20100180658 | CRANKSHAFT PRODUCTION METHOD AND PRODUCTION APPARATUS - A crankshaft production method includes: pressurizing both end portions of a shaft blank with a pressurization surface of a die, the pressurization surface being inclined in a specific direction so as to come close to the other end side of the shaft blank, and applying an axial compressive load to the shaft blank, while restricting a radial deformation in a predetermined zone of the shaft blank in a direction other than the specific direction, thereby swaging the shaft blank and causing the predetermined zone to buckle in the specific direction. | 07-22-2010 |

20140119907 | TURBINE HOUSING AND EXHAUST GAS TURBINE SUPERCHARGER - A turbine housing includes an outer housing member, which has a proximal housing portion and a distal housing portion, and an inner housing member, which is provided inside the outer housing member and has a shroud surface that faces a turbine wheel in an axial direction. A distal portion of the inner housing member serves as a slide portion slidable in the axial direction. Further, a proximal portion of the inner housing member is fixed to the proximal housing portion at a part closer to a distal side than a proximal portion of the proximal housing portion. Further, a scroll portion is formed by the inner housing member and a proximal scroll portion of the proximal housing portion located closer to a proximal side than the inner housing member. | 05-01-2014 |
20140305108 | EXHAUST GAS EVACUATION SYSTEM STRUCTURE FOR INTERNAL COMBUSTION ENGINE - An exhaust system structure for an internal combustion engine is provided with an exhaust manifold and a plate-like heat shielding member. The exhaust manifold has branch pipes and flanges formed at the distal ends of the branch pipes. The heat shielding member covers the exhaust manifold and suppresses the occurrence of heat damage caused by the exhaust manifold. The basal portion of the heat shielding member and the flanges are fastened to the cylinder head by common fastening members. | 10-16-2014 |
20150020783 | INTERNAL COMBUSTION ENGINE - A second recirculation passage recirculates blow-by gas at an upstream section, which is upstream of an impeller of a turbocharger in an intake passage. A first passage branches and extends from a downstream section, which is downstream of the impeller in the intake passage. A second passage that forms part of the second recirculation passage connects the first passage and the upstream section to each other. A third passage, which is provided separately from the second passage, connects the first passage and the upstream section to each other. A change mechanism changes, in different manners, the flow rate of compressed gas recirculating to the upstream section through the second passage, and the flow rate of compressed gas recirculating to the upstream section through the third passage. | 01-22-2015 |
20150292562 | BEARING STRUCTURE FOR TURBOCHARGER - A bearing structure for a turbocharger includes a center housing, which is arranged between a turbine wheel and a compressor wheel and has an insertion hole, a rotary shaft, which is inserted through the insertion hole and couples the turbine wheel to the compressor wheel, a pair of bearing members, which is press-fitted into the gap between the rotary shaft and the center housing and rotationally supports the rotary shaft, and a restriction member, which is held by the rotary shaft at a position between the bearing members and restricts the movement of the rotary shaft in the thrust direction by engaging with the bearing members. The bearing members have engagement surfaces engaging with the restriction member. An oil supply opening is formed in each of the engagement surfaces. | 10-15-2015 |
20150300202 | TURBOCHARGER - A turbocharger includes a turbine housing, a compressor housing, and a bearing housing. Each of the housings includes a passage for cooling inside. The turbocharger further includes a switching valve and a controller that switches a valve position of the switching valve. The switching valve is adapted to switch the circulation state of coolant in each passage such that the coolant is supplied from the passage of the turbine housing to the passage of the bearing housing or such that the coolant is supplied from another passage to the passage of the bearing housing. The controller switches the valve position of the switching valve such that the coolant is supplied from the passage of the turbine housing to the passage of the bearing housing until a predetermined amount of time passes after starting of the engine. | 10-22-2015 |
