The fatal flaw of the FA20 engine is oil burning. Below are specific details about the engine: Definition: 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. Brief Description: The engine block forms the skeleton of the engine and serves as the installation base for all its mechanisms and systems. It houses all the main components and accessories of the engine, both internally and externally, and withstands various loads. Therefore, the engine block must have sufficient strength and rigidity. The engine block assembly mainly consists of components such as the cylinder block, cylinder liner, cylinder head, and cylinder gasket.
