| 摘 要： | 研究了电控LPG发动机的催化转化器安装位置、点火提前角和怠速转速对催化转化器快速起燃的影响。试验结果表明,催化转化器的位置距排气口近可提高排气温度,大大提高催化转化器的转化效率;推迟点火提前角和提高怠速转速均有利于使催化转化器进入快速起燃状态。

| Abstract: | The effects of converter position,ignition timing and idle speed on catalytic converter light-off behavior were studied on an electronically controlled LPG injection engine.Experimental results show that the position of the converter nearer to the exhaust port,the retard ignition timing and the higher idle speed can promote the catalytic converter light-off. |
