Is Engine Lubricant Necessary?
1 Answers
Engine lubricant is necessary. It serves functions such as lubrication, cleaning, cooling, and rust prevention. If an engine lacks lubrication, friction components can easily seize, causing irreversible damage to the engine. The function of an engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, which expands the gas and drives the piston to perform work. Methods for maintaining an engine include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning scale from the radiator; 4. Regularly removing carbon deposits from the engine; 5. Regularly replacing the three filters in the car; 6. Maintaining a reasonable engine speed.
