Abstract

A two-stroke internal combustion engine, in particular for portable tools such as power saws, bush cutters, etc., comprising a bed (2) in which for the reciprocating piston (8) at least one chamber (44) is provided to which the mixture inlet port (20) and the spent gas outlet port (30) are connected, characterised in that the spent gas outlet port (30) is provided with a valve (32), the opening and closure of which are controlled by the rotation of the piston crankshaft (16).

THE CARTER IS CONSTRUCTED SO THAT THE CARBURETOR CAN BE HORIZONTALLY POSITIONED. THE ROTATION DIRECTION OF THE CRANKSHAFT IS REVERSED T.O.V. AN EXISTING ENGINE BLOCK. THE CRANKSHAFT ROTES THE SAME DIRECTION AS THE FLOW DIRECTION OF THE AIR-FUEL MIXTURE. THE AIR-FUEL MIXTURE FLOWS FROM THE CARBURETOR THROUGH A SEPARATE FLOW CHANNEL IN THE CARTER THROUGH THE CRANKSHAFT. AN INTERMEDIATE WHEEL IS NECESSARY AT THE INNOVATIVE CARTER.
