气体燃料及其应用于发动机的研究与发展

THE PRESENT STATUS AND TREND OF GASEOUS FUELS AND THEIR APPLICATION TO I. C. ENGINES

本文介绍了几种常用气体燃料以及它们用作内燃机燃料时的有关性质,综述了国际上气体燃料发动机的研究进展和最新发展动向,介绍了我国开发和研制气体燃料发动机的现状。针对我国的实际情况,提出了应寻求新途径来提高煤气热值、研制高效的控制系统、优化发动机的参数等今后亟需解决的一些问题。

Properties and characteristics of various gaseous fuels for internal combustion engines and development work in gas engines both abroad and domestically were reviewed in this paper. To meet demands in the Chinese rural areas, some problems of high priority were identified; ( 1 )Looking for new methods to elevate heating values of gaseous fuels for I. C. Engines; ( 2 ) Developing more flexible and effective controls that will allow optimum performance over a wide range of fuels; ( 3 )Further research being still needed to contribute towards reducing the tendency of engines to knock particularly with some low MN value gaseous fuels.
