Abstract: A piston engine (1) that can be driven using a steam power process and is used in particular for utilizing the waste heat from an internal combustion engine comprises a cylinder bore (5), a cylinder piston (6) which is arranged in the cylinder bore (5) and delimits an operating space (8) in the cylinder bore (5), a rod (21) which is connected to the cylinder piston (6), and a bearing point (37) on which the rod (21) and the cylinder piston (6) connected to the rod (21) are mounted. A peripheral gap (28) is predefined between the cylinder piston (6) and the cylinder bore (5), thus preventing frictional wear between the cylinder piston (6) and the cylinder bore (5), which is particularly advantageous when a water-based working fluid is conducted through the operating space (8) since steam has no lubricity.
