Abstract

See full text

A power tool has an internal combustion engine with a piston supported in the cylinder and delimiting a combustion chamber. A crankshaft is rotatably supported in the crankcase and driven by the piston. Combustion air is supplied to the combustion chamber via an intake passage that has a piston-controlled inlet opening and an intake section formed within the cylinder. The bottom of the intake section, when the cylinder axis is vertical and the crankcase is beneath the combustion chamber, connects lowermost points of passage cross-sections arranged in the intake section perpendicular to the flow direction. The bottom descends toward the crankcase when the longitudinal cylinder axis is vertical. A ramp arranged in the intake passage next to the inlet opening deflects a portion of flow flowing within the intake passage. The ramp, when the longitudinal cylinder axis is vertical, ascends in flow direction toward the crankcase.
