Abstract

The invention relates to a sealing system for sealing a cylinder head (2) against a cylinder sleeve (1) of a single- or multi-cylinder internal combustion engine, notably a four-stroke diesel engine, with a divided cast iron crankcase consisting of two half-shells (3) connected to each other by screws, and wherein the joint plane runs in the direction of the crankshaft and the cylinder axis. The half-shells (3) comprise recesses for housing separate cylinder sleeves (1) and separate cylinder heads (2) are provided for each cylinder. The inventive sealing system comprises an annular sealing element. An annular groove (7), being open towards the combustion chamber, is provided in the cylinder head (2) and arranged in such a way that at least part of the prolongation of the cylinder sleeve (1) configured as sealing unit (5) is housed thereby forming a press fit. The annular sealing element is configured as a separate annular seal (4) which is supported on a sealing surface of the cylinder head (2) and radially supported on a sealing surface of the half-shells (3). Said annular seal thereby seals an annular gap (16) between the radially outer peripheral surface of the cylinder head (2) and the recesses of the half-shells.

Description

technical field

[0001] The invention relates to a sealing system for a single-cylinder or multi-cylinder internal combustion engine, especially a four-stroke diesel engine, which seals the cylinder head relative to the cylinder liner. Faced in the direction of the crankshaft- and cylinder axis, where the housing half-shells have recesses for accommodating specific cylinder liners and each cylinder is provided with a separate cylinder head, the sealing system includes annular sealing elements. Background technique

[0002] An internal combustion engine with a sealing system of this type is described in European patent EP0883740B1, the technical content of which is the background of the present invention. A metal ring seal is used here for water and gas sealing of the combustion chamber (see Figure 5) between the cylinder head and the cylinder liner, which is sandwiched between the sealing surfaces of the cylinder liner and the cylinder head between. An axial force which is ...
