What causes the engine warning light to come on?

[ClaraDella]

The reasons for the engine warning light coming on are: 1. Poor combustion state; 2. Engine knocking; 3. Poor fuel quality or unclean internal engine cylinders. It is recommended to promptly check the working condition of the engine and seek professional repair at a specialized maintenance shop to avoid causing more significant malfunctions. An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. The working characteristic of an engine is that combustion generates high-pressure gas, which is used to push the turbine blades of the gas turbine to rotate, thereby outputting power.
