This is accomplished by enabling combustion of an ultra-lean mixture under many operating conditions. Direct injection is also designed to allow higher compression ratios, delivering higher performance with lower fuel consumption. Currently, direct injection gasoline engines are being deployed throughout the world in passenger cars. Mitsubishi GDI Mitsubishi Motors is aiming to achieve both low fuel consumption and high output. MMC is a world forerunner in the development of direct cylinder injection gasoline engines, known as GDI, which were first introduced in the 1996 Galant . GDI supplies fu
