插电式串联混合动力汽车的经济性与排放性

Fuel economy and emissions from series plug-in hybrid electric vehicle

基于不同的循环工况(市区测试循环,新欧洲测试循环,特大市区测试循环,中国典型城市乘用车快速道路循环与普通道路循环),利用CRUISE软件进行仿真计算,比较了插电式串联混合动力汽车与原型车的经济性和排放性,考查了串联PHEV的节油效果和减排效果。计算结果表明,在不同循环工况下,串联PHEV最低的百公里油耗仅为2.1L,比原型车降低了62%;同时,串联PHEV也大大降低了污染物的排放量,相对于国家第四阶段机动车污染物排放标准(简称国四排放标准),HC,CO,NOx的排放量分别降低了61%,48%,41%。

The comparisons of fuel economy and emissions between the series plug-in hybrid electric vehicle（PHEV） and the equivalent prototype vehicle were simulated using the CRUISE code under different driving cycles,such as urban driving cycle（UDC）,new European driving cycle（NEDC）,extra-urban driving cycle（EUDC）,and Chinese city driving cycles on expressway and common road for passenger car,to investigate the energy-saving and emission reducing effects of series PHEV.The results showed that the minimum fuel consumption of PHEV in different driving cycles is about 2.1 L/100 km which is 62% less than that of the prototype vehicle.At meantime,the series PHEV emits significantly less emissions,its emissions of HC,CO and NOx is reduced by 61%,48% and 41%,respectively by comparison with the corresponding Chinese emissions standard（IV）.
