What are the factors that cause the engine fault light to illuminate?

[LaRachel]

Factors that cause the engine fault light to illuminate include: 1. Poor combustion state; 2. Engine knocking; 3. Poor fuel quality; 4. Carbon deposits inside the cylinders. An engine is a machine that converts other forms of energy into mechanical energy, originating in the UK. It can refer to both the power generation device and the entire machine including the power unit (such as gasoline engines, aircraft engines). Engine types include internal combustion engines (e.g., gasoline engines), external combustion engines (e.g., Stirling engines, steam engines), and electric motors. External combustion engines burn fuel outside the engine, invented by R. Stirling of Scotland, hence also known as Stirling engines.
