摘要
本文通过对日产 4 D1 0 5— 5柴油机各气缸压力的瞬态采集 ,较详细研究了车用柴油机冷起动过程 .分析了柴油机燃烧不稳定对冷起动过程的影响 .结果表明 :柴油机在低温状态下尤其在边界状态下各气缸着火状态有较大差异 ,部分气缸出现失火 ,造成冷起动过程极不稳定 。
This paper makes a research on the cold start of diesel engine for automobile,by way of transient state acquisition of pressure in each cylinder of the Nissan 4D105 5 diesel engine.The effect of the instability of ignition on the cold start is analyzed.Results show that,among cylinders,there is a quite significant difference in ignition at the low temperature,especially under the borderline state.Some cylinders may appear to have loss inignition,causing instability of the cold start,which leads to the difficulty of cold start of diesel engine for automobile.
