The engine consists of a cylinder block with at least one cylinder, in which the piston, which is connected to a crankshaft via a connecting rod, is accommodated to move and on which a cylinder head is mounted that bounds a combustion chamber into which controlled gas exchange openings lead. The piston consists of first and second piston parts (9.1,10.1) that can be displaced relative to each other to a limited extent against a spring force.
