Abstract: PURPOSE:To avoid production of any unnecessary output reduction at quick acceleration time by performing delay control in accordance with a delay amount which is used at production time of a knocking and resetting the delay amount, which is used at the production time of the knocking, to an initial value when a subsequent knocking is produced. CONSTITUTION:When a quick acceleration condition of an engine 14 is sensed from a sensing signal of a throttle sensor 18, and ignition timing control part 34 sets an initial value of a delay amount which is used for compensating of ignition timing and gradually attenuated with time. When a production of a knocking is subsequently sensed by a knock sensor 22, the control part 34 performs delay control with respect to an ignition timing of the engine in accordance with the delay amount which is used at the produced after said delay control, the delay amount used at the production time of the knocking is reset up to an initial value. The control part performs delay control in accordance with the initial value. Production of a knocking can thereby be sufficiently suppresed without any effect of unnecessary output reduction and deterioration of accelerating feeling at a quick acceleration time.

Abstract: PURPOSE:To make it possible to optimize the ignition timing of an engine, by controlling the spark advance in accordance with the value of spark advance having such a characteristic that spark retardation is made as the load is increased, exceeding a spark advance value for high octane number fuel only when the octane number of fuel is below a predetermined octane number and upon judgement of knock controlling range. CONSTITUTION:An electronic control circuit 38 judges whether the octane number of used fuel is higher than a predetermined octane number or not, that is, whether the fuel is regular gasoline or not in accordance with the knocking condition of an engine which is indicated by a signal from a knocking sensor 32, and further, judges whether the engine is operated in a knock controlling range or not. When it is judged that a low octane number fuel is used and the engine is operated in the knock control range, the ignition timing is controlled in accordance with the value of a second spark advance having a characteristic which is subjected to spark retardation in accordance with the load of the engine. Accordingly, even if regular gasoline is used in a gasoline engine specified to be used with high octane number fuel, optimum operation may be obtained over the entire operating range.

Abstract: PURPOSE:To improve responsiveness to control, by closing a control valve at faster speed than an on-off speed in time of feedback control when the control valve inside a bypass circuit installed so as to bypass a throttle valve is largely opened in time of an engine speed being dropped. CONSTITUTION:An idling speed control valve 16A to be controlled by a pulse motor 16 is installed in a bypass circuit 14 installed so as to bypass a throttle valve 8 installed in a suction passage of an internal-combustion engine. This pulse motor 16 controls the control valve 16A with the specified period at a time when a feedback (FB) control condition is materialized by an electronic control circuit 44, and also controls the feedfback so as to turn an engine speed in time of idling to the desired engine speed. When the engine speed becomes less than the specified value, the valve 16A is opened larger as far as the specified opening than that in time of the feedback control, and after this valve opening, when the FB control condition is materialized and the engine speed is higher than the desired one, the valve 16A is controlled so as to close it up to the opening below the said specified one at a shorter period than the said specified one.

Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of the purification function of a purification device installed in a hybrid car. SOLUTION: When an S position is selected as a shift position, and an accelerator opening Acc is a value 0, and the oxygen occlusion of a purification device for purifying the exhaust gas of an engine is within the extent of below a threshold (S120), the motoring of the engine is performed at the target number of revolutions while fuel supply is stopped, and motoring control for controlling the engine and motors MG1 and MG2 is executed so that braking torque based on a request braking torque can be output to a driving shaft (S130 to 200), and when the oxygen occlusion exceeds the threshold, the target number of revolutions of the engine is set as the idle number of revolutions restricted in comparison with the case of motoring control (S210), and the engine is operated by the set target number of revolutions. Thus, the number of revolutions of the engine is restricted when the deterioration of the purification function of the exhaust gas of a purification device is predicted so that the quantity of oxygen to be supplied to the purification device can be reduced.

Abstract: PROBLEM TO BE SOLVED: To execute idle stabilization correction of an internal combustion engine without risk of stalling the internal combustion engine. SOLUTION: An engine ECU sets time constant τ corresponding to elapsed time t to a value smaller than time constant τc after time tc (S310), and calculates idle stabilization reference Nref according to the equation of Nref=previous Nref+(Ne-previous Nref)/τ (S320). Until the time tc is reached or until idle stabilization correction is started, steps 300-330 are repeated. According to this, the idle stabilization reference Nref rapidly gets close to rotating speed Ne of an engine 22. When the time tc is reached a difference ΔN is calculated by subtracting the idle stabilization reference Nref from the rotating speed Ne of the engine 22 (S340), an ignition timing correction quantity (a) corresponding to the difference Δ N (S350) is determined, and the ignition timing is corrected based on the ignition timing correction quantity (a) (S360).
