Abstract (en)
[origin: WO2007003064A1] Disclosed is a two-stroke engine, especially for landcraft, watercraft, or aircraft models, comprising a piston which can be moved up and down within a bush (10), defines a combustion chamber at the top, and is connected to a crankshaft via a con-rod at the bottom, said crankshaft being rotatably mounted in a crank housing located below the bush (10). In order to reduce friction of the piston in the bush of such a two-stroke engine, the bottom end of the bush (10), which adjoins the crank housing is provided with means (15, 16) that increase the temperature-related radial expansion of the bush (10).
