Quantitative Relations of Combustion in a D.I. Diesel Engine (Main Combustion Period and After Burn Period)

On the basis of heat release progresses for the various operating conditions acquired from a quiescent D.I. diesel engine, the quantitative relations hold among the values related to the combustion in the period after the end of rapid combustion are examined by experiment. SubjecT_s on a method for dividing the burning period, on the burning characteristics for each period, on the relations among the values, and on the values expressing the mixing function of the fuel spray as well as the burning performance of the period are included. Discussions on the burning mechanism of the fuel spray are also given.
