  • Patent number: 12071908
    Abstract: 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.

  • Patent number: 10954895
    Abstract: The evaporated fuel treatment device includes: a canister that adsorbs evaporated fuel generated within a fuel tank that is provided to a vehicle; a vapor passage that connects the canister and the fuel tank; a shutoff valve capable of closing off and opening up the vapor passage. When a specific event by which a current position of the shutoff valve becomes unknown occurs and initialization processing has become necessary, a first process is performed in which the shutoff valve is operated by a first operating amount that is set as an operating amount capable of operating the shutoff valve to an operation limit, irrespective of the current position, while, when the initialization processing has become necessary without the specific event occurring, a second process is performed in which the shutoff valve is operated by a second operating amount that is an operating amount from the current position to an initial position, and that is smaller than the first operating amount.

  • Patent number: 10851722
    Abstract: Both an improvement in detection accuracy of a valve opening position of a blocking valve and a reduction in time required for learning of the valve opening position are achieved. An evaporated fuel processing apparatus is provided with a learning device configured to learn the valve opening position of the blocking valve. The learning device learns the valve opening position (i) by stepwisely increasing a stroke amount by rotating a stepping motor by two steps at each time in a valve opening direction and (ii) by determining whether a difference between the stroke amount at present and the stroke amount corresponding to the valve opening position is one step of rotation of the stepping motor, or two steps, on the basis of pressure fluctuation on the canister side of the blocking valve associated with the rotation of the stepping motor when the blocking valve is opened, when learning the valve opening position.
