摘要： The idling speed of an internal combustion engine is controlled by controlling the position of a control valve disposed in the intake system of the engine to control the amount of intake air fed to the engine. A desired idling speed is determined according to the operating condition of the engine and the control valve is moved to a temporary target position which is expected to be suitable to obtain the desired idling speed. Then feedback control is carried out to converge the actual idling speed to the desired idling speed. When the actual idling speed is finally equalized to the desired idling speed, the actual position of the control valve at that moment is detected and memorized to be adopted as the temporary target position for the same operating condition in later control of the idling speed.

摘要： The difference between the actual idling speed of an internal combustion engine and a desired idling speed determined according to the operating conditions of the engine is integrated and the opening angle of the throttle valve is controlled according to the integrated value to control the amount of the intake air, whereby the actual idling speed is equalized to the desired idling speed. When the actual idling speed becomes higher than a predetermined value, the idling speed control is interrupted with said integrating operation being continued and the throttle valve is positively closed.

The system comprises an electro-mechanical actuator having an electric motor and a push rod engaged with a throttle lever for maintaining the throttle valve to an open state, a speed sensor for detecting the speed of the engine, and an electronic control circuit. A detecting means is provided for producing a pulse train according to the number of the rotations of the electric motor. The electronic control circuit comprises a comparing circuit connected to the speed sensor, a level setting circuit for applying a standard level to the comparing circuit for comparing the output of the speed sensor with the standard level, a counter for counting the output of the detecting means, and a control circuit for producing a pair of output signals in dependency on the outputs of the comparing circuit and of the counter. Output signals of the control circuit are applied to a driving circuit for driving the electric motor for projecting or retracting the push rod, so that the throttle valve is opened or closed in dependency on the output signals of the speed sensor for controlling the engine speed to the standard level.

摘要： An engine includes a main intake passage having a throttle valve therein. A bypass passage branches off from the main intake passage upstream of the throttle valve and connects again to the main intake passage downstream of the throttle valve. A flow control valve, actuated by a step motor, is arranged in the bypass passage. When the speed difference between the desired idling speed and the actual idling speed is higher than 20 r.p.m., the step motor is rotated in a direction wherein the actual idling speed approaches the desired speed. Contrary to this, when the above-mentioned speed difference is lower than 20 r.p.m., the step motor remains stationary.

摘要： An engine includes a three way catalytic converter in its exhaust system, and a carburetor whose throttle valve has a normal and an idle up idling position, selected between by an idle up device. A device for weakening the air/fuel ratio of the mixture in the engine intake system only functions when no oxygen is detected in the engine exhaust system by an oxygen sensor. A means for supplying enough secondary air into the exhaust system upstream of the oxygen sensor to make the exhaust gases leaner than stoichiometric functions according to supply of a controlling vacuum. A first vacuum take out port is provided in the throat of the carburetor at a position downstream of the throttle valve when it is in the normal idling position and upstream of it when it is opened a little from the normal idling position. A second vacuum take out port is provided in the throat at a position downstream of the throttle valve when it is in the idle up idling position and upstream of it when it is opened a little from the idle up idling position. A vacuum switching system supplies vacuum from either the first or second take out port to the secondary air supplying means as controlling vacuum, according as idle up is being not performed, or is being performed, respectively.

摘要： An idle speed control system for controlling the idle speed of an internal combustion engine, to conserve fuel by allowing a lowered idle speed, whenever possible, as well as offering more than normal power when needed, is disclosed. This idle speed control system includes an actuator for moving a secondary idle stop member into operative position, having both a vacuum-operated section and a solenoid section for maintaining the actuator in operative position, regardless of the state of the vacuum-operated portion. The idle speed control system further includes a control circuit responsive to engine speed which applies an output signal to the vacuum-operated section of the actuator when engine speed falls below a predetermined minimum, maintains it for a predetermined period of time, momentarily removes it to determine if the engine is presently capable of idling above the predetermined minimum speed, and reapplies the output signal if engine speed then dips below the predetermined minimum speed. Once applied, the output signal is removed either by the timer function, or when engine speed increases above the predetermined maximum idle speed. The control circuit also provides a signal to the solenoid portion of the actuator, in response to predetermined major accessory loads which may be imposed upon the engine in a vehicle.
