ARRANGEMENT IN A TWO CYCLE COMBUSTION ENGINE

摘要

Device for a two-stroke combustion engine (10) with internal combustion, comprising a number of engine cylinders (21; 21-1 -21-5), where each cylinder encompasses a pair of pistons (44, 45) which can move to and from each other and for each piston pair a common, intermediate working chamber (K), while each piston (44, 45) is equipped with its own axially moveable piston rod (48, 49), the outer end of which, by way of a support roller, pushes against its respective curve-shaped, i.e. sine curve shaped, cam guide assembly (12a, 12b). A pump system (200), comprising a piston - and a cylinder arrangement is arranged to one or both of the outer ends of the axially moveable piston rods (48, 49).
