Direct injection classification

Direct Injection (GDI) also called called spark ignition direct injection technology (SIDI) and Fuel Stratified Injection (FSI), which is widely used in today's two-stroke or four-stroke gasoline engine. Different from the fuel injection nozzle is placed on the practice of the intake manifold, the direct injection nozzle is placed in the cylinder, the high-pressure fuel pump through the fuel injection into the combustion precise indoor, more atomizing meticulous, mixed with air more evenly, ensuring a more smooth and efficient fuel combustion. Direct injection to achieve a ratio of more precise control of the mixture, eliminate shortcomings-cylinder direct injection Evo 4G63 rods.

At the same time, the position of the nozzle, spray pattern, intake air and inlet pressure, as well as the design of the combustion chamber can change different mix proportions of oil and gas, in order to achieve uniform combustion or stratified combustion. Direct injection combustion in stratified on the basis of achieving a lean-burn technology also in improving fuel efficiency to ensure high output while reducing fuel consumption. In environmental protection, low-emission, high-power era, the traditional direct-injection gasoline engine technology represents an important technological innovations. GDI engine compared to those of ordinary manifold fuel injection engine and carburetor engines, cancel the throttle design, so GDI engine is not throttling losses, but also reduces pumping losses, greatly improving the intake efficiency.

Engine speed by the engine control unit / launch management system (EMS) to adjust the fuel injection quantity and injection time to achieve, rather than indirectly by controlling the intake air throttle controls engine Mitsubishi 4G63 rods speed. To achieve this function requires EMS has considerable storage and computing power, ignition timing and engine speed is controlled by a very precise calculations to ensure that there is good power and driving performance.
