We all know that engine lubricating oil is used in the engine, which can effectively reduce the friction between its internal components, so as to promote the good operation of the engine. But is the oil just lubricating? Of course not, so what else can it do?

cleaning effect

The cleaning effect refers to cleaning the charcoal, oil and other stains produced by combustion, or decomposing the stains in the oil, or removing the stains by using an oil stain filter. Engine oil cleans the engine, removes impurities left in the filter, and protects metal surfaces from the acids formed during combustion. At the same time, the engine oil can also take away combustion residues, combustion products or oxidation products of lubricating oil, and quickly settle to the bottom of the oil pan. Therefore, the oil looks like a black and dirty thing, and its quality cannot be judged only by naked eyes.

cooling effect

Cooling effect, that is, the effect of cooling the engine. Engine oil assists the cooling system by removing the heat generated by the pistons. Gasoline is injected from the opposite side when cooling the piston. Therefore, engine oil must have good cooling properties and be able to withstand high temperatures.

Anti-rust effect

The function of anti-rust is to prevent rust, just like oiling swords and other things, the metal parts in the engine should also prevent rust. All these are due to another important feature of lubricating oil, waterproof, so that engine oil can effectively prevent rust.

Anti-oxidize effect

Engine oil fully protects all parts of the engine. The high temperature generated by the engine will accelerate the oxidation of the engine oil. Therefore, the engine oil must have excellent oxidation resistance to ensure that the engine oil can maintain a normal viscosity within a certain oil change interval and protect all parts of the engine to work normally.

buffering effect

The engine oil can withstand a certain impact load transmitted by the bearing and play a buffer role, thereby eliminating the impact load between the bearing and other parts of the engine to a certain extent.

Sealing effect

The last is the sealing function. The sealing function of the engine oil is to seal the piston and the cylinder of the engine. This sealing degree is very important, which can effectively prevent the cylinder from blowing, ensure the output of the effective power of the engine, and improve the power of the vehicle. That is, the engine oil is dripped into the gap between the piston and the cylinder to maintain the cylinder pressure function.
