摘要
在摩托车化油器后采用电控节油净化器进行适当的机前二次空气补给来稀释、调整混合气,加大空燃比,对于降低CO、HC排放具有明显效果,具有实用价值;在摩托车催化转化器前引入机后二次空气补给可以达到提供O2、提高催化转化器转化效率和使之快速起燃的目的,从而有效降低摩托车的排放。
It is striking and practicable in reducing CO and HC for motorcycle to employ electrically-controlled economy purification device at its rear part for properly conducting secondary air supplement treated before air + fuel entering into cylinder to dilute and adjust gas mixture and increase the air-fuel ratio. If the secondary air is induced into motorcycle catalystic converter treated after exhaust gas dischages from cylinder, the conversion efficiency will be greatly improved with O2 provided and lighting-up quickened.
