点燃式内燃机气体燃料电控喷射技术的研究

A Study on Electronically Controlled Gaseous Fuel Injection in Spark Ignition Engines

气体燃料被认为是很有前途的车用低污染代用燃料。本文对气体燃料进气门电控喷射技术进行了研究，研制了气体燃料喷射系统、电子点火系统和发动机控制系统，对空燃比、压缩比和充气系数等参数对发动机性能的影响进行了试验与分析。

Gaseous fuels are considered as clear alternative fuels for vehicle. In this paper, the electronically controlled gaseous fuel injection was studied. Gas injecting system, electronic ignition system and engine control system were designed for test. The effects of A/F ratio, compression ratio and volumetric efficiency on gas engine performance were investigated.
