Abstract

PURPOSE: To control an amount of fuel injection in constant without depending on a supplying voltage signal by a method wherein a means to control the amount of fuel injection at a constant value by comparing a current, flowing through a solenoid coil for a solenoid valve for feeding the fuel, with a standard signal is provided in series with the solenoid coil for the said solenoid valve.
CONSTITUTION: A current control signal 1 is converted into a constant current by a constant current source 10 and a constant voltage signal made by a resistor 16 is input into an amplifier 11, thus, a standard control signal 3 is obtained. On the other hand, a constant current controlling circuit, consisting of a comparator 12, a transistor 13 and resistors 20W22, is operated so that a load controlling signal 4 made by the resistor 22 becomes equal to the standard controlling signal 3 all the times. Accordingly, the standard controlling signal 3 is constant due to the constant current source 10, therefore, the load controlling signal becomes also constant, thereby, a collector current of the transistor 13, that means a current flowing through a solenoid coil 14 of a solenoid valve for feeding fuel for an internal-combustion engine, becomes constant without depending on a supplying voltage signal 2.
