汽油—氢气发动机微机控制供氢与点火系统的研究

A Study on Microprocessor-Controlled Hydrogen Supply and Ignition System of Gasoline-Hydrogen Engine

本文介绍了一种适合车用的汽油-氢气发动机微机控制供氢与点火系统,讨论和分析了电控系统的结构和工作原理,进行了发动机台架试验。加氢后,在整个工况范围内,发动机综合热效率提高5%～20%,汽油油耗率下降5%～36%,有害排放量明显下降。

In this paper,a microprocessor-controlled hydrogen supply andignition system suitable for automobile gasoline-hydrogen engine is introduced,and thestructure and working principle of this device are discussed and analysed.The engineis tested and the test results show that by inducting the hydrogen,the thermal efficiencyincreases by 5%～20%,the specific fuel consumption decreases by 5%—35% and theharmful emission is evidently reduced over whole engine speed range.
