Definitions

  • the invention relates to a cylinder head which can be produced in the die casting process and which is of the type described in the preamble of claim 1.
  • the niche-like water spaces extend into the cylinder head from different sides. Some of the water spaces are closed by a flange of the intake manifold and / or exhaust system, which is also designed as a lid, while another part of the water spaces has to be closed in a complex manner by many individually fitted sheet metal lids.
  • the cylinder head also has a large water content, which results in a high operating weight, a long warm-up period and locally low water speeds.
  • the holes for the cylinder head screws are arranged irregularly around the combustion chambers and additional pressed-in sheet metal covers or plugs are required to close transverse channels which run through some of these holes.
  • the invention has for its object to provide a cylinder head which can be produced in the die casting process and which has a targeted cooling of highly heat-stressed points with low water content and is simple and inexpensive to produce.
  • the invention solves this problem by the features of the characterizing part of claim 1.
  • the design according to the invention eliminates a large part of the water spaces to be closed to the outside with a large water content.
  • only their inlet openings need to be closed by plugs, lids or flange attachments of the intake or exhaust manifold, which do not require much effort.
  • a defined cross flow of the cooling water through the cylinder head is achieved through the transverse channels and the longitudinal channel serving to discharge the cooling water.
  • Embodiments and refinements of the invention result from the subclaims.
  • the features of claim 2 result in good cooling of adjacent or adjacent parts of the combustion chambers and cylinders, especially in internal combustion engines with extremely small cylinder spacings or with cast cylinder liners.
  • the feature of claim 3 enables the shaping of the longitudinal channel during casting and by the features of claim 4, the cooling of the combustion chamber zone located far from the spark plug is favored and the knock resistance of the combustion chamber is positively influenced.
  • the features of claim 5 support the formation of a defined cross flow through the cylinder head.
  • a die-cast cylinder head 1 for water-cooled internal combustion engines has several niche-like water spaces 2, 3, 4 and 5.
  • the niche-like water spaces 2 to 5 can be formed towards the parting plane cylinder head-cylinder block and are arranged around combustion chambers 6.
  • the water spaces 2 and 3 are located on the outside of the cylinder head 1 and the water spaces 4 and 5 are arranged above passages from water space corners, which are determined by possibly molded cylinder liners in the cylinder block.
  • the water spaces 2 to 5 are connected to one another by transverse channels 7 and 7 ′ arranged obliquely to the row of combustion chambers 6, the water spaces 4 being cut essentially on the rear side and the water spaces 5 essentially on the front side.
  • a high longitudinal channel 8 is arranged on one side of the cylinder head 1.
  • transverse channels 7 and 7 'or the water spaces 3 on this side connects the transverse channels 7 and 7 'or the water spaces 3 on this side to one another and serves to discharge the cooling water. It can be shaped towards its front opening 9 so that only the oblique transverse channels 7 and 7 'have to be drilled. The entrance Openings 10 of the transverse channels 7 and 7 'are closed by plugs 11.
  • Bores 12 for cylinder head screws are arranged perpendicular to the plane of the cylinder head-cylinder block and on a circle around each combustion chamber 6 or the central longitudinal axis of its cylinder.
  • Two adjacent combustion chambers 6 each have two of the bores 12 in common.
  • two niche-like water spaces 4 and 5 lie on a connecting line of two bores 12, which is intended to run perpendicular to the row of combustion chambers 6. Due to their oblique arrangement, the transverse channels 7 and 7 'pass the bores 12. 1 shows the cylinder head 1 together with the upper section of a cylinder block 13 and a cylinder head gasket 14 arranged between them.
  • Bores 20 for receiving spark plugs, not shown, are arranged on the side of the cylinder head 1 opposite the longitudinal channel 8.
  • the valve chamber 21, collecting and guide channels 23 are arranged below the camshaft bearings 22, which guide lubricating oil escaping from the camshaft bearings to drain channels 24 quickly. As a result, the lubricating oil gets back into the cylinder block 13 without excessive heating.
  • the arrangement of the niche-like water spaces 2 to 5 towards the cylinder head gasket side results in a good formability of the cylinder head 1.
  • the transverse channels 7 and 7 ' lead particularly close to hot cylinder head locations, such as outlet channels 25, valve seats 26 and 27 and the holes 20 for the spark plugs , so that a good cooling effect is achieved especially at these highly heat-stressed places.
  • This is favored by the cross-sectional selection of the passages 16 to 19 arranged in the cylinder head gasket 14 to the niche-like water spaces, which are severely throttled on the side of the longitudinal channel 8, so that there is a defined flow through the transverse channels 7 and 7 '. Due to their parallel arrangement, all transverse channels 7 and 7 'can be drilled together.

Abstract

Dans une culasse de cylindre (1) refroidi a l'eau d'un moteur a combustion interne, qui peut etre obtenu par coulee sous pression, tous les volumes d'eau (2 a 5) en forme de niches s'etendent jusqu'a l'interface culasse-bloc de cylindre et entourent essentiellement les chambres d'explosion (6). Ces volumes d'eau (2 a 5) sont relies a la chemise d'eau du bloc de cylindre (13) a l'aide de passages (16 a 19) pratiques dans le joint de culasse (14) et sont interconnectes au moyen de conduits transversaux (7, 7') et d'un conduit longitudinal, lateral (8). Le sommet du conduit longitudinal (8) constitue le point le plus haut des volumes d'eau (2 a 5) et des conduits (7, 7' et 8) et le conduit longitudinal (8) est muni d'une sortie d'eau (9). Le refroidissement de la culasse (1) est controle efficacement grace a la disposition particuliere des volumes d'eau (2 a 5), des conduits transversaux (7, 7') et des passages (16 a 19) du joint de culasse (14) par rapport aux organes principaux de la culasse (1). 00
