摘要

本文通过对轻型汽车开展WLTC和CLTC工况比对试验,研究了CLTC-P工况下冷起动排放污染物和基础油耗,对比分析了WLTC工况和CLTC-P工况下的排放污染物及综合油耗测试差异.结果表明,WLTC曲线测试条件简单易行,能够较好地模拟城市和高速公路行驶情况,CLTC曲线注重城市行驶情况的模拟,更准确反映了真实驾驶情况.

Abstract

In this paper,the comparative test of WLTC operation condition and CLTC operation condition for light-duty vehicles is carried out,the cold-start emission pollutants and basic fuel consumption under CLTC-P operation conditions are studied,and the differences in emission pollutants and comprehensive fuel consumption test between WLTC operation condition and CLTC-P operation condition are compared and analyzed.The results show that the WLTC curve test conditions are simple and feasible,which can better simulate urban and highway driving conditions,while the CLTC curve focuses on the simulation of urban driving conditions and reflects the actual driving conditions in more accurate manner.
