Abstract: An inlet manifold arrangement is disclosed for a four-stroke internal combustion engine having at least one working cylinder with inlet valves and outlet valves and an inlet manifold assembly. The inlet manifold assembly has a flow direction for fluid (such as a fuel-air mixture) in the inlet direction, and an end section near an air filter device. The manifold assembly also has a throttle valve arrangement and a non-return valve which blocks in the direction opposite to the flow direction. The non-return valve is situated, in relation to the flow direction, between the end section of the inlet manifold assembly and the throttle valve arrangement.

Abstract: A marine drive has a propulsion unit, a supporting cradle, a resilient mount that couples the propulsion unit to the supporting cradle, a sound blocking member that extends across an internal gap between the propulsion unit and the supporting cradle, and a cowling system having upper and lower cowlings that cover at least a portion of the propulsion unit and lower cradle covers that cover at least a portion of the supporting cradle. The upper and lower cowlings are separated from the lower cradle covers by an external gap so that the upper and lower cowlings can move along with the propulsion unit and with respect to the supporting cradle and the cradle covers. The sound blocking member blocks the sound which otherwise would emanate from propulsion unit via the internal gap and then from the marine drive via the external gap.

Abstract: A supercharger structure for an all terrain vehicle or a utility vehicle includes an engine body and a supercharging device. The engine body includes a cylinder having an intake passage and an outtake passage. The supercharging device includes a supercharger, a throttle, an intake manifold, and at least one nozzle. The supercharger includes a chamber having an inlet coupled with the throttle and an outlet connected to the intake manifold. The intake manifold and the at least one nozzle intercommunicate with the intake passage. The at least one nozzle is connected to a fuel supply pipe of a vehicle. External air is drawn in by a guiding device in the chamber, flows through the throttle and the inlet into the chamber, and is pressurized. The pressurized air flows through the intake manifold to mix with fuel ejected by the at least one nozzle and then enters the cylinder.

Abstract: In a saddle-ride type vehicle in which a cylinder head of a single-cylinder engine main unit has a front wall and a rear wall, an exhaust system being connected to the front wall and an intake system being connected to the rear wall, a joining surface of the cylinder head to a head cover is formed on a plane crossing a cylinder axis, the plane being inclined downward toward a front. Rotation axes of camshafts are arranged on the plane. An axis of a valve stem of a throttle valve is arranged on the plane. A curve cover curved so as to cover driven sprockets fixed to the camshafts is formed on one side in a vehicle width direction of the head cover. A drum housing box housing a throttle drum fixed to one end of the valve stem is arranged close to the curve cover.
