摘要： An upstream integrated value is an integrated value of a difference obtained by subtracting an upstream gas temperature at a starting point in time of integration from the upstream gas temperature after starting of the internal combustion engine. A downstream integrated value is an integrated value of a difference obtained by subtracting a downstream gas temperature at the starting point in time of the integration from the downstream gas temperature after the starting of the internal combustion engine. An anomaly diagnosing process obtains an anomaly determination result indicating that the exhaust purification device is in a removed state when a deviation between the upstream integrated value and the downstream integrated value is smaller than a reference level. The determination threshold is higher than a dew point.

摘要： A first condition is set to such a condition of a fuel injection amount of a fuel injection valve and an opening degree of a throttle valve that an air excess ratio in a cylinder becomes greater than or equal to a prescribed value set as a value greater than 1.2 while satisfying a target output of an internal combustion engine. A second condition is set to such a condition of the fuel injection amount and the opening degree of the throttle valve that the air excess ratio in the cylinder becomes 1 or less while satisfying the target output of the internal combustion engine. A controller of the internal combustion engine is configured to obtain the first and second operating conditions that correspond to the target output, and select one of the operating conditions in accordance with the operating situation of the internal combustion engine.

摘要： A vaporized fuel treatment device includes a sealing valve disposed in a vapor passage between a fuel tank and a canister and is configured to include a valve element moves forward and backward in an axial direction to a valve seat, a cut-off valve configured to cut off a communication between the canister and an atmosphere, a tank internal pressure sensor detects an internal pressure of the fuel tank, and a canister internal pressure sensor that detects an internal pressure of the canister, a controller programmed to change an axial distance between the valve element and the valve seat in a state where the cut-off valve cuts off the communication between the canister and the atmosphere and to learn a valve opening start position of the sealing valve based on changes in the internal pressures of the fuel tank and the canister depending on a change in the axial distance.

摘要： On start of an engine, a difference ΔPm between a first intake pipe pressure Pm1 and a second intake pipe pressure Pm2 is computed. Reduction correction of wall surface deposition correction is prohibited until the state that the difference ΔPm is equal to or less than a reference value ΔPmref continues over a predetermined number of strokes nref of the engine. After the state that the difference ΔPm is equal to or less than the reference value ΔPmref continues over the predetermined number of strokes nref of the engine, permission is given for the reduction correction.

摘要： A failure diagnosis apparatus comprises a controller that is configured to execute a failure diagnosis process of the internal combustion engine based on a predetermined diagnosis requirement. The diagnosis requirement in a case where engine-operation-electric-power supply is executed is made different from the diagnosis requirement in a case where engine-normal-operation is executed such that a failure of the internal combustion engine in the case where the engine-operation-electric-power supply is executed is less likely to be detected or the failure of the internal combustion engine is less likely to be recognized by a driver than in the case where the engine-normal operation is executed.

摘要： An information processing device includes a control unit. The control unit executes determination processing to determine whether or not a user will arrive at a first shop by a first time that is set based on a reservation start time of the first shop. When the control unit determines that the user will not arrive at the first shop by the first time, the control unit determines a cancellation fee based on movement information on the user.
