressor wheels to spin at high speeds.
Performance analysis of ic engine using supercharger and turbocharger a revieweSAT Journals
Abstract
There are many inventions aimed at increasing the performance of IC engines. So most engines nowdays are employed with
turbocharger and supercharger. It is known that the power outputs of an engine increases with the increase in amount of air or
mixture in the cylinder and supercharger plays an important role in increasing the amount or air. Turbochargers are used
throughout the automotive industry as they can enhance the output of an internal combustion (IC) engine without the need to
increase its cylinder capacity. The emphasis today is to provide a feasible engineering solution to manufacturing economics and
“Greener” road vehicles. It is because of these reasons that superchargers and turbochargers are now becoming more and more
popular in automobile applications. The aim of this paper is to provide a review on the techniques used in supercharging and
turbocharging to increase the engine output and reduce the exhaust emission levels.
Keywords: IC Engine, Supercharger, Turbocharger.
This document discusses different forced induction systems for internal combustion engines. It defines a supercharger as a mechanically-driven air compressor, while a turbocharger uses a turbine powered by exhaust gases to drive its compressor. A turbosupercharger combines both systems to maximize power output. Superchargers and turbochargers increase air intake and thus support higher combustion rates. While turbochargers are more efficient due to utilizing otherwise wasted exhaust energy, superchargers do not subtract engine power. Forced induction allows downsized engines to perform on par with larger naturally aspirated engines.
This document provides an overview of turbochargers, including:
- A turbocharger uses exhaust gases to drive a turbine which spins a compressor to force more air into the engine, increasing power.
- Early applications included aircraft in the 1930s and production cars in the 1960s.
- Key components are the turbine, compressor, center housing, and wastegate to control pressure. Proper installation is also discussed.
The document discusses turbochargers, including their advantages over other charging methods like superchargers. It describes how turbochargers can increase engine power and efficiency while reducing engine size. It also covers various turbocharger components like turbines, bearings and vibration, as well as operating issues like fouling, surging and fires in the scavenge system.
A turbocharger uses a turbine powered by exhaust gases to force more air into the engine, increasing power output. It differs from a supercharger which uses a mechanically-driven compressor. Early turbochargers were sometimes called "turbo superchargers" causing confusion. Turbochargers require lubrication of bearings supporting the rotor assembly. Variable geometry turbochargers (VGTs) like those in Tata vehicles optimize performance at all engine speeds by adjusting the geometry controlled by the ECU.

The document provides information about superchargers and turbochargers, including:
- Superchargers are driven mechanically by the engine and provide instant boost but use some engine power, while turbochargers harness wasted exhaust energy and do not drain engine power.
- Boost control systems like bypass valves and wastegates are used to regulate boost pressure and prevent overboosting the engine.
- Intercoolers help increase power potential by cooling compressed intake air.
- Turbo lag refers to the delay between engine acceleration and boost from the turbocharger due to inertia in the exhaust and intake systems. Larger turbochargers have more lag.
- Turbochargers use the otherwise wasted exhaust energy from engines to drive a turbine connected to an air compressor, boosting intake air pressure and engine power output.
- By pressurizing intake air, more fuel can be burned, improving engine efficiency and allowing engines to maintain higher power levels even at high altitudes where air is thinner.
- While turbochargers improve power, they require careful maintenance due to high exhaust temperatures and added complexity, which can increase failure risks if not properly serviced. For agricultural tractors, turbocharging is an effective way to boost low-speed power generation and high-altitude operation.

IRJET- Experimentation of Performance and Emission Test in Single Cylinder SI...IRJET Journal
This document discusses an experiment conducted on a single cylinder spark ignition engine to test the performance and emissions with the addition of a turbocharger and exhaust gas recirculation (EGR). The experiment aims to improve engine efficiency while reducing emissions like CO2 and noise. A turbocharger compresses intake air using the energy in exhaust gases to drive a turbine. EGR recirculates a portion of exhaust gases back into the intake to reduce emissions. The experiment was conducted on a TVS Star City bike powered by a 109.7cc air-cooled engine. A turbocharger and EGR system were added to the stock engine configuration. The results were meant to analyze changes in performance and emissions with these modifications.
This document provides a review of turbocharging techniques for internal combustion engines. It begins by explaining how a turbocharger works by using the engine's exhaust gases to spin a turbine, which then spins an air pump to force more air into the engine cylinders. This allows more fuel to be burned, increasing power output. The document then reviews several past studies on technologies used to improve turbocharging efficiency, such as variable geometry turbochargers, hybrid turbocharging using an assist motor, and analyzing engine availability during transient operation. The goal of these technologies is to better match the turbocharger to the engine to enhance performance and reduce emissions throughout the operating range.
Structure Analysis of a Turbocharger Compressor Wheel Using FEAIJERA Editor
When people talk about race cars or high-performance sports cars, the topic of turbochargers usually comes up. Turbochargers also appear on large diesel engines. A turbo can significantly boost an engine's horsepower without significantly increasing its weight, which is the huge benefit that makes turbos so popular. Turbochargers are a type of forced induction system. They compress the air flowing into the engine. The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder. Here in this project we are designing the compressor wheel by using Pro-E and doing analysis by using FEA package. The main aim of the project is to increase the performance of the compressor wheel for this we are changing the material and also we are changing the existing design. By comparing the results we will get the best model from this data we suggests the design modifications to the company to improve the performance of the compressor wheel.

The Research Designs and Standards Organisation (RDSO) was established in 1952 as the Railway Testing and Research Centre to investigate railway problems and provide design criteria and concepts in India. It was renamed RDSO in 1957. A turbocharger uses a turbine powered by exhaust gases to drive a compressor that increases the pressure and density of air supplied to an internal combustion engine, allowing it to burn more fuel and produce more power. Turbochargers force more air into the engine cylinders than normally aspirated engines through a compressor powered by a turbine on a shared shaft. They provide more efficient air-fuel mixing and allow locomotives to gain power without increasing engine size, but have disadvantages like turbo lag and increased complexity.
DTS-I and DTSS-I are technologies that use twin spark plugs located on either side of the combustion chamber of an engine. This allows for greater combustion rates and more efficient burning of fuel compared to a traditional single spark plug engine. The twin spark plugs are controlled by a microprocessor that can optimize ignition timing for better performance. These dual spark technologies provide benefits like reduced emissions and fuel consumption while increasing an engine's power and lifespan.
Turbochargers and superchargers compress air entering an internal combustion engine to increase power output. Turbochargers use exhaust gases to drive a turbine which spins a compressor, while superchargers use a belt connected to the engine crankshaft. Early applications included large ships and trucks in the 1930s. Turbocharged passenger cars debuted in the 1960s but had reliability issues. Stricter emissions regulations in the 1980s increased turbocharging of diesel truck engines. Today various turbocharger designs are used to optimize performance across the engine's rev range.
The document describes a compressed air vehicle that uses compressed air stored in onboard tanks to power an engine and drive the vehicle. Key points:
1) Compressed air vehicles store pressurized air in onboard tanks at around 30 bar and use the expansion of this air to drive pistons in an engine, converting the air power into mechanical power to run the vehicle.
2) The vehicle described uses a modified Hero Honda CD100 engine connected to wheels through a transmission. It stores around 0.05 cubic meters of compressed air in a mild steel or potential carbon fiber tank.
3) Compressed air vehicles have the advantages of being emissions-free since they only expel compressed air, not requiring cooling systems
This document proposes fabricating an exhaust duct for cylinder nine of an engine to protect the turbocharger. The original straight duct allows debris from the engine to damage the turbocharger rotor. The proposed duct design includes an inclined section with a collection trap to catch debris before it reaches the turbocharger. It can be fabricated locally for 800 KSH or outsourced for 1.8 million KSH. The duct aims to prevent the 35 million KSH cost of replacing a damaged turbocharger rotor.
Turbochargers increase an engine's efficiency and power output by forcing extra compressed air into the combustion chamber. They have been used since the early 1900s but became more common in automobiles following the 1973 oil crisis. A turbocharger consists of a compressor and turbine connected by a shaft, with the turbine powered by exhaust gases that spin the compressor and force more air into the engine cylinders. Proper maintenance like regular oil changes is important to prevent failures and extend the life of turbocharger components exposed to high temperatures and pressures.

The document discusses Digital Twin Spark Ignition (DTS-I) technology used in some 4-stroke petrol engines. DTS-I uses two spark plugs placed at opposite ends of the combustion chamber to more completely burn the air-fuel mixture. This leads to increased power, reduced emissions, and better starting compared to a conventional single spark plug engine. Some motorcycles that use DTS-I technology include models from Bajaj like the Pulsar 135, 150, 180, and 200.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

INTRODUCTION
The output of the engine exhaust gas is given to the input of the turbine blades,
so that the pressurized air produced. This power, the alternate power must be
much more convenient in availability and usage. The next important reason for
the search of effective, unadulterated power are to save the surrounding
environments including men, machine and material of both the existing and
the next fourth generation from pollution, the cause for many harmful
happenings and to reach the saturation point. The most talented power against
the natural resource is supposed to be the electric and solar energies that best
suit the automobiles. The unadulterated zero emission electrical and solar
power, is the only easily attainable alternate source. Hence we decided to
incorporate the solar power in the field of automobile, the concept of many
Multi-nationals Companies (MNC) and to get relieved from the incorrigible air
pollution. What the turbo-charger was does is that it simply increases the
volumetric efficiency of the engine. The performance of an internal
combustion engine can be increased by adding turbocharging. A turbocharger
compresses the air so that more oxygen flows into the combustion chamber. In
this way, more fuel is burned and the power output of the engine increases
accordingly. The turbocharger is driven by exhaust gas, which makes
turbocharged diesel engines very efficient. MTU develops this key technology
for high-performance engines in-house. Turbocharger development and
production at MTU Turbocharging is an integral component of the engine
design concept. It shapes the characteristics of the engine more than almost
any other system, as it affects its economy, dynamics and emission
characteristics. This is why turbocharging is one of MTU’s key technologies.
MTU has a tradition of maintaining the expertise for developing and producing
its turbochargers in-house. The range of MTU turbochargers extends across
engine power ratings from 400 to 10,000 kW. Turbochargers are purchased for
engine designs in which synergy effects with the commercial vehicles sector
can be used.

In turbocharging, the turbocharger is being driven by a gas turbine using the
energy in exhaust gases. The major parts of turbocharger are turbine wheel,
turbine housing, turbo shaft, comp. wheel, comp. housing & bearing housing.
A 4-stroke S.I. Engine is an engine that uses gasoline as fuel. S.I.engine is a
spark ignited engine that is the combustion is carried out by spark ignition, it is
achieved by installation of spark plug on cylinder head.
In this project we are using Honda Stunner CBF 125cc for the installation of
turbocharger. The CBF125 is a motorcycle manufactured by Honda's Indian
subsidiary HMSI. The motorcycle is known as Stunner in the Indian market. In
India, it has two variants, the carburetor version simply called Stunner.
Turbo-Charger
Turbo-charging, simply, is a method of increasing the output of the engine
without increasing its size. The basic principle was simple and was already
being used in big diesel engines. European car makers installed small turbines
5. 3
turned by the exhaust gases of the same engine. This turbine compressed the
air that went on to the combustion chamber, thus ensuring a bigger explosion
and an incremental boost in power. The fuel-injection system, on its part, made
sure that only a definite quantity of fuel went into the combustion chamber.
BMW was the first to use turbo-charging in a production passenger car when
they launched the 2002 in 1973. The car was brilliantly packaged too and
paved the way for a simply magnificent ‘Turbo Era’ in the automotive world.
Swedish giant Saab took its cue from this and its ensuing 900 series was one of
the most characteristic turbo cars of its time. Intercoolers the latest turbo’s they
are used by most of today’s turbo-diesel engines to make the compressed air
denser. It works like this – on starting, exhaust gases spin the turbine and thus
activate a compressor that pressurizes the air. This pressurized air from the
turbo-charger is then sent through a duct to an air-cooled intercooler, which
lowers the temperature of the intake charge and thus increases its density. The
air-cooled intercoolers receive air through separate intakes and that explains
the small scoops and louvers usually found on the hoods of turbo-charged cars.
Modern turbo-diesel engines also make use of a temperature-sensitive, motor-
driven fan which boosts airflow at low engine speeds or when the intake air
temperature is high. Computers soon started playing an even bigger role in
cars. Engine management systems linked to fuel-injection systems meant
getting more out of the engine was even easier. For example, one can buy
chips that can boost power by 100 bhp for some Japanese cars, such as the
Nissan Skyline. Moreover, on-road speeds were being restricted all over the
world. Though most of the sports cars today are capable of doing more, they
are restricted electronically not to exceed 250 kmph even in autobahn-blessed
Germany. Turbo-charging lost its edge towards the end of the 1980s and today
this technology is used only in select performance cars. Porsche, for example,
is all set to build a turbo-charged version of its all-new 911 (water-cooled)
with added performance. Turbo engines were banned in Formula One too with
the idea of restricting the performance of the cars (and thereby making them
safer too). There are many who consider this a backward step in the world of
Formula One, which is considered to represent the ‘tomorrow’ of automotive
technology. But if one analyses the performance of normally aspirated cars in
F1 today (3,500 cc non-turbo), they perform as well, if not better, than the
6. 4
turbo cars of the early 1980s. So, there are no full stops in technology. While
road cars and even sports and racing cars are going in for more efficient
engines, better metallurgy and wilder-than-ever electronics to get their engines
to perform at an optimum level without sacrificing the performance edge,
turbochargers still continue to serve the same purpose they were invented for
albeit more so with diesel engines. Modern turbocharger is based on the
principle that if air entering in an engine is pressurized more oxygen and then
adding more fuel in the engine result in high torque and more power. A
turbocharged engine produces more power overall than the same engine
without the charging. This can significantly improve the power to weight ratio
for the engine. Now a day’s turbochargers are used in heavy vehicle, racing
cars and racing bikes. The Supercharger – or, as the Germans call it,
Kompressor! It’s a common tendency, especially amongst enthusiasts, to look
for ways in which to quench the thirst to produce ever more power from the
engine of their cars. Well, maybe not so much in our country—but certainly in
more affluent countries, where enthusiasts have the financial capability, and
desire, to soup up their cars in the search for better performance. One of the
most common solutions is to turbocharge a car—a technology we’ve looked at
in detail in the past—while the other popular route is to install a supercharger.
Now, these were actually invented even before the internal combustion engine
was developed for mainstream use in industrial and automotive applications.
So, as a technology, it’s been around for a while—and has seen constant
development over the years. Some of the earliest performance cars of the
world used superchargers to boost their performance—these included
legendary classics such as the Mercedes 540K, Bugatti Type 35C, and, of
course, the famous ‘Blower’ Bentley’s, which conquered Le Mans and were
the fastest cars of their day. So, it could be said that in the history of force
induction, this is the earliest, and one of the most successful progenitors. In the
1970s of past century, with the turbocharger’s entry into motor sports,
especially into Formula I racing, the turbocharged passenger car engine
became very popular. The word “turbo” became quite fashionable. At that
time, almost every automobile manufacturer offered at least one top model
equipped with a turbocharged petrol engine. However, this phenomenon
7. 5
disappeared after a few years because although the turbocharged petrol engine
was more powerful, it was not economical.
WORKING OF TURBOCHARGER
Since the power a piston engine can produce is directly dependent upon the
mass of air it can ingest, the purpose of forced induction (turbo-supercharging
and supercharging) is to increase the inlet manifold pressure and density so as
to make the cylinders ingest a greater mass of air during each intake stroke. A
supercharger is an air compressor driven directly by the engine crankshaft, and
as such, consumes some of the power produced by the combustion of fuel,
thereby increasing BSFC and engine wear for a given amount of produced
power. A turbocharger consists of a single-stage radial-flow (―centrifugal‖)
compressor (air pump), which is driven by a single-stage radial-flow turbine,
instead of being driven directly by the crankshaft. The turbine extracts wasted
kinetic and thermal energy from the high-temperature exhaust gas flow and
produces the power to drive the compressor, at the cost of a slight increase in
pumping losses.
HOW TURBOCHARGER WORKS
8. 6
INSTALLATION OF TURBOCHARGER
Steps for installation
1. Connect the turbo inlet with engine exhaust port with the help of studd nut &
welding.
2. The turbine shaft is connected to a compressor, which draws in combustion
air, compresses it, and then supplies it to the engine.
3. Now connect air filter with turbo compressor section.
4. Connect turbo air inlet with hos pipe with bike air cleaner.
5. Now connect carburettor with air cleaner & with engine.
6. Connect silencer with waste gate from where the waste gas will flow.
WORKING PRINCIPLE
A turbocharger consists of a turbine and a compressor on a shared shaft. The
turbine converts heat to rotational force, which is in turn used to drive the
compressor. The compressor draws in ambient air and pumps it in to the intake
manifold at increased pressure, resulting in a greater mass of air entering the
cylinders on each intake stroke. The output of the engine exhaust gas is given
to the input of the turbine blades, so that the pressurized air produced. This

power, the alternate power must be much more convenient in availability and
usage. The next important reason for the search of effective, unadulterated
power are to save the surrounding environments including men, machine and
material of both the existing and the next fourth generation from pollution, the
cause for many harmful happenings and to reach the saturation point. We have
designed and fabricated a prototype of the Turbocharger was implemented in
Two- wheeler, In which the efficiency of the Engine can be increased. Thus
we have developed a method to increase the efficiency of the engine and at the
same time to control the Emissions from the engine. The experimental setup of
block diagram shows the arrangement of turbocharger in two- wheeler. This
type of engine will be more efficient than existing engine
BENEFITS OF TURBOCHARGING
Increased engine power output (in the region of 50%increase).
Improved fuel consumption on (improved pressure balance across the engine.
Altitude compensation.
A very high percentage of two wheel gasoline vehicles (48%) were found not
complying with the prescribed National Emission Standards. The increase in
Carbon monoxide and Hydro carbon emissions by two wheel gasoline engine
sat accelerated engine speed was quite significant.
About90%ofscootersand85%ofmotorbikes were found emitting CO within the
prescribed national standard of 4.5%. About 33% of scooters and 83% of
motor bikes were found emitting Hydrocarbon within 2000ppm.
Duringhalfthrottlingabout90%ofscooters and 93%ofmotorbikes were found
emitting HC within the prescribed national standard of 2000PPM.
•During full throttling about 52% of scooter sand 47% of motorbikes were
found emitting HC not within the prescribed national standard of 2000PPM.
It was observed that the Carbon monoxide emissions from two wheel vehicles
increased from two to three times at the full acceleration engine conditions.
10. 8
It was observed that the Hydrocarbon emissions from two wheel vehicles
increased from two to four times at the full acceleration engine conditions.
By the use of turbo charging in two wheelers the power can be enhanced. A
properly tuned turbo engine can produce 20% + more power compared to
stock but expect an increase in fuel consumption.
More power compared to the same size naturally aspirated engine.
Better thermal efficiency over naturally aspirated engine and super charged
engine because the engine exhaust is being used to do the useful work which
otherwise would have been wasted.
Automotive oil condition monitoring is far from a mature technology. As this
technology progresses and becomes more popular in the auto motive industry,
there will be many generations of sensors developed to improve accuracy and
range of capability.
While some vehicles come standard with oil change technologies today, the
majority do not. The companies developing these sensor technologies must be
able to convince the automotive industry and the public of their general
reliability and value. If this is successful, we may see condition-based oil
changes become the latest trend in vehicle technology over the next few years.
CONCLUSION
We have designed and fabricated a prototype of the Turbocharger was
implemented in Two- wheeler, In which the efficiency of the Engine can be
increased .Thus we have developed a method to increase the efficiency of the
engine and at the same time to control the Emissions from the engine. The
experimental setup of block diagram shows the arrangement of turbocharger in
two- wheeler. This type of engine will be more efficient than existing engines.
This work is an attempt to reduce our dependency on foreign oil and reduce
11. 9
the tailpipe emission from automobiles and this was an attempt to design and
implement this new technology that will drive us into the future. Use of
production turbo charger will reduce smog- forming pollutants over the current
national average. The first hybrid on the market will cut emissions of global-
warming pollutants by a third to a half and later modes may cut emissions by
even more.
ADVANTAGES

sized engine. A century of development and refinement—for the last century
the SI engine has been developed and used widely in automobiles.
Continual development of this technology has produced an engine that easily

and reformulated gasoline, today’s engines are much more efficient and less
polluting than those built 20 years ago.

DISADVANTAGES
Bike cost will increase. Engine weight will increase. If there will be improper
maintenance then there will be problem in turbo such as turbo lag.
Supercharger
A supercharger is an air compressor that increases the pressure or density of
air supplied to an internal combustion engine. This gives each intake cycle of
the engine more oxygen, letting it burn more fuel and do more work, thus
increasing power.
Power for the supercharger can be provided mechanically by means of a belt,
gear, shaft, or chain connected to the engine's crankshaft. When power is
provided by a turbine powered by exhaust gas, a supercharger is known as a
turbosupercharger. – typically referred to simply as a turbocharger or just
turbo. Common usage restricts the term supercharger to mechanically driven
units.
Type of supercharge
1. Root
2. Screw
3. Centrifugal
Root: - The roots type supercharger is by far the
oldest, dating back to before the 20th century.
However, it has been continuously updated since it
was first invented and used, and has managed to
hold its own in modern times in several areas.
Originally, roots type superchargers push extra
oxygen into engines by using meshed-lobe rotors
with two lobes. These rotors rotate in opposite
directions, trapping air in pockets and forcing it
from the inlet to the compressor chamber, where it is
13. 11
compressed and moved into the engine. Modern designs use the same basic
principal, but usually use rotors with three or even four lobes, as well as other
upgrades that can improve efficiency in dramatic ways.
Screw: - The screw type supercharger works in a similar way to the roots type
supercharger. Screw type superchargers work by using two counter rotating
screws, rather than rotors. While this seems similar enough to a roots type
supercharger, it actually offers very different advantages and disadvantages.
Screw type superchargers are very good at moving air — they lose very little
of it due to their design. Additionally, they can compress air as they move it
using their screws. However, these advantages are not without cost. Screw
type superchargers are significantly less powerful before reaching high RPM
— and if used on an engine that never reaches high RPM, they will not ever
achieve their potential.
14. 12
Centrifugal: - Centrifugal superchargers are similar to many pumps or fans.
They pull air through an intake using an impeller, which collects air and forces
it out into a progressively smaller area, compressing it and leading to an
engine, where it is put to work.
Centrifugal superchargers use their special features to their advantage, but not
without drawbacks. In general, they are excellent at moving a large volume of
air. As a result of this, they are among the most efficient and effective
superchargers. Centrifugal superchargers have comparatively few moving
parts. As a result of this, they are quite reliable, requiring little maintenance.
They also generate much less heat than their more complicated equivalents.
Unfortunately, they put a limited amount of pressure on this air, unlike the
other kinds of superchargers. They also perform less effectively at lower RPM.
The Difference between a Turbocharger and a Supercharger
Both turbochargers and superchargers are designed to force air into the
combustion chambers of the engine, yet they use different mechanical
operations to accomplish the task. A supercharger uses a gear driven by
another engine component; commonly, the crankshaft is equipped with a gear
to drive a belt, which drives the supercharger’s gear. As the engine spins, the
15. 13
belt drives a turbine that acts as an air compressor to condense the ambient air
and force it into the engine’s air intake, where it is sucked into the cylinder by
the piston’s intake stroke. The air is compressed further during the piston’s
compression stroke. With a turbocharger, the centrifugal compressor turbine is
spun by exhaust gases escaping the engine after they have been forced out of
the cylinder by the combustion of the air/fuel mixture and the piston’s exhaust
stroke. Other than where they derive their propulsion from, the process of air
induction is essentially the same for both superchargers and turbochargers.
Comparing Performance between a Turbocharger and a
Supercharger
Generally, the conventional theory is that turbochargers operate in a more
efficient manner than superchargers, as they do not rob from the power an
engine produces by placing a drag on the mechanical parts that power the
supercharger. Therefore, turbochargers provide performance enhancements
without robbing from fuel economy. Superchargers make the engine work
harder, and therefore, they theoretically rob from fuel economy; this is not
something most performance drivers consider a big concern, however. The
supercharger is considered to provide better throttle response because the air is
constantly being pumped at a high volume. Turbochargers have a tendency to
lag, waiting for the exhaust gas pressure to build and raise the air intake RPM
of the turbine. With that being said, modern turbo design combined with
advanced engine electronics has leveled the playing field, and most
turbochargers on today’s performance vehicles do not suffer from turbo lag.

Twin-turbo
Twin-turbo or biturbo refers to a turbocharged engine in which two
turbochargers compress the intake charge. More specifically called "parallel
twin-turbos". Other kinds of turbocharging include sequential turbocharging,
and staged turbocharging. The latter is used in diesel automobile racing
applications.
TYPE OF TWIN TURBO CHARGER
1. Parallel twin turbo charger
2. Sequential Twin Turbochargers
Parallel Twin Turbochargers
With a parallel design, the two turbochargers each share half of the engine’s
exhaust gases. Commonly used in a V6 engine, one turbo feeds off the left
bank of cylinders, and the other feeds off the right bank. Think of it as running
two three-cylinder engines that are synced together. This type of design model
would not be possible without advanced engine electronics that can balance
the airflow of the twin turbos to achieve the synced intake of combustion
gasses. The functional advantage of parallel twin turbos is that with the
sophisticated engine electronics in today’s cars, the turbo can add performance
while adding to the engine’s fuel economy.
Sequential Twin Turbochargers
With sequential twin turbos, the smaller of the two operates at low speeds and
the larger turbo kicks in at high speeds. Sequential twin turbos are often called
“two-stage turbo” because the smaller turbo will actually continue to run and
feed the larger turbo when it activates; hence, the sequential two-stage
moniker. This engineering design is not without fault; it takes a somewhat
complicated series of tubes or pipes to plumb a sequential twin turbo. The
design works well with diesel engines, which is where this type of
turbocharger is commonly used. Sequential twin turbos do a good job of

reducing turbo lag, something that would be more noticeable in a diesel-
powered vehicle.
