设计了柴油机排气微粒测量装置 ,对 S195非直喷式柴油机的排气微粒数量浓度、表面积浓度、体积浓度进行了测量 ,发现了非直喷式柴油机排气微粒数量浓度呈双峰分布的特性。通过研究柴油机排气微粒在不同转速和负荷下的物理分布特性 ,对微粒的生成机理进行了探讨
A diesel exhaust particle measuring device was designed to measure the exhaust gas particle concentration, surface area concentration and volume concentration of S195 non-direct injection diesel engine. It was found that the emission concentration of non-direct injection diesel engine was bimodal . By studying the physical distribution characteristics of diesel engine exhaust particles under different rotational speeds and loads, the formation mechanism of microparticles is discussed
