ABSTRACT:
A reciprocating piston engine having a sealing system between the cylinder head and the cylinder liner, or the cylinder block, using a metal gasket. It is proposed to improve such a system in a manner that, while large manufacturing tolerances are permitted, i.e. tolerances on the dimensional design of the cooperating parts as well as on the cylinder head bolt torque, reliable gastight sealing of the combustion chamber is ensured at all times. This is essentially achieved in that a circumferential raised portion on the liner flange is the only part that projects beyond the top end (sealing face) of the cylinder block and is matched to the metal gasket in a manner that when the cylinder head is tightened down on the cylinder block, the cylinder head gasket is always stressed above the yield point, with the metal gasket having such a stress/strain characteristic that once the yield point is exceeded, the horizontal deformation range (i.e. where the compressive stress is constant) is as great as possible.
