在天然气/柴油双燃料复合燃烧特性和规律的研究基础上,本文通过试验及其分析,具体阐述负荷、转速、替代率、柴油供油特性、引燃油量、进气混合气浓度和供油提前角等因素对双燃料燃烧CO、HC和NO_x排放的影响规律。特别指出天然气/柴油双燃料发动机燃烧排放的主要特征、存在的主要问题和解决的途径。
Based on the research of natural gas / diesel dual fuel compound combustion characteristics and laws, this paper elaborates the load, speed, replacement rate, diesel fuel supply characteristics, fuel quantity, intake air mixture concentration and fuel supply advance Angle and other factors on the impact of dual-fuel combustion of CO, HC and NO_x emissions. In particular, it points out the main features of the combustion of natural gas / diesel dual-fuel engines, the main problems and solutions.
