摘要： A crankcase scavenged two-stroke engine (1) comprises a cylinder (15) including scavenging ports (31, 31') and at least one exhaust port, a piston (13), a connecting rod (17), a crankshaft (18) and a generally sealed crankcase (16). The crankcase inducts a fuel/air mixture and is connected to the scavenging ports (31, 31') by means of transfer ducts (3, 3') which, as the piston (13) is travelling from a lower position towards a higher position, are inducting pure air let in from connecting ports (8, 8') near the scavenging ports (31, 31') in the cylinder (15). The transfer duct (3, 3') volume is less than 20 % of a volume swept by the piston (13) during an entire revolution of the crankshaft (18). Recesses (10, 10') are formed in an outer periphery of the piston (13), said recesses (10, 10') co-operating with the connecting ports (8, 8') in the cylinder wall for controlling the filling of the transfer ducts (3, 3') with air. An inlet tube (22) in the cylinder wall supplies the air/fuel mixture, said inlet tube (22) being connected to the crankcase (16) and covered by the piston (13) as the piston (13) is in the lower position, and open to the crankcase (16) as the piston (13) is in the higher position.

摘要： Flange assembly (56) for supporting a structure that provides scavenging air supply to an internal combustion engine (40) at the carburetor (42) to the engine. The assembly includes a thin-body flange (58) that is configured to be abuttingly installed upon an end surface (48) of the carburetor. The carburetor has its combustion air intake (50) or port exposed at an outer surface for intaking air for the combustion process. The thin construction of the flange enables advantageous positioning of the adaptive flange. The relative dimensioning of the thin-body flange (58) also contributes to its low-impact as a modification to air inlet arrangement. A combustion air aperture (60) is provided that extends through the thin-body flange. The combustion air aperture (60) is located in the flange for alignment with the combustion air intake. By this alignment, fluid communication is established across the flange and into the carburetor when the flange is abuttingly installed upon the carburetor. A scavenging air aperture (64) also extends through the thin-body flange and is spaced apart from the combustion air aperture. A valve assembly (76) is operatively coupled to the thin-body flange and has a valve element (78) positioned at the scavenging air aperture (64) for opening and closing the scavenging air aperture.
