摘要: 为探究润滑油中灰分对汽油机颗粒捕集器(GPF)耐久特性以及碳烟再生性能的影响,基于 快速积灰法进行了台架试验、整车试验和断层扫描(CT),分析了发动机扭矩、排气系统背压、灰分 质量、排放效果以及 CT 剖面图等多项数据。结果表明:润滑油灰分等级越高,产生的灰分越多, 被 捕集到 GPF 内的灰分比例也越大;积累在 GPF 中的灰分会导致发动机的性能下降,但气体排放得到 优化;少量灰分可提高碳烟再生速度,但灰分过多或无灰都会使再生速度降低。

Abstract: Bench and vehicle tests and a computed tomography (CT) scan were carried out to investigate the influences of ash contents in lubricants on the durability and soot regeneration of gasoline particulate filter (GPF) with the rapid ash accumulation method. It was analyzed that the data obtained from the tests including engine torque, exhaust system back pressure, ash mass, emission effects, and CT profiles. The results show that the higher the ash level in the lubricants, the more ash is produced and the greater arrested proportion of GPF is obtained; the accumulated ash in the GPF can cause the degradation of the engine performance, but the gas emission can be optimized; a small amount of ash can increase soot regeneration speed, but too much or no ash will reduce its regeneration speed.

Key words: gasoline particulate filter (GPF) , lubricant, durability, soot regeneration, ash
