Abstract: An anomaly determination device executes a first anomaly determination process and a second anomaly determination process. The anomaly determination device determines in the first anomaly determination process that an anomaly is present in a link mechanism when a fully-closed-time detection value is outside a closed-side normal range and when a fully-open-time detection value is outside an open-side normal range. The anomaly determination device determines in the second anomaly determination process that an anomaly is present in the link mechanism if the difference between the fully-closed-time detection value and the fully-open-time detection value is outside a normal distance range set in advance when it is not determined in the first anomaly determination process that an anomaly is present in the link mechanism.

Abstract: A drain plug includes a main body which has an entirely threaded region and a partially threaded region. An outer circumferential surface of the main body has an external thread, and at least one cutout. Thus, the entirely threaded region is formed on a base end side of the main body. The cutout includes a first part extending from the leading end of the main body in the axial direction of the main body, and a second part extending from the first part in a direction toward the base end of the main body. The second part has an inclined surface, and the inclined surface is connected to the entirely threaded region.

Abstract: In an internal combustion engine an air-fuel ratio is switched between at least two target values without generating torque fluctuations, while a deterioration in fuel consumption performance and exhaust performance is suppressed. When a condition for switching a combustion mode from stoichiometric combustion to lean combustion and a condition that the amount of change in a target torque is less than or equal to a predetermined value are satisfied, a target EGR rate is increased towards an EGR limit prior to switching the target air-fuel ratio. The target air-fuel ratio is maintained at the stoichiometric air-fuel ratio until the target EGR rate reaches the EGR limit, and in response to the target EGR rate reaching the EGR limit, the target air-fuel ratio is changed towards a lean air-fuel ratio.

Abstract: An internal combustion engine controller is applied to an internal combustion engine incorporating a turbocharger. The engine includes an intake passage, a compressor arranged in the intake passage, a bypass passage connecting portions of the intake passage at upstream and downstream sides of the compressor. An air bypass valve adjusts a flowrate of intake air passing through the bypass passage. The internal combustion engine controller includes an acceleration determination unit and an ABV control unit. The acceleration determination unit is configured to detect an acceleration request sent to the internal combustion engine and determine whether or not the acceleration request is in an initial stage. The ABV control unit is configured to execute a temporary open/close control to open the air bypass valve for a specified period when determined by the acceleration determination unit that the acceleration request is in the initial stage.

Abstract: A target air amount for achieving a requested torque is calculated from the requested torque by using a virtual air-fuel ratio. The virtual air-fuel ratio is changed from a first air-fuel ratio to a second air-fuel ratio in response to a condition for switching an operation mode from an operation by the first air-fuel ratio to an operation by the second air-fuel ratio being satisfied. After the virtual air-fuel ratio is changed from the first air-fuel ratio to the second air-fuel ratio, a target air-fuel ratio is switched from the first air-fuel ratio to the second air-fuel ratio. After the virtual air-fuel ratio is changed from the first air-fuel ratio to the second air-fuel ratio, a target valve timing is switched from a first valve timing to a second valve timing.

Abstract: A time point t0 represents a time point when a turbocharged engine is brought into a decelerating state, and an opening degree of a throttle valve is decreased. A time point t1 represents a time point when an opening command to an ABV is issued. When the ABV has an abnormality, and when a WGV is stuck open, a turbocharging pressure before the time point t0 shows a tendency to fall below a target turbocharging pressure, and a turbocharging pressure after the time point t1 reduces slowly to approach a predetermined pressure. When the WGV is stuck closed, a turbocharging pressure before the time point t0 shows a tendency to exceed the target turbocharging pressure, and the turbocharging pressure after the time point t1 reduces with vigor to approach the predetermined pressure.

Abstract: In an internal combustion engine provided with a turbocharger, a throttle valve, and an actuator, if there is a request for switching from stoichiometric combustion to lean combustion and also there is a request for raising a supercharging pressure after the switching of combustion to a pressure higher than the supercharging pressure before the switching of combustion, the supercharging pressure reserve control for raising the supercharging pressure while a requested intake air amount S required for realizing a requested torque of the internal combustion engine in the stoichiometric combustion is maintained is executed by using the throttle valve and the actuator. After the supercharging pressure reserve control is finished, the switching of combustion is executed. When an actual supercharging pressure reaches the lower of a requested supercharging pressure L and a realizable supercharging pressure, the supercharging pressure reserve control is finished.

Abstract: A target air amount for achieving a requested torque is back-calculated from the requested torque using a virtual air-fuel ratio. The virtual air-fuel ratio is changed from a first air-fuel ratio to a second air-fuel ratio in response to a condition for switching an operation mode from operation in the first air-fuel ratio to operation in the second air-fuel ratio being satisfied. After the virtual air-fuel ratio is changed from the first air-fuel ratio to the second air-fuel ratio, an interval of time passes and the target air-fuel ratio is then switched from the first air-fuel ratio to a third air-fuel ratio that is an intermediate air-fuel ratio between the first air-fuel ratio and the second air-fuel ratio. The target air-fuel ratio is temporarily held at the third air-fuel ratio, and is thereafter switched from the third air-fuel ratio to the second air-fuel ratio.
