| Summary: | Based on a plug-in hybrid car equipped with a 1.5L turbocharged direct injection gasoline engine, this paper studies the emission and fuel consumption characteristics of the prototype vehicle under three different cycle conditions, WLTC city, WLTC and CLTC-P. The results show that for the four pollutants: CO, THC, NMHC and NOx, WLTC city cycle emissions are the largest, WLTC cycle emissions are the smallest, CLTC-P cycle emissions are the middle. For N2O, WLTC cycle has the largest combined emissions, CLTC-P cycle combined emissions are the smallest, and WLTC city cycle combined emissions are the center. The combined fuel consumption under WLTC city conditions is approximately 1.3 times the combined fuel consumption under the complete WLTC cycle. The combined fuel consumption under CLTC-P conditions is approximately 1.25 times that of the complete WLTC cycle. The first phase of each cycle is the phase with the highest emissions and fuel consumption.
