Two-stroke engine, especially for landcraft, watercraft, or aircraft models

摘要

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, defines a combination 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. In order to reduce friction of the piston in the bush of such a two-stroke engine, the bottom end of the bush, which adjoins the crank housing is provided with means that increase the temperature-related radial expansion of the bush.
