摘要
为达到模拟汽车在实际道路上行驶的瞬态工况,文章利用底盘测功机,在不同工况下给汽车加载不同的负荷,并进行测试。通过对瞬态工况下排放试验测试数据的处理和分析,得出了汽车尾气排放中CO,HC,NOx在不同速度和加速度变化时的变化趋势与规律。测试结果表明,在行驶速度较低时,尾气中CO和HC的排放量较大,NOx的排放较小;行驶速度较高时,CO和HC的排放量较小,而NOx的排放较大。
In order to simulate transient mode in practical road, using chassis dynamometer, test is conducted in different modes with different loading. By processing and analyzing the emission test data in transient mode, it is concluded that the change trend and nile of emission of CO, HC and NOx in different velocity and acceleration is gained. The test result indicated that in low speed the emission of CO and HC is high and NOx is small; in high speed the emission of CO and HC is small and NOx is high.
