    Abstract: The application discloses a carbon canister assembly and an engine, which relates to the technical field of auto parts. A carbon canister assembly comprises a main carbon canister and an auxiliary carbon canister; The main carbon canister has a first cavity, the first cavity is cylindrical, and the first cavity is filled with adsorption material for adsorbing evaporated fuel vapor; The auxiliary carbon canister has a second cavity communicated with the first cavity, the second cavity is in a round table shape, and the diameter of the cross section of the second cavity in a round table shape gradually decreases from bottom to top. An engine comprises the carbon canister assembly. The application can solve the problem that the oil and gas molecules in the carbon powder in the dead corner section area of the cross section of the carbon bed are not easy to be swept away by air, which is helpful to reduce the cost, ensure the adsorption effect and reduce the failure rate.

    Abstract: An evaporated fuel processing device may include: a canister that communicates with a fuel tank though a tank passage, communicates with an intake passage of an engine through a purge passage, and communicates with open air through an open air passage; a control valve that switches between a closed state of closing the purge passage and an open state of opening the same; a pump that changes a pressure in a communicating space in a case where the control valve is in the closed state, the communicating space defined by the fuel tank, the tank passage, the canister, the open air passage, and the purge passage on a side closer to the canister relative to the control valve; a pressure detector disposed in the communicating space; and a determining unit that determines the evaporated fuel processing device is not operating normally by using a pressure detection result by the pressure detector in a state where the control valve is in the closed state and the pressure in the communicating space is changed by the pump.

    Abstract: A fuel vapor processing apparatus form an internal combustion engine provided with a turbocharger includes a canister and an ejector. The canister is configured to adsorb fuel vapor from a fuel tank. The ejector is configured to generate a negative pressure by supercharged air flowing from an intake passage on a downstream side of the turbocharger to the intake passage on an upstream side of the turbocharger, so that fuel vapor in the canister is purged by the negative pressure. The ejector includes an ejector housing extending in a discharge direction of the supercharged air. The ejector housing is welded to a tubular member defining a passage wall of the intake passage such that the supercharged air is discharged into the intake passage on the upstream side of the turbocharger and that the discharge direction of the supercharged air is parallel to a direction of flow of intake air.
