1.引言气体燃料发动机是内燃机的始祖,最早出现于19世纪后半期.但是,由于当时燃料生产仍以煤炭为主,石油、气体燃料资源开发不足,大大地限制和阻碍了气体燃料发动机的发展.随着石油类液体燃料的开发、国外燃料生产构成发生变化和压燃式发动机的出现,在20世纪前半期,气体燃料发动机便让位给液体燃料发动机了. 随着石油和天然气工业的相继兴起,煤炭在燃料构成中的地位不断下降,石油、天然气
1. Introduction Gas-fueled engines were the first ancestors of internal combustion engines and first appeared in the latter half of the 19th century. However, the development of gas-fueled engines was greatly restricted and hampered by the fact that fuel was still mainly coal at that time and oil and gas fuel resources were underdeveloped With the development of oil-based liquid fuels, changes in the composition of foreign fuel production and the advent of compression ignition engines, gaseous fuel engines gave way to liquid-fuel engines in the first half of the twentieth century.With the succession of the oil and gas industry Rise, coal’s declining position in the composition of the fuel, oil, natural gas
