Abstract: An improved method and apparatus is provided to control the rate at which fuel is supplied to an engine by a fuel pump. The fuel pump has an output pressure which varies with pump operating speed in accordance with different curves of a series of curves. In order to determine which curve of the series of curves is representative of the manner in which the fuel pump output varies with pump speed at one time, the fuel pump operating speed and output pressure are simultaneously sensed to determine a point on an initial curve. The fuel pump operating speed is subsequently varied in accordance with the initial curve to provide a desired variation in fuel pump output to the engine. The fuel pump operating speed and output pressure are periodically simultaneously sensed to determine if the fuel pump output still varies in accordance with the initial curve or has changed to a second curve of the series of curves.

Abstract: The duty factor of pulses controlling the time throughout which current flows through an ignition coil is increased or decreased depending upon whether the current through the ignition coil at the last ignition time was less than or greater than the desired amplitude required for ignition. A sample--and--hold circuit samples the output of a comparator comparing the actual current to the desired current at ignition time. If the comparator indicates that the actual current amplitude was less than the desired current amplitude, a first counter is set to count downwards. It counds down by one unit and then its count is transferred to another counter. When the count on the other counter reaches a predetermined count, the current through the ignition coil is initiated. The current is interrupted when either the next ignition timing signal or a signal signifying that the actual current through the ignition coil has reached the desired value is received, whichever is later.
