摘要： An engine comprising 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 step motor, is arranged in the bypass passage. The step motor comprises a rotor and a stator having exciting coils. When the engine is operating in an idling state, the exciting coils are excited for rotating the step motor in a rotating direction wherein the engine speed approaches a desired idling speed. When the engine speed becomes equal to the desired engine speed, the exciting operation of the exciting coils is stopped.

摘要： An engine comprising 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 step motor, is arranged in the bypass passage. When the engine is operating in an idling state, the step motor is rotated at a first speed in a rotating direction wherein the engine speed approaches a desired engine speed. When the ignition switch is turned to the OFF position for stopping the engine, the step motor is rotated at a second speed which is lower than the first speed a little while after the flow control valve fully opens the bypass passage.

摘要： A spark-advance angle of an internal combustion engine is calculated based on at least one electrical signal which indicates an operating condition of the engine. The calculated spark-advance angle is compared with a lower limit of a required spark-advance angle, and then, if the calculated spark-advance angle is less than the lower limit, this calculated spark-advance angle is corrected so that it coincides with the lower limit.

摘要： A fuel injection control system for internal combustion engine comprises a fuel injection pump including a plunger slidably reciprocating in synchronism with rotation of the engine and a spill port establishing communication between a low pressure chamber and a pump chamber. An electronic control unit is responsive to engine operating conditions for the determination of fuel injection time period and controls the solenoid-operated valve to close the spill port in response to the requirement of fuel injection into the cylinder and open the same to terminate the fuel injection. The fuel injection control system further comprises a circuit including two fixed resistors and two adjusting resistors so that first and second voltage signals are developed at its terminals. The two adjusting resistors respectively determine the value of the voltage signals. The first voltage signal is regulated to correspond to the response time lag inherent in the solenoid valve and the second voltage signal is regulated to correspond to the error of the generation timing of the detection signal of a reference plunger position detector. The correction of fuel injection time period is made on the basis of the first and second voltage signals. pg,4

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.
