摘要： An air cleaner for an internal combustion engine facilitates is made compact and maintenance work for cleaning or replacing the cleaner element of the same. An air cleaner case (14) holding a cleaner element (13) is a three-part structure essentially consisting of a body (16) having opposite open ends and provided with an air inlet (40), a bottom wall (15) detachably joined to one of the opposite open ends of the body (16) and connected to the air intake passage of the carburetor (5), and a cover (17) detachably joined to the other open end of the body (16). The bottom wall (15), the body (16) and the cover (17) are fastened together by a stud bolt (25) and a fastening nut (37). The cover (17) has a concave part (44) defining a space for receiving the fastening nut (37) and provided with drain holes (50). When the air cleaner (4) is disposed above the carburetor (5), the drain holes (50) are positioned right above the fuel flow adjusting screws (11) of the carburetor (5). A screw operating tool inserted from above the cover (17) in each of the drain holes is able to reach each of the fuel flow adjusting screw (11).

摘要： A water-cooled V-type engine includes: a crankcase in which a crankshaft is rotatably disposed; two cylinders disposed on the crankcase so as to form V-shape; a starter disposed below one of the two cylinders; and a cooling system for cooling the engine with a cooling water. The cooling system includes: a radiator for cooling the cooling water; water jackets disposed on the two cylinders; and a thermostat disposed in a supply line having one end connected to a water outlet formed in a lower end part of the radiator and the other end connected to inlets of the water jackets. The thermostat is disposed below the other of the two cylinders. The engine can be formed in compact construction and the piping of the cooling system can be simplified since the starter and the thermostat are disposed below the tilted cylinders, respectively.

摘要： This disclosure relates to an air cleaner for use in an air-cooled engine including a cooling fan within a fan housing. The cleaner is connected to draw air from the housing, and includes a casing having a side wall, an air inlet opening in the fan housing, an air passage formed within the casing and extending from the inlet along the wall, the passage including a curved portion, and a narrow opening formed in the wall adjacent the curved portion. The curved passage causes dust particles to move by reason of inertia to the radially outer side of the passage and the particles are removed through the narrow opening.

摘要： A lubricating system for an internal combustion engine is disclosed. This system includes a pair of passages formed between a crank chamber for reserving oil and an air-oil separating chamber accommodating a mechanism for actuating overhead valves. The pair of passages are constituted by a breather passage formed in the upper portion of a cylinder and the oil-returning passage formed in the lower portion of the cylinder. The breather passage has a valve for allowing a fluid to pass solely toward the air-oil separating chamber and a large oil-circulating resistance is imparted to the fluid flowing toward the air-oil separating chamber through the oil-returning passage, thereby circulating an oil mist in one direction only by using the reciprocal motion of each piston. Even when the engine is inclined, oil is prevented from flowing back from the crank chamber to the separating chamber through the oil-returning passage.
