摘　　要：通过在康明斯6BT5．9发动机柴油中加入某型燃油添加剂的试验表明，添加剂能使沉积在捕集器内的微粒在300～400％时起燃而使捕集器再生。同时分析了不同工况下，微粒累积与再生平衡温度点的变化及再生效果的优劣。对柴油机微粒捕集器再生技术的研究具有一定指导意义。An experiment is carried out on Cummins 6BT5.9 diesel engine with some additive added into diesel fuel, which indicates that the additive can make particulates deposited in diesel particulate filter （DPF） ignite at a temperature of 300℃ to 400℃and then the filter can rejuvenate. In addition, the variation of temperature point at which the accumulation and regeneration of particulates attain balance and the effectiveness of regeneration under different working conditions are analyzed. The study is of certain guiding significance for the research on the technology of diesel particulate filter regeneration.
