    摘要： A two-stroke engine has a cylinder with a combustion chamber which is bounded by a piston which drives a crankshaft which rotates in a crankcase. The crankcase is connected to the combustion chamber via an overflow passage in the lower dead centre region of the piston. The two stroke engine has an intake passage. A carburetor forms a section of the intake passage. The intake passage is partially divided into an air passage, which supplies combustion air into an overflow passage, and a mixture passage which opens into the crankcase. A throttle valve mounted pivotably in the carburetor controls the combustion air quantity supplied to the air and mixture passages. An air-guiding element arranged on the passage wall of the air passage guides the combustion air passing between the throttle valve and passage wall in the idling position of the throttle valve in the direction of the mixture passage.

    摘要： A two stroke engine comprises a cylinder, in which a combustion chamber bounded by a piston is formed, and an intake passage. A carburetor forms a section of the intake passage, within which a throttle element is mounted pivotably, and at least one main fuel opening and at least one idling fuel opening open into the intake passage, which is divided downstream of the carburetor into an air passage and a mixture passage. The idling fuel opening feeds a secondary passage arranged within the mixture passage. In the idling position, the throttle element may be arranged adjacent to the upstream entry opening in the secondary passage, and the throttle element may have an opening which, in the idling position of the throttle element, is arranged in the region of the entry opening and connects the secondary passage to that region of the intake passage located upstream of the throttle element.
