At least one valve controls the quantity of fuel to be supplied to the engine via the auxiliary channel. Largely fuel-free air is supplied to the engine via the intake channel during idling. During a first revolution of the crankshaft, fuel is supplied via the auxiliary channel, so that a combustible mixture can form in the combustion chamber. During a second revolution, largely fuel-free air is supplied via the auxiliary channel and the combustion chamber is scavenged with largely fuel-free air.

Abstract: A manually guided implement having a housing that accommodates an internal combustion engine for driving a tool. At least an upper handle extends in a longitudinal direction of the implement on an upper side thereof. A first antivibration element connects the handle to the housing, wherein a longitudinal central axis of the antivibration element is inclined relative to a longitudinal central plane of the implement.
Abstract: An apparatus comprising a blower fan, a motor for driving the blower fan, a blower tube for conveying an air stream from the blower fan, and a potential compensation device that is electrically connected with the motor. The potential compensation device includes a charge compensation element having a free end that projects in an exposed manner into the air stream.
Abstract: A carburetor arrangement for a manually-guided implement operated by an internal combustion engine. A carburetor supplies a fuel/air mixture to the engine, with a butterfly valve being disposed in the intake duct of the carburetor and with a choke valve being disposed upstream of the butterfly valve. A start lever is provided for actuating the carburetor in a start phase, and acts upon the choke valve. The start lever can be shifted in a direction of actuation and in an unlocking direction that is independent of the direction of actuation. The start lever can be locked in a rest position relative to the direction of actuation, and after being shifted out of the rest position in the unlocking direction is shiftable in the direction of actuation.
Abstract: An energy attenuation apparatus in fluid communication with tubing adapted to convey a liquid under pressure, and including a liquid-conveying unit in fluid communication with the tubing and having a diameter greater than the tubing diameter.
