20130115832 | MARINE VESSEL PROPULSION DEVICE - A marine vessel propulsion device includes a propeller rotatable around a propeller axis, a duct that surrounds the propeller around the propeller axis, an internal combustion engine that rotates the propeller relative the duct, and an electric motor that rotates the propeller relative to the duct. The propeller includes a plurality of blades, and a cylindrical rim that surrounds the plurality of blades around the propeller axis. The electric motor rotates the propeller by rotating the rim. | 05-09-2013 |
20130115833 | MARINE VESSEL PROPULSION DEVICE - A marine vessel propulsion device includes a bracket that is attachable to a marine vessel, a duct that is rotatable around a steering axis with respect to the bracket, a propeller that is rotatable with respect to the duct around a propeller axis extending in a direction perpendicular or substantially perpendicular to the steering axis, and an electric motor that rotates the propeller. The propeller includes a plurality of blades and a cylindrical rim that surrounds the plurality of blades, and is surrounded by the duct. The electric motor rotates the rim with respect to the duct. | 05-09-2013 |
20130137317 | MARINE VESSEL AND MARINE VESSEL PROPULSION UNIT - A marine vessel includes a hull, a jet pump disposed outside the hull, and an electric motor arranged to drive the jet pump. The jet pump includes a water inlet, a jet nozzle disposed posterior to the water inlet, and a flow path connecting the water inlet and the jet nozzle, and is arranged to jet water, taken in through the water inlet, through the jet nozzle. The electric motor is disposed between the hull and the jet pump. | 05-30-2013 |
20130139627 | SHIFT MECHANISM, AND VEHICLE EQUIPPED THEREWITH - A shift mechanism that provides a shift mechanism for enabling smooth gear shifting by a transmission, and a vehicle equipped therewith. With this mechanism, a shift drum, to which shift forks are connected via grooves on an outer periphery, is held every predetermined rotation angle. When differences are produced in the degree of rotation between a third rotating member that rotates by motor rotation and a second rotating member that rotates in accordance with the third rotating member, bias is accumulated in a torsion spring. Bias that is accumulated is released when the rotation angle of the third rotating member equals or exceeds a predetermined angle of rotation, rotating a first rotating member via a second rotating member, and rotating the shift drum quickly. | 06-06-2013 |
20130157532 | OUTBOARD MOTOR AND WATERCRAFT INCLUDING THE SAME - An outboard motor includes an engine, a water intake opening arranged to suck in water, and a water supply path arranged to supply the water sucked in through the water intake opening to the engine. The engine includes a water path arranged to cause the water supplied from the water supply path to flow in a water jacket of a cylinder head, a water jacket of an exhaust pipe, and a water jacket of a cylinder block in this order. | 06-20-2013 |
20130157533 | OUTBOARD MOTOR AND WATERCRAFT INCLUDING THE SAME - An outboard motor includes a left bank and a right bank. An exhaust port in each of the left bank and the right bank is arranged outward relative to a cylinder axis line in an outer motor width direction. A left exhaust pipe is arranged outward relative to a crankcase and the left bank in the outer motor width direction. A right exhaust pipe is arranged outward relative to the crankcase and the right bank in the outer motor width direction. A catalyst is located in each of the left and right exhaust pipes. | 06-20-2013 |
20130157534 | OUTBOARD MOTOR AND WATERCRAFT INCLUDING THE SAME - An outboard motor includes a V-shaped 4-cycle engine including fuel injection devices that directly inject fuel into combustion chambers. The engine includes a left intake path including a left path extending from an intake port in a left bank in an obliquely rearward and rightward direction, and a right intake path including a right path extending from an intake port in a right bank in an obliquely rearward and leftward direction. The left fuel injection device is located to the right of a cylinder axis line in the left bank. The right fuel injection device is located to the left of a cylinder axis line in the right bank. | 06-20-2013 |
20130160590 | SPEED CHANGE CONTROLLER FOR SADDLE-RIDE TYPE VEHICLES - A speed change controller is provided on a saddle-ride type vehicle and is suited to manipulation by a foot. The speed change controller for saddle-ride type vehicles comprises a detection mechanism that detects operation by a driver for speed change, and a speed change mechanism that performs speed change on the basis of speed change operation detected by the detection mechanism. The detection mechanism provided by the invention comprises an operation part manipulated by a foot for speed change and including a moving part, which moves relative to the vehicle on the basis of manipulation by a foot, and a detection unit that detects that the moving part moves a predetermined amount or more. | 06-27-2013 |
20130186352 | INTERNAL COMBUSTION ENGINE AND STRADDLE-TYPE VEHICLE INCLUDING THE SAME - A forced air-cooled engine includes a crankcase, a cylinder block, a cylinder head, a cooling fan, and a shroud arranged to cover a portion of the crankcase, the cooling fan, and a portion of the cylinder block and a portion of the cylinder head. Fins are provided at least in a region of the cylinder block covered by the shroud. The shroud includes a facing wall portion that faces the fins . An exhaust opening is provided between the facing wall portion and the cylinder block, and opens away from the cooling fan. | 07-25-2013 |
20130186353 | INTERNAL COMBUSTION ENGINE AND STRADDLE-TYPE VEHICLE INCLUDING THE SAME - An engine includes a crankcase, a cylinder block, a cylinder head, a piston, a cooling fan, and a shroud having an inner wall portion and an outer wall portion. A suction port is provided in a region of the outer wall portion facing the cooling fan. The inner and outer wall portions define a duct extending from the suction port to reach at least a portion of the cylinder block and/or at least a portion of the cylinder head. | 07-25-2013 |
