如何让发动机润滑系统实现高效运营,可能困扰着每一位工程机械用户,提高润滑系统的专业水准主要体现在两个方面:第一,选择高性能产品;第二,提高维护保养水平。如何选择高性能润滑油品我国目前市场上销售的发动润滑油的规格、牌号有两个代码:美国石油学会(API)质量等级和美国汽车工程师协会(SAE)黏度等级。API代表润滑油质量等级,分汽油机油和柴油机油,S代表汽油机油:SJ,SL,SM,SN/GF-5;C代表柴油机
How to make the engine lubrication system to achieve efficient operation may plague every construction machinery users to improve the professionalism of the lubrication system is mainly reflected in two aspects: first, select high-performance products; second, improve the level of maintenance. How to choose high-performance lubricants China currently on the market launched the specification of lubricants, grades have two codes: American Petroleum Institute (API) quality level and the American Society of Automotive Engineers (SAE) viscosity grade. API on behalf of the quality of lubricants, gasoline engine oil and diesel engine oil, S on behalf of the gasoline engine oil: SJ, SL, SM, SN / GF-5; C on behalf of the diesel engine
