The document discusses the concept and working of a six-stroke internal combustion engine. A six-stroke engine generates power twice per cycle by adding two additional strokes to the traditional four-stroke cycle. This results in higher efficiency and lower fuel consumption compared to four-stroke engines. The six-stroke cycle includes intake, compression, power, exhaust, and two additional strokes where heated air is used to generate a second power stroke. Major inventors who developed six-stroke engines include Malcolm Beare, Bruce Crower, and Velozeta. The advantages are increased efficiency and reduced emissions, but disadvantages include increased complexity and cost.
Now a day the most difficult challenges in engine technology is to increase its thermal efficiency, If the efficiency is higher, than there will less fuel consumption and lower atmospheric emissions per unit of work produced by the engine. In Six Stroke engine, the name indicates a cycle of six strokes in which two are useful power strokes. The engine which we get by adding two more stroke in existing four stroke engines generates more power with higher fuel efficiency. The exhausted heat generated form four stroke cycle is used in this engine to get an additional power and exhaust stroke of the piston in the same cylinder. In this engine, steam is produce from water with the help of heat generated from four-stroke cycle, which is later used as a working fluid for the additional power stroke. This steam will force the piston down. As well as extracting power, the additional stroke cools the engine by water which is used for steam generation and removes the need for a cooling system which is used in four stroke Otto cycle and makes the engine lighter and giving 40% increased efficiency over the normal Otto cycle.

One of the most difficult challenges in engine technology today is the urgent need to increase engine thermal efficiency. In the first approach, the engine captures the heat lost from the four-stroke Otto cycle or Diesel cycle and uses it to power an additional power and exhaust stroke of the piston in the same cylinder. The pistons in this type of six-stroke engine go up and down six times for each injection of fuel. Fresh water is injected into the cylinder after the exhaust stroke and is quickly turned to superheated steam, which causes the water to expand to 1400-1600 times its volume and forces the piston down for an additional stroke.
A cooling system also serves to maximize volumetric charge efficiency by reducing the temperature of the charge during intake. This design also claims to reduce fuel consumption by 35%-40%.

Modifications are made to the crankshaft, camshaft, and cam followers to accommodate the additional strokes.
This document provides an overview of six-stroke engine designs that aim to improve efficiency over traditional four-stroke engines. It describes the working principles of various six-stroke engine types, including single piston designs by Griffin, Bajulaz, Crower, and Velozeta as well as opposed piston designs like the Beare head engine. The document also discusses the modifications needed to convert a conventional engine to a six-stroke design and analyzes the advantages of six-stroke engines like reduced fuel consumption and emissions.
The document provides an overview of internal combustion engines, including their classification, operation, and differences between engine types. It discusses four-stroke petrol and diesel engines in detail, describing the four strokes of each cycle. The key differences between petrol and diesel engines are outlined. Two-stroke engines are also summarized and compared to four-stroke engines. Various engine efficiencies are defined.
An internal combustion engine uses combustion of fuel to drive pistons that convert the energy to mechanical energy. The first modern internal combustion engine was created by Nikolaus Otto in 1876. There are different types of internal combustion engines classified by fuel, strokes, ignition, cycle, number of cylinders, and cooling method. The key parts include the cylinder, piston, connecting rod, valves, crankshaft, and flywheel. A four-stroke engine intakes air/fuel, compresses it, combusts it to push the piston, and exhausts gases over two revolutions, while a two-stroke engine does this in one revolution.
An internal combustion engine uses combustion of fuel to drive pistons that convert the energy to mechanical energy. The first modern internal combustion engine was created by Nikolaus Otto in 1876. There are several types of internal combustion engines including four-stroke gasoline engines, two-stroke gasoline engines, diesel engines, and rotary engines. Engines can also be classified based on their fuel, number of strokes, ignition method, combustion cycle, number of cylinders, and cylinder arrangement. The key parts of an internal combustion engine include the cylinder, piston, connecting rod, valves, crankshaft, and flywheel.
Study and Analysis of Six Stroke EngineIJERA Editor
Six Stroke engine, the name itself indicates a cycle of six strokes out of which two are useful power strokes. According to its mechanical design, the six-stroke engine with external and internal combustion and double flow is similar to the actual internal reciprocating combustion engine. However, it differentiates itself entirely, due to its thermodynamic cycle and a modified cylinder head with two supplementary chambers: combustion and an air heating chamber, both independent from the cylinder. In this the cylinder and the combustion chamber are separated which gives more freedom for design analysis. In addition to the two valves in the four stroke engine two more valves are incorporated which are operated by a piston arrangement. The Six Stroke is thermodynamically more efficient because the change in volume of the power stroke is greater than the intake stroke and the compression stroke. The main advantages of six stroke engine includes reduction in fuel consumption by 40%, two power strokes in the six stroke cycle, dramatic reduction in pollution, adaptability to multi fuel operation. Six stroke engine’s adoption by the automobile industry would have a tremendous impact on the environment and world economy .
This document provides an overview of internal combustion engines. It discusses the classification of IC engines based on fuel used, thermodynamic cycle, number of strokes, ignition method, cooling method, speed, number of cylinders, and cylinder position. It describes the four-stroke cycles of Otto petrol and diesel engines. The key differences between petrol and diesel engines are outlined. The document also compares two-stroke and four-stroke engines, discussing their cycles, revolutions, power strokes, flywheels, ports/valves, lubrication, efficiencies, and applications. Indicated power, mechanical efficiency, thermal efficiency, and specific fuel consumption are defined.
The document discusses a six-stroke engine which aims to improve fuel efficiency and reduce emissions compared to traditional four-stroke engines. It works by adding two additional strokes: after the four-stroke cycle is completed, fresh air is drawn in and expelled to capture waste heat for a secondary power stroke. This provides two power strokes per cycle and can increase efficiency by 40% while reducing pollution by up to 65%. However, the engine is more complex with more components and lower power per cylinder compared to four-stroke designs. Widespread adoption in automobiles could significantly reduce fuel use and emissions globally if efficiency gains are realized.
The document discusses the six stroke engine, which differs from a four stroke engine by having two power strokes - one from fuel and one from steam or air. It provides examples of six stroke engine designs and discusses the working strokes. The six stroke engine has higher efficiency than a four stroke engine but also has higher costs due to its more complex design with additional components. While promising for reducing fuel consumption and emissions, commercializing the six stroke engine faces challenges of high initial costs.
The increasing demands for low emissions and low fuel consumption in m odern combustion engines requires improved methods for combustion process. The Beare Head is a new type of six-stroke engine head design known as the �Beare Head� after its designer,Malcolm Beare. T he Beare Head uses a piston and ports very much like a two stroke engine to replace the overhead valve system t hat is found in four stroke engines today. The four-stroke block,piston and crankshaft remain unaltered. This combinat ion of two stroke and four-stroke technology has given the technology its name the �six stroke engi ne�. Six Stroke engine,the name itself indicates a cycle of six strokes out of which two are useful power strokes. According to its mechanical design,the six-stroke engine with external and internal combustion and double fl ow is similar to the actual internal reciprocating combustion engine.
Two laboratory reports were summarized:
1. A report on studying a two-stroke spark ignition engine, discussing its working principle, cycle, design parameters, types, parts, and comparing it to a four-stroke engine. The two-stroke was found to have more power strokes but lower efficiency.
2. A report on studying a rotary Wankel engine, explaining its four-stroke cycle arranged around an oval, types, parts, and concluding it is widely used with advantages over piston engines.

Piston-engine power plants have been used since the early 18th century and include diesel, gas, and dual-fuel engines. They vary in size from less than 1 kW to 65 MW. Larger, slower engines are more efficient but high-speed engines are used for backup power. Combined heat and power systems can achieve over 75% overall efficiency. Diesel engines are commonly used for power generation due to their high efficiency but produce more emissions than gas engines.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Abstract: The modern four stroke internal combustion engine has been widely applied due to excellent power
to weight ratio and reliability.However, the major downside of the even most efficient modern 4 stroke engine is
the production of significant amounts of excess heat energy, dissipated though the cylinder walls of the engine
and expelled as waste energy during the exhaust stroke of the cycleA Six Stroke Engine is that in which the
power is obtained twice in a cycle of six strokes. This engine generates more power with higher fuel efficiency
than the existing engines. As a result a new engine concept is formed, which is a six stroke engine.In a typical
four stroke diesel engine, Piston moves up and down twice in the cylinder during one rotation of crank. The
power stroke is obtained once during the two cycles that generates the torque to move vehicle. In Six stroke
engine the power stroke is obtained two times out of six strokes. The automobile industry is now seeking for the
best six-stroke design which adds one more power stroke which results more efficiency and better utilization of
the fuel. In this paper the concept, features and the comparative discussion on six-stroke engine is done. Further
it’s advantages and disadvantages are discussed.
Keywords: stroke, internal combustion engine, diesel
I. Introduction
The 6 stroke internal combustion engine is advancement over the existing 4 stroke internal combustion
engine which employs the same principle as that of the 4 stroke internal combustion engine. The 5th stroke or
the second power stroke uses the heat evolved in the exhaust stroke (directly or indirectly) as heat required for
the sudden expansion of the secondary fuel (air or water) which pushes the piston downward for the 2nd power
stroke thereby rotating the crankshaft for another half cycle. As heat evolved in the 4th stroke is not wasted, the
requirement for a cooling system is eliminated. Here fuel is injected once in every 3 complete cycles of the
crankshaft which is any time better than a 4 stroke internal combustion engine where fuel is injected once in 2
complete cycles of the crankshaft.
The six-stroke engine is a radical hybridization of two and four stroke engine that the top portion of two stroke
engines and the bottom rather the middle section of a four stroke engine. In six-stroke cycle, two parallel
functions occur in two chambers which result in eight event cycle: four events internal combustion cycle and
four event external Combustion cycles. [2] The first cycle of four events is of external combustion.
Pure air intake in the cylinder.
Pure air compression in the heating chamber.
Keeping pure air pressure in closed chamber where a maximum heat exchange occurs with the combustion
chambers walls, without direct action on the crankshaft.
Expansion of the super-heated air in the cylinder, work.
During this four event's cycle, the pure air never comes in direct contact with the heating source.
The second cycle of four events is of internal combustion.
Re-compressions of pure heated air in the combustion chamber.
Fuel injection and combustion in closed combustion chamber, without direct action on the crankshaft.
Combustion gases expanding in the cylinder, work.
Combustion gases exhaust.
During these four events, the air comes in direct contact with the heating source
Principle Of Six-Stroke Engine
The six-stroke engine describes a number of approaches in IC engine to utilize the waste heat from the
4-stroke diesel cycle or Otto cycle and use it to generate more power. Generally the one compression and one
power strokes are added to cycle which higher the thermal efficiency and reduces the fuel consumption. The
piston in six-stroke engine moves up and down six times for each injection of fuel. The first four strokes are
same as that of the 4-stroke engine after the exhaust the fuel-air mixture is again compressed and burned gases
are removed during the sixth stroke. The glowing combustion chamber allows the optimal burning of any fuel
and calcinate the residues. The first stroke of the six-stroke cycle, i.e. the admission of the air or of the air-fuel
mixture, involves only low pressure admission cylinders. The third and fourth strokes of this same cycle, i.e. the

second compression and the first expansion of the combustion gases respectively, involve only high pressure
combustion cylinders. The final discharge of the combustion gases under low pressure, which represents the
sixth stroke of the cycle, involves only low pressure admission cylinders and low pressure discharge cylinders
The engine shows 30-40 percent reduction in fuel consumption and also economical. The engine can also use
variety of fuel. As the engine has two powers stroke that gives the efficient burning of the fuel and lower the
pollution.
Analysis Of Six-Stroke Engine
The six-stroke engine consists of six stroke and these are shown in figure the each figure shows the movement
of the air-fuel mixture, valves and piston. The name of the components are-
1. Intake valve
2. Heating chamber valve
3. Combustion chamber valve
4. Exhaust valve
5. Cylinder
6. Combustion chamber
7. Air heating chamber
8. Wall of combustion chamber
9. Fuel injector
10. Heater plug
The working of all strokes in this engine is as below:
FIRST STROKE (suction stroke):During the first stroke, the inlet valve opens and air-fuel mixture from
carburettor is sucked into the cylinder through the inlet manifold.
SECOND STROKE(Compression Stroke): During the second stroke, piston moves from Bottom Dead Centre
to Top Dead Center, both the inlet valve and exhaust valves are closed and air-fuel mixture is compressed.

THIRD STROKE (Fuel Power Stroke): During the third stroke, power is obtained from the engine by igniting
the air-fuelmixture using a spark plug. Both valves remain closed. Piston moves from Top Dead Center to
Bottom Dead Center.
FOURTH STROKE (Re-Compression Stroke): During the third stroke, piston moves from Bottom Dead
Center to Top Dead Center. Both the inlet and the exhaust valves are closed. By the time piston reaches Top
Dead Center, water injector injects water which is then converted to steam.
FIFTH STROKE (Steam Power Stroke): During the fifth stroke, the steam initiates the second power stroke.
Both valves remain closed. Piston moves from Top Dead Center to Bottom Dead Center.

Current trends in engine development are governed by moreand more stringent emission regulations
and aim at lowering consumption and emissions in order to obtain ever cleaner engines. The efficiency of a
reciprocating internal combustion engine is strongly linked to its expansion ratio since increasing the expansion
ratio allows an increase of the fuel conversion efficiency. However, in traditional internal combustion engines,
the compression ratio is limited due to mechanical stress and combustion issues. Power losses from the engine
are mainly due to thermal losses. For most engines, either spark ignition engines or compressed ignition engines,
around one third of the energy available in the fuel is lost inside the cylinder due to heat losses through
[2] Kiran P, ―A Feasibility Study on Waste Heat Recovery in Six Stroke IC Engine‖ International Journal
on MechanicalEngineering and Robotics (IJMER), Volume-1, Issue-1,2013.
Waste heat recovery from internal combustion engines (ICE) is one of the opportunities for
economizing of energy consumption. In an ICE, a great amount of fuel energy is wasted in the form of heat due
to thermal limitations. To recover the waste heat, various methods are being adopted. During every cycle in a
typical four stroke engine, piston moves up and down twice in the chamber, resulting in four total strokes and
one of which is the power stroke that provides the torque to move the vehicle. But in a six stroke engine there
are six strokes and out of these, there are two power strokes. The automotive industry may soon be
revolutionized by a new six-stroke design which adds a second power stroke, resulting in much more efficiency
with less amount of pollution.In a six stroke engine, when the combustion chamber temperature reaches approx.
400 °F (200°C), just before the fifth stroke fresh water is injected directly into the hot combustion chamber

through the engine’s fuel injector pump, which is quickly turned into a superheated steam, which causes the
water to expand to 1600 times its volume and forces the piston down for an additional power stroke. By the
utilization of the waste heat, the performance of the internal combustion engine is considerably increased. With
the utilization of the waste heat of internal combustion engine the world energy demand on the depleting fossil
fuel reserves would be reduced. The fuel efficiency would be increased by the development of six stroke engine
with the same amount of fuel the internal combustion engine would give more mileage and it would relief
growing demand.

InternalCombustion Engine‖ Thermal Engineering department, SVMIT, Bharuch-392001, Gujarat, INDIA-
2014.
The engine captures the waste heat from the four stroke Otto cycle or Diesel cycle and uses it to get an
additional power and exhaust stroke of the piston in the same cylinder. Designs either use steam or air as the
working fluid for the additional power stroke. As well as extracting power, the additional stroke cools the engine
and removes the need for a cooling system making the engine lighter and giving 40% increased efficiency over
the normal Otto or Diesel Cycle.The pistons in this six stroke engine go up and down six times for each
injection of fuel. These six stroke engines have 2 power strokes: one by fuel, one by steam or air. The six stroke
engine modification promises dramatic reduction in fuel consumption of an internal combustion engine. The
fuel efficiency of the engine can be increased and also the valve timing can be effectively arranged to extract
more work per cycle. The brake thermal efficiency of four stroke two cylinder diesel engine can increases by
modified its some component and convert into six stroke engine.Better scavenging is possible because exhaust
of first cylinder exhaust is become a inlet of second cylinder during the fifth stroke and its work as second
power stroke the exhaust during the sixth stroke.
Basic Parts Modification
1. Crankshaftto Camshaft Speed Ratio:
The original angular speed of the camshaft is one-half that of the crankshaft, such that the camshaft rotates once
for every two revolutions (or four strokes) of the crankshaft. The crankshaft pulley of the unmodified (4-stroke
engine) engine has a 21 tooth and camshaft pulley of the engine has a 42 tooth. In conventional four stroke
engine, the crankshaft must rotate720° while the camshaft rotates 360° to complete one cycle. For six-stroke
engine, the crank shaft must rotate 1080°to rotate the cam shaft 360° and to complete one cycle. Hence their
corresponding speed ratio is 3:1. In modified engine a camshaft pulley has a 42 tooth which is same as that
was in unmodified (4-stroke engine) engine and crankshaft pulley has a 14 tooth which is 1/3 of the camshaft
pulley because the rotation ratio of crankshaft to camshaft is 3:1 in six stroke engine. So it is necessary to keep
camshaft pulley three times bigger than crank shaft pulley
2. Modificationin Inlet And Exhaust Manifold:
In given four stroke engine there is common inlet manifold through which required quantity of fresh charge
from atmospheric air is sucked due to movement of piston and vacuum creation and mixed with the fuel for
proper combustion The common inlet manifold of four-stroke engine parted by welding a plate between the
common inlet manifold. The plate welded between the inlet manifold is of aluminium. Because manifold is
made of aluminium. The main benefit of this manifold is exhaust gases come out at high temperature so it will
preheat the inlet air so increase the combustion rate.

3. Camshaft Modification:
In six stroke engine piston moves three times up and down so for that valve open two times in a one revolution
of a complete cycle. So that in place of four stroke engine in six stroke engine two lobes is provided.

Advantages And Disadvantages
An operating efficiency is of approximately 50%, hence the large reduction in specific consumption.
The specific power of the six-stroke engine will not be less than that of a four-stroke petrol engine, the increase
in thermal efficiency compensating for the issue due to the two additional strokes. Chemical, noise and thermal
pollution are reduced. There occurs no problem in combustion due in flammability difference in six stroke
engine. Better combustion and expansion of gases that take place over 540° of crankshaft rotation, 360° of
which is in closed combustion chamber, and 180° for expansion. It has less inertia due to the lightness of the
moving parts. [6] It has also some disadvantages as brake power & indicated power per cycle per cylinder is
comparatively lesser. The Engine size increases due to number of cylinders & additional components. These
engines are complex in design and hence higher manufacturing cost.
III. Conclusion
From the above data the concept and working of the six-stroke engine can be understood. Six stroke
engines with all the desired qualities as better from four stroke engines will be hitting the market soon. Reducing
fuel consumption and pollution without any effect on performance will reassessed the concept of automobile.
Only improvements of the current technology can help it progress within reasonable time and financial limits.
The six-stroke engine fits perfectly into this view. Its adoption by the automobile industry would have a good
impact on the environment and world economy.
