1 Answers
Engine oil classification standards: 1. AB series: Gasoline and light-duty diesel engine oils; 2. C series: Catalyst-compatible engine oils; 3. E series: Heavy-duty diesel engine oils. The functions of engine oil are: 1. To alleviate friction and high temperatures; 2. To cool and reduce temperature; 3. To clean and purify; 4. To dampen vibrations and cushion impacts; 5. To prevent rust and corrosion. Engine oil, also known as engine lubricant, includes: 1. Base oil: The main component of lubricating oil, determining its basic properties; 2. Additives: To compensate for and improve the shortcomings of base oil performance. The effects of using inferior engine oil are: 1. Degrading the quality of the oil, reducing its performance; 2. Damaging the lubrication of precision parts in fuel pumps and injectors; 3. Decreasing the power output of the generator set; 4. Affecting the combustion efficiency of the engine.
