  • Patent number: 11247577
    Abstract: A vehicle comprising a battery, a power converter, a charger, a first and a second temperature adjustment circuit including a first and a second pumps for supplying a heat medium, a coupling passage which forms a coupling circuit by coupling the first and the second temperature adjustment circuits, a switching unit capable of switching a state between a circulation state and a non-circulation state, and a control device to select one mode from a plurality of modes. The plurality of modes includes a series mode in which the heat medium is circulated in the coupling circuit in the circulation state and a separate mode in which the heat medium is circulated in at least the second temperature adjustment circuit in the non-circulation state. The control device executes the series mode when charging the battery.

  • Publication number: 20200203787
    Abstract: A temperature adjustment circuit includes a first pump that circulates a heat medium in at least one of a first temperature adjustment circuit and a second temperature adjustment circuit; a coupling path that couples the first temperature adjustment circuit and the second temperature adjustment circuit to form a coupled circuit; a switching unit capable of switching between a circulation state in which the heat medium circulates in the coupled circuit and a non-circulation state in which the heat medium does not circulate in the coupled circuit; and a control device that controls the switching unit and the first pump. The control device switches the coupled circuit from the non-circulation state to the circulation state in a state in which a rotation speed of the first pump is decreased lower than a rotation speed of the first pump before switching, and increases the rotation speed of the first pump after switching.

  • Patent number: 10174721
    Abstract: A passage through which a fluid can flow is formed in a canister. A first end of the passage includes an evaporated fuel introducing port and a purge port, and a second end of the passage includes an atmosphere release port. A first chamber and a second chamber are provided at the passage. The first chamber accommodates a first adsorbent, and the second chamber accommodates a second adsorbent, both capable of adsorbing and desorbing evaporated fuel. The passage is horizontal when the canister is mounted on the vehicle. A flow dividing plate including a plurality of communicating holes is provided in the second chamber, close to the atmosphere release port. When the canister is mounted, an area of the communicating holes per unit area on a surface of the flow dividing plate is larger at a lower side of the flow dividing plate than at an upper side.

  • Publication number: 20180274490
    Abstract: Disclosed herein is a canister (1) having a passage therein. One end of the passage is provided with a fuel vapor introduction port (11) and a purge port (12). The other end of the passage is provided with an open-to-air port (13). The passage includes a first chamber (21) and a second chamber (22) sequentially arranged from the one end of the passage. The first and second chambers house first and second adsorbents (51) and (61), respectively, which are capable of adsorbing and desorbing fuel vapor. The canister is configured such that, when mounted on a vehicle, a first passage, of the passage, corresponding to the first chamber is approximately horizontal, and that a second passage, of the passage, corresponding to the second chamber is approximately vertical, with one side of the second passage closer to the open-to-air port being located above the other side of the second passage.

  • Publication number: 20170159588
    Abstract: The invention is a method for operating a fuel vapor processing system. The fuel processing system includes: a purge passage; a canister configured to receive and store therein fuel vapor from a fuel tank; a pressurizer pump; a purge valve; and a pressure sensor configured to detect a pressure in a detection section between said pressurizer pump and said purge valve. The method includes: when determined that said engine is under said specific engine condition, closing said purge valve; operating said pressurizer pump to pump a gas, which contains the fuel vapor stored in said canister, into said detection section; and estimating concentration of the fuel vapor in the gas residing in said detection section based on a signal from said pressure sensor detected after a pressure increase in said detection section, and controlling said purge valve to be further opened as the estimated fuel vapor concentration is lower.

  • Publication number: 20170114764
    Abstract: A fuel injection valve includes a fixed core formed into a cylindrical shape, a valve plunger that can move closer to or away from the fixed core, a retainer formed with a substantially C-shaped cross-section having one long straight opening extending linearly along the entire length in an axial direction while having a tapered face on an outer periphery of each of opposite end parts in the axial direction and is press fitted into the fixed core, and a return spring provided between the retainer and the valve plunger. A cutout is provided in peripherally opposite end parts of the retainer for increasing the width between opposite end parts in a longitudinal direction of the opening. This enables the degree of freedom in selecting the material for forming a retainer while preventing the occurrence of galling or generation of swarf when press fitting the retainer into the fixed core.
