1. A system for controlling the flow of air entering the intake manifold of a multicylinder variable displacement internal combustion engine installed in a vehicle having a manually operable accelerator control, said system comprising:

  • a position sensor for determining the operating position of the accelerator control and for generating an accelerator control position signal indicating such position;

    an engine speed sensor for determining the speed of the engine and for generating an engine speed signal indicating such speed;

    engine cylinder operator means for deactivating and reactivating at least some of said cylinders;

    an electronically controlled throttle valve positioned in the intake manifold of the engine, so as to control the amount of air entering the engine cylinders; and

    a processor connected with said cylinder operator means and with said throttle valve, with said processor comprising;

    means for receiving said pedal position and engine speed signals;

    means for selecting an operating position for the throttle valve, based on the values of the accelerator control position and engine speed signals, as well as upon the effective displacement of the engine.
