Stop/start control system for engine
A system is disclosed for automatically controlling the shutdown and restarting of a vehicle engine in order to conserve fuel at times when the vehicle would be otherwise stopped, with the engine running at idle speed and including in combination, an accumulator for computing and displaying the amount of fuel saved during shutdown. A central control comprised of an auto shutdown logic section and an auto start time delay logic section is connected to signal producing components on the vehicle and its engine and provides outputs to control engine shutdown and restart. The accumulating device utilizes an idle fuel flow reference with a clock input to compute the amount of fuel saved, which is indicated on the attached display. The logic functions of the accumulator are accomplished by a programmed microprocessor.
