  • Patent number: 10928276
    Abstract: A blockage detection device opens a purge valve in a state where a negative pressure pump is operated. The negative pressure pump is connected to a downstream side of a canister with respect to a fuel tank, and reduces pressure in a device internal space. The blockage detection device calculates gas information (volume V, for example) of the device internal space on the basis of variation of internal pressure before and after the purge valve is opened. The blockage detection device detects a blockage in a vent line using the calculated gas information.

  • Patent number: 10712228
    Abstract: A blockage diagnosis device includes a diagnosis unit that performs blockage diagnosis on a vent passage based on a change over time in an internal pressure of the vent passage in association with the operation of a negative pressure pump. A primary determination unit of the diagnosis unit makes a primary determination that the vent passage is blocked, if a first estimation volume V1 is less than a preset threshold volume Vth. A secondary determination unit of the diagnosis unit makes a secondary determination that the vent passage is blocked, if the second estimation volume V2 is less than the threshold volume Vth. If the primary determination indicating that the vent passage is blocked is made in the primary determination unit, and the secondary determination indicating that the vent passage is blocked is made in the secondary determination unit, the diagnosis unit determines that the vent passage is blocked.
