The reasons for the engine fault light coming on are: 1. Irregular maintenance; 2. Deteriorated engine oil; 3. Clogged air filter; 4. Dirty intake pipes; 5. Excessive sludge in the crankcase; 6. Fuel system requires maintenance; 7. Rust and scale in the radiator. An engine is a machine that converts one form of energy into mechanical energy. It can refer to both the power-generating device and the entire machine including the power unit. Types of engines include internal combustion engines, external combustion engines, electric motors, etc. Common gasoline and diesel engines are internal combustion engines that convert the chemical energy of fuel into the mechanical energy of piston movement to generate power.
