怠速起停控制模式重型气电混合动力客车的能耗与排放特征

Energy Consumption and Emission Characteristics of Heavy Duty Gas Hybrid Electric Bus with Idle Start-stop Control Mode

采用天然气公交车和气电混合动力公交车(配怠速起停系统)作为样车,通过整车转鼓试验,考察了中国典型城市公交循环(CCBC)工况下,怠速起停控制模式对燃气消耗量及排放特征的影响。结果表明,与LNG样车相比,气电混合动力样车每100km可节约能源成本17.39元,采用怠速起停系统后,可节约能源成本51.8元;采用怠速起停模式HEV车辆总碳氢排放降低约32%,NOx排放降低44%,颗粒物质量排放下降36%。

With a natural gas bus and a gas hybrid electric bus （with idle start-stop system） as sample vehicles, the effects of control mode for idle start-stop system on the gas consumption and emission characteristics ofvehicle under China City Bus Cycle （CCBC） are investigated. The results show that compared with LNG sample vehicle, the gas HEV sample vehicle can save energy cost by 17. 39 RMB Yuan per 100 km, which will increases to51. 8 RMB Yuan for gas HEV sample vehicle with idle start-stop system. The adoption of idle start-stop mode canreduce THC emission of HEV vehicle by 3 2 % ,N〇x emission by 4 4 % and PM emission by 36 % .
