CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

An internal combustion engine of the present invention is an internal combustion engine equipped with port injectors. Further, the internal combustion engine has an ISC passage that connects an upstream side and a downstream side of a throttle valve in an intake passage, and an ISC valve that regulates an amount of air flowing in the ISC passage. A control device of the present invention performs valve opening control that makes an opening degree of the ISC valve an opening degree larger than a reference opening degree when request torque required by the internal combustion engine is smaller than estimated torque that can be generated in the internal combustion engine, and sets a timing for fuel injection from the port injector at an opening timing of an intake valve of a cylinder in which the port injector is installed during the valve opening control.

主权项

1. A control device for an internal combustion engine, comprising:
a throttle valve that is installed in an intake passage of the internal combustion engine including a supercharger; an ISC passage that connects an upstream side and a downstream side of the throttle valve, in the intake passage; an ISC valve that regulates an amount of air that flows in the ISC passage by being controlled to a predetermined opening degree; a port injector that is installed to inject fuel to an intake port of each of cylinders of the internal combustion engine; control means for executing valve opening control that makes an opening degree of the ISC valve an opening degree larger than a reference opening degree, when request torque required by the internal combustion engine is smaller than estimated torque that can be generated in the internal combustion engine; and restriction means for restricting a timing for fuel injection from the port injector, during execution of the valve opening control.
