摘要： To miniaturize an exhaust manifold to facilitate disposition of an engine in a boat body. A multiple cylinder engine having an exhaust manifold on a side portion thereof is disposed such that a crankshaft thereof extends along forward and rearward directions of a boat body. The exhaust manifold has a structure wherein exhaust pipes connected to exhaust ports of the engine are distributed upwardly and downwardly in such a manner as to form confluence pipes above and below the exhaust ports and the confluence pipes are further joined to each other to form an exhaust gas exit from the exhaust manifold. The exhaust gas exit is disposed at a substantially central portion of an internal space of the boat body in the vertical direction and an exhaust gas turbo charger is connected to the exhaust gas exit.

摘要： In a transmission for a saddle type vehicle wherein a shift position sensor for detecting the angular position of a shift drum has a sensor shaft disposed coaxially with the shift drum and wherein an engaging pin disposed along a plane orthogonal to the center axis of the sensor shaft and inserted and passed through and fixed to the sensor shaft is engaged with an engagement groove provided at one axial end of the shift drum, to restrain abrasion or torsion from occurring between the engagement groove and the engaging pin even if a radial load is exerted on the shift drum at the time of a shift change and thereby to promise enhanced durability. The longitudinal direction of the engagement groove is set in a direction orthogonal to the direction in which the greatest one of radial loads on the shift drum is exerted.

摘要： In a decompression unit including a decompression arm, a decompression unit for internal combustion engine is provided in which the followability in the opening-and-closing operation of the air intake valve or the exhaust valve with respect to the cam at high-revolution speeds is satisfactory without increasing the equivalent inertia weight of the valve driving system, and for lowering the cost. A decompression unit includes a first decompression cam that takes the operating position when the number of revolutions of the engine is not more than the predetermined number of revolution during startup. A second decompression cam is provided that takes the operating position by manual operation. A decompression arm includes first and second abutting portions that abut against first and second decompression cams, respectively. An adjusting screw is provided for pressing the rocker arm and a resilient member for bringing the first abutting portion of the decompression arm into abutment against the first decompression cam. The decompression arm pivoted by the first and the second decompression cams pivots the rocker arm via the adjusting screw to open the exhaust valve.

摘要： In an internal combustion engine, a pair of suction ports are formed on left and right sides of the rear of the cylinder head with respect to the vehicle body. A pair of exhaust ports is formed on left and right sides on the front side of the cylinder head. Suction poppet valves and exhaust poppet valves for opening and closing the suction ports and the exhaust ports are slidably fitted in guide tubes, respectively. In addition, a valve gear includes a camshaft and a rocker arm pivotally supported on a rocker arm shaft. The rocker arm is formed with a bifurcated end, which crosses an ignition plug on the exhaust poppet valve side. The suction poppet valves are directly driven to open and close by the camshaft.
