高原汽油机颗粒捕集器捕集效率的研究进展

Research Progress of Particle Catcher Efficiency in Plateau Gasoline Engine

基于《轻型汽车污染物排放限值及其测量方法(第六阶段)》排放标准正式推出的具体国情,以及我国海拔2 000 m以上的高原地域约占国土面积1/3的实际情况,阐述了高原环境对汽油机尾气排放颗粒的影响因素,同时因为国内外对高原GPF的捕集效率研究甚少,因此阐述了高原环境下的汽油机尾气排放特性与平原环境下GPF捕集效率的影响因子,并对高原GPF的工作效率和捕集效率后期研究进行展望。

Based on the specific national conditions officially introduced in the emission standards of Light Vehicle Emission Limits and Measurement Methods(Phase 6),and the plateau region above 2 000 m in China accounts for about 1/3 of the land area.Expounded the influence factors of plateau environment on the gasoline engine exhaust emission particles, at the same time at home and abroad because of the capture efficiency of GPF on the plateau research, therefore, this paper expounds the plateau environment of gasoline engine exhaust emission characteristics and plain environment under the influence of the GPF capture efficiency factor, and working efficiency of the plateau GPF and capture efficiency later study was discussed.
