  • Electrical Control Of Air Or Fuel Supplied To Internal-Combustion Engine (AREA)

Abstract

PURPOSE: To precisely control an engine by increasing the quantity of fuel supply when a throttle valve opens rapidly and performing its increase from the beginning depending upon the degree of acceleration.
CONSTITUTION: The number of engine revolution detection circuit 5 generates out- put corresponding to engine revolution and controls the fuel increasing circuit 6 to perform increase in accordance with the number of machine revolutions. The increase circuit 6 corrects the signals representing the increase which passes through the differential amplification circuit 3 by the output of the number of machine revolutions detection circuit 5 and supplies them to the fuel increasing circuit 7 of an electronical controlled fuel injector control unit. It then commands the fuel required for generating the rich mixture which is required at sudden acceleration to the fuel injector from the fuel increasing circuit 7.
