摘要
在中国城市客车行驶工况条件下,运用车载排放测试技术(portable em ission measurement sys-tem,简称PEMS)研究了某重型混合动力客车在怠速运转时采取停机和不停机两种不同控制策略下的实际排放因子和燃油消耗率.试验研究结果表明,停机模式比不停机模式可提高该车燃油经济性4.6%,但CO排放因子却增加了53.6%;怠速不停机时,HC+NOx排放增加20.6%.同时说明对于混合动力车辆的油耗和排放,特别是排放的评价,应当采取基于整车的评价方法.
Based on city-bus driving-cycle in China, the emission factor and fuel consumption of the heavy-duty hybrid-power vehicle on real-world are evaluated. During the test, the portable emission measurement system（PEMS） is employed and the two different control strategy, stop and non-stop under vehicle＇ s idle, are studied. The results showed that the fuel economic using stop-mode replacing idle is increased by 4.6 percent than using non-stop under idle, and the emission mass ratio of CO is increased by 53.6 percent. Further conclusion is that for hybrid-power bus, the testing method of emission must be based on whole vehicle such as PEMS.
