CONSTITUTION:Integration takes place according to output of a concentration sensor (a) emitting output commensurate to oxygen content in exhaust gas, and there is provided with a first integrating device (b) making out a first compensation factor to control an air-fuel ratio to a theoretical air-fuel ratio. In addition, the integration takes pace according to the output of the concentration sensor (a), there is provided with a second integrating device (c) making out a second compensation factor to control the air-fuel ratio to a desired air-fuel ratio at the lean side from the theoretical air-fuel ratio. At this time, at least either of a constant of integration of the first integrating device (b) or a skip value is set to be larger than that of the second integrating device (c). And, both first and second compensation factors by each of these integrating devices (b) and (c) are selectively used according to a running state whereby the air-fuel ratio is controlled by a feedback controlling device (d)

Abstract: PURPOSE: To reduce discontinuous combustion and a shock in an engine and improve its fuel consumption, by providing a means, which measures a number of engine cycles or an elapsed time after a fuel cut is reset, and a fuel increasing means increasing fuel after an accelerative condition of the engine is detected.
CONSTITUTION: A fuel cut reset time detecting means detects the fuel cut reset time of an internal-combustion engine of single point injection type. An after- reset cycle number or time measuring means measures a number of engine cycles or an elapsed time after a fuel cut is reset. A fuel increasing means increaes fuel in accordance with the number of engine cycles or the elapsed time after an accelerative condition of the engine is detected. In this way, the engine, enabling its discontinuous combustion and shock to be reduced, improves also fuel consumption.

Abstract: PURPOSE:To stabilize an idling operation by detecting an increase of the electrical load and setting the air-fuel ratio to the rich side than normal or setting the ignition timing to the advance angle side than normal during the idling operation. CONSTITUTION:A judging means is provided detecting the operating condition depending on whether a predetermined idling judging requirement is satisfied or not. In addition, a judging means is provided detecting the condition of preset electrical equipment of a car and judging whether the usage of the electrical load is large or not depending on whether the predetermind load requirement is satisfied or not. If it is judged that the idling operating condition exists and also the usage of the electrical load is large by these judging means, the air- fuel ratio is set to the rich side than normal or the ignition timing is set to the advance angle side than normal via an engine speed increasing means. Thereby, the engine speed is increased and the idling operation is stabilized.

Abstract: PURPOSE:To control the air-fuel ratio appropriately, by increasing the quantity of fuel supplied to cylinders to which asynchronous injection is not applied, at the time just after asynchronous injection is effected. CONSTITUTION:An electronic control circuit 30 controls fuel injection according to a control program. That is, the operational conditions of an internal combustion engine is detected at first. At the next step, whether asynchronous injection is to be effected or not is judged. In case of YES, asynchronous injection is effected. Then, the quantity of fuel supplied to cylinders to which asynchronous injection is not applied is increased. Thus, it is enabled to control the air-fuel ratio appropriately.

Abstract: PROBLEM TO BE SOLVED: To always execute appropriate homogeneous combustion while a tumble flow is sufficiently reinforced and kept immediately before an ignition timing even when the tumble flow generated in an intake stroke is relatively weak.
SOLUTION: In the intake stroke, the tumble flow T turning upward at an intake port 15 side and downward at an exhaust port 16 side in a combustion chamber 10 is generated by air supplied from the intake port 15. Fuel is injected in the combustion chamber 10 in a latter half of the compression stroke by a fuel injection valve 21 provided near the intake port 15 of a cylinder head 14. This fuel spray collides with and reflects from a guide part formed at the intake port side of a piston top face 19 and deflects in a flowing direction of the tumble flow T. Thus, the tumble flow T is reinforced.
