FUEL SYSTEM


  1. CONSTRUCTION


    1. Double slit-nozzle type injectors, which have 2 slit-shaped injection orifices, are used as fuel injectors for direct injection.

    2. Each injector, based on signals from the ECM, measures the flow of high-pressure fuel. The fuel is injected as a fine-atomized mist in a fan shaped pattern, directly to the combustion chamber, via a slit type nozzle.

    3. An insulator is used in the area in which the injector comes in contact with the cylinder head, and a Teflon shaft seal is used to seal the injector against the combustion pressure in the cylinders. This is conducted in order to reduce vibration and noise and to enhance sealing performance.

    4. Each nozzle tip is coated to reduce the adhesion of deposits.

    5. The injectors are actuated by the EDU using high-voltage and a constant-current control based on instructions from the ECM. This control allows the injectors to inject high-pressure fuel in a short time frame.
