摘要： A controller for an internal combustion engine, a control method for an internal combustion engine, and a memory medium are provided. The controller executes a deactivation process that deactivates combustion control in a specified one of cylinders. A compensation process operates a power generation device that produces driving torque applied to a driven wheel so as to compensate for insufficiency of the driving torque of a vehicle caused by the deactivation process. A prohibition process prohibits the deactivation process when it is determined that compensation by a predetermined amount or larger by the compensation process cannot be performed.

摘要： A controller for an internal combustion engine, a control method for an internal combustion engine, and a memory medium are provided. The controller determines whether an execution request of a temperature-increasing process for an aftertreatment device for exhaust gas has been issued. When the execution request is determined as having been issued, supply of fuel by a fuel injection valve corresponding to a specified cylinder is deactivated. The specified cylinder is one of cylinders. An air-fuel ratio of air-fuel mixture in a cylinder of the cylinders that differs from the specified cylinder is set to be richer than a stoichiometric air-fuel ratio. When the temperature-increasing process is executed, an adjustment device is operated so as to reduce the fuel concentration in an intake port connected to the specified cylinder.

摘要： A vehicle includes an engine and an electric power output device that is configured to output electric power generated by using the engine to the outside of the vehicle. The engine includes an EGR device for recirculating exhaust gas of the engine to an intake side. The vehicle further includes a controller for controlling a recirculation amount of the exhaust gas by the EGR device in accordance with a load of the engine. The controller restricts the recirculation amount of the exhaust gas under the same load in the case where the electric power output device outputs the electric power to the outside of the vehicle in comparison with a case where the electric power output device does not output the electric power to the outside of the vehicle.

摘要： When a rotational fluctuation ΔNEeng of an engine is equal to or larger than a first threshold NEref1, a rotational fluctuation ΔNEmg1 of a motor MG1 that is calculated at a timing preceding the rotational fluctuation ΔNEeng of the engine by 180 degrees in terms of a rotational angle of a crankshaft is compared with a second threshold NEref2. When the rotational fluctuation ΔNEmg1 is equal to or larger than the second threshold NEref2, it is determined that the rotational fluctuation ΔNEeng of the engine has reached a value equal to or larger than a threshold NEref due to a disturbance such as running on a bad road or the like, and a misfire counter is maintained. When the rotational fluctuation ΔNEmg1 is smaller than the second threshold NEref2, it is determined that a misfire may be occurring in at least one of cylinders of the engine, and the misfire counter is incremented.

摘要： An ECU performs a failure diagnosis for a thermostat valve after starting of an engine based on an output of an engine-side coolant water temperature sensor and an output of a radiator-side coolant water temperature sensor. When an electric pump operates in accordance with a heating request or the like of an air-conditioning device during stopping of the engine, the thermostat valve attains a closed state. When the electric pump operates during stopping of the engine before the current starting of the engine, starting of the failure diagnosis performed after starting of the engine is delayed as compared to the case where the electric pump does not operate during stopping of the engine. Consequently, erroneous determination can be suppressed in the failure diagnosis for the thermostat valve.

摘要： A controller for a hybrid electric vehicle includes an engine ECU and a HEVECU. The engine ECU executes a partial cylinder fuel cut-off control that stops supply of fuel to one or more cylinders and supplies fuel to the remaining ones of the cylinders. Further, the engine ECU sends control information of the partial cylinder fuel cut-off control to the HEVECU. The HEVECU executes a driving force compensation control so as to compensate for, using driving force of a motor generator, a decrease in driving force of a multi-cylinder engine that results from the execution of the partial cylinder fuel cut-off control. The engine ECU prohibits the execution of the partial cylinder fuel cut-off control when an anomaly possibly occurs in the sending and receiving of the control information of the partial cylinder fuel cut-off control.

摘要： If an engine coolant temperature is equal to or lower than a first low-temperature determination value and a battery temperature is equal to or lower than a second low-temperature determination value when a request to start up an engine is made, the advancement driving of a variable valve operating mechanism is first started. Then, when an advancement amount of the variable valve operating mechanism later becomes equal to or larger than a prescribed startup start determination value, is started.

摘要： A CPU determines that there is a misfire when a relative magnitude of a rotation fluctuation amount ΔT30[0] related to a cylinder subject to the determination in relation to a rotation fluctuation amounts ΔT30[4] of the previous combustion cycle is greater than or equal to the determination value Δth. However, during the execution of a catalyst warm-up process, the CPU uses, in the comparison, the relative magnitude of the rotation fluctuation amount ΔT30[0] in relation to the average ΔT30ave[0] of the smallest five of the rotation fluctuation amounts ΔT30[4] to ΔT30[40] from the past ten combustion cycles.

摘要： A hybrid vehicle controller includes processing circuitry configured to execute a particulate matter (PM) deposition amount estimation process that estimates a deposition amount of PM deposited in the filter. The processing circuitry is configured to switch between a first mode and a second mode as a control mode that defines control of the engine and the motor. A use of the engine is limited in the first mode as compared with the second mode. The processing circuitry is configured to execute a display process that notifies a user that the filter needs to be regenerated when the control mode is the second mode if the estimated deposition amount is greater than or equal to a predetermined amount, and not to execute the display process when the control mode is the first mode even if the deposition amount is greater than or equal to the predetermined amount.
