초록 ▼

In an internal combustion engine equipped with an injector for cylinder-inside injection to inject fuel into a cylinder and an injector for intake port injection to inject fuel into an intake port, both the injectors being switched for use depending upon operating conditions, wherein when an operating condition range using either one of the first or the second injector is switched to an operating condition range using the other one thereof, the amount of fuel to be injected by the either one of the first or the second injector is gradually decreased and the amount of fuel to be injected by the other one is gradually increased over a predetermined period during the switching. Further, at the time of the switching, at least one of ignition timing and throttle opening angle is gradually varied.

대표청구항 ▼

1. A control system for an internal combustion engine equipped with a first injector for cylinder-inside injection to inject fuel into a cylinder at a high load, and a second injector for intake port injection to inject fuel into an intake port at low and medium loads, both of the first and second injectors being switched for use depending on operating conditions, the control system comprising:a control unit which performs a switching control in such a way that when an operating condition range using either one of the first or the second injector is switched to an operating condition range using the other one thereof, the amount of fuel to be injected by the either one of the first or the second injector is gradually decreased and the amount of fuel to be injected by the other one is gradually increased over a predetermined period during the switching.2. The control system for the internal combustion engine according to claim 1, wherein:said control unit controls at least either one of throttle valve opening angle or ignition timing so that at least the either one of the throttle valve opening angle or the ignition timing is changed gradually from an optimum value in the operating condition range using the either one of the first or the second injector to an optimum value in the operating condition range using the other one over the predetermined period during the switching.3. A control system for an internal combustion engine equipped with a first injector for cylinder-inside injection to inject fuel into a cylinder and a second injector for intake port injection to inject fuel into an intake port, comprising:a detector to detect an operating condition of the internal combustion engine;a switching section to switch from a fuel injection by either one of the first or the second injector to a fuel injection by the other one depending on the operating condition detected by the detector; anda fuel injection quantity changing section to gradually decrease the amount of fuel to be injected by the either one of the first or the second injector while increasing the amount of fuel to be injected by the other one over a predetermined period during the switching by the switching section.4. The control system for the internal combustion engine according to claim 3, wherein:the fuel injection by the first injector is performed at a high load and the fuel injection by the second injector is performed at low and medium loads.5. The control system for the internal combustion engine according to claim 4, wherein:the predetermined period during the switching is determined at an optimum value in accordance with the operating condition.6. The control system for the internal combustion engine according to claim 5, further comprising:a changing section for at least either one of throttle valve opening angle or ignition timing to gradually change at least the either one of the throttle valve opening angle or the ignition timing from an optimum value in the operating condition range using the either one of the first or the second injector to an optimum value in the operating condition range using the other one over the predetermined period during the switching.7. A control method for an internal combustion engine equipped with a first injector for cylinder-inside injection to inject fuel into a cylinder, and a second injector for intake port injection to inject fuel into an intake port, the control method comprising the steps of:detecting an operating condition of the internal combustion engine;switching from a fuel injection by either one of the first or the second injector to a fuel injection by the other one depending on the detected operating condition; andgradually decreasing the amount of fuel to be injected by the either one of the first or the second injector while gradually increasing the amount of fuel to be injected by the other one over a predetermined period during the switching.8. The control method for the internal combustion engine according to claim 7, wherein:the fuel injection by the first injector is performed at a high load and the fuel injection by the second injector performed at low and medium loads.9. The control method for the internal combustion engine according to claim 8, wherein:the predetermined period during the switching is determined at an optimum value in accordance with the operating condition.10. The control method for the internal combustion engine according to claim 9, further comprising the step of:gradually changing at least either one of throttle valve opening angle or ignition timing from an optimum value in the operating condition range using the either one of the first or the second injector to an optimum value in the operating condition range using the other one over the predetermined period during the switching.
