摘要： A fuel control system for an automobile engine includes various sensors for detecting the running conditions of the engine, an injector or injectors for supplying fuel to the engine, and a control unit for reducing or cutting the amount of fuel to be supplied to the engine in response to the sensors at the time of deceleration and for controlling the injectors so that the amount of fuel to be supplied to the engine at the time of removal of deceleration is less than the normal amount corresponding to the running conditions of the engine. The control unit further operates so that the amount of reduction of the fuel supply is less in an engine equipped with an automatic transmission than in an engine equipped with a manual transmission. The control unit also operates so that the initial amount of fuel to be supplied to the engine at the time of removal of deceleration is less in the engine equipped with the manual transmission than in the engine equipped with the automatic transmission. In addition, the control unit can operate so that the rate of increase of fuel up to the normal amount after the removal of deceleration is less in the engine of the former type than in the engine of the latter type.

摘要： A system for controlling idling speed of an internal combustion engine in which a speed sensor senses rotational speed of the engine. A determinator is provided for determining whether the engine is in an idling state. An output adjustor adjusts engine output when the engine is determined to be in the idling state by the determinator. A memory stores a control variable of the output adjustor in the form of a characteristic in which engine output rises approximately in proportion to a difference between a predetermined target idling speed and an actual idling speed with engine speed serving as a parameter. A control acts responsive to outputs from the determinator and the speed sensor for obtaining from the memory a control variable corresponding to engine speed at idling, and for controlling the output adjustor on the basis of the control variable. A load detector detects whether an external load is connected with the engine in operational relation; and a control variable characteristic changer changes characteristic of the control variable from the memory responsive to output from the load detector.

摘要： A catalyst degradation determination apparatus having O.sub.2 sensors provided at the upstream and downstream of a catalyst, detects degradation of the catalyst by, during A/F ratio feed-back control since an engine has been started, comparing an integrated value of output values from the upstream O.sub.2 sensor with that of output values from the downstream O.sub.2 sensor. Upon starting integration of the output values from the respective O.sub.2 sensors, change of activated status of the catalyst is judged. If the status of the catalyst is approximately the same as a previous status, the integration is started with previous integrated values. On the other hand, if the status of the catalyst is different from the previous status, the previous integrated values are reset, and the integration of the output values from the respective O.sub.2 sensors is started from the beginning. This prevents erroneous catalyst degradation determination.

摘要： A fuel injection control system is designed to be commonly available to an engine with a manual transmission and an engine with an automatic transmission. The internal combustion engine has a fuel injection device for delivering different amounts of fuel to the engine according to engine operating conditions. The fuel injection control system causes the fuel injection device to make an increase in fuel amount when the engine operates in a specific zone of engine operating conditions defined by engine operating speeds and loads. When the engine operating condition remains in the specific zone, the control system makes the increase in fuel amount with a time delay from a time the engine operating condition changes into the specific zone. The specific zone, when the engine is equipped with an automatic transmission, is expanded toward a side of engine speeds higher than an engine speed by which an upper extreme engine speed of the specific zone is defined that when the engine operates in the expanded part of the specific range and at high elevations, the system intentionally causes an increase in fuel.

摘要： An engine speed control system causes an engine, equipped with an automatic transmission which shifts up according to predetermined shift schedules, to reduce its output at a predetermined engine speed so as to protect the engine by preventing the engine from being subjected to "over-revolution." The predetermined engine speed is changed according to engine operating conditions such as a decrease in engine temperature. Simultaneously, a shift-up vehicle speed, at which the automatic transmission shifts itself up, is decreased according to engine operating conditions and, more particularly, engine temperatures and throttle openings. As a result, an up-shift of the automatic transmission properly takes place, even when the vehicle travels at lower speeds.

摘要： In an automatic transmission control system, completion of gear-shifting is detected on the basis of both the rate of change in rotational speed of the output shaft of the torque converter and the rotational speed at which the output shaft of the torque converter is expected to rotate. That is, a rotational speed range within which the rotational speed of the output shaft of the torque converter is expected to fall upon completion of the gear-shifting is determined taking into account the rotational speed of the output shaft of the torque converter upon initiation of the gear-shifting and the gear ratio, and it is determined that the gear-shifting is completed when the rotational speed of the output shaft of the torque converter falls within the predetermined rotational speed range and the rate of change in rotational speed of the output shaft of the torque converter is reduced below a predetermined value.
