阻力加载对乘用车WLTC循环排放及油耗影响
|
摘要
基于一辆搭载1.4 L涡轮增压汽油机的乘用车汽车,通过WLTC循环工况测试,分别对比研究了不同阻力加载a和b对整车试验循环排放及油耗的影响。研究发现:阻力加载b在中低速阶段的阻力相对阻力加载a比较小,对排放和油耗均有一定程度的改善;但是第四阶段阻力加载b相对阻力加载a较大,排放和油耗均增加;但是整体综合排放和油耗均有改善。
Studied the effects of resistance load on emission and fuel consumption during WLTC cycle base on a vehicle equipment a turbo charged 1.4 L engine. Research suggest that the emission and fuel consumption will be improved during the first phase、second phase and third phase when use the load b,because the resistance load is smaller than load a. while the emission and fuel consumption will be deteriorated,because of the load was larger than load a;but the Comprehensive emission and oil consumption were improved.
