Characteristics of Combustion and Exhaust Gas and Fuel Consumption In DI Diesel Engine Using Ringed Impingement Wall Head

The engine performance , exhaust gas emission and combustion characteristic on DI diesel engine with a ringed impingement wall were investigated about the effect of EGR in this paper. The ringed wall was attached to the cylinder head near center of combustion chamber in order to enhance the spray diffusivity.

The experimental result was shown that high EGR rate with high temperature reduced remarkably NO, HC, soot and fuel consumption, and also , run the gentle combustion.
