Abstract: PURPOSE:To make optimum asynchronous injection corresponding to a driving state performable, by setting a fuel quantity of the asynchronous injection according to a fuel cut release condition when it comes to fruition during fuel cut performance. CONSTITUTION:In case of a fuel injection controller which installs a solenoid- operated fuel injection valve in a suction pipe and controls the fuel supply, when a fuel cut release condition comes to fruition (P5) during fuel cut performance (P4), a fuel quantity of asynchronous injection is determined on the basis of a driving state of an internal-combustion engine (P7). Therefore, during the fuel cut performance, when a throttle valve is full-close whereby an engine speed drops and the fuel cut is released, if the asynchronous fuel injection quantity is set on the basis of a warm-up state, the fuel quantity is at once increased to the quantity required and restored, thus responsiveness is securable without entailing an unexpected drop in output.

Abstract: PURPOSE:To prevent a misfire and any damage to a catalyzer from occurring, by performing a fuel cut as soon as a rich period of an air-fuel ratio signal exceeds the specified value at a time when an engien speed is more than the specified value and a throttle valve is not fully closed. CONSTITUTION:In case of an air-fuel ratio controller for an internal-combution engine, when an engine speed is more than the specified value and a throttle valve is not fully closed, if a required fuel injection quantity is smaller than the setting value and a rich period of an air-fuel ratio signal exceeds the specified time, fuel is cut. With this constitution, in time of driving on a downhill under the condition that the throttle valve is a little opened, these possibilities that an air-fuel ratio is made into being overrich and thereby a misfire occurs and a catalyzer is damaged are all preventable.

Abstract: PURPOSE:To prevent the smoldering of a spark plug and an engine stall both from occurring, by increasing a fuel quantity only at the specified time in time of fuel-cut resetting during engine warming up. CONSTITUTION:A fundamental fuel injection quantity is calculated by a fundamental fuel injection quantity operational device according to the specified driving state parameter, and a fundamental injection quantity in time of warming up is compensated with a warm-up increment value f0 calculated according to engine cooling water temperature THW.

Abstract: PURPOSE: To prevent the reduction of the driving performance of a fuel pump by increasing the driving current for the fuel pump immediately after low-temperature start or the reduction of capacity of a battery having a low power voltage supplied into a driving-current circuit which generates the driving current for the fuel pump.
CONSTITUTION: When the discharge amount of a fuel pump is less than a fuel injection amount, a signal is supplied into the transistor 39 of a fuel pump controller 36 from a control circuit 32, and the coil 38b of a relay 38 is put into electric conduction to turn-ON a contract point 38a. Then, the voltage of a battery is directly supplied into a fuel pump 42 through the contact point 38a, not through a resistor 37. When the discharge amount is over the fuel injection amount and the power voltage of the battery is over a prescribed value, the contact point 38a is turned-OFF, and the voltage of the battery 34 is reduced through the resistor 37 and supplied into the motor of the fuel pump 42, which is driven at a low speed. When the power voltage is lower than a prescribed voltage, the contact point 38a is turned-ON, and the battery voltage is directly applied into the fuel pump 42.

Abstract: PROBLEM TO BE SOLVED: To perform a control, when restarting an internal combustion engine stopped once during the operation of a vehicle, so as to satisfy both the cases necessitating vehicle driving force and the necessity of suppression of body vibration or the like. SOLUTION: When vehicle driving force is required, ignition period is set to A at the beginning, and then advanced by a (S218). When the suppression of body vibration is required, the ignition period is set to B retarded from A at the beginning, and thereafter set to b smaller than a. Accordingly, when the suppression of body vibration is required, the ignition period is retarded to reduce a shock or the like. When the driving force is required, the ignition period is advanced more than in the necessity of vibration suppression, and a general output can be obtained more quickly. COPYRIGHT: (C)2004,JPO

Abstract: PURPOSE:To leave the output air-fuel ratio as it is even though a knock occurs in a lean control period, and to improve the fuel consumption and the output, by stopping the fuel increase depending on the delay angle control of the ignition time while the air-fuel ratio is being lean-controlled. CONSTITUTION:A lean control device B to exercise the lean control to make the air-fuel ratio equal to the output air-fuel ratio, when the exhaust gas temperature detected by an exhaust gas temperature sensor A is below a specific value, is provided. And an ignition time delay angle device D to delay the angle of the ignition time, when a knock is detected by a knock sensor C, is provided. Responding to the delay angle amount of the ignition time delay angle device D, the fuel is increased by a fuel increase device E. In this case, when the lean control is being performed by the lean control device B, the fuel increase by the fuel increase device E is stopped by an increase stop device F. Thereby, while the air-fuel ratio is lean-controlled, the fuel increase is stopped even though a knock occurs, and the fuel consumption is reduced.

Abstract: PURPOSE:To prevent the temperature in an exhaust system from increasing to high level, by incrementing fuel when the exhaust gas temperature is higher than a target level which is set to be higher for high speed area or heave load area. CONSTITUTION:A control circuit 10 operates a basic fuel injection based on an intake air flow fed from an air flow meter 3 and rotations fed from crank angle sensors 5, 6. Then said basic fuel injection is corrected in many ways based on the values detected through a water temperature sensor 13, an O2 sensor 14, etc. so as to control a fuel injection valve 11. The control circuit 10 reads out a target exhaust temperature from a data map corresponding to the basic fuel injection and the rotation and makes comparison with a value detected through an exhaust temperature sensor 18. When the temperature detected through the exhaust temperature sensor 18 is higher than the target exhaust temperature, fuel being injected from a fuel injection valve 11 is incremented.

Abstract: PURPOSE:To make it possible to maintain low the required ignition voltage, in a fuel cut condition for performing a fuel supply stop in order to prevent a over-revolution, by correcting an ignition timing set by means of an ignition timing setting means to an advance side. CONSTITUTION:A desired ignition timing corresponding to an operating condition of an internal combustion engine is set by a ignition timing setting means 2 and the ignition is performed by an ignition control means 1. Further, fuel corresponding to the operating condition is supplied to the internal combustion engine by a fuel supply control means 3. In this way, a fuel cut condition for performing the stop of the fuel supply in order to prevent the over-revolution by the fuel supply control means 3, is judged by a fuel cut condition judging means 4. Thus, in the fuel cut condition, an ignition timing set by the ignition timing setting means 2 is corrected to an advance side by an ignition timing advance correcting means 5. Therefore, it is possible to maintain low the required ignition voltage so as to prevent the leak in the ignition circuit.
