Definitions
- the invention relates to an internal combustion engine according to the preamble of the main claim.
- An internal combustion engine is known from DE-PS 348632, the cylinder head of which is of lightweight construction. However, this does not support the cylinder head plate in the middle in any way.
- the task is solved by the characteristic features of the main claim.
- the compressive forces which act on the center of the cylinder head plate can be transmitted into the screws with the least possible amount of material. Due to the massive configuration of the annular bead on the side of the cylinder head facing away from the cylinder, the fastening points are prevented from spreading apart even under strong pressures. This occurs even if only four screws are used per cylinder.
- the contact zone is evenly loaded by a frustoconical ring support, so that there is no static see faults and therefore no leaks can occur.
- the screw supports are connected only to the half of the cylinder head facing away from the cylinder.
- the inlet and outlet channels can be designed in such a way that they are arranged only on the side of the cone-shaped support part facing the cylinder. As a result, its static stability is only broken through by the recesses for the valve stems.
- a support ring is provided which avoids contact between the two parts.
- This support ring is advantageously made of a deformable material, such as steel, in order to be able to adapt accordingly.
- This dimensionally stable sealing ring is inserted with approximately the same wall thickness as the upper cylinder part between the upper cylinder part and the cylinder head.
- the shape of the upper part of the cylinder prevents the expansion of the upper end of the cylinder by the gas pressure. The result is an improved tightness of the piston above the uppermost piston ring.
- the cooling (oil cooling) of the support ring prevents the static and thermal expansion of the upper cylinder end, so that the forces from the cylinder head are introduced into the cylinder under constant conditions.
- FIG. 1 shows a longitudinal section through an inventive
- FIG. 2 shows a top view of the cylinder head according to FIG. 1
- FIG. 3 shows a longitudinal section as in FIG. 1 in the region of the support ring.
- the force transmission 1 by a cylinder head fastening screw in screw opening 15 denotes the following force distribution 2 to the center of the cylinder head plate and via the ring support 3 to the edge and to the support ring 4.
- the mixing and firing process is also adversely affected by such bending vibrations.
- the shape of the inlet and outlet channels 6 and 7 is subordinate to the shape of the support cone 11 of the cylinder head 14.
- the length of the screw supports 1 _? in the annular bead 13 is so limited that the effect of the ring support 3 on the uniform force distribution over the entire circumference is not influenced.
- the support ring 4 has the task of ensuring gas tightness with the uniform circumferential force of the screw pressure.
- the bore slugs 17 for valve guidance protrude beyond the conical jacket-shaped support part 11.
- FIG. 3 shows a longitudinal section like FIG. 1 in the region of the support ring 4 through the cylinder 8 and the cylinder head 14 of a piston internal combustion engine, the piston 18 being in the uppermost piston position.
- a dimensionally stable metal sealing and support ring 4 projects over the cylinder 8 and encloses it and projects into the cylinder head 14.
