FUEL SYSTEM


  1. CONSTRUCTION


    1. A 1-hole type high pressure slit nozzle fuel injector assembly (for direct injection), which has 1 injection hole shaped like a slit, is used.

    2. The use of this fuel injector assembly (for direct injection) causes the fuel to become highly atomized and spread over a wide fan-shaped area when it is injected into the combustion chamber. By injecting the fuel into the tumble flow in the cylinder, fuel injection dissipation performance is improved to achieve a homogeneous air-fuel mixture, high performance and high engine output.

    3. An O-ring and backup ring* are used in the fuel injector assembly (for direct injection). As a result, the transmission of operation noise from the fuel injector assembly (for direct injection) is reduced to enhance 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.
