乙醇-柴油发动机可调参数对动力性影响研究

Research on the Adjustable Parameter of the Alcohol-diesel Engine to the Motivity Influence

乙醇柴油的不同配比、供油提前角、喷油压力、喷油泵柱塞直径及行程燃烧室的型式等参数的调整,对乙醇柴油混合燃料的柴油机动力性、经济性、排放指标等有重要的影响.参数调整后的乙醇柴油发动机经济性和排放指标皆优于纯柴油发动机,动力性略低于纯柴油发动机.

The adjustment of parameters ,including alcohol diesel different ratio, supply advance angle, injection pressure, injection pump plunger diameter and itinerary, as well as the type of combustion chamber, affects on the type of mixed fuel alcohol diesel engine power, economy, emissions targets , and so on. After parameter adjustment ,the diesel engine emissions and economic indicators are better than pure diesel engines.and power is slightly less than pure diesel engines＇.
