What Causes the Engine Warning Light to Illuminate When the Car Is Not Started?
1 Answers
When the car is not started, the engine warning light is on because the vehicle is performing a self-check, indicating that the engine is not yet operational. 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, creating expanding gases that push the pistons to perform work. Internal combustion engines typically transform chemical energy into mechanical energy. Methods for maintaining the engine include: 1. Regularly changing the oil and oil filter; 2. Using lubricants of appropriate quality grades; 3. Periodically cleaning the radiator; 4. Regularly replacing the air filter, oil filter, and fuel filter; 5. Ensuring good ventilation in the crankcase and cleaning it regularly; 6. Regularly cleaning the fuel system.
