摘要： A cylinder is produced of die cast metal and is for a two-stroke engine in a portable handheld work apparatus such as a motor chain saw. A combustion chamber (3) is formed in the cylinder (2) and this combustion chamber is delimited by a piston (5). In the cylinder wall (16), there is an outlet (10) for conducting away the combustion gases from the combustion chamber (3). Transfer channels (14a, 14b) are provided which open into the combustion chamber (3) via transfer windows (12, 15) and supply the operating medium from the crankcase (4) needed for operating the two-stroke engine. The transfer channels (14a, 14b) are configured in the cylinder wall (16) as channels opening radially to the outside and are closed by a seated cover (23).

摘要： A two-stroke engine has an intake arrangement including a carburetor. An intake channel divides into a mixture channel and an air channel. An intermediate flange is mounted between the carburetor and the cylinder. This flange has a carburetor connecting surface, which faces toward the carburetor, and a cylinder connecting surface which faces toward the cylinder. Referred to the flow direction in the intake channel, the air channel divides upstream of the cylinder connecting surface into two branches. The first branch has a first longitudinal center axis and the second branch has a second longitudinal center axis. The intersect points of the center axes with the connecting surfaces are mutually connected via an imaginary connecting line in the carburetor connecting surface or the cylinder connecting surface. The two connecting lines conjointly define an angle β in the carburetor connecting surface with this angle being greater than 0°.

摘要： A carburetor including a mixture channel and an air channel that are separated from one another, wherein a fuel opening opens into the mixture channel. A throttle element is rotatable about an axis of rotation that extends transverse of the direction of flow in the mixture channel and in the air channel and extends through both channels. As a function of its position, the throttle element throttles a flow cross-section of the mixture channel and the air channel. The flow cross-section of a portion of the mixture channel and/or of the air channel has a non-circular shape in the vicinity of the throttle element.

摘要： A connector between a carburetor and a cylinder connection of an internal combustion engine of an implement is provided. The flow channel formed in the connector is provided with raised portions over the inner periphery of the channel. To avoid fluctuations in the speed of the engine as a function of changes in position of the implement, the raised portions are embodied as wall portions that are oriented approximately transverse to the center line of the channel. The wall portions provide a flow cross-section for the channel that varies in a step-shape or terrace-shaped manner.

摘要： An internal combustion engine, for example a two-stroke engine having scavenging collection, is provided. The combustion chamber formed in the cylinder is delimited by a reciprocating piston. A fuel/air mixture prepared in the Venturi section of a diaphragm carburetor is supplied to the engine. The air portion of the mixture is conveyed to the Venturi section via an intake channel, and the fuel portion is conveyed to the Venturi section via a main nozzle path that branches off from a fuel-filled control chamber to which fuel is supplied via a fuel line and a feed valve that is controlled by a control diaphragm that delimits the control chamber. A device is provided for varying the air portion and/or the fuel portion at full load. Connected to the device is a control unit that receives, as an input variable, an operating parameter of the engine that varies as a function of engine speed. The device is actuated as a function of the output signal of the control unit.

摘要： The invention relates to a two-stroke engine in a portable handheld work apparatus. A combustion chamber (3) is formed in a cylinder (2) and the chamber is delimited by a piston (5). At least one transfer channel (14) is provided which connects the crankcase (4) to the combustion chamber (3). An air channel (22) opens into the transfer channel (14) and this channel supplies essentially fuel-free gas, preferably air. The intake channel (28) of a carburetor (8) is connected to an intake opening (45) in the housing base (41) of the air filter housing (43) upstream of a carburetor throttle flap. The intake channel (28) connects downstream of the carburetor throttle flap to an intake channel (9) to the crankcase (4). To provide an ignition-ready mixture in order to start and run up the engine, it is provided that the air channel (22) is connected to a bypass opening (25) in the housing base (41) of the air filter (42) and a common pivotable choke element (24) is assigned to the intake opening (45) as well as the bypass opening (25). The choke element (24) clears the openings (25, 45) in the operating position and closes the passthrough cross section of the bypass opening (25) in the start position whereas the passthrough cross section of the intake opening (45) is reduced to a start cross section.
