本文首先报导了一台非直喷轻型柴油机485Q排气微粒的物理特性的实验结果。接着叙述了一种泡沫陶瓷排气微粒后处理器的研制工作。485Q柴油机台架试验表明,泡沫陶瓷滤芯可降低柴油机微粒排放量50％以上。当排气温度超过450～480℃时,已沉积在滤芯上的微粒可自行燃烧,使滤芯获得再生。在柴油中添加少量某些金属有机物,再生温度可降低。 This paper first reports the experimental results on the physical properties of a 485Q exhaust particle for a non-direct injection light diesel engine. Then described the development of a foam ceramic exhaust particulate processor. 485Q diesel engine bench test shows that foam ceramic filter can reduce diesel particulate emissions above 50%. When the exhaust temperature exceeds 450 ~ 480 ℃, the particles have been deposited on the filter can be self-combustion, the filter regeneration. In the diesel to add a small amount of some metal organics, regeneration temperature can be reduced.
