Abstract

In a two-stroke internal combustion engine with facing cylinders, piston rods extend from the cylinders into a central crank guide located within a crankcase. A crankpin is located within the crankcase and a sliding piece forms the bearing points between the crankpin and the crank guide. The sliding piece is made up of solid or laminated ceramic components so that the friction heat can be removed using the water from the engine cooling circuit.
