ABSTRACT:
In an engine control system, particularly for fuel injection, the frequency of a variable frequency clock is compared with an output signal from a memory device and the difference used to control an engine function. The frequency of the clock is determined by the collector current of the transistor having two variable resistors controlling its emitter and base currents respectively. This invention relates to engine control systems and is particularly, but not exclusively, intended for use in fuel injection systems for engines.
