• 摘要：通过柴油机台架试验,对柴油机排气微粒过滤体的微粒捕集特性及阻力特性进行了研究,并对影响过滤体的微粒捕集效率及排气阻力的几种主要因素,如过滤体结构、柴油机转速、负荷等进行了分析,得出了一些有益的结论.

• Abstract：The collection characteristic and the resistance characteristic of the diesel exhaust particulate filter were studied, and the factors, such as the parameters of filter structure, the velocity and the load of the engine and so on, were analyzed according to some experimental results. Some conclusions are obtained. These results can provide some bases to the development and optimum design of the diesel exhaust particulate filter.

• Key words：diesel engine  particulate  filter  characteristic
