SFI SYSTEM


  1. FUNCTION


    1. The Dual VVT-i system is designed to control the intake and exhaust camshafts. This system effects coordinate control with the VALVEMATIC in order to provide valve timing that is optimally suited to the engine conditions. This improves torque in all the speed ranges as well as increasing fuel economy and reducing exhaust emissions.

    2. Because the Dual VVT-i of this engine effects coordinate control with the VALVEMATIC, it has a timing advance characteristic that differs from the conventional Dual VVT-i. For details, see VALVEMATIC CONTROL and VALVEMATIC ACTUATOR.
