摘　　要：通过测量两台典型车用柴油机 4 8个工况下的微粒排放与消光式烟度 ,得出了排气微粒、微粒干组份以及微粒的可溶组份与消光式烟度之间的关系 。The relationships between exhaust particulate matter(PM),its dry soot fraction(DS)and soluble organic fraction(SOF)and smoke opacity were obtained from measurements on 2 typical automotive direct injection diesel engines under 48 different operation conditions Empirical expressions were also derived by regression of measured data
