Abstract

A controller system is provided for controlling the power boost operation of an internal combustion engine by increasing fuelling, the controller means comprising a fuel controller for controlling the rate of fuel supplied to the engine and for supplying an increased rate of fuel in response to a power boost demand signal. The controller system further includes a first timer for measuring a first time period during which the power boost signal is supplied to the fuel controller, a comparator for supplying a prevent boost signal when the first time period exceeds a maximum boost time period, and a second timer for preventing the fuel controller from supplying the increased rate of fuel for a second time period in response to the prevent boost signal.
