摘要： PURPOSE:To improve combustibility by injecting fuel through a fuel injection valve on the downstream side in a low and a high rotation region and injecting fuel through a fuel injection valve on the upper stream side in a middle rotation region. CONSTITUTION:Since the velocity of flow of intake air in a suction passage 4 is low in a low rotation region and a user does not expect too much of promotion of vaporization and atomization of fuel in intake air, response of an output change to a change in a fuel injection amount is improved through injection of fuel through a fuel injection valve 19 on the downstream side. Since turbulence of intake air is high in a middle rotation region and vaporization and atomization of fuel in intake air are promoted, fuel is injected through a fuel injection valve 17 on the upper stream side, and combustibility of fuel-air mixture is improved. Since the velocity of flow of intake air is extremely increased in a high rotation region, fuel is injected through a fuel injection valve 19 on the downstream side, and collision and adhesion of fuel with and on the inner peripheral surface of the suction passage 4 are reduced. This constitution improves combustibility.

摘要： PURPOSE:To enhance accuracy in a learning correction value by limiting correction and renewal of the learning correction value when the deviation of an intake passage length from a target value is larger than a predetermined reference deviation. CONSTITUTION:In a rotary piston engine RE, an intake passage length adjusting means 16 is provided in an intake passage 4, so that the suction passage length is controlled to an target intake passage length determined according to the operation state of the engine RE via an actuator 27 controlled by a control unit 40. The control unit 40 also corrects and renews the learning correction value according to the deviation between a target air-fuel ratio and an actual air-fuel ratio. In the case where the deviation of the intake passage length from the target length is larger than predetermined reference deviation, correction and renewal of the learning correction value are limited. Therefore, the deviation in the air fuel ratio when the intake passage length is changed, is not incorporated in the learning correction value, so that accuracy in the learning correction value can be enhanced and accuracy in the control of the air-fuel ratio can be enhanced.

摘要： PURPOSE:To sufficiently secure a quantity of fuel to be discharged into an engine, by providing a voltage control means for variably controlling a voltage to be applied to a motor for driving a fuel pump according to a battery voltage condition to be detected by a voltage condition detecting means. CONSTITUTION:A voltage condition of a battery 5 is detected by a control unit 11, and when the voltage condition is lower than a predetermined value, the control unit 11 sets a predetermined value Qa=alpha for a suction air quantity Q, and decides the value of the suction air quantity Q, thus controlling opening and closing of a break contact 8b of a relay switch 8. On the other hand, when the voltage condition of the battery 5 is higher than the predetermined value, the control unit 11 sets a predetermined value Qa=beta for the suction air quantity, and decides the value of the suction air quantity Q, thus controlling opening and closing of the break contact 8b of the relay switch 8. Accordingly, even when the voltage condition of the battery is low, a voltage to be applied to a motor 2 for driving a fuel pump 1 may be secured, and thereby a sufficient quantity of fuel to be discharged into an engine may be secured.

摘要： PURPOSE:To improve the fuel consumption performance and running properties by correcting and updating the learning correction value of a learning operation region before deviation based on a feedback running-in value right before deviation when the operation state of an engine is deviation from a learning operation region to a different operation region. CONSTITUTION:When the running state of an engine RE is within a preset feedback control region, a control unit 40 performs feedback control of a fuel injection amount. When it is within a leaning operation region set to a region within a feedback control region, the control unit performs feedback control of a fuel injection amount along with learning correction, and when it is outside the feedback control region, feedback control of a fuel injection amount is stopped. Further, the control unit 40 performs control of an air-fuel ratio by correcting and updating a learning correction value based on hysteresis of a feedback correction value. This constitution improves the fuel consumption performance and running properties.

摘要： PURPOSE:To improve fuel consumption and to enable excellent cleaning of exhaust gas, by a method wherein a change in the fluctuation width of the rotation speed of an internal combustion engine is detected, and according to the change, the air-fuel ratio of the internal combustion engine is varied. CONSTITUTION:A detecting means M1 detects the fluctuation width of a rotation speed during non-load running of an internal combustion engine. A varying means M2 varies an air-fuel ratio so that the fluctuation width of the rotation speed is decreased. In this case, a change in the fluctuation width of the rotation speed is detected by a detecting means M3. When a change in the fluctuation width of the rotation speed is produced, based on the change, the varying means M2 is controlled by a first control means M4 so that an air-fuel ratio is brought into the lean side or the rich side. Meanwhile, when there is no change, the varying means M2 is controlled by a second control means M5 so that an air- fuel ratio is brought into the lean side. This constitution improves fuel consumption during non-load running, and cleans exhaust gas in an excellent state.

摘要： PURPOSE:To aim at improvements in drivability, by making an asynchronous injection quantity at the time of acceleration immediately after starting marger, but making it smaller dradually with the elapse of time from just after the starting and, after the specified time lapses, setting it to sameness as the asynchronous injection quantity at the time of normal acceleration. CONSTITUTION:A main fuel supply is calculated by a calculating device M14 on the basis of the engine running state detected by a running state detecting device M2. According to this calculated result, a fuel supplying device M3 is controlled for operation by a synchronous fuel supply controlling device M5, while when an acceleration judging device M6 judges a state of acceleration, the supplying device M3 is controlled by an asynchronous fuel supply controlling device M7. In this case, there is provided with an elapsing state detecting device M8 which detects a total engine speed from just after engine starting and the time elapsed. An auxiliary fuel supply out of the fuel supplying device M3 at the time of being controlled by the controlling device M7 is made so as to be compensated to reduce according to the elapsing state detecting device M8 by a compensating device 9.
