<p>A cold start auxiliary circuit for use in conjunction with an electronically controlled fuel supply system is disclosed herein. The cold start auxiliary circuit is comprised of a first circuit which receives and stores a signal indicative of instantaneous engine temperature during the time period when the electrical system energization of the vehicle is substantially stable and a second circuit which is energized by the vehicle electrical system and is triggered upon the initiation of engine cranking but which is otherwise not influenced by the electrical energization fluctuation incident to the cranking cycle. The cold start circuit produces an output signal which is substantially proportional to the difference between the sensed engine temperature and an established reference upon triggering of the second circuit.</p> |
