What Type of Engine Oil Can Reduce Noise?

[DelaneyAnn]

Each car engine's internal mechanical components have different designed manufacturing clearances. Using engine oil with the appropriate viscosity as required can effectively reduce noise. Below is a partial introduction to the functions of engine oil: 1. Lubrication and Wear Reduction: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing shells. To prevent excessive wear on parts, an oil film must be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. 2. Shock Absorption and Cushioning: When the pressure at the engine cylinder port rises sharply, it suddenly increases the load on the piston, piston rings, connecting rod, and crankshaft bearings. This load is transmitted and lubricated through the bearings, cushioning the impact load.
