摘　　要：本文通过测量一台车用直喷柴油机50个工况下的微粒排放和烟度,得出了排气微粒及其干组份与滤纸烟度之间的关系以及微粒的可溶组份与排气中气态总碳氢之间的关系,并且回归成经验公式。The relationships between exhaust particulates and Bosch smoke number(FSN) between dry soot fraction of particulates and FSN, and between soluble organic fraction (SOF) and gaseous THC emission were obtained from measurements on an automotive direct injection diesel engine under 50 different operating conditions. Empirical expressions were derived from regression of measured data.
