Abstract

1292937 Fuel injection systems BENDIX CORP May 28 1971 [16 June 1970] 17879/71 Addition to 1292771 Heading G1N In an I.C. engine fuel injection control system according to the parent Specification, the cold start circuit 100 is modified in that, after the single starting pulse at 102 is terminated, the high voltage at the collector of transistor 116 is applied to the base of transistor 104 to prevent faulty triggering, e.g. due to noise, of the circuit 100.
