How Often Should the Engine Be Cleaned?

[McHope]

Engine should be cleaned every 20,000 to 40,000 kilometers. The function of the engine is: to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, causing the gas to expand and push the piston to perform work. The effects of sludge on the engine surface are: 1. It reduces the heat dissipation capacity of the cylinder block, leading to excessively high oil temperature and a decrease in engine power; 2. It increases the flow resistance of the oil, reduces the oil flow rate, and affects the lubrication effect of the oil. The working principle of the engine is: 1. Mixing air and gasoline in a certain proportion to form a combustible mixture; 2. The intake stroke draws the mixture into the cylinder, where it is compressed, ignited, and burned to produce thermal energy; 3. The high-temperature and high-pressure gas acts on the top of the piston, pushing the piston to perform reciprocating linear motion, and the mechanical energy is output externally through the connecting rod, crankshaft, and flywheel mechanism.
