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 having at least one element disposed between a revolving or recurring beam of said radiant energy and said switching member which controls the actuating means of its associated fuel injector; said element having an aperture and shutter therein for each switching member so that each aperture and shutter will be in a similar relative position with their associated switching member. The mechanism has means for exposing part of said member to said radiant energy by means of the associated aperture and shutter; the duration of an energizing pulse, in degrees of engine shaft rotation, is a function of the position of that part of the switching member exposed to the radiant energy.
