SFI SYSTEM


  1. FUNCTION


    1. The ECM performs variable control to achieve the high pressure fuel pressure in accordance with the driving conditions. A system that only discharges the necessary fuel amount via the spill control valve control has achieved drive torque reduction and reduced noise.

    2. The ECM performs feedback control to achieve the desired value based on fuel pressure signals from the fuel pressure sensor installed for the fuel delivery pipe (for direct injection).
