What Does It Mean When a Car Indicates an Engine Fault?
1 Answers
When a car indicates an engine fault, it means there is a problem with the engine. The engine's function 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 pistons. Possible causes of engine faults include: Poor-quality gasoline, leading to incomplete combustion of the air-fuel mixture in the cylinder. Carbon deposits on the piston top, causing poor atomization and incomplete combustion. Excessive mileage, weakening the performance of the spark plugs. Advanced vehicle age, with mechanical wear leading to poor engine operation and inefficient combustion or ignition. Malfunctions in certain sensors or the engine control unit (ECU). If the fault light is on but the engine runs smoothly or with only slight vibration, the owner can continue using the vehicle normally. However, it is advisable to visit a repair shop at the earliest convenience to use a diagnostic scanner to read the fault codes and perform repairs based on the code definitions. Engine maintenance methods: Regularly change the engine oil and oil filter; use lubricants of appropriate quality grades; periodically clean the radiator; regularly replace the air filter, oil filter, and fuel filter; maintain good crankcase ventilation with periodic cleaning; and clean the fuel system regularly.
