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 vehicular propulsion system, a vehicular fuel system and a method of operating an internal combustion engine. A separation unit that makes up a part of the fuel system includes one or more adsorbent-based chambers such that the separation unit may selectively receive and separate at least a portion of onboard fuel into octane-enhanced and cetane-enhanced fuel components. A supply tank includes three compartments where the first contains the onboard fuel, the second receives a vaporized adsorbate from the separation unit and condenses at least a part of it into one of an octane-rich fuel component or a cetane-rich fuel component, while the third may either store the condensed and enriched fuel component or help condense more of the vaporized adsorbate. The condensing takes place through heat exchange between the onboard fuel and the vaporized adsorbate that are present within the various compartments of the supply tank. A controller may be used to determine a particular operational condition of the internal combustion engine such that the onboard fuel can be sent to one or more combustion chambers within the internal combustion engine without first passing through the separation unit, or instead to the separation unit in situations where the internal combustion engine may require an octane-rich or cetane-rich mixture.

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.

Abstract: Introduction of a low fuel consumption technique such as downsizing turbos and idling stop decreases an intake pipe negative pressure (pump loss) of an internal combustion engine, and results in difficulty in emitting (evaporative fuel purge) a volatile fuel (volatile fuel) in a fuel tank by the negative pressure of the intake pipe of the internal combustion engine. A control device includes: a purge control unit which controls a purge valve which emits a volatile fuel of a fuel tank or a canister to an intake pipe of an internal combustion engine; and a power transmission control unit which controls a power transmission mechanism between the internal combustion engine and a drive wheel, and, in a state where the power transmission control unit disconnects a clutch, and the vehicle is coasting, the purge control unit opens the evaporative fuel valve and purges an evaporative fuel to the intake pipe.

Abstract: Disclosed is a method for controlling the pressure inside a fuel tank of a motor vehicle, the motor vehicle including a fuel vapor vent circuit connecting the tank to a fuel vapor canister, the vent circuit including an isolation valve for isolating the tank and a rollover valve. The pressure control method includes steps of: determining an activation duration required for the isolation valve to transition from a closed state to a fully open state, referred to as the “full opening duration”, when a predefined rollover valve closure risk criterion is satisfied: controlling the isolation valve in repeated activations of respective durations that are shorter than the full opening duration.

Abstract: A system for combusting volatile vapors includes a carburetor having intake valves for receiving base fuel from a fuel source, ambient combustion air, and volatile vapors from a vapor source. A plurality of sensors measure and generate sensor data based on a respective plurality of physical properties associated with the carburetor and associate combustion engine operation. One or more programmable controllers receive the sensor data and control the intake valves to regulate respective ratios of the fuel, air, volatile vapors drawn through the carburetor based on the received sensor data. To increase the burn of volatile vapors, an engine loading system automatically operated by the controller(s) applies an automatically adjustable braking load on the engine. The load level applied is based on the sensor data and commensurate with maintaining stable engine running conditions. The loading system decreases time necessary to remediate a site.

Abstract: Methods and systems are provided for conducting a refueling operation. In one example, during the refueling event, fuel vapors may be routed from a fuel tank to a first fuel vapor canister, and upon indication that the first fuel vapor canister is saturated with hydrocarbons, fuel vapors may be routed from the fuel tank to a second fuel vapor canister thus bypassing the first fuel vapor canister, without input from a powertrain control module. In this way, during refueling, saturated fuel vapor canisters are bypassed such that resistance to fuel vapor flow may be decreased, thus reducing the likelihood of premature shutoffs of a refueling dispenser.

Abstract: Methods and systems are provided for periodically activating a vehicle engine such that issues that may occur responsive to engine inactivity, such as rust and the sticking of components of the valve train, may be prevented. In one example, a vehicle engine increment off timer is used to monitor a duration wherein the vehicle engine has not been active, and responsive to expiration of the timer, spinning the engine unfueled in reverse while concurrently activating an onboard pump to direct air and fuel vapor to be stored in a fuel vapor canister. In this way, periodic engine lubrication operations may be conducted that do not require the use of fueled engine operation, thereby improving fuel economy and reducing undesired evaporative emissions.
