    摘要: An ignition timing controlling system of an engine for controlling a fuel injection flow rate and the ignition timing on the basis of intake air flow rate and an engine rotational speed. The system controls the ignition timing to the maximum ignition advance angle when a throttle valve is fully closed and the fuel injection is stopped as in the course of deceleration, or the throttle valve is fully closed and the fuel injection is stopped after a predetermined times of ignition have been effected, and controls the ignition timing to the optimum ignition advance angle when, thereafter, the fuel injection has returned.

    摘要: A stepping motor is driven to control an opening area of an intake air flow rate control valve such that an engine rotational speed in a substantially full-close position of a throttle valve is brought into a target rotational speed range related to at least an engine coolant temperature. An intake air quantity into an engine and engine rotational speed are detected to determine a ratio of the intake air quantity to the engine rotational speed. Downward control to the intake air flow rate control valve is inhibited when a ratio of intake air quantity into an engine to the engine rotational speed is smaller than a predetermined reference.

    摘要: Intake air flow rate control means having a control valve and a stepping motor for driving the control valve is arranged in a passage other than a passage in which a throttle valve is disposed. In a fast idling control mode (when a coolant temperature is below 70.degree. C., for example) and a hot idling control mode (when the coolant temperature is above 70.degree. C., for example), the control valve is driven by the stepping motor to control an engine idling rotational speed. The numbers of steps of the stepping motor for given coolant temperatures, which are to be used in the fast idling control mode, are previously stored as tables ST1.about.ST3. A converted value ISTA of steps corresponding to a target rotational speed is calculated based on a predetermined conversion expression. An arithmetic operation is carried out such that the number of steps ISTEP, which was learnt in the previous hot idling control mode and stored in a permanently powered memory, is equal to the converted value ISTA. In the fast idling control mode, prior to the feedback control of the control valve, the number of steps of the stepping motor ST for the given coolant temperature is corrected based on the number of steps ISTEP stored in the memory. The stepping motor is controlled by the corrected number of steps ST1A.about.ST3A.

    摘要: An intake air flow rate control device comprises a bypass passage for bypassing a throttle valve arranged in an intake manifold, flow control valve arranged in the bypass passage and stepping motor for driving the flow control valve. When the throttle valve is substantially fully closed, the stepping motor is driven to control an opening area of the flow control valve so that an engine rotational speed is within a range of a target rotational speed for at least an engine coolant temperature. In the above-described control, a lower limit of a stepping position of the stepping motor is set to prevent the opening area from being reduced beyond a predetermined area in order to prevent engine stall.

    摘要: A stepping motor is driven such that a rotational speed of an engine falls within a range of a target rotational speed determined in accordance with at least an engine coolant temperature when a throttle valve is substantially fully closed, in order to control an opening area of an air flow rate control valve. In the control operation, a lower limit of the opening area of the control valve is set to prevent the opening area from being reduced beyond a predetermined area in order to prevent engine stall. A predetermined setting is stored in a predetermined area each time when a vehicle speed signal from a vehicle speed sensor is received and the predetermined setting is decremented under a predetermined condition. When the decremented setting reaches zero, a current lower limit is maintained.

    摘要: An engine has a main intake passage having a throttle valve therein. A bypass passage is branched off from the main intake passage located upstream of the throttle valve and is connected to the main intake passage located downstream of the throttle valve. A flow control valve, actuated by a stepper motor, is arranged in the bypass passage. When the idling speed of the engine is increased beyond a predetermined upper limit of the engine speed, the stepper motor is rotated in a rotating direction wherein the flow area of the flow control valve is reduced. Contrary to this, when the idling speed of the engine is reduced below a predetermined lower limit of the engine speed, the stepper motor is rotated in a direction wherein the flow area of the flow control valve is increased.

    摘要: A bypass path is provided parallel to an intake path portion provided with a throttle valve, and the sectional area of flow in the bypass path is controlled by a valve body displaced by a stepping motor. The step value of the stepping motor is stored in a first memory storage of an electronic control. A second memory storage can keep values irrespective of opening and closing an ignition switch and the step value is stored also in the second memory storage. Corrected step values are supplied to the first memory storage from the second memory storage, from read only memory, or from a value dependent on temperature in a manner which will not result in stalling of the engine due to momentary interruptions in the supply of electric power to the electronic control.
