摘要
针对双燃料发动机的特点介绍了电控双燃料系统的原理;并对所研究的双燃料发动机的失效模式及效应进行了分析。性能试验表明:在不对原柴油机喷油角度、压缩比等参数进行任何改动,只增加燃气供应系统和电控双燃料系统的情况下,在75%负荷下天然气的替代率达到83%,经济性好;同时,排放较纯柴油有较大的改善;发动机的排温、最高燃烧压力及调速性能与柴油机的相近。
Based on the characteristics of duel fuel engines, the principle of electronic control duel fuel system is introduced. The failure mode of the duel fuel engine and its effect is analyzed. Performance test shows that： without any changes to parameters such as original diesel engines injection angle and com- pression ratio, only with the modification of gas supply system and electronic control duel fuel system, the engine can achieve 83% replacement ratio of natural gas under 75% load, and boasts good economic per- formance; meanwhile, the emission is tremendously improved; the exhaust temperature, maximum combustion pressure and speed governing performance are similar to the diesel engine＇s.
