What does 50cc mean?

[DeAnnie]

50cc refers to the engine displacement of 50 milliliters or 50 cubic centimeters. The maintenance methods for car engines are as follows: 1. Regularly change the oil and oil filter: The quality of any grade of lubricating oil will change during use. To avoid malfunctions, the oil should be changed regularly according to usage conditions, and the oil level should be moderate (generally up to the upper limit of the oil dipstick). 2. Regularly clean the radiator: Rust and scale can restrict the flow of coolant in the cooling system, reducing heat dissipation and causing the engine to overheat, even leading to engine damage. Therefore, the radiator should be cleaned regularly to remove rust and scale. 3. Regularly clean the crankcase: During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. Hence, the crankcase should be cleaned regularly to maintain the cleanliness of the engine interior.
