Definitions
- Cylinder head for water-cooled internal combustion engines that can be manufactured using the die casting process
- 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 from different sides into the cylinder head. Part of the water spaces is closed by a flange of the intake manifold and / or exhaust system, which is also designed as a cover, while another part of the water spaces has to be closed in a complex manner by many individually pressed-in metal covers.
- 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 a cylinder head which can be produced in the die casting process to create the type described, which has a targeted cooling of highly heat-stressed places with low water content and is easy and inexpensive to manufacture.
- the invention solves this problem by the features of the characterizing part of claim 1. Due to the design according to the invention, a large part of the water spaces with a large water content to be closed to the outside is eliminated. In addition, in the case of drilled transverse ducts, only their inlet openings need to be closed by plugs, covers 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 feature of claim 2 results 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 molded cylinder liners. Due to the features of claim 3, the introduction of the transverse channels to holes for cylinder head screws is made possible and an offset valve arrangement with a short favors inlet and outlet channels and a corresponding spark plug arrangement.
- the feature of claim 4 enables the shaping of the longitudinal channel during casting and by the feature of claim 5, 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 claims 6 and 7 support the formation of a defined cross flow through the cylinder head.
- Fig. 1 shows a section along the line I-I of Fig. 2 of a die-cast cylinder head for water-cooled internal combustion engines and
- 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 cylinder liners which may be cast together 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. He is Formable towards its front opening 9, so that only the oblique transverse channels 7 and 7 'have to be drilled.
- Bores 12 for cylinder head screws are arranged perpendicular to the cylinder head-cylinder block parting plane and on a circle around each combustion chamber 6 or the central longitudinal axis of its cylinder.
- Two adjacent wide spaces 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.
- FIG. 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.
- 2 to 5 leading passages 16, 17, 18 and 19 are arranged in the cylinder head gasket 14 from the water jacket 15 of the cylinder block 13 into the niche-like water spaces.
- the most distant passages 16 from the longitudinal channel 8 are the largest and each have at least the same cross section as a transverse channel 7 or 7 '.
- the passages 19 closest to the longitudinal channel 8 are the smallest and their cross section is approximately 1/4 to 1/2 of the cross section of the passages 16.
- 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, and the lubricating oil emerging from the camshaft bearings quickly to drain channels 24. 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). 00In a water-cooled cylinder head (1) of an internal combustion engine, which can be obtained by pressure casting, all the volumes of water (2 to 5) in the form of niches extend to at the cylinder head-cylinder block interface and essentially surround the explosion chambers (6). These water volumes (2 to 5) are connected to the water jacket of the cylinder block (13) by means of passages (16 to 19) convenient in the cylinder head gasket (14) and are interconnected by means of transverse ducts (7, 7 ') and a longitudinal, lateral duct (8). The top of the longitudinal duct (8) constitutes the highest point of the water volumes (2 to 5) and of the ducts (7, 7 'and 8) and the longitudinal duct (8) is provided with an outlet of water (9). The cooling of the cylinder head (1) is effectively controlled thanks to the particular arrangement of the water volumes (2 to 5), of the transverse ducts (7, 7 ') and of the passages (16 to 19) of the cylinder head gasket (14 ) relative to the main components of the cylinder head (1). 00
