摘　　要：以配置分电器微机控制电子点火系统的广州本田雅阁F23A1发动机为例,研究了点火系统技术参数对发动机排放的影响,介绍了排放测试系统的组成及测试方法。试验结果表明,点火系统的火花塞间隙、蓄电池电压、高压线阻抗及点火提前角等技术参数的改变会导致点火能量或点火时间上的改变,从而对HC排放都有一定的影响,而对CO排放影响都不大。Based on the Guangzhou Honda Accord Engine F23A1 equipped with electronic controlled ignition system with distributor,the impacts of ignition system technical parameters on engine emissions are studied and the constitution and testing method of emission testing system are introduced in the paper.The test results show that the change of technical parameters for ignition system such as spark plug＇s gap,battery voltage,high impedance and ignition advance angle could lead to the change of ignition energy or time,which had has some impact on HC emission and little impact on CO emission.
