Abstract

1323629 Fuel injection systems BENDIX CORP 16 Aug 1971 [21 Sept 1970] 38383/71 Heading G1N [Also in Division H3] In an I. C. engine intermittent fuel injection system, a diode arrangement is connected to the electro-magnetic coil of a fuel injection valve; the diode arrangement being reverse biased when the coil is energized and being conducting following termination of the energization to thereby dissipate the energy stored in the coil. As shown in Fig. 3 two groups of electromagnetic valves 204, 206 are sequentially energized by pulses provided at 126 from a computing circuit, Fig. 2 (not shown). The computing circuit is of the type which provides two closely spaced pulses, the first pulse being triggered in synchronism with engine rotation and having a duration dependent upon intake manifold pressure, and the second pulse having a duration dependent upon that of the first pulse and upon engine temperature. A bi-stable circuit 208 provides sequential operation of the valve groups, via respective amplifiers 210, 211. The diode arrangement consists of respective diodes 212, 214 for each valve group having their anodes coupled and connected to the anode of a zener diode 216 whose cathode is grounded. The diodes 212, 214 are each reverse biased when its respective valve group is energized, but upon termination conduct the induced current in the coils to the zener diode which is arranged to be reverse biased beyond its voltage breakdown point by the induced current. A separate zener diode may be provided for each diode 212, 214.
