Mitsubishi engines employ highly efficient combustion methods such as rolling combustion and optimal fuel injection. This combustion method ensures complete combustion of fuel, improving combustion efficiency and thus enhancing engine power output and fuel economy. Simultaneously, by strengthening the rigidity of the cylinder block and crankshaft, and using vibration-damping resin materials in some components, engine noise is minimized.
For example, the Mitsubishi S12H engine excels in this regard; its efficient combustion method and noise reduction technology provide a more comfortable driving environment. Furthermore, the efficient combustion method allows Mitsubishi engines to meet Euro 3 and Euro 4 emission standards, complying with modern environmental requirements.
