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 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.
摘要翻译： 控制空燃比以有效维持在λ= 1的期望空燃比的方法由用于基于地图数据进行空燃比控制的电子地图控制的组合 从存储在ROM中的数据图中读出，作为与发动机的各种操作参数相对应的空燃比控制数据，以及基于从废气检测的氧气量来控制空燃比的O2反馈控制。 在O2控制的过程中发生控制量改变预定次数时，将后者改变到地图控制。 在该时间点，基于在O2反馈控制期间的平均控制量来校正地图控制的控制量。 除非在发动机工作条件下发生显着变化，否则地图控制继续预定时间，然后转换到O2控制。 在发动机运行条件发生显着变化时，地图反馈控制立即转换到O2控制。
