Abstract
An electronic control system for controlling the duration of operation of repetitively activated equipment produces a control signal from input signals representing the values of parameters related to the duration of operation. Timing signals generated from repetitive signals produced by the equipment are digitally shifted through a delay line at a rate determined by the control signal to establish the duration of operation of the repetitively activated equipment. The equipment may include a plurality of repetitively activated mechanisms, such as fuel injectors, which are sequentially selected and activated for the specified duration of operation.
