Abstract: The social environment of air pollution is an important problem, and each engine manufacturer has been directed to investigate emission control. In this study particulates, divided between dry soot and soluble organic fraction (SOF), and gaseous emissions were measured under a variety of steady-state operating conditions from direct-injection (DI) diesel engines using a dilution tunnel to clarify the particulate emission characteristics. From these results the relationship between dry soot and black smoke, and the relationship between SOF and hydrocarbons were analysed and each correlation was clarified. Results also indicate that the particulate can be estimated from black smoke and hydrocarbons. A simple measuring method is offered for development testing.

Keywords: air pollution; black smoke; diesel engines; emission control; hydrocarbons; particulate emissions; dry soot; soluble organic fraction; vehicle emissions.
