  • Patent number: 11300080
    Abstract: A dual chamber fuel tank protector valve has a transversely oriented divider defining a plurality of apertures for fluid flow between a first port and a second port. Each chamber has a seal disk therein. The first seal disk is normally biased to an open position by a first biasing member. The second seal disk is normally biased to a closed position by a second biasing member having a preselected biasing force set to a preselected pressure differential that allows movement to its open position before the first seal disk moves to its closed position. When the first seal disk and the second seal disk move to their respective closed positions, the direction of movement is toward one another.

  • Patent number: 10590889
    Abstract: A canister that is mounted on a vehicle includes an inflow port, an outflow port, an atmosphere port, a valve, at least one honeycomb body, and a spacer. The inflow port is coupled to a fuel tank in the vehicle. The outflow port is coupled to an intake flow passage of an internal combustion engine in the vehicle. The atmosphere port communicates an interior of the canister with an exterior of the canister. The valve opens and closes the atmosphere port. The honeycomb body is arranged in the most downstream side in a gas flow passage that leads to the atmosphere port from the inflow port, which is the upstream of the valve, enables adsorption and desorption of an evaporated fuel evaporated from the fuel tank, and has a honeycomb configuration. The spacer is arranged between the valve and the honeycomb body and maintains a specific distance therebetween.

  • Patent number: 10584663
    Abstract: An engine off natural vacuum (EONV) evaporative fuel leak check system includes a fuel tank, a heat exchanger, an air duct, a fan, a fuel temperature sensor, and a controller. The fan directs air onto the heat exchanger, and the heat exchanger heats air passing around the heat exchanger in a heat exchange process using heat from engine coolant within the heat exchanger. The air duct extends between the fuel tank and the heat exchanger and the fan moves the heated air through the air duct toward the fuel tank. The controller is configured to control the fan for moving the heated air toward the fuel tank based on a temperature of the fuel within the fuel tank, as detected by the fuel temperature sensor.

  • Patent number: 10549629
    Abstract: Disclosed is a method for controlling depressurization in a fuel tank of a motor vehicle, including: the initial controlled opening of the isolation valve in order to lower the pressure inside the tank; determination of a blockage condition in the roll over valve on the basis of at least one item of information relating to the pressure gradient in the tank following the initial opening of the isolation valve; and, if the roll over valve blockage condition is met, the controlled closing of the isolation valve, followed by its controlled re-opening in order to continue lowering the pressure in the tank.

  • Patent number: 10526984
    Abstract: A fuel evaporative emission control device including an electronic control unit that, when fuel tank inner pressure exceeds a first predetermined pressure, performs tank purge of closing a bypass valve and opening a sealing valve, discharging fuel evaporative gas inside the fuel tank into an air intake path of an engine in an operated state through a purge pipe and a vapor pipe, and treating the fuel evaporative gas, where, when tank purge is performed, if a first predetermined period of time passes after closing of the bypass valve without the fuel tank inner pressure falling to or below the first predetermined pressure, the sealing valve is closed and tank purge is stopped.

  • Patent number: 10480431
    Abstract: Methods and systems are provided for indicating a presence or absence of degradation in a vehicle evaporative emissions system, where degradation includes a restriction in the evaporative emissions system and/or a source of undesired evaporative emissions. In one example, a method includes, under conditions where an engine is not combusting air and fuel, applying a pressure from the evaporative emissions system to an intake of the engine, and indicating an absence of degradation in the evaporative emissions system based on a test flow in the intake of the engine being within a predetermined threshold of a baseline flow obtained at an earlier time via applying the pressure. In this way, a presence or absence of degradation may be indicated without relying on engine operation.

  • Patent number: 10480458
    Abstract: A device having activated carbon canisters. A fuel tank used to supply fuel is vented into the activated carbon canisters that have, as activated carbon filters, carbon granules having large surfaces for temporarily adsorbing the hydrocarbon gases contained in the fuel tank emissions. The regeneration occurs cyclically by backflushing where fresh air is sucked in through an outlet and conducted through the activated carbon canisters to lead the hydrocarbon gases back into the region of the combustion apparatus. The device has structurally identical activated carbon canisters arranged in the same plane and connected in series by connecting lines, whereby an outlet opening of a first activated carbon canister is connected to an inlet opening of a further activated carbon canister. The outlet opening of the activated carbon canister is arranged above the inlet opening with respect to gravity.
