  • means for generating high- or low-power representative signals in response, respectively, to an acceleration command becoming greater or smaller than a predetermined value;

    a time constant electrical circuit responsive to said low-power representative signal for generating an output signal varying as a function of time; and

    a bistable device having a first input terminal responsive to said high-power representative signal for generating a cylinder activating signal to activate said at least first and second cylinders and a second input terminal responsive to said output signal from said time constant electrical circuit reaching a preset value for generating a cylinder deactivating signal to deactivate at least said second cylinder while allowing said at least first cylinder to remain activated.
