摘要：Particulate emission of diesel engines which seriously affects environment and human health is a hot topic in recent diesel engine researches. In this article, a diesel engine particulate sampling devise was designed, particulate sampling experiments were done in different positions with different exhaust temperatures of a diesel engine exhaust pipe. The temperature difference was expected to preliminarily simulate the exhaust cooling process in some exhaust after-treatment apparatus. For each particulate sample, the insoluble organic fraction (IOF) and soluble organic fraction (SOF) was separated. With GC/MS technique, the fractions of SOF were analyzed. The experimental results showed that under rated speed or maximum torque speed with medium or small load, IOF is the main fraction of particulate. For a changeless mode, with the decreasing of sampling temperature, SOF mass content in particulate increased, at the same time, more kinds of fractions, more alkanes content and less aromatic hydrocarbons content were detected.
