Is the Mitsubishi 4a92 Engine Really That Outdated and Fuel-Consuming?

[DeRicardo]

The Mitsubishi 4a92 engine is not particularly fuel-consuming; it largely depends on road conditions and vehicle usage. Below is relevant information about the engine: 1. Introduction: An engine is a machine capable of converting non-mechanical energy into mechanical energy. 2. Classification: Includes internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, among others. 3. External Combustion Engine: An external combustion engine means the fuel burns outside the engine. 4. Internal Combustion Engine: An internal combustion engine, or reciprocating piston engine, differs significantly from external combustion engines in that the fuel burns inside it. There is a wide variety of internal combustion engines, with common gasoline and diesel engines being typical examples.
