燃油稀释对柴油机油摩擦学性能的影响
|
摘要
选用SRV~?4型摩擦磨损试验机为试验平台,以OEM发动机缸套-活塞环截取件为摩擦副试验件,模拟OEM发动机800h耐久性试验缸套磨损深度,并对不同品牌润滑油品及不同比例燃油稀释后的油品进行摩擦学性能研究。结果表明:燃油稀释对不同配方体系的柴油机油的摩擦学性能有显著影响。
Taking the SRV~? 4 type friction and wear test machine as the test platform,and the cylinder-piston ring intercepting part was used as the friction pair,and the cylinder wear depth of OEM engine for 800 hours durability test of OEM engine was simulated,and the tribological properties of different brands of lubricating oils and oils diluted by different proportions were studied.The results show that fuel dilution has a significant effect on the tribological properties of diesel engine oil with different formulations.
