Comparative analysis of emission and energy consumption of plug-in hybrid electric vehicle on actual road driving
插电式混合动力汽车实际道路行驶的排放与能耗对比分析

摘要

为了解插电式混合动力汽车在实际道路正常行驶过程中不同电量区间下的排放情况，本文采用了便携式车载排放测试设备对一辆满足国五法规的插电式混合动力汽车（比亚迪宋）进行实际道路行驶排放试验。分析车辆在不同电量区间下、电量消耗模式与充电模式的排放与能耗差异。试验结果表明：当电量处于80%-65%区间时，车辆气态污染物的排放与油耗明显降低，表现出较好的排放特性和燃油经济性。当车辆处于充电状态时，发动机给车辆提供动力的同时还要给蓄电池充电，使得发动机运行负荷较高，导致车辆排放大幅度增加。

Abstract

In order to understand the emission of plug-in hybrid electric vehicle (PHEV) in different electric quantity intervals during the actual road running, this paper adopts portable vehicle-mounted emission testing equipment to carry out the actual road running emission test on a PHEV (BYD Song) that meets the national five regulations. The emission and energy consumption differences of vehicles in different electric range, electric consumption mode and charging mode are analyzed. The test results show that when the electric quantity is in the range of 80%-65%, the gaseous pollutant emission and fuel consumption of the vehicle are significantly reduced, showing better emission characteristics and fuel economy. When the vehicle is in charging state, the engine to provide power to the vehicle at the same time to charge the battery, so that the engine running load is high, resulting in a significant increase in vehicle emissions.
