Title:
CONTROLLER OF INTERNAL-COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS5853649
Kind Code:
A
Abstract:
PURPOSE: To prevent an internal-combustion engine from presenting a racing condition of its speed, by inserting a resistor between an output signal line of an opening sensor and a power source.
CONSTITUTION: A pull up resistor 51 is inserted between an output signal line L of an opening sensor 30 and a power source. When the output signal line L of the opening sensor 30 is disconnected, an input signal by the actual opening of a throttle valve to an integrator, constituting a driver unit 50, becomes an obtainable maximum value by action of the pull up resistor 51, as a result the driver unit 50 controls the throttle valve through an actuator to the most closed opening obtainable.
