Abstract
An electronic fuel control device is used to activate a fuel system carried on board a motor vehicle independently of a computer system carried on board the vehicle. The fuel control device embodies an electrical circuit to create an output of a series of pulses of electrical energy. Electrical power is carried to the electrical circuit by electrical supply conducting apparatus. The pulses of electrical energy are transported from the electrical circuit to the fuel injecting system by electrical pulse conducting apparatus connected to the fuel injecting system.
