How often should an engine be serviced?

[VanJace]

An engine should be serviced every six months or every 5,000 kilometers. The maintenance methods for an engine include: 1. Regularly changing the oil and oil filter; 2. Using lubricating oil of the appropriate quality grade; 3. Periodically cleaning the radiator; 4. Regularly servicing the air filter, oil filter, and fuel filter; 5. Maintaining good ventilation in the crankcase and cleaning it regularly; 6. Periodically cleaning the fuel system. 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, causing the gas to expand and push the piston to perform work. The main components of an engine are: 1. The valve train; 2. The crankshaft and connecting rod mechanism; 3. The ignition system; 4. The cooling system; 5. The lubrication system; 6. The starting system; 7. The fuel supply system.
