摘要
探讨了有二次空气供给的热反应净化器(A)、有二次空气供给与EGR功能的热反应净化器(B)、有二次空气供给、EGR、热反应净化和催化转化等功能的排气净化装置(C)等3种方案对排气中CO,HC和NOx的净化效果;发动机台架试验研究结果表明,方案C对于汽油机排气中的CO,HC和NOx具有最佳的综合净化效果。
This paper discussed three devices' purificatory effects on exhaust emissions, such as HC, CO and NOx. The device A is a thermal reaction purifier with secondary air support. The device B is a thermal reaction purifier with secondary air support and EGR. The device C is a thermal reaction purifier with secondary air support, EGR and catalytic converter. The test result from study on the engine rig shows that the device C is optimal in three devices for reducing HC, CO and NOx emissions.
