ABSTRACT:
A controlling and switching mechanism utilizing radiant energy to activate each radiant energy sensitive switching member for applying an energizing pulse to its associated fuel injector of an internal combustion engine; the mechanism using a beam of radiation for each switching member, and having means for optionally varying the relative position of each beam striking its associated member in timed relationship with the operating engine shaft. The duration of an energizing pulse, in degrees of engine shaft rotation, is a function of that part of the switching member illuminated by the beam of radiant energy; the switching members being of sufficient magnitude along at least one dimension so that different parts of each switching member can be exposed to its associated recurring beam of radiant energy.
