Optimization of Thermal Systems
The project of Electronic Cooling System was presented for the Optimization of Thermal System class in April 2009.
Engine Performance Improvement
various methods for improving the engine performance have been discussed. Most significant upon them is to reduce the obstruction in the flow of fresh mixture and burnt products. In addition to this by improving the inlet and exhaust valve timing. Increase in compression ratio and swept volume may also improve the engine parformance

I.C.Engine performance parameters
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.
ηv= (푚 ̇"a/a" )/(푉푑푖푠푝푎푐푒푑 푋 푁/2)
"a"= Inlet density is taken atmospheric air density
N= Number of the cylinder in use

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.
