What are the reasons for the car engine light to come on?

[BraydenMarie]

The reasons for the car engine light to come on include: 1. Poor gasoline quality leading to incomplete combustion of the air-fuel mixture in the cylinder, resulting in carbon deposits; 2. Carbon deposits in the intake tract and piston top causing poor atomization and incomplete combustion; 3. Excessive mileage of the engine, weakening the working characteristics of the spark plugs; 4. Faulty ignition coils causing poor ignition and incomplete combustion; 5. Excessive vehicle age leading to mechanical aging, poor engine condition, and suboptimal combustion and ignition. The engine is the device that provides power to the car, determining its power, fuel economy, stability, and environmental friendliness. Its types include diesel engines, gasoline engines, electric vehicle motors, and hybrid engines.
