Abstract :Design and control of recently developing engines have much important towards better fuel economy and reduction in exhaust emissions from an engine. Since the ignition takes place due to high compression insert ignore into journalissuearticles values(or); self ignition of temperature in case of diesel engines, the temperature distribution and heat flux on the combustion chamber surface are an important phenomenon.   While modifying the profile of combustion chamber of diesel engine, it is important to relocate the hot spot regions on the combustion chamber surface which supports combustion initiation. With these hot spot regions on combustion chamber surface regulates/controls ignition delay period which results in controlled detonation. In diesel engines, controlled detonation which in turn improves engine performance and reduced emissions. Therefore, to include the hot spot regions at proper locations, it is required to measure the temperature values at different locations/coordinates with the help of thermocouples on the cylinder head surface exposed to combustion chamber. Also the adiabatic flame temperature, the engine performance parameters, heat balance date, convection and radiation heat transfer related terms were calculated and analyzed
