点燃式甲醇发动机的性能和排放

Investigation on Performance and Exhaust Emissions of a Spark-Ignition Methanol Engine

本文通过在CA1102单缸点燃式发动机上燃用全甲醇的试验,研究了进气预热、压缩比、空燃比和点火定时对全甲醇发动机性能和排放的影响。通过稀燃和推迟点火改善了效率和NO_x排放之间的折衷关系,为高效率低污染点燃式全甲醇发动机的开发作出了贡献。

The effects of intake mixture heating, compression ratio, air-fuel ratio and ignition timing on performance and exhaust emissions were investigated by dynamometer tests on a CA1102 single-cylinder spark-ignition engine fueled with neat methanol. The compromise between efficiency and NO_x emission was improved by lean mixture combustion and ignition delay. A contribution to the development of efficient and neat methanol engines is made.
