What does engine assembly replacement mean?

[DeAbel]

It refers to the replacement of the engine. The engine assembly, also known as the engine, has the following specific meanings: 1. It is a machine for energy conversion: a machine capable of converting one form of energy into another more useful form, typically converting chemical energy into mechanical energy; 2. It includes power devices: those that convert electrical energy into mechanical energy are called electric motors, and sometimes the term applies both to power-generating devices and the entire machine including power devices; 3. Specific examples: such as gasoline engines, aircraft engines; 4. Requires fuel: regardless of the type of engine, its basic premise is to generate power by burning some kind of fuel. Therefore, electric motors that use electricity as an energy source do not fall under the category of engines.
