Experimental study on HEV series truck model

Tóm tắt

This study presents the design of a serial HEV model and experimental evaluation of performance, fuel consumption measurement, and pollution emission index. Experimental results of fuel consumption measurement on the same cycle show that fuel consumption in HEV mode is reduced by 36.72% compared to ICE mode. The HEV model has a significantly lower emission index than the ICE internal combustion engine during most of the cycle. During the operating stages, the emission time of the ICE experimental cycle always has a period of emission maintenance at 800 rpm. Both cycles reach a sudden emission level of up to about 1.7%, however, the HEV cycle remains essentially HSU emission-free throughout the first 150 minutes and more than
120 minutes of operation at 1500 rpm of the ICE. The smoke coefficient of the test cycle is within the allowable limits of the national standard QCVN 09:2024/BGTVT.
