20120304865 | EVAPORATED FUEL TREATING DEVICE - An evaporated fuel treating device lowers the blow-by volume of evaporated fuel emitted to the atmosphere via a casing having an atmospheric port. The casing has in series a first adsorbent chamber housing an adsorbent material, a space chamber not housing an adsorbent material and a second adsorbent chamber housing an adsorbent material. Each of the chambers is positioned beside an adjacent chamber thereof. The first chamber is disposed closest to the atmospheric port among the adsorbent chambers. An end part of the space chamber on a side of the first chamber has a first partition wall having an opening part with a plurality of first openings provided on a top side of the first partition wall. A current plate has one end positioned between the adjacent first openings and a surface and a rear face of the current plate are disposed along the top and bottom direction. | 12-06-2012 |

20120309584 | POWER TRANSMISSION UNIT - After an engine starts, a rotation speed of the engine is fed back to a target rotation speed that is defined in response to requested power for the engine. In addition, by operating a gear ratio of a CVT, a rotation speed of an output side of a one-way bearing is fed back to the target rotation speed. | 12-06-2012 |
20140136086 | VEHICLE CONTROLLER - A vehicle controller performs a throttle-valve-late-close control in which the throttle valve is held open until a delay time has passed after the fuel cut is started, and an EGR-valve-open-close control in which the EGR valve is repeatedly opened and closed. Then, the throttle valve is closed and the EGR valve is opened. In a period from a latter period of an exhaust stroke to a preceding period of an intake stroke, a valve-overlap control is executed so that a variable valve timing controller is controlled to make both an intake valve and an exhaust valve opened. A pumping loss of an engine is sufficiently reduced and an energy-regenerate efficiency can be effectively improved. | 05-15-2014 |
20150051775 | VEHICLE CONTROL APPARATUS - A vehicle control apparatus uses a travel mode selection unit to select between an EV travel mode, an engine travel mode, and an engine generation mode depending on comparisons between an engine generated power cost, an EV effect, and a surplus electric energy. In such manner, according to a travel condition of a vehicle, an appropriate travel mode is selected for an improvement of fuel consumption efficiency. The vehicle control apparatus also computes a fuel consumption decrease or a fuel consumption increase for each of a plurality of travel modes based on an engine efficiency and an MG-INV efficiency. In such manner, fuel consumption increase/decrease for every travel mode may be computed. | 02-19-2015 |
20150051776 | VEHICLE CONTROL APPARATUS - A vehicle control apparatus computes a fuel consumption decrease or a fuel consumption increase for each of a plurality of travel modes. The vehicle control apparatus includes a control section that calculates an engine efficiency of an engine and an MG-INV efficiency which is a combined efficiency of a motor generator and an inverter. The engine efficiency is calculated based on an engine power and an ideal fuel consumption line. The MG-INV efficiency is calculated based on an MG power. As such, based on the engine efficiency and the MG-INV efficiency, the control section computes the per-unit-electric-power fuel consumption decrease or the per-unit-electric-power fuel consumption increase. | 02-19-2015 |

20130019963 | FUEL CUT-OFF VALVE ASSEMBLIES - A fuel cut-off valve assembly may include a housing disposed within a fuel tank and defining therein a float chamber communicating with a space defined in the fuel tank. The housing has a fuel vapor outlet hole, so that fuel vapor can flow from within the float chamber to a fuel vapor processing device. A float valve may be received within the float chamber so as to be vertically movable for opening and closing the fuel vapor outlet hole in response to change in a level of fuel within the fuel tank. The float valve may have a valve body and a buoyancy center positioned at a level higher than a central position of the valve body with respect to the height of the valve body. | 01-24-2013 |
