| 總結: | In
case of petrol engine, the mixture of fuel and air in the correct ratio
prepared in the carburetor entering into an engine cylinder during suction, but
in case of the suction charge is only air from filter. Mixing of air and fuel
in diesel engine takes place inside the cylinder at the end of compression.
Improved design of combustion chamber of diesel
engine is obtained by imparting Squish and Swirl effects for the modifying
part. Also the modifying part must include the hot spot regions at proper
locations to improve the performance of an engine and also reduce harmful
emissions from exhaust. Therefore, to include the hot spot regions at proper
locations, it is required to measure the temperature values at different locations/coordinates
on the surface exposed to combustion chamber with the help of thermocouples.
