Definitions

  • the invention relates to a cylinder head of the type according to the preamble of claim 1.
  • the longitudinal channel extends next to the row of combustion chambers just above the parting plane of the cylinder head to the cylinder block.
  • the connecting channels are parallel to this parting plane and at an angle to the row of combustion chambers and the longitudinal channel. All connection channels are drilled from the outside of the cylinder head and sealed there with cover caps. This design is only suitable for parallel hanging valve arrangements because the connecting channels parallel to the parting plane do not allow targeted cooling of the hottest points of the cylinder head in a V-shaped valve arrangement.
  • cylinder head of a similar type according to DE-A 3123538 several longitudinal channels are provided, two of which are open to the parting plane of the cylinder head to the cylinder block.
  • One of these two longitudinal channels has essentially only a longitudinal flow across the entire length of the cylinder head and runs in an arc shape parallel to the combustion chamber contours.
  • the second open longitudinal duct is arranged at a greater distance laterally outside of the combustion chambers and is connected to water spaces in the cylinder block via transverse bores which are closed on the opposite outside of the cylinder head and vertical bores which each open there.
  • Two further longitudinal channels extend over the combustion chambers and one of them in the area of valve guides.
  • the object of the invention is to arrange the longitudinal channel and the connecting channels in such a way that targeted cooling of hot cylinder head areas in all customary cylinder head types and a design of the longitudinal channel and the connecting channels that can be represented directly by drilling or casting molds without additional sealing measures can be achieved.
  • This object is achieved by the features of the characterizing part of claim 1.
  • This design results in a direct cooling effect of the longitudinal channel and the connecting channels on the hottest areas of the cylinder head. Since the straight-line connecting channels start directly from the niche-like water spaces, no plugs or sealing lids are required, so that production is simple and inexpensive.
  • a further development of the invention for a cylinder head with V-shaped hanging and offset in the longitudinal extension of the same valve is characterized in claim 2.
  • This design specifically cools places of the cylinder head that are subject to high thermal loads, in particular the area around the exhaust ports, the area between the exhaust port and spark plug, and the combustion chamber walls by means of targeted longitudinal and transverse flow through the longitudinal port and the connecting ports.
  • the oil temperature in the cylinder head is kept low due to its good cooling.
  • a die-cast cylinder head 1 for water-cooled internal combustion engines has several niche-like water spaces 2 and 3.
  • the water spaces 2 and 3 can be formed towards the parting plane 1 'between the cylinder head 1 and the cylinder block (not shown) and are arranged around combustion chambers 4.
  • the water spaces 2 and 3 are on the outside of the cylinder head 1. They have sections 5 and 6 which extend between two adjacent combustion chambers 4.
  • a longitudinal channel 7 is arranged at a distance from the combustion chambers 4.
  • Connecting channels 8, 9 and 10 extend from the water spaces 2 and 3 and from section 5 of the water space 2 to the longitudinal channel 7.
  • the connecting channels 8, 9 and 10 are arranged obliquely to the parting plane 1 '. They are made by drilling from water spaces 2 and 3 or from section 5 of water space 2.
  • connecting channels 8, 9 and 10 are also possible to form these connecting channels 8, 9 and 10 by means of casting molds.
  • the longitudinal channel 7 can be shaped toward the end faces of the cylinder head 1, not shown. There is no need for plugs and other closures, since the connecting channels are directly from the water spaces 2 and 3 or from section 5 of water chamber 2.
  • the cylinder head 1 has inlet and outlet ducts 11 and 12 that open out laterally.
  • the valves of which only the valve guides 13 and 14 are shown, are suspended, offset and arranged in a V-shape with respect to one another.
  • the inlet valve seat 15 and the outlet valve seat 16 are arranged correspondingly offset from one another.
  • a bore 17 for a spark plug is arranged opposite the inlet valve 15, so that it is on the same side as the outlet channel 12.
  • the connecting channels 8 and 10 are arranged on both sides of the exhaust valve seat 16 and the exhaust channel 12.
  • the connecting channel 8 is thus between the outlet channel 12 and the bore 17 for the spark plug.
  • the connecting duct 9 is arranged essentially opposite the outlet duct 12.
  • the longitudinal channel 7 lies between the valve guides 13 and 14.
  • the angle of inclination of the connecting channels 8, 9 and 10 with respect to the parting plane 1 ' is between 30 and 60 °.
  • the design described results in a cylinder head 1 with a low operating weight, since it has only a small water content. Due to the low water content, a good flow and cooling of the cylinder head can also be ensured with a water pump of relatively low drive power.
  • the longitudinal channel 7 cools the valve guides 13 and 14 and moreover protects the oil located in the valve chamber 18 above them from excessive heating.
  • the area between the exhaust port 12 and the bore 17 for the spark plug and the walls of the combustion chambers 4 are preferably cooled by means of a defined cross flow flowing through the connecting ports 8, 9 and 10 .
