摘要
在神龙富康化油器汽车改为汽油/CNG 两用燃料汽车后，整车重量增加55kg．动力性下降19%，CO 排放增大达 25．6倍，HC 下降28%．所以化油器式汽车在改用天然气后应对燃烧系统进行必要的调整，否则改用天然气的优越性不 能充分的体现出来。而调整后再燃用汽油时就可能引起爆震或残余废气过高。因此应尽可能缩短汽油/CNG 两用燃料 汽车的过渡时间，加快 CNG 加气站的建设，将两用燃料汽车改为纯 CNG 汽车。
After a carburetor vehicle is replace by gasoline/CNG （Compressed Natural Gas）, the weight of vehicle increases 55 kg, output power reduces 19 %. CO emission increases 25.6 times and HC decreases 28 % compared to original vehicle, so combustion system should be adjusted accordingly, otherwise advantages of CNG vehicle can not be achieved completely. It may cause cylinder-knocking and more residual exhausting gas ff gasoline is used again after adjustment, so bi-fuel vehicle is modified into mono-fuel CNG vehicle to shorten period of gasoline/CNG hi-fuel vehicle and step up construction of CNG gas station.
