FUEL SYSTEM


  1. CONSTRUCTION


    1. A high-pressure injector with multiple injection holes (6-hole type) in which the injection angle is optimized and fuel is highly atomized is used for the direct fuel injector assembly.

    2. Fuel that is highly atomized by the direct fuel injector assembly is injected into the combustion chamber and it follows a vertical swirl flow (tumble flow) in the cylinder to improve fuel injection dissipation performance and achieve a homogeneous air-fuel mixture, high performance and high engine output.

    3. An insulator is used in the area in which the injector comes in contact with the cylinder head sub-assembly, and a Teflon shaft seal is used to seal the injector against the combustion pressure in the cylinders. This reduces vibration and noise and enhances sealing performance.

    4. An O-ring and backup ring* are used in the direct fuel injector assembly. As a result, the transmission of operation noise from the direct fuel injector assembly is reduced to improve quietness and ensure fastener airtightness.

      Note

      *: The backup ring is installed to securely support the rubber O-ring, which is subjected to high pressures. Take care to install the backup ring in the correct direction at the correct installation position.
