Abstract: A fuel injection control apparatus for an internal combustion engine includes a low pressure fuel pump, a low pressure fuel passage, a high pressure fuel pump, a high pressure fuel passage, a fuel injection valve, a high pressure controller, and a low pressure controller. The low pressure controller calculates a feedforward correction amount that increases as a request injection amount of the fuel injection valve increases and an increase rate of the high pressure target value increases when a high pressure target value increases. The low pressure controller calculates a feedback correction amount based on a low-side pressure deviation when the high pressure target value increases. The low pressure controller controls driving of the low pressure fuel pump based on a sum of the feedforward correction amount and the feedback correction amount.

Abstract: A port injection valve injects fuel into an intake passage. An intake synchronous injection is to inject fuel in synchronization with an opening period of an intake valve. A single injection process is to execute only an intake air non-synchronous injection. A majority of a fuel injection period of the single injection process is prior to the opening timing of the intake valve. A controller causes, when switching a fuel injection process from the single injection process to a multiple injection process, an injection start timing of the intake air non-synchronous injection to be more advanced than an injection start timing of the single injection process prior to the switching.

The fuel injection control device includes a port warm-up judgment section, which judges whether the intake port has been warmed up, and an injection mode determination section, which determines the injection mode based on the engine speed and a predicted load rate. When determining the injection mode at the cold operation of the internal combustion engine, the injection mode determination section sets the range of the operation region of the internal combustion engine in which the direct-injection-only mode is selected as the injection mode to be broader in a case in which the port warm-up judgment section has judged that the port has not been warmed up than in a case in which the port warm-up judgment section has judged that the port has been warmed up.

Abstract: An electronic control unit performs a cylinder-by-cylinder correction of a fuel injection amount to cause differences among air-fuel ratios of air-fuel mixture burned in multiple cylinders. In a case in which the cylinder-by-cylinder correction of the fuel injection amount results in a cylinder in which combustion is performed at an air-fuel ratio richer than an output air-fuel ratio, the output air-fuel ratio being an air-fuel ratio at which combustion torque is maximized, the electronic control unit performs a cylinder-by-cylinder correction of ignition timing such that the ignition timing of the cylinder in which combustion is performed at the air-fuel ratio richer than the output air-fuel ratio becomes more advanced than the ignition timing of the other cylinders.

Abstract: A port injection valve injects fuel into an intake passage. A base injection amount is an injection amount proportional to an amount of fresh air introduced into a cylinder of an internal combustion engine. A division process involves dividing the base injection amount into a synchronous injection amount and an asynchronous injection amount. In an intake-synchronous injection, the fuel is injected in synchronization with a period in which an intake valve is open. In an intake-asynchronous injection, the fuel is injected at a time advanced with respect to the intake-synchronous injection. In a selective correction process, the asynchronous injection amount is corrected according to a required correction amount for the base injection amount, and the synchronous injection amount is not corrected.

Abstract: 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.

Abstract: A fuel injection amount control device controls a fuel injection amount of an injector in an internal combustion engine including a blow-by gas ventilation system. The fuel injection amount control device includes a reflection rate setting section, a dilution correction section, and a dilution learning section. The reflection rate setting section sets a reflection rate proportional to the amount of a blow-by gas discharged to an intake air. The dilution correction section corrects a fuel injection amount by using, as a correction value, the product obtained by multiplying a reflection rate by a dilution learning value. The dilution learning section updates the dilution learning value such that an air-fuel ratio F/B correction value approaches 0 on the condition that a fuel dilution amount of engine oil is equal to or greater than a predetermined value.

The exhaust purification device performs an anomaly determination of the differential pressure sensor based on the state of the differential pressure sensor from stopping of the internal combustion engine to a startup thereof, and corrects the first estimated amount PMf based on the second estimated amount PMc when starting the internal combustion engine. The exhaust purification device calculates, as the PM deposition amount Pr, the larger value of the first and second estimated amounts, and starts a filter regeneration control of the PM filter when the PM deposition amount Pr is equal to or more than a first predetermined amount.

Abstract: An electronic control unit is configured to switch a drive mode of a first high-pressure fuel pump and a second high-pressure fuel pump, in accordance with an operating state of an internal combustion engine, either to a twin-drive mode, in which both the first high-pressure fuel pump and the second high-pressure fuel pump are driven, or to a single-drive mode, in which either one of the first high-pressure fuel pump and the second high-pressure fuel pump is driven. The electronic control unit is configured to determine whether or not a pump ambient temperature, which is the ambient temperature of the first high-pressure fuel pump and the second high-pressure fuel pump, is equal to or higher than a predetermined first temperature. In a case where the pump ambient temperature is equal to or higher than the first temperature, the electronic control unit turns ON a twin-drive mode request flag.

Abstract: A fuel injection controller updates an air-fuel ratio learning value such that the amount of correction of a fuel injection amount according to an air-fuel ratio feedback correction value approaches zero. Further, the fuel injection controller makes an update rate of the air-fuel ratio learning value lower when the variation among respective-cylinder correction values, which are set for the respective cylinders in order to differentiate air-fuel ratios of a plurality of cylinders, is great than when the variation among the respective-cylinder correction values of the cylinders is small.

Abstract: A wastegate opens and closes the flow path of a bypass passage that bypasses the turbine of a forced-induction device. A processor changes the drive current for the electric actuator in a stepwise manner from a state where the wastegate is stationary in a given standstill position. The amount of change in the drive current that is made until the wastegate is determined to be moved is learned as a learning value. A requested drive current for moving the wastegate to a target opening degree is corrected based on the learning value.

Abstract: A controller includes a P/L learning unit that performs P/L learning, a purge learning unit that performs purge learning, an air-fuel ratio learning unit that performs air-fuel ratio learning, and a storage unit that stores learning result. When the learning result of each learning process is not stored in the storage unit at the time of engine start, the P/L learning unit learns an injection characteristic of an in-cylinder injection valve through the P/L learning process whenever the in-cylinder injection valve performs the P/L injection and interrupts the P/L learning process before the P/L learning process is completed. The purge learning unit performs the purge learning process, and the air-fuel ratio learning unit starts the air-fuel ratio learning process provided that the P/L learning process is interrupted. The P/L learning unit then resumes the P/L learning process provided that the purge learning process is completed.
