20150232087 | SYSTEM FOR COOLING VEHICLE-MOUNTED POWER CONTROL DEVICE AND METHOD FOR DIAGNOSING ABNORMALITY - A system for cooling a power control device of a hybrid vehicle includes a cooling device for cooling a power control device, an electronic control device for controlling the cooling device, and an intake temperature sensor. The electronic control device determine whether the vehicle is in a reference traveling state with an intake amount ensured to be greater than or equal to a reference intake amount. When determining that the vehicle is in the reference traveling state, the control device determines presence or absence of abnormality in the cooling device using an intake temperature detected by the intake temperature sensor. When determining that the vehicle is not in the reference traveling state, the control device refrains from determining presence or absence of abnormality in the cooling device. | 08-20-2015 |
20150267708 | COOLING SYSTEM FOR VEHICLE-MOUNTED POWER CONTROL DEVICE AND METHOD FOR DIAGNOSING ABNORMALITY IN COOLING SYSTEM - A cooling system includes a cooling device and an electronic control device for controlling the cooling device. The cooling device has a rotating component for delivering cooling medium and a drive source for controlling the rotating component. The electronic control device stores diagnosis reference information, which indicates an actual rotation speed acceptable range when an actual rotation speed of the drive source is apart from an instructed rotation speed of the drive source. The actual rotation speed acceptable range is an acceptable range of the actual rotation speed. The acceptable range changes according to the instructed rotation speed and a voltage value applied to the drive source. The electronic control device obtains the acceptable range based on the diagnosis reference information to determine whether the cooling device is in a normal state. | 09-24-2015 |

20150110607 | VARIABLE NOZZLE UNIT AND VARIABLE GEOMETRY SYSTEM TURBOCHARGER - An inner surface of each first supporting hole of a shroud ring has on both sides in the axial direction of a turbine impeller two first bearing portions by which first nozzle shaft is rotatably supported. An inner surface of each second supporting hole of a nozzle ring has a second bearing portion by which a second nozzle shaft is rotatably supported. The fitting clearance between the second bearing portion and the second nozzle shaft is set larger than the fitting clearance between each of the first bearing portions and the first nozzle shaft. | 04-23-2015 |
20150122233 | VARIABLE GEOMETRY SYSTEM TURBOCHARGER AND METHOD OF MANUFACTURING HOUSING FOR VARIABLE GEOMETRY SYSTEM TURBOCHARGER - A reservoir groove for storing condensate water is formed on a lower part side of a link chamber inside a turbine housing. The reservoir groove is formed such that, assuming that water vapor contained in an exhaust gas retained inside the link chamber is completely condensed and liquefied after an engine stops its operation, a height position of a reference water surface of the condensate water stored in a reservoir area, which includes a space inside the reservoir groove in the link chamber, is lower than a height position of a lowermost part of the link mechanism. | 05-07-2015 |
20150184541 | BEARING STRUCTURE AND TURBOCHARGER - A shaft includes: two large-diameter portions; and a small-diameter portion formed between the two large-diameter portions. A bearing includes: an annular body in which to insert the shaft; two bearing surfaces being opposite the large-diameter portions; and an intervening surface located between the two bearing surfaces on an inner circumferential surface of the body, and being opposite the small-diameter portion with a clearance formed between the intervening surface and the small-diameter portion. No anti-corrosion treatment is applied to the large-diameter portions. An anti-corrosion treatment is applied to at least any one of: an exposed portion of an outer peripheral surface of the body of the bearing, which is exposed to the outside of the housing; the intervening surface of the bearing; an opposite end surface of the bearing; and the small-diameter portion of the shaft. | 07-02-2015 |
