| 摘 要： | 对空气和天然气供气系统的2个参数-进气温度和空燃比进行了发动机试验，空燃比的调节包括进气节流和停缸2种方式。试验结果表明，适当提高进气温度和合适的进气节流量都可以降低THC和CO排放，但NOx排放会增加，在低负荷时采用停缸技术，可以很好地改善发动机的排放。

| Abstract: | In the study,engine tests were carried out on two parameters of air and natural gas supply system,which are intake temperature and A/F ratio including intake throttling and skip firing.It was found that increasing intake temperatue appropriately and seemly throttling quantity reduced THC and CO emissions,but increased NO x emission.At lower loads skip firing improved the emissions of the engine commendably. |
