摘要： A chain-tensioning rod, for an internal combustion engine with an overhead camshaft valvetrain to keep in tension a timing chain, includes a shoe, which is pressed against the timing chain, and a supporting arm of the shoe, allows a simple assembly of the arm and of the relative shoe because the shoe is formed by a monolithic piece having, on one side thereof, a sliding surface and on, the opposite side, a supporting surface and a contact element connected to the supporting surface by a longitudinal central rib; and the supporting arm is formed by an elongated sheet having a longitudinal pass-through slit extending from a distal end thereof, wherein it is open, so that insertion of the supporting arm on the supporting surface takes place by making said rib to slide in the slit, the rib operating as transversal locking device of the supporting arm on the supporting surface.

摘要： An motorcycle air intake structure includes: a container divided by a main baffle into two distinct chambers: a first chamber communicating externally and a second chamber communicating with a throttled body via a feeding duct; the two chambers separated by an air filter, positioned at the main baffle, the first and second chambers extending longitudinally side-by-side defining opposite sides of the air intake structure. The air intake further includes a pre-chamber accessing the first chamber, separated therefrom by a cross wall and communicating therewith via an access duct crossing said wall, with an inlet end thereof arranged in the pre-chamber and an outlet end thereof arranged in the first chamber, the pre-chamber arranged on the front side with respect to a forward vehicle direction. The pre-chamber includes a front access mouth; and a diverting baffle interposed between the access mouth and the inlet end of the access duct.

摘要： A protective cover structure for a motorcycle transmission allows the entrance of clean air. The cover includes: a first cover member to protect the transmission members, longitudinally extending along a direction which coincides with the travel direction, from a receding front area, corresponding to the engine axis, to a rear area corresponding to the rear wheel drive axis, and an inlet hole positioned at an inlet port of the transmission at the receding front area; a second cover member overlapping the receding front area to protect the inlet hole, forming, with the first cover member, an air intake extending from an upper to a lower edge of the first cover member, defining an inlet section, oriented opposite to the motorcycle travel direction; and a baffle, disposed between the first and the second cover members at said air intake, forming a channel driving the air upwardly to the inlet hole.

摘要： In a water-cooled inner combustion engine (1), in particular for equipping scooters and motorcycles, the arrangement of the outer cooling tubes connected to a radiator is simplified by arranging a by-pass valve (27), arranged directly on the engine block (2) at a discharge opening (18) obtained therein, which, when the cooling water is lower than a reference temperature, prevents the water circulation in the radiator (18) and it addresses it through a by-pass line (26) by implementing a cooling circuit wholly included in the engine block (2).
