摘要： An engine rotation speed control system which comprises an actuator for prescribing the recovery position of a throttle valve, a recovery position sensor for detecting that the throttle valve is returned to the recovery position, an idle speed control unit for controlling the engine to a predetermined idling speed, and a negative pressure restricting unit for controlling the throttle actuator such that reduction in intake negative pressure to below a predetermined negative pressure is prevented. When the throttle valve returns to the recovery position with the engine speed in excess of an upper limit of the idling speed, the actuator is controlled by the negative pressure restricting unit. When the engine speed falls below the upper limit, the idle speed control unit is actuated. Upon engine starting, the actuator is set such that the opening degree of the throttle valve suitable for the engine starting is obtained before the starter starts operating.

摘要： A fuel supply device for an internal combustion engine having an intake manifold includes a throttle body defining therein an intake passage communicating at one end thereof with the intake manifold. A flow accelerating valve arranged in the intake passage upstream of a throttle valve cooperates with the wall surface of the intake passage to define a flow accelerating passage of a smaller flow area than the intake passage. The flow accelerating valve is angularly movable in response to a change in the intake fluid flow between a fully closed position in which the flow accelerating passage has a minimum flow area and a fully open position in which the flow accelerating passage has a maximum flow area, to thereby control the flow area of the flow accelerating passage. A fuel injector injects liquid fuel into the accelerated intake fluid flow passing through the flow accelerating passage.

摘要： A method of controlling the air-fuel ratio so as to be effectively maintained at a desired air-fuel ratio of .lambda.=1 is composed of a combination of an electronic map control for effecting the air-fuel ratio control on the basis of map data read out from a data map stored in ROM as air-fuel ratio control data in correspondence to various operation parameters of an engine and an O.sub.2 -feedback control for controlling the air-fuel ratio on the basis of oxygen quantity detected from the exhaust gas. Upon the occurrence of changes in the control quantity for a predetermined number of times in the course of the O.sub.2 -control, the latter is changed over to the map control. At that time point, a control quantity for the map control is corrected on the basis of a mean control quantity during the O.sub.2 -feedback control. Unless a significant variation takes place in the engine operating conditions, the map control is continued for a predetermined time and then changed over to the O.sub.2 -control. Upon the occurrence of a significant variation in the engine operating conditions, the map feedback control is immediately changed over to the O.sub.2 -control.
