Injector (MPI)
A fuel injector directly sprays fuel to the engine cylinders and the fuel amount is determined by the Engine Control Module (ECM). Since it injects the high-pressure fuel supplied by a high-pressure fuel pump directly to the combustion chamber, the intake air temperature will drop and the density of the fuel will increase during the suction process, which improves engine power. Direct injection and separate injection enhances fuel efficiency and engine power.
