| 20120011955 | TRANSMISSION SHIFT FORK - A transmission shift fork engages with a coupling sleeve of a synchronizer and shifting the coupling sleeve. The transmission shift fork includes a first part, second part, and at least one fin. The first part is arranged to movably mount the transmission shift fork in a shift fork movement direction. The second part includes a coupling sleeve facing surface, an outwardly facing surface, and a pair of shift-direction facing surfaces. The coupling sleeve facing surface includes at least one coupling sleeve engagement part arranged to engage with an engaging groove formed on an external circumferential surface of the coupling sleeve. The outwardly facing surface includes an oil catch disposed in a position with respect to the coupling sleeve engagement part such that the oil catch captures lubricating oil and supplies to the coupling sleeve engagement part. The fin projects from inside an oil receiving recess defined by the oil catch. | 01-19-2012 |
| 20100243191 | CYLINDER BLOCK MANUFACTURING METHOD, DUMMY CYLINDER LINER, AND DUMMY CYLINDER LINER CASTING METHOD - In a cylinder block manufacturing method, first and second dies and a liner support are provided to form a liner overcast configuration. The first and second dies are positioned with respect to the liner support and a dummy cylinder liner made of an aluminum alloy such that the first die contacts a pressing section of a first axial end of the liner support and a first axially facing end of the dummy cylinder liner, and the second die contacts a second axial end of the liner support and a second axially facing end of the dummy cylinder liner. The first and second dies are preheated to a prescribed temperature with the dummy cylinder liner positioned on the liner support by injecting molten aluminum alloy into a cylinder block molding cavity to form a dummy cylinder block with the dummy cylinder liner casted in the dummy cylinder block. | 09-30-2010 |
| 20100242917 | FUEL INJECTOR ASSEMBLY, CYLINDER HEAD SIDE MEMBER, AND FUEL INJECTOR INSTALLATION METHOD - A fuel injector assembly includes a modular fuel injector unit and a cylinder head side member. The modular fuel injector unit includes a first fuel injector with a first seal, a second fuel injector with a second seal and a fuel distribution pipe coupled together as a single installable unit. The cylinder head side member includes a first insertion hole with a first fitting section and a second insertion hole with a second fitting section. The first and second insertion holes and the first and second seals of the first and second fuel injectors are arranged such that as the modular fuel injector unit is being mounted to the cylinder head side member, the first seal undergoes a maximum compressive deformation in the first fitting section at a time that does not coincide with a time that the second seal undergoes a maximum compressive deformation in the second fitting section. | 09-30-2010 |
| 20100186684 | COOLING SYSTEM FOR INTERNAL COMBUSTION ENGINE - A cooling system for cooling an internal combustion engine includes a first portion, a second portion and a bypass valve. The first portion forms a first fluid chamber through which a cooling medium passes as it flows from the engine to a heater that utilizes heat generated by the internal combustion engine. The second portion forms a second fluid chamber through which the cooling medium passes as it flows from the heater to the engine. The second fluid chamber is arranged adjacent to the first fluid chamber. The bypass valve is arranged inside the first fluid chamber and the second fluid chamber to form a bypass flow passage connecting the first fluid chamber and the second fluid chamber. The bypass valve is configured and arranged to automatically close the bypass flow passage when a temperature of the cooling medium is equal to or higher than a first prescribed temperature. | 07-29-2010 |
| 20100095922 | VAPOR-LIQUID SEPARATING STRUCTURE - A vapor-liquid separating structure for an engine includes an inlet section, a discharging section, a collecting section and a vapor-liquid separating section. The inlet section is configured and arranged to take in blow-by gas from inside a valve mechanism chamber. The discharging section is configured and arranged to discharge the blow-by gas taken in through the inlet section. The collecting section is configured and arranged to collect a majority of oil entered into the vapor-liquid separating structure through the inlet section. The vapor-liquid separating section is configured and arranged to execute a vapor-liquid separation treatment with respect to the blow-by gas while guiding the blow-by gas taken in through the inlet section to the discharging section without the blow-by gas passing through the collecting section. | 04-22-2010 |
| 20090301448 | BLOW-BY GAS RECIRCULATION STRUCTURE FOR INTERNAL COMBUSTION ENGINE - A blow-by gas recirculation structure includes a cylinder head including an intake manifold mounting surface and a cylinder block mounting surface with a first intake passage extending between a first intake opening formed in the intake manifold mounting surface and a first intake port formed in the cylinder block mounting surface, and a second intake passage extending between a second intake opening formed in the intake manifold mounting surface and a second intake port formed in the cylinder block mounting surface. The cylinder head further includes at least one blow-by gas passage for recirculating blow-by gas to the first intake passage. The intake manifold mounting surface has at least one enlarged recess fluidly connected between the blow-by gas passage and the first intake passage, the enlarged recess being disposed between the first and second intake openings and at least partially aligned with centers of the first and second intake openings. | 12-10-2009 |
| 20090205619 | BLOW-BY GAS RECIRCULATION STRUCTURE FOR ENGINE - A blow-by gas recirculation structure for an engine includes a gas-liquid separating member, a cylinder head, a support member and a mounting bolt. The gas-liquid separating member includes a gas-liquid separating passage to separate oil from the blow-by gas. The cylinder head includes a communication passage communicating with the air intake system. The support member is configured and arranged to rotatably support a camshaft in the cylinder head. The mounting bolt securely fastens the support member to the cylinder head with the mounting bolt threadedly engaging within the communication passage of the cylinder head. The mounting bolt has an axial through hole axially extending there-through and communicating with the gas-liquid separating passage so that the blow-by gas that has passed through the gas-liquid separating passage is recirculated from the axial through hole of the mounting bolt, through the communication passage, and into the air intake system. | 08-20-2009 |
| 20090178636 | CAMSHAFT AND CAMSHAFT MANUFACTURING METHOD - A cam lobe of a camshaft has a base circle portion and a lifting lobe portion. A camshaft journal of the camshaft has first and second bearing portions that bear reaction forces from the base circle portion and the lifting lobe portion, respectively. The first bearing portion has an axial width smaller than that of the second bearing portion with at least a portion of an axial end surface of the first bearing portion facing the cam lobe being disposed away from the cam lobe relative to an axial end surface of the second bearing portion. The base circle portion has an axial width smaller than that of the lifting lobe portion with at least a portion of an axial end surface of the base circle portion facing the camshaft journal being disposed away from the camshaft journal relative to an axial end surface of the lifting lobe portion. | 07-16-2009 |
