Claim Text:
1. A two-stroke engine, comprising: a cylinder, in which a combustion chamber is formed, wherein the combustion chamber is bounded by a piston which drives a crankshaft mounted rotatably in a crankcase, wherein the crankcase is connected in the region of the lower dead center of the piston via at least one overflow passage to the combustion chamber, with an intake passage, wherein a section of the intake passage is formed in a carburetor, wherein the intake passage is at least partially divided into an air passage and a mixture passage, wherein the mixture passage opens into the crankcase and the air passage supplies combustion air to an overflow passage, wherein air passage and mixture passage are at least partially separated from each other by a separating wall, wherein a throttle valve is mounted pivotably in the carburetor and controls the combustion air quantity supplied to the air passage and the mixture passage, wherein an air-guiding element is arranged on the passage wall of the air passage, wherein the throttle valve is mounted pivotably by using a throttle shaft, and wherein, in an idling position of the throttle valve, the air passage and the mixture passage are connected via an opening, which is arranged downstream of the throttle shaft, in the separating wall, through which opening air deflected by the air-guiding element flows, wherein the air-guiding element extends from the passage wall into the air passage, and wherein the air-guiding element is designed such that in the idling position of the throttle valve the air-guiding element directs guiding the combustion air passing through the air-guiding element further through the opening in the separating wall and into the mixture passage.
