摘要： In an air-fuel ratio control system for an engine, when the engine is driving at a specified operating condition such as an acceleration or deceleration condition, the air-fuel ratio is controlled at a stoichiometric air-fuel ratio. During a steady-state operating condition following the termination of the specified operating condition the air-fuel ratio is gradually changed from the stoichiometric air-fuel ratio to a leaner air-fuel ratio which provides the optimum fuel consumption and the air-fuel ratio for optimum fuel consumption is maintained until the engine again comes to the specified operating condition. The change to the optimum fuel consumption air-fuel ratio takes place immediately after the termination of the specified operating condition or after the expiration of a given time after the termination of the specified operating condition.

摘要： In an optimum control for an internal combustion engine, a engine is operated by dithering the value of a selected one of engine operating control variables from a value of the selected control variable which is obtained by calculation in accordance with detected values of operating parameters of the engine, and a direction of improving either one of a fuel consumption rate and an output of the engine is decided on the basis of a detected change of an engine operating condition, thereby correcting the value of the selected control variable. In the optimum control, the time period for detecting a change of an engine speed within the time period for effecting the dithering is increased or decreased as the engine speed increases or decreases, respectively. Thus, this optimum control makes it possible to perform accurate control with a reduced dither quantity and a shorter dither period than previously.

摘要： In an air-fuel ratio control system the air-fuel ratio is changed by changing the auxiliary air supply amount in a bypass path with respect to a main path for supplying air to the engine in the vicinity of an optimum air-fuel ratio. Signals representing the operating conditions such as rotational speed of the engine operated at the resulting different air-fuel ratios are detected at a plurality of operating points. The signals thus detected are compared and the fuel injection amount is regulated thereby to correct the air-fuel ratio so that the fuel consumption rate may become optimum.

摘要： Spark ignition timing of an internal combustion engine is oscillated on each side of a variable reference setting by varying it at stepwisely variable amounts during positive and negative swings and the resultant engine speed is detected in at least three successive phases. The detected engine speed values are compared one against each other to determine whether they satisfy one of two specified conditions. The variable reference is adjusted in a direction toward an optimum position depending on which one of the conditions is satisfied.

摘要： The timing of spark ignition is set in normal operating conditions at a programed spark advance angle corresponding to the MBT (minimum spark advance for best torque). When knocking of the engine is detected by a vibration sensor, the ignition timing is delayed by a predetermined amount, e.g., 2.DELTA..theta., for each engine cycle that knocking is detected in synchronism with the rotation of the engine. When knocking is not detected, the ignition timing is advanced by another predetermined amount, for each engine cycle that knocking is not detected. e.g., .DELTA..theta.. In this method for controlling the spark timing, the amount of retardation, 2.DELTA..theta., is selected to be larger than the other amount of advance, .DELTA..theta..

摘要： A control circuit for a fuel injection system used with internal combustion engines, of the type in which fuel injection valve control pulses are generated whose duration depends on engine data, in particular engine rpm and air flow rate. To avoid misfires when the engine is run fast with a closed throttle, the fuel supply is shut off by suppression of the fuel control pulses. For this purpose, the control circuit generates a reference rpm value and a reference pulse train of predetermined pulse duration and compares the duration of the actual fuel injection control pulses with the predetermined duration and, at the same time, it compares the actual rpm with the reference rpm. If the actual pulse duration is less than the reference duration and if the actual rpm is greater than the reference rpm, the control circuit suppresses the fuel injection control pulses.

摘要： An air/fuel ratio control system for an internal combustion engine that compensates, the amount of fuel supplied at engine starting based on lapsed time since the engine was operated and stopped. A lapse time from the immediately previous engine stop to the subsequent engine start is determined. Based on this lapse time, an increase value of fuel to be supplied into the engine's intake air by fuel injection valves is determined. This increase value is determined according to a pre-established of fuel temperature. The fuel supply amount is corrected upon engine start on the basis of the increase value.
