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 (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
