对混合动力汽车进行了全球统一轻型车辆测试循环工况(WLTC)和实际行驶污染物排放(RDE)测试,评估了混合动力车辆相对于传统燃油车的减氨效益,同时分析了基于不同混合动力技术路线车辆、不同电量模式下测试得到的NH3排放特征差异.研究发现,混合动力技术对于降低NH3排放存在一定效果,在消耗同等燃料的前提下,采用非插电式混合动力技术NH3排放可下降56.07%,采用插电式混合动力技术可下降 94.43%,可插电式混合动力车辆与不可插电式混合动力车辆NH3排放峰值出现的时刻有所差别,车辆在电量增加模式下因为需燃烧更多的燃料为电池充电,过量空气系数较小,催化器还原环境较强,使NH3排放大于电量消耗模式.
Abstract
World Light Vehicle Test Cycle (WLTC) and Real Drive Emission (RDE) tests were conducted on hybrid vehicles, and compared the ammonia reduction benefits of hybrid vehicles relative to conventional fuel vehicles. It also analyzed the differences in ammonia emission characteristics obtained from different hybrid technology routes and different battery charge modes. The study found that hybrid technology has a certain effect on reducing ammonia emissions. Under the same fuel consumption, the use of non-plug-in hybrid technology can reduce ammonia emissions by 56.07%, while the use of plug-in hybrid technology can reduce ammonia emissions by 94.43%. The timing of the peak ammonia emissions differs between plug-in hybrid vehicles and non-plug-in hybrid vehicles. In the mode of increasing battery charge, the vehicles need to burn more fuel to charge the battery, resulting in a smaller excess air coefficient and a stronger catalyst reduction environment, which leads to higher ammonia emissions compared to the mode of consuming battery charge.
