润滑油添加剂对汽油机低速早燃影响的研究进展

RESEARCH PROGRESS ON INFLUENCE OF LUBRICATING OIL ADDITIVES ON LOW SPEED PRE-IGNITION OF GASOLINE ENGINE

汽油机低速早燃的发生严重制约汽油机燃烧效率,在影响低速早燃的诸多因素中,润滑油添加剂对低速早燃的发生起着至关重要的作用。详细分析了含钙、锌、钼、镁、钠等润滑油添加剂对汽油机低速早燃的影响,并介绍汽油机低速早燃的发生机理。针对减少汽油机低速早燃发生频次提出了改进润滑油添加剂组分及配方的建议。

The low-speed pre-ignition severely restricts the combustion efficiency of gasoline engines.Among factors affecting the low-speed pre-ignition,lubricant additives play a vital role.The effects of the additives containing calcium,zinc,molybdenum,magnesium,and sodium on low-speed pre-ignition of engines and the mechanisms are reviewed.In order to reduce the frequency of low-speed pre-ignition,optimization measures in composition and formula of lubricant additives are suggested.
