Abstract: PURPOSE:To prevent the occurrence of engine stall and an abnormal reduction in an idling speed by setting the engine speed, at which an engine speed control should be started, at the speed higher by a specified amount when the temperature of fuel is determined to exceed a specified one. CONSTITUTION:Controlling is effected by an electronic control unit 20 in such a way that the temperature of engine cooling water is detected by a water temperature sensor 9, based on the resultant when an engine 1 is determined to be as low in temperature as the resultant, an ISCV 13 is left fully open until an engine speed control is started, and the ISCV 13 is not permitted to open in accordance with the engine temperature before an idling speed comes up to an engine speed, at which the engine speed control should be started. In this case, if the engine is determined to exceed a specific point in temperature when the engine is started, the engine speed, at which the engine speed control should be started, should be set at the higher value. This configuration is capable of preventing a reduction in torque which is caused by vapor taking place in fuel pipings when the engine is started at high temperature.

Abstract: PURPOSE:To reduce and prevent the noise generated in a manual operating speed change gear by controlling the delay-angle of the ignition-timing of an internal-combustion engine according to the oil temperature of the manual operating speed change gear, when the internal-combustion engine of a vehicle is in the idling state. CONSTITUTION:When a manual speed change gear and an internal-combustion engine mounted onto a car are in the idling state (P1), the delay-angle control for the ignition-timing of the internal-combustion engine is carried out according to the oil temperature of the manual operating speed change gear (P2). Said oil temperature is detected by an oil temperature sensor installed onto the manual speed change gear or is estimated from the operation state of the internal-combustion engine. Thus, the torque variation can be reduced, and the noise generated in the manual speed change gear can be reduced.

Abstract: PURPOSE:To prevent the generation of the preignition state of an engine by judging the generation of knocking when the peak value of a knock sensor exceeds a standard value and delay-angle-controlling the ignition timing of the engine in substitution for the advance-angle control. CONSTITUTION:When the peak value of a knock sensor 22 for detecting the vibration of an engine exceeds a standard value, it is judged that knocking is generated, and the ignition timing of the engine id delay-angle controlled in substitution for the advance-angle control. Then, the judgment standard value X corresponding to the engine revolution speed or load is taken-in. When the peak value P exceeds the judgment standard value X, it is judged that knocking is generated, and the ignition timing of the engine is delay-angle controlled in substitution for the advance-angle control. Thus, the generation of the preignition state of the engine can be prevented beforehand.

Abstract: PURPOSE:To certainly defect a trouble in a supercharger so that fuel cutting can be well achieved, by providing both an over-supercharge detecting means for detecting any over-supercharge and a delay means for reserving an assigned period of time until the fuel quantity is reduced to zero. CONSTITUTION:An over-supercharge detecting means is provided with a number of detecting levels equal to the number of superchargers so as to detect the presence of any over-supercharge. When presence of any over-supercharge is detected, a fuel supply quantity detecting means reduces the fuel quantity to zero. A delay means reserves a delay of an assigned period of time from the time of detecting the presence of an over-supercharge until the fuel quantity is reduced to zero. Said assigned period of time is set per each detecting level of the over-supercharge detecting means and made longer as the detecting level is lower. Any trouble in a supercharger can be certainly detected in this way so that fuel cutting can be well achieved.

Abstract: PURPOSE:To reduce manufacturing cost by discriminating the clutch-on according to the intake air quantity per rotation in the case of shift change. CONSTITUTION:Intake air quantity per rotation Q/Ne is obtained, and whether the value is below the set value or not is judged.

Abstract: PURPOSE:To improve the control accuracy by calculating the average value of actual rotation of engine at the time point when the actual idle rotation has approached to target rotation than controlling the ignition timing on the basis of the difference between said average value and the actual engine rotation. CONSTITUTION:When operating an internal-combustion engine 20, an electronic control circuit 44 will first calculate the actual engine rotation NE on the basis of the output from crank angle sensor 48 then calculate Q/NE on the basis of NE and the fuel flow flow Q to be operated with correspondence to the operating condition. Under idling where an idle switch 10 is turned off, the average ignition timing lead angle is set to a referential level. Upon detection that NE has reached within the target level range, control is started while employing NE at that time as the initial target level thus to calculate the average level of NE or NEn. Then the ignition timing lead angle is controlled on the basis on NEn and NE thus to control the engine rotation.

Abstract: PURPOSE:To enable the automatic discrimination of fuel quickly and exactly by discriminating the octane number on the basis of the knocking condition at the time when the compensation quantity of ignition delay angle which increases or decreases in accordance with the presence of knocking is within a certain range. CONSTITUTION:Denoting the output of integrating circuit 54 and that of gate circuit 55A by A and B respectively, when B is an output greater than the prescribed times (K) of A, it is discriminated that knocking exists. In a gasoline engine specified for high-octane gasoline, when knocking is occurring, by making the sum of a prescribed value and the compensation quantity THK of ignition delay angle as a new compensation quantity THK, the preceding ignition timing is delayed by this new compensation quantity. The discrimination of fuel is carried out on the basis of this compensation. And when the said new compensation quantity of ignition delay angle exists in a given region in the vicinity of the maximum value of the compensation quantity of ignition delay angle, the number of ignition between large knocks occurring successively in the CPU40 is counted, and, if the number is more than a prescribed number of ignition, the ignition control and fuel injection control for regular gasoline is carried out regarding the gasoline being used as regular gasoline.
