What is the internal structure of a car?

[McDeclan]

An automobile generally consists of four basic components: the engine, chassis, body, and electrical equipment. The following is an introduction to engine-related content: 1. Energy conversion: An engine is a machine capable of converting 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. Device: The term 'engine' can refer to both the power generation device 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 the engine originates from English, with its original meaning referring to 'a mechanical device that generates power.'
