我国汽车柴油机可见污染物排放试验

The Emissions of Visible Exhaust Pollutants from Domestic Automotive Diesel Engines

为了解我国汽车柴油机可见污染物排放水平,采用AVL438部分流透光式烟度计,按ECE R24法规的要求,对我国四大汽车生产厂家主要汽车柴油机机型进行了全负荷稳定转速和自由加速可见污染物试验。分析了试验结果,并对我国汽车柴油机可见污染物的控制提出了一些建议。

To have a better understanding of the emission level of the visible exhaust pollutants from domestic automotive diesel engines, a survey of the visible emissions from domestic automotive diesel engines has been made. The survey experiments were conducted by using of an Austrian AVL 438 partial-flow smoke opatimeter in accordance with ECE R24 regulation. The diesel engines tested include the major types of automotive diesel engines produced by four main auto manufacturers in China. This paper summarizes the survey and the analyses of the test results. Then some suggestions are made, which will be helpful to the control of the emissions of visible exhaust pollutants from domestic automotive diesel engines.
