Abstract
【 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.
