Abstract

1435098 Fuel injection control systems LUCAS ELECTRICAL CO Ltd 30 April 1973 [13 May 1972] 22781/72 Heading G3N [Also in Divisions Fl and H3] A fuel supply system for an I.C. engine includes a throttle valve having an angularly movable spindle, a digital encoder for producing a digital output corresponding to the angular position of the spindle, and an electronic fuel supply control unit responsive to the encoder output for controlling the rate at which fuel is supplied via injection nozzles to the engine. The encoder comprises an arm 25 mounted for rotation with the spindle 23 and having a plurality of fixed contacts 26 mounted thereon. One of these contacts is permanently in contact with an arcuate conductive area 27a of a code plate 27 and the others move over arcuate rows of alternately conductive and non-conductive areas on the plate 27 the conductive areas of each row being connected to a terminal 27b. For any spindle position, a predetermined number of the terminals 27b will be connected to the arcuate area 27a. The code employed is preferably Gray code.
