  • Publication number: 20180264937
    Abstract: An evaporated fuel treatment device executes a pressure reducing control while monitoring inner pressure of a fuel tank, so that when the inner pressure of the fuel tank exceeds a predetermined value prior to fueling to the fuel tank, pressure reduction progresses within a range that the flow rate of a vapor passage does not exceed the boundary flow rate where the vapor passage is closed by a valve element of an ORVR valve, and also a valve opening speed of the closing valve is made higher as the inner pressure of the fuel tank becomes lower.

  • Publication number: 20180171894
    Abstract: An evaporated fuel processing apparatus is provided with a blocking valve disposed in a vapor passage. The blocking valve has: a valve whose stroke amount is adjusted by a stepping motor; and a relief valve being opened regardless of the stroke amount when tank pressure of a fuel tank is greater than or equal to a predetermined pressure to allow communication between the fuel tank and a canister. The evaporated fuel processing apparatus is provided with a controller configured (i) to control the stepping motor to move the valve in a valve opening direction while prohibiting a valve opening position learning process when the tank pressure is greater than or equal to the predetermined pressure and (ii) to allow the valve opening position learning process when the tank pressure is less than the predetermined pressure.

  • Patent number: 9764731
    Abstract: During deceleration with operation of an engine, an amount of wall surface deposition is estimated to tend to increase with a decrease in corrected operation time that is based on an operation time of the engine. A target amount of fuel injection is set by adding a correction value that is set according to a variation in the amount of wall surface deposition to a base amount of fuel injection. Fuel injection control of the engine is performed by using the set target amount of fuel injection.

  • Patent number: 9759150
    Abstract: On start of an engine, a difference ?Pm 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 ?Pm is equal to or less than a reference value ?Pmref continues over a predetermined number of strokes nref of the engine.

  • Patent number: 9428180
    Abstract: 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.

  • Publication number: 20160160775
    Abstract: When a conversion catalyst in a catalytic converter is warmed up, a required efficiency ?tag is set such as to be within a range of less than 1 that is a value when the conversion catalyst is not warmed up and to increase with an increase in delay of an open-close timing VT of an intake valve (steps S130 to S160). A delayed amount of a target ignition timing IT* is decreased with an increase in required efficiency ?tag (closer to the value 1) (steps S170 and S180).
