Quantitative Relations of Combustion in a D.I. Diesel Engine (Rapid Combustion Period) 891918
On the basis of heat release progresses for the various operating conditions acquired from a quiescent directinjection diesel engine, the quantitative relations between the quantities relating to the combustion in the rapid combustion period are examined by experiment. A couple of linear relations causing a particular feature of the burning process in this combustion period and some other relating fundamental properties are found and discussed. The experimental equations for the principal relations are also given. Acquired results illustrate the existence of macroscopic quantitative relations holding in the combustion process in diesel engines.
