摘要： An oil pump includes an oil supply pump and an oil recovery pump disposed on an extension line of a crankshaft of an engine. One joint member is provided at an end portion of the crankshaft, and another joint member is provided at an end portion of a pump shaft. The two joint members are coupled to each other on the same axial line within a front cover of an engine. The two joint members have alternating concave portions and convex portions. The convex portions of the two joint members include inclined faces and opposing driving transmission faces. The inclined faces of the convex portions guide the convex portions into the concave portion of the opposing joint member, so that the two joint members are meshed with one another. The crankshaft side joint member is fastened together with an ACG rotor. An oil tank connected to the oil pump is disposed above and very close to the oil pump.

摘要： To provide an inner shim that is unlikely to fall off from a spring retainer even when an anomalous operation of a valve occurs. A spring retainer fixed to the upper end portion of a valve shaft has a shim-attachment hole. An inner shim is fitted into the shim-attachment hole. The bottom face of the inner shim is in contact with the upper end portion of the valve shaft, and the top face of the inner shim is positioned below the upper edge of the shim-attachment hole. A tappet is disposed above the spring retainer, and is allowed to move freely in the axial direction of the valve shaft. A shim-holding projection sticks out from the under face of the tappet, and extends downward. The projection enters, from above, the inside of the shim-attachment hole, and is in contact with the top face of the inner shim.

摘要： An internal combustion engine for a small planing boat for reducing the lateral width of an oil pan in conformity to the configuration of the bottom while securing the filtering surface area of an oil strainer. In addition, a vertical width of the oil pan is maintained to be small to thereby lower the total height of the internal combustion engine. In an internal combustion engine for a small planing boat, an oil pan is provided at the bottom portion of the internal combustion engine with an oil passage for communicating with an oil pump being formed inside the oil pan. A vertical wall of the oil passage is partially cut away to form communication openings each communicating between the inside and outside of the oil passage with the oil strainers being interposed in the communication openings substantially vertically to divide the oil passage into inside and outside.

摘要： A snowmobile, having an arrangement of components in which the layout of various accessory devices is improved for an internal combustion engine mounted thereon. A dry sump oil tank, a water pump and a starter motor are disposed in a concentrated space at a forward-facing portion of an internal combustion engine, which is mounted on a snowmobile at a position close to the front side of a body of the snowmobile. A steering shaft is arranged close to the front portion of the internal combustion engine, and is accommodated by modifying the shape of closely adjacent parts. Accordingly, the limited available space in a snowmobile is effectively used, and a rider riding in back of the engine can easily and closely approach the engine. The limited space inside the snowmobile cover is used effectively, by efficiently arranging selected accessory devices for an internal combustion engine mounted on the snowmobile.

摘要： An internal combustion engine for a small planing boat for preventing supercooling of the internal combustion engine before warm-up while enabling efficient cooling of the internal combustion engine after warm-up. An internal combustion engine for a small planing boat includes a first cooling water path B through which cooling water introduced from a jet propulsion pump flows toward an internal combustion engine main body via an exhaust manifold. A second cooling water path C is provided through which cooling water introduced from the jet propulsion pump flows toward an exhaust pipe via an oil cooler. A bypass cooling water path D is provided for branching a part of cooling water in the second cooling water path C which flows out from the oil cooler, so as to merge into cooling water in the first cooling water path B which flows into the internal combustion engine main body.
