Patent attributes
A power tool has a working tool that is driven by a two-stroke engine that has a cylinder and a piston reciprocating within the cylinder and delimiting a combustion chamber in the cylinder. The two-stroke engine has a crankcase with a rotatably supported crankshaft that is driven by the piston with a connecting rod. Transfer passages connect the crankcase to the combustion chamber in at least one position of the piston. A mixture passage intake supplies a fuel/air mixture, and an air passage supplies combustion air. The combustion chamber has an exhaust port. The two-stroke engine has a transverse plane dividing the cylinder in a direction of the longitudinal cylinder axis. The exhaust port is arranged on one side of the transverse plane, and air passage and mixture passage are arranged on opposite sides of the transverse plane.
