摘　　要：对北京市不同车型的CNG公交车的用气指标进行了统计计算,得到了单机、双机、双层3种车型的用气指标,对比了CNG公交车与燃油公交车的燃料费。每100km耗气量单机车为34.51m3,双机车为48.15m3,双层车为40.96m3。每100km燃油公交车的燃料费为CNG公交车的2.45倍。The statistical calculation of gas consumption index for different types of CNG buses in Beijing City is carried out. The gas consumption indexes for single engine, double engine and double decker buses are obtained. The fuel expense of CNG bus is compared with that of oil-fired bus. The gas consumptions per 100 km for single engine, double engine and double decker bus are 34.51 m^3, 48. 15 m^3 and 40.96 m^3 respectively. The fuel expense per 100 km for oil-fired bus is 2.45 times more than that for CNG bus.
