What are the causes of engine cylinder deactivation?

[StJessica]

Engine cylinder deactivation is caused by: 1. Excessive wear gap in the engine cylinder liner and piston rings, improper closing of intake and exhaust valves, and cylinder pressure insufficiency due to leaking valve seals; 2. Poor fuel atomization caused by worn fuel injectors, leading to increased or decreased fuel quantity, or even failure to inject fuel; 3. Issues with the engine control unit (ECU). An engine is a machine capable of converting other forms of energy into mechanical energy, suitable for power generation devices. It is categorized by structural function into: 1. External combustion engines: Fuel burns outside the engine; 2. Internal combustion engines: Fuel burns inside the engine; 3. Gas turbines: Combustion produces high-pressure gas, which drives the turbine blades to rotate and output power.
