Abstract : Electrical signals from a vehicle distributor are processed by a pulse generating circuit. Generated pulses are integrated to form an analog signal which is linearly proportional to engine speed. The analog signal is algebraically summed with an analog signal derived from a vehicle accelerator pedal. A resultant summed signal is fed to a voltage controlled one-shot which produces output pulses having a constant amplitude with a frequency proportional to the engine speed. The width of each pulse is inversely proportional to the engine speed. The integral or the area under the pulses derived from the voltage controlled one-shot remains constant, the pulses being fed to a fuel injector that injects fuel into a vehicle carburetor in a manner maintaining a constant engine speed regardless of load.
