Japanese Patent JP2002535546
Kind Code:
A
Abstract:
Crankcase scavenged two-stroke internal combustion engine (1), in which a piston ported air passage is arranged between an air inlet (2) and the upper part of a number of transfer ducts (3, 3'). The air inlet is equipped with a restriction valve (4), controlled by at least one engine parameter, for instance the carburettor throttle control. The air inlet extends via at least one connecting duct (6, 6') to at least one connecting port (7, 7') in the engine's cylinder wall (12). The connecting port (7, 7') is arranged so that it in connection with piston positions at the top dead centre is connected with flow paths (9, 9') embodied in the piston (13), which extend to the upper part of a number of transfer ducts (3, 3'), and the upper edge of the respective connecting port (7, 7'; 8, 8') is located as high or higher in the cylinder's axial direction than the lower edge of the respective transfer duct's port (31, 31').
