摘要
通过发动机性能试验 ,对引燃油量和供油提前角对发动机低负荷排放的影响进行了深入的探讨。试验表明低负荷时引燃油量可适当增加以改善排放 ;供油提前角适当提前可降低HC和CO排放 ,又不会使NOx 排放增加很多。
In the study, engine tests were carried out on pilot fuel and fuel supply advanced angle. It was found that at lower loads increasing pilot fuel appropriately improved emissions. Advancing fuel supply advanced angle appropriately reduced HC and CO emissions, and NO x emission didn′t increase excessively.
