Twice fuel injections affect to Combustion and performance of diesel engine

摘要

In research of diesel engine, fuel repeated injections are used often. In order to prolong heating in pressure process, heighten Pi and decrease P_(max), t_(max). We make some experiments in diesel engine by means of one main injection + one later injection, the results show that indicated mean effective pressure is increased greatly, and NO_X are decreased greatly, in the case of no changing P_(max).
