What does 12 cylinders mean?

[VanLily]

12 cylinders refers to a 12-cylinder car engine, which is essentially the parallel connection of two V6 engines. Below is relevant information about car engines: Introduction: 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. Expansion: The term engine can refer to both the power-generating 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 also originates from English, with its original meaning referring to "a mechanical device that generates power."
