| 摘 要： | 通过对15辆车采用相同的底盘测功机,分别用汽车排放总量分析系统(VMAS)和定容采样系统(CVS)进行瞬态采样测试,并对测试结果进行了分析。阐述了VMAS由于系统测量精度、系统响应时间、工况变化等因素的影响,使得对HC、CO、CO2和NOx的测量与CVS有不同程度的偏差。但VMAS仍有较好的测试准确性和较低的成本,适用于在用汽油车检测。

| Abstract: | Emission tests of 15 vehicles are conducted on same chassis dynamometer with both VMAS and CVS sampling schemes respectively. The test results are analyzed, which show that due to the effects of measuring accuracy, response time and variation of working conditions, the measurements on HC,CO,CO2 and NOx emissions with VMAS have deviations to different degrees. Nevertheless, VMAS has the advantage of low cost with reasonable accuracy, thus suitable for emission tests for in-use gasoline vehicles. |
