20090071113 | FILTER ELEMENT - A filter element includes an upstream side layer structure disposed on an upstream side in a flow direction of air to be filtrated and formed of a non woven fabric formed by laminating chemical fibers, and a downstream side layer structure disposed on a downstream side in the flow direction of the air and including a plurality of layers including chemical fiber non woven fabric layers formed by laminating chemical fibers. The upstream side layer structure has a fiber density relatively smaller than that of the downstream side layer structure. The downstream side layer structure includes a natural fiber layer such as cotton layer disposed between the chemical fiber non fabric layers, and an oil is impregnated from the upstream side layer structure to the natural fiber layer in the downstream side layer structure. | 03-19-2009 |
20120289104 | OUTBOARD MOTOR - An outboard motor includes an engine, a flywheel, a twisting member, and a damper. The engine includes a crankshaft that is rotatable around a crank axis extending in the up-down direction and includes an upper end portion disposed along the crank axis. The flywheel includes a joint portion that is disposed above the upper end portion of the crankshaft and joined to the upper end portion. The twisting member is disposed along the crank axis above the upper end portion of the crankshaft, and is arranged to rotate around the crank axis together with the crankshaft. The damper is disposed above the flywheel at a distance from the flywheel, and joined to the twisting member. | 11-15-2012 |
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 |
20130203309 | VESSEL PROPULSION APPARATUS - A vessel propulsion apparatus includes an exhaust passage guiding exhaust generated at an engine, a water jacket cooling at least a portion of the exhaust passage, a cooling device supplying water outside the vessel propulsion apparatus to the water jacket, an exhaust sensor detecting a concentration of a component in the exhaust in the exhaust passage, and a non-catalytic porous member disposed in the exhaust passage at an upstream side relative to the exhaust sensor. The non-catalytic porous member is a porous member that does not hold a catalyst. | 08-08-2013 |
20150075469 | OHV ENGINE - An OHV engine with a reduced height includes a cylinder, a piston inside the cylinder, a crank shaft that converts reciprocating movement of the piston into rotating movement, a connecting rod that connects the piston and the crank shaft to each other, and a cam shaft that moves in association with the crank shaft. When the cylinder is viewed from the crank shaft, the cylinder is inclined in an obliquely upward direction so that an angle defined by the cylinder center axis and a horizontal plane is greater than 0 degree and smaller than about 45 degrees. The cam shaft is at a lower position than the cylinder center axis. The cylinder center axis is offset with respect to a line which passes through a rotation axis of the crank shaft and is parallel or substantially parallel to the cylinder center axis, to a side spaced away from the cam shaft. | 03-19-2015 |
20150075476 | FOUR-CYCLE ENGINE AND ENGINE GENERATOR - An engine generator includes a four-cycle engine including a cylinder, one inlet port that supplies air-fuel mixture into the cylinder, one inlet valve that opens/closes the inlet port, a piston reciprocable inside the cylinder, a crank shaft that converts reciprocating movement of the piston into rotating movement, a connecting rod that connects the piston and the crank shaft to each other, and a recoil starter that rotates the crank shaft. The engine has a geometric compression ratio not smaller than about 8.5. The valve closure timing of the inlet valve is defined as a timing when the closing inlet valve has a valve lift of about 1 mm, and is within a range from after the bottom dead center to the top dead center. | 03-19-2015 |
20150075480 | ENGINE - An engine includes a piston inside a cylinder, a crank shaft, a connecting rod, an oil dipper provided in a big end portion of the connecting rod, and a piston pin which connects pin boss regions of the piston to a small end portion of the connecting rod, and a crank case. The piston pin is rotatably movable with respect to the pin boss regions and the connecting rod. There are counter regions between the small end portion and the piston pin, a first counter region on a side closer to a tip portion of the connecting rod and a second counter region on a side closer to the big end portion of the connecting rod. The first counter region includes two ends located farther inward than two ends of the second counter region in an axial direction of the piston pin. | 03-19-2015 |
