Abstract
PURPOSE: To maintain the mixture ratio at a prescribed value by operating an driving output pulse width of a fuel injection valve, by means of an output from a throttle valve opening detector and an output from a heat ray type air flowmeter, in case of an electronic control fuel injection device.
CONSTITUTION: A control circuit 11 connected to a heat ray 9 acts as a heat ray type air flowmeter signal 1 in accordance with a degree of opening of an throttle valve 6, and is converted together with an output of a transmitter 10 of a degree of opening of a throttle valve, by means of A/D converters 2, 2' in a control unit 12, and subsequently fed in a read-conversion mechanism 3 which converts a digital output voltage to an air flow. Being converted here to an air flow Q, this flow is jetted from a fuel injection valve 5. After the fuel injection pulse width is calculated in an output pulse width operation system 4 for driving a fuel injection valve. Since the reading of heat ray output 1 is converted to the actual air flow Q by means of the output of a detector 10 of a degree of valve opening acting as a parameter, a mixture ratio may be maintained at a prescribed value without being influenced by a degree of opening of the valve.
