FUEL SYSTEM


  1. CONSTRUCTION


    1. High-pressure, single slit-nozzle type fuel injector assemblies are used in conjunction with the adoption of the Direct injection 4-stroke gasoline engine Superior version (D-4S) system.

    2. The use of this direct fuel injector assembly causes the fuel to become highly atomized and spread over a wide fan-shaped area. At the same time, the fuel is mixed with a large amount of air and injected into the combustion chamber. As a result, fuel injection dissipation performance is improved to achieve a homogeneous air-fuel mixture, high performance and high engine output.

    3. A fuel injector seal is used for the cylinder internal pressure sealant and an insulator is used at the cylinder head sub-assembly contact area to reduce vibration and noise and improve 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.
