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

Abstract

PURPOSE: To improve efficiency of a single point electronic injection system by providing a means to synchroize injection starting timing of a fuel injection valve every other air inlet stroke of air cylinders.
CONSTITUTION: In order to inject fuel during the time when it is delayed just by a settled crank angle taking a certain crank angle signal, such as top dead center signal, ignition timing signal as a reference, signal of an inhaled air amount detecting circuit 41 which has input the signals of hot-wire sensor of inhaled air measuring cylinder, pressure in the air inlet pipe, opening degree of throttle valve, movable burn angle, Karman vortex, swirler, etc., and signal from a crank angle detector 42 are input to a control circuit. This control circuit 17 compares this input signal with pre-memorized injection starting timing for deciding the injection starting timing. Output of this control circuit 17 is input through a delay circuit 43 to the base of a transistor 44, power of a battery 33 is supplied to a solenoid 22 of a fuel injection valve, which will be worked. Abnormal value at the time of transitional drive, and erroneous operation due to horary changes can be side-stepped.
