发动机单双火花塞点火性能对比研究

摘要

Combustion experiments studies ahout performance of single spark plug and dual spark plug were conducted on a conventional four-stroke motorcycle engine. By comparing and analyzing the comhustion pressure signals gathered by cylinder pressure sensor in two cases , the results show that the dual-spark plug ignition not only helps to improve the dynamic performance of the engine, but also reduce cyclical variation obviously.%在一台传统的四冲程摩托车发动机上进行了单火花塞和双火花塞点火性能的试验研究,通过对两种点火情况下压力传感器采集的气缸燃烧压力信号的比较分析.结果表明,采用双火花塞点火不但有利于发动机动力性能的提高,而且使发动机的循环变动率大大降低,明显改善了发动机的性能.
