摘要： A fuel injection control system for an internal combustion engine which can eliminate lean misfiring and rich misfiring at asynchronous injection and exhausting of non-combustioned HC. When the asynchronous injection is performed at engine cranking or at acceleration, a judgement is made as to whether the injected fuel will be divided by closure of an intake valve. When division is not detected, fuel injection is performed in normal manner. When division is detected, rate of the fuel division is computed. As a result of computation, fuel injection is performed when judgement is made that a predetermined amount of the injected fuel will be introduced into the cylinder. Furthermore, the amount of fuel not introduced into the cylinder is computed to reduce a corresponding amount from a fuel injection amount for the next cycle. On the other hand, when judgement is made that the predetermined amount of fuel will not be introduced into the cylinder, fuel injection does not take place.

摘要： A system for controlling the air-fuel ratio in which the amount of fuel injected into the engine is controlled in accordance with the flow rate of air passing through an air intake pipe including a throttle valve for introducing the air into the engine and the engine operating conditions. A bypass of the air intake pipe is opened or closed to change the air-fuel ratio of the mixture to slightly richer and leaner sides of a basic air-fuel ratio, and the change of the engine output conditions based on the change of the air-fuel ratio is used to correct the air-fuel ratio in an optimum direction. On the basis of a parameter indicating the engine operating conditions such as the detection value of the intake pipe pressure, a control is made to introduce the air which passed through the bypass to one of the upstream or downstream portion of the throttle valve.

摘要： An electronically-controlled fuel injection system includes electromagnetic fuel injection valves each of which is mounted in each cylinder of an internal combustion engine, and the injection of fuel during the starting period of the engine is also effected only by these fuel injection valves. During the starting period of the engine, the duration of the opening of the fuel injection valves is controlled at a constant value irrespective of the rotational speed of the engine until the rotational speed reaches a value corresponding to the initial combustion of fuel in the engine, after which the duration of the opening of the fuel injection valves is controlled in relation to the rotational speed of the engine. Further, during the time that the starter motor is in operation, the duration of the opening of the fuel injection valves which was basically determined in the previously mentioned manner is increased to a great extent in accordance with the temperature of the engine until the engine rotational speed reaches a value corresponding to the complete combustion of fuel in the engine.

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.
