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 to the longitudinal channel. All connection channels are drilled from an outside of the cylinder head and closed there with sealing caps. This training is only suitable for parallel hanging Ventilan orders, because the parallel to the parting connection channels in a V-shaped valve arrangement do not allow targeted cooling of the hottest points of the cylinder head.
  • the object of the invention is to arrange the longitudinal channel and the connecting channels so that a targeted cooling of hot cylinder head areas in all conventional cylinder head types and a design of the longitudinal channel and the connecting channels can be achieved directly by drilling or casting molds without additional sealing measures.
  • 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 at 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 simple and inexpensive production is possible.
  • a further development of the invention for a cylinder head with V-shaped hanging and offset in the longitudinal extent of the same valve is characterized in claim 2.
  • This design specifically cools places of the cylinder head which 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 a 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 lie 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 by casting mold trains.
  • 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 start directly from the water spaces 2 and 3 or from section 5 of the water space 2.
  • the cylinder head 1 has laterally opening inlet and outlet channels 11 and 12, respectively.
  • 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 seat 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 channel 9 is arranged essentially opposite the outlet channel 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 will.
  • the longitudinal channel 7 cools the valve guides 13 and 14 and, moreover, protects the oil located in the valve chamber 18 lying above from excessive heating.
  • thermally highly stressed points, in particular the vicinity of the exhaust ducts 12, the area between the exhaust duct 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 ducts 8, 9 and 10 .
