摘要： 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.

摘要： An exhaust purification device includes a PM filter and a differential pressure sensor for the PM filter, and calculates a first estimated amount PMf based on the operating state of the internal combustion engine and a second estimated amount PMc based on the differential pressure. 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.

摘要： 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.

摘要： The air-fuel ratio feedback control section updates an air-fuel ratio feedback correction value. The air-fuel ratio learning control section performs, in each of learning regions, learning of an air-fuel ratio learning value. If the air-fuel ratio feedback correction value converges to a value less than or equal to a specified value, the air-fuel ratio learning control section determines that learning of the air-fuel ratio learning value in the learning region has been completed. If it has not yet been determined that learning of the air-fuel ratio learning value has been completed in any of the learning regions, the air-fuel ratio learning control section collectively updates the air-fuel ratio learning values of all the learning regions at the time of updating the air-fuel ratio learning value through learning in any of the learning regions.

摘要： A fuel injection control device learns a port injection learning value and a direct injection learning value separately for each of learning regions that are divided according to the engine operating state. It is assumed that a port injection learning condition and a direct injection learning condition are both satisfied in a learning region in which neither the learning of the port injection learning value nor the learning of the direct injection learning value has been completed. In such a situation, the fuel injection control device executes the port injection learning process if the ratio of the port injection amount is less than the ratio of the direct injection amount, and executes the direct injection learning process if the ratio of the direct injection amount is less than the ratio of the port injection amount.

摘要： An air-fuel ratio controller of an internal combustion engine includes an open-loop processor setting a base injection amount, a feedback processor calculating a feedback operation amount, an increase processor performing an increase correction on the base injection amount when a temperature of the internal combustion engine is a specified temperature or lower, an operation processor operating a fuel injection valve based on the corrected base injection amount and that is corrected using the feedback operation amount and a learning value, and an update processor updating the learning value. If the increase processor performs the increase correction, the update processor updates the learning value to increase an increase correction rate of the base injection amount when a temperature of the cylinder wall surface is high.
