| 摘 要： | 汽油机颗粒物捕捉器(GPF)能有效地捕集汽车排气中的颗粒物,其过滤效果可接近90%。EMS通过对车辆运行过程中碳颗粒(soot)的生成速率以及系统控制再生过程的碳颗粒(soot)的燃烧速率积分计算,进而计算出GPF中累积的颗粒物的质量。因此对碳颗粒的累积质量及再生质量的计算极其重要。

| Abstract: | The Particulate of the gasoline vehicles exhaust could be eff ectively fi ltered with Gasoline Particulate Filters(GPF),and the fi ltration eff ect is close to 90%.EMS calculates the mass of particulate matter accumulated in GPF by integrating the formation rate of soot during vehicle operation and the combustion rate of soot during regeneration is controlled by system.Therefore,it is very important to calculate the cumulative mass and regeneration mass of carbon particles. |
