    摘要: When first switching of switching from a first purge of supplying evaporated fuel gas to an intake pipe through a first purge passage to a second purge of supplying the evaporated fuel gas to the intake pipe through a second purge passage occurs and then second switching of switching from the second purge to the first purge occurs, a purge concentration-related value is corrected to a value closer to a first stored value that is the purge concentration-related value immediately before the first switching than to a second stored value that is the purge concentration-related value immediately before the second switching.

    摘要: A control system includes a controller. The controller counts the number of driving times of a high pressure fuel pump, which is the number of reciprocating motions of a plunger based on a crank counter. The controller estimates a high pressure system fuel pressure based on the calculated number of driving times, a fuel temperature detected by a fuel temperature sensor, and a low pressure system fuel pressure detected by a low pressure system fuel pressure sensor when the high pressure system fuel pressure is not able to be acquired from a high pressure system fuel pressure sensor. The controller sets an opening period of an in-cylinder fuel injection valve based on the estimated high pressure system fuel pressure and to perform an engine start by an in-cylinder fuel injection when the high pressure system fuel pressure is not able to be acquired from the high pressure system fuel pressure sensor.

    摘要: A controller for an internal combustion engine includes processing circuitry. The processing circuitry is configured to execute an estimation process that estimates a density parameter of fuel in an upper layer portion of a delivery pipe and a density parameter of fuel in a lower layer portion of the delivery pipe and an operation process that includes acquiring a density parameter of the fuel injected from a fuel injection valve and operating an operation unit of the internal combustion engine based on the acquired density parameter. The estimation process includes a process that assumes that when the density of the fuel flowing into the delivery pipe is high, a greater proportion of the fuel flowing into the delivery pipe flows into the lower layer portion than when the density of the fuel flowing into the delivery pipe is low.

    摘要: A control apparatus for an internal combustion engine includes an electronic control unit configured to i) perform a fuel introduction process, ii) calculate a total injection amount in the fuel introduction process, and control each of fuel injection valves based on a required injection amount per cylinder when the fuel introduction process is performed, and iii) perform a cylinder deactivation process for stopping fuel from being injected for one or some of cylinders, and controlling each of the fuel injection valves such that an amount of the fuel obtained by dividing the total injection amount is injected for a cylinder or cylinders other than the one or some of the cylinders for which the fuel is stopped from being injected, when the fuel introduction process is performed.

    摘要: A fuel injection controller for an internal combustion engine includes first and second calculation sections. The first calculation section acquires a fuel pressure at a predetermined point of time before an injection starting point of time and calculates an injection time using the acquired fuel pressure. The second calculation section acquires a fuel pressure when the injection starting point of time arrives and calculates the injection time by using the acquired fuel pressure. The controller is configured to, before starting the energization to the injector, set a point of time to stop energization to an injector based on a calculation result of the injection time by the first calculation section. The controller is also configured to, after starting the energization to the injector, reset the point of time to stop the energization to the injector based on a calculation result of the injection time by the second calculation section.

    摘要: A drive system for fuel injection valves includes a battery, a capacitor, a drive control unit and an electronic control unit. The electronic control unit is configured to, when an energization start interval between a start of energization of a last one of the fuel injection valves and a start of energization of a current one of the fuel injection valves is longer than or equal to a peak reaching time of a last one of the fuel injection valves, extend an energization time of the current one of the fuel injection valves as the energization start interval reduces. The electronic control unit is configured to, when the energization start interval is shorter than the peak reaching time, reduce the energization time of the current one of the fuel injection valves is energized as the energization start interval reduces.

    摘要: When the vehicle is stopped and removal of deposits is not required, and forced charging of a power storage device is not being performed, the controller controls the fuel supply device so that a supply fuel pressure is at the first fuel pressure. When the vehicle is stopped and the removal of deposits is required, and the forced charging of the power storage device is being performed, the controller controls the fuel supply device so that the supply fuel pressure is at a second fuel pressure higher than the first fuel pressure. When the vehicle is stopped and the removal of deposits is required, and the forced charging of the power storage device is not being performed, the controller controls the fuel supply device so that the supply fuel pressure is at a third fuel pressure higher than the first fuel pressure and lower than the second fuel pressure.
