4 stroke petrol engine and 4 stroke diesel engine Komal Kotak
This presentation is all about four stroke petrol engine and four stroke diesel engine from the subject elements of mechanical engineering in mechanical engineering in first year of mech. engineering.
PPT describes the engine performance parameters of the I.C. engine.
Engine performance is an indication of the degree of success of the engine performs its assigned task, i.e. the conversion of the chemical energy contained in the fuel into the useful mechanical work. The engine performance is indicated by the term efficiency, η. Five important engine efficiencies and other related engine performance parameters are:
Power
Indicated Thermal Efficiency (ηith)
Brake Thermal Efficiency (ηbth)
Mechanical Efficiency (ηm)
Volumetric Efficiency (ηv)
Relative Efficiency or Efficiency Ratio (ηrel)
Mean Effective Pressure (Pm)
Specific Fuel Consumption (sfc)
Fuel-Air or Air-Fuel Ratio (F/A or A/F)
Calorific Value (CV)
Power:-
The main purpose of running an engine is to obtain mechanical power.
Brake Power (B.P.)
The power developed by an Engine at the output shaft is called the brake power.
Brake Power= Brake Workdone/Time
B.P.=BWD/sec.
Indicated power (I.P.)
The total power developed by Combustion of fuel in the combustion chamber is called indicated power.
Indicated Power= Indicated Workdone/Time
I.P.=IWD/sec.
Frictional Power (F.P.)
The difference between I.P. and B.P. is called frictional power (f.p.).
FP = IP – BP
Thermal Efficiency (ηth)
Thermal efficiency is the ratio of Power to energy supplied by the fuel.
ηth= Power/ Energy
In I.C. Engine, thermal efficiency can be classified into two categories i.e.
Indicated Thermal Efficiency (ηith)
Indicated thermal efficiency is the ratio of indicated power to the heat supplied or added.
ηith= IP/Qs
2. Brake Thermal Efficiency (ηith)
Brake Thermal Efficiency is the ratio of brake power to the heat supplied or added.
ηbth= BP/Qs
Volumetric Efficiency (ηv)
This is one of the most important parameters which decide the performance of four-stroke engines. Four stoke engines have distinct suction stoke, volumetric efficiency indicates the breathing ability of the engine.
Volumetric efficiency is defined as the ratio of actual flow rate of air into the intake system to rate at which the volume is displaced by the system.

COOLING SYSTEM
1) Need for cooling system (INTRODUCTION)
During the process of converting thermal energy to mechanical energy high temp are produced in the cylinder of the engine as a result of the combustion process. A large portion of the heat is transferred to the cylinder head and walls, piston and valves. Unless this excess heat is carried away and these parts are adequate cooled, the engine will be damaged. A cooling system must be preventing damages to vital parts of the engine, but the temperature of these components must be maintained within certain limits in the order to obtain maximum performance from the engine. Hence a cooling system is needed to keep the engine from not getting so hot as to cause problems and yet to permit it to run hot enough to ensure maximum efficiency of the engine. The duty of cooling system, in other word, is to keep the engine from getting not too hot and at the same time not to keep it too cool either.
2) Characteristics of efficient cooling system
The following are the two main characteristics desired of an efficient cooling system
1) It should be capable of removing about 30% of heat generated in the combustion chamber while maintain the optimum temp of the engine under all operating conditions of engine.
2) It should remove heat at a faster rate when engine is hot. However during starting of the engine the cooling should be minimum, so that the working parts of engine reach their operating temperature in short time.
3) Type of cooling system
In order to cool the engine a cooling medium is required. This can be either air or a liquid accordingly there are two type of systems in general use for cooling the IC engine. They are
1) Liquid or indirect cooling system
2) Air or direct cooling system
4) Liquid cooled systems
In this system mainly water is used and made to circulate through the jackets provided around the cylinder, cylinder-head, valve ports and seats where it extracts most of the heat.
It consists of a long flat, thin-walled tube with an opening, facing the water pump outlet and a number of small openings along its length that directs the water against the exhaust valves. The fits in the water jacket and can be removed from the front end of the block.
The heat is transferred from the cylinder walls and other parts by convection and conduction. The liquid becomes heated in its passage through the jackets and is in turn cooled by means of an air-cooled radiator system. The heat from liquid in turn is transferred to air. Hence it is called the indirect cooling system. Water cooling can be carried out by any of the following five methods
1) Direct or non-return system
2) Thermosyphone system
3) Forced circulation cooling system
4) Evaporative cooling system
5) Pressure cooling system
4.1) Direct or non-return system
This system is useful for large installation where plenty of water is available. The water from a storage tank is directly supplied through the inlet valve to
Do you know what is engine, how many types of engines are available now. How conversion of energy takes place from chemical energy to mechanical energy or useful work. Here engine classified according to their combustion, working stroke, arrangement of piston, fuel used for combustion and on the basis of ignition system. 4-stroke petrol engine and 4-stroke diesel engine are described briefly with all 4-strokes which are completed during power conversion process. 2-stroke engine or scooter engine is also described briefly with the complete details of combustion, charge( petrol,diesel ) filling process and how all 4 stroke process(suction, combustion,power stroke, exhaust) completed in 2 stroke engine.
IC ENGINE TESTING
At a design and development stage an engineer would design an engine with certain aims in his mind. The aims may include the variables like indicated power, brake power,
brake specific fuel consumption, exhaust emissions, cooling of engine, maintenance free operation etc. The other task of the development engineer is to reduce the cost and
improve power output and reliability of an engine. In trying to achieve these goals he has
to try various design concepts. After the design the parts of the engine are manufactured for the dimensions and surface finish and may be with certain tolerances. In order verify the designed and developed engine one has to go for testing and performance evaluation of the engines.
Thus, in general, a development engineer will have to conduct a wide variety of engine
tests starting from simple fuel and air-flow measurements to taking of complicated
injector needle lift diagrams, swirl patterns and photographs of the burning process in
the combustion chamber. The nature and the type of the tests to be conducted depend
upon various factors, some of which are: the degree of development of the particular
design, the accuracy required, the funds available, the nature of the manufacturing
company, and its design strategy. In this chapter, only certain basic tests and
measurements will be considered.
After studying this unit, you should be able to
• understand the performance parameters in evaluation of IC engine
performance,
• calculate the speed of IC engine, fuel consumption, air consumption, etc.,
• evaluate the exhaust smoke and exhaust emission, and
• differentiate between the performance of SI engine and CI engines.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

11. No -Fault Warranty
Motors with frame sizes 215T and smaller are covered under a “No-
Fault” warranty. This warranty claim is offered one time, per end-user,
per application. If there is more than one failure, please contact the
Service Department for review. The following must be sent to the WEG
Service Department to process a “No-Fault” warranty claim.
• Original nameplate from the failed motor (or, for a Shark-line motor, its
terminal box cover)
• Copy of the original WEG invoice or invoice # for the failed motor
• Brief description of the failure for quality control purposes
• Please send request no later than 30 days after failure.
Warranty on Larger Motors
WEG Electric requires that motors larger than 215T frame be inspected
by a WEG Authorized Service Center, or if none is available, an EASA-af-
filiated service shop. Depending on the inspection results, WEG will
decide whether to cover the motor under warranty. Prior to a decision
being made on a claim for warranty, the following are required from the
service shop and customer.
• Completed EASA inspection report
• Repair Quote
• Copy of the original WEG Invoice or WEG Invoice Number
• For Frame 215T and above, photos of the failure in JPEG format
suitable for e-mailing
The inclusion of photos allows WEG to properly evaluate the details of
your claim, as well as to ensure that any data sent to our factory Quality
Control engineers are fully understood. The warranty claim will be evalu-
ated after receipt of the above items. Upon review of the claim, the WEG
Service Department will make contact and advise how to proceed. The
service shop should not remove the nameplate nor make repairs without
being requested to do so by a WEG Service Department representative.
NOTE: For all Ingersoll-Rand motors, please contact the WEG Service
Department prior to any inspection.
Communication
Correspondence with the WEG Service Department may be via e-mail,
fax or regular mail. Please keep a photocopy of all nameplates for your

Warranty Period:
• The standard warranty for WEG products is 18 months from the
invoice date.
• For General Purpose TEFC and ODP Premium Efficiency motors the
warranty is 36 months from the invoice date.
• For IEEE 841 motors, the warranty is 60 months from the invoice date.
Authorized Service Centers:
WEG has service centers around the world to meet the needs of our
customers. Information regarding the nearest service center can be
found on our web site at www.weg.net/us or by calling 1-800-ASK-4WEG
(1-800-275-4934). Any warranty repair by a service shop must be
pre-approved by WEG.
Warranty Service:
If a WEG product requires warranty service due to defective materials or
workmanship, WEG will, at its option, either repair or replace the defec-
tive product. By “replace”, WEG means the original purchaser’s account
will be credited for the cost on the WEG invoice (less freight). If warranty
is granted, and replacement is specified, the motor’s nameplate must
be sent to the Service Dept. Warranty is applied to products that have
been, at all times, properly maintained and operated or used under
normal operating conditions for which the product was designed. WEG is
not responsible for any expenses incurred in installation, removal from
service, transportation (freight) or consequential expenses.
Limitation of Warranty:
THE FOREGOING WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL
OTHER WARRANTIES OF QUALITY AND PERFORMANCE, WRITTEN, ORAL
OR IMPLIED, AND ALL OTHER WARRANTIES INCLUDING ANY IMPLIED

PURPOSE OR ARISING FROM COURSE OF DEALING OR USAGE OF TRADE
ARE HEREBY DISCLAIMED BY WEG. THE FOREGOING OBLIGATION TO RE-
PAIR OR REPLACE WEG PRODUCTS OR PARTS SHALL BE THE SOLE AND
EXCLUSIVE REMEDY OF THE PURCHASER, ITS CUSTOMERS, OR USERS
OF THE PRODUCTS OR PARTS.
Proper Storage of Motors:
When motors are not immediately installed, they should be stored in
their normal upright position in a dry even temperature location, free
of dust, gases and corrosive atmosphere. Inactive motors tend to expel
grease from between the bearing surfaces, thereby removing the
protective film that impedes metal-to-metal contact. At least once per
month shafts should be rotated in accordance with WEG’s installation
and maintenance manual. Motors stored for a period exceeding one
year should have the bearings re-lubricated in accordance with the WEG
motor installation and maintenance manual.

duty. Severe Duty is standard with WEG
W22 motors.
High performance with maximum energy efficiency is the goal of the WEG
W22 electric motor. High efficiency and low cost of ownership throughout
the entire motor lifetime have been the basis for the W22 development.
A design created to maximize performance and energy savings. Optimized
cooling system, large and accessible terminal box, exclusive bearing seal
system, low vibration levels, and a 1.25 service factor are just a few of
many STANDARD features of our W22 motors.
