<p>A multi-channel, sequentially timed fuel injection system for an internal combustion spark ignited engine employs a solenoid actuated injector valve for each cylinder controlled by the outputs of separate variable width pulse generators. The pulse generators each employ a resistance-capacitance discharge timing circuit and a single thermistor, common to all the generators, sensitive to engine temperature is connected to the RC circuits of the generators in a first circuit configuration during starting of the engine which provides a wide range of fuel delivery rates for starting and in a second circuit configuration during normal operation in which the various RC circuits are isolated from one another so that interaction. of the variable width pulse generators does not occur as a result of the common thermistor connection during normal engine operation.</p> |
