What does a high compression ratio in a car mean?
1 Answers
Car compression ratio refers to the vehicle having greater power, less emissions, and requiring higher octane gasoline. The compression ratio is the ratio of the maximum volume of the cylinder at bottom dead center to the minimum volume at top dead center during the compression stroke of the car. The function of the engine is to convert the thermal energy of gasoline or diesel into mechanical energy by expanding the gas after combustion in a sealed cylinder, thereby pushing the piston to perform work. The maintenance methods for the engine include: 1. Regularly changing the oil and oil filter; 2. Using lubricating oil of appropriate quality grade; 3. Regularly 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. Regularly cleaning the fuel system.
