How often should engine cleaning and maintenance be performed?

[ArianaLee]

Engine cleaning and maintenance should be performed every 20,000 kilometers. Related introduction: 1. Overview: An engine (Engine) is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. 2. Expansion: Engines can refer to both power generation devices and the entire machine including the power unit (e.g., gasoline engines, aircraft engines). The engine was first developed in the UK, so the concept of an engine also originates from English, with its original meaning referring to "a mechanical device that generates power."
