摘　　要：由于对汽车尾气中的颗粒物排放的规定,颗粒物捕集器(GPF)通常被用来去除尾气中的颗粒物,因此需要一种新型的颗粒物传感器来准确监测颗粒物排放。该文使用的压差传感器(DPS)和高温传感器(HTS)的组合传感器具有足够的耐热性和坚固性,能经受住恶劣的排气环境。能够达到检测GPF碳负荷和GPF再生策略的制定,以满足监管排放限制的要求。Due to the regulations on particulate emissions from automobile exhaust,gasoline particulate filter(GPF)is usually used to remove particulate matter from exhaust,so a new type of particulate matter sensor is needed to accurately monitor particulate matter emissions.The combination of differential pressure sensor(DPS)and high temperature sensor(HTS)used in this paper has sufficient heat resistance and robustness to withstand the harsh exhaust environment.It can detect GPF carbon load and formulate GPF regeneration strategies to meet the requirements of regulatory emission limits.
