ABSTRACT:
A timing signal generator operates in response to engine position sensors to generate pulse signals in sequence, the leading edge of each of said pulses essentially coinciding with the valve opening time of an associated one of the cylinders of an internal combustion engine. The outputs of the timing signal generator are fed to a control signal generator which generates a series of pulses, one for each of the engine cylinders, the leading edges of these pulses each approximately coinciding with the leading edge of a corresponding one of the timing signal generator outputs. The pulse widths of the outputs of the control signal generator, which are controlled in accordance with various engine parameters, are indicative of engine fuel requirements for optimum engine efficiency and/or minimum emission of pollutants. The pulse signal outputs of the control signal generator are each used to control a respective one of the fuel injectors for the engine to provide fuel to each of the cylinders at the proper time and for a time duration which is precisely in accordance with engine requirements.
