Fuel Injector
WARNING: This page is about a different variant/trim than selected.
- The MFI system employs top feed type fuel injectors.
- Each injector is installed in the fuel pipe in such a way that the injector is cooled by fuel.
- The features of this type of fuel injector are as follows:
- High heat resistance
- Low driving noise
- Easy to service
- Small size
- The injector injects fuel according to the valve open signal from the ECM. The needle valve is lifted by the solenoid, which is energized on arrival of the valve open signal.
- Since the injector's nozzle hole area, the lift of valve and the fuel pressure are kept constant, the amount of fuel injected is controlled only by varying the duration of the valve open signal from the ECM.
- The multi-hole nozzle makes it possible for the injector to produce fine fuel particles, which enhances the combustion efficiency and output performance of the engine.
