SFI SYSTEM


  1. SYSTEM CONTROL


    1. The ECM performs integrated control to optimally adjust the throttle valve opening angle in accordance with the engine torque command signal from the hybrid vehicle control ECU, achieving smooth driving in any speed range.

    2. The throttle body assembly incorporates throttle valve opening angle control (nonlinear control) and Idle Speed Control (ISC).

    3. Cooperative control with the powertrain allows for excellent operability and driving comfort.

      Throttle Valve Opening Angle Control The throttle valve opening angle is controlled to generate engine output in accordance with the vehicle driving conditions and the engine torque command signal from the hybrid vehicle control ECU.
      Idle Speed Control Controls fast idle speed in accordance with the engine coolant temperature and controls idle speed after the engine has warmed up. Also, controls idle speed using the throttle opening angle in accordance with engine accessory load.
