Definitions

  • the invention relates to a water-cooled cylinder head for a multi-cylinder internal combustion engine according to the features of the preamble of claim 1.
  • a generic water-cooled cylinder head is known for example from DE 199 55 431 AI.
  • the object of the invention is therefore to overcome the disadvantages mentioned above.
  • the cylinder head housing which is made of a light metal construction, can be stiffened and the highly temperature-stressed combustion chamber calottes can be effectively anchored in the cylinder head housing.
  • the rib structure has a longitudinal rib that penetrates the water jacket.
  • Corresponding passage openings are formed in the longitudinal rib so that an unimpeded flow of coolant from the valve outlet to the valve inlet side can take place despite the longitudinal rib penetrating the water jacket.
  • a particularly effective support or suspension of the combustion chamber calottes is ensured if the longitudinal rib is provided centrally between the valve inlet and outlet side and is connected to the individual spark plug domes.
  • the rib structure has diagonal ribs that are connected to the domes for the cylinder head bolts, the spark plug domes and the valve stem guides.
  • a particularly effective rib structure is obtained if, in addition to the longitudinal and diagonal ribs, transverse ribs are provided which connect the domes for the cylinder head screws, which are introduced on the inlet and outlet sides in the cylinder head housing.
  • FIG. 1 is a plan view of a cylinder head housing
  • FIG. 2 shows a longitudinal section through the cylinder head housing according to the line II-II in FIG. 1 and FIG. 3 shows a perspective view of the cylinder head cut along the line 11-11.
  • the cylinder head housing 10 shown in FIG. 1 has three cylinder head sections 12, 14, 16 which have screw-in openings 18, 20, 22 in their central region for spark plugs. Above the screw-in openings 18, 20, 22, two valve stem guides 24, 26 and 28, 30 and 32, 34 for the intake valves are shown for each cylinder. Corresponding valve stem guides 36, 38 or 40, 42 or 44, 46 for the outlet valves are provided below the screw-in openings 18, 20, 22.
  • the cylinder head housing 10 is screwed to the crankcase with the aid of four cylinder head bolts per cylinder.
  • four through bores 48a to 48d or 49a to 49d or 50a to 50d are provided in the cylinder head housing 10 for each cylinder head section 12, 14, 16.
  • a chain case 52 is formed on the end face on the cylinder head housing 10 and accommodates a chain sprocket (not shown) for driving the intake camshaft in an upper section 54.
  • the drive pinion for the exhaust camshaft is arranged in a lower section 56 of the chain case 52.
  • combustion chamber troughs 58, 60, 62 are formed in the cylinder head housing 10, which are delimited by the so-called combustion chamber calottes 64, 66, 68.
  • combustion chamber calottes 64, 66, 68 Above the combustion chamber calottes 64, 66, 68, water jackets 70, 72, 74 are formed which, during operation of the internal combustion engine, the cooling water flows through transversely - from the valve outlet side to the valve inlet side.
  • a rib structure for stiffening the cylinder head housing 10 and for supporting the combustion chamber domes 64, 66, 68, which is described in more detail below.
  • a longitudinal rib 76 is provided which extends over the three cylinder head sections 12, 14, 16 and, as can be seen from FIGS. 2 and 3, connects to the domes 77 of the screw-in openings 18, 20, 22 is connected for the spark plugs.
  • the longitudinal rib extends in the direction of the water jacket 70, 72, 74 and is over - ribs penetrating the water jacket or Bars 78 - cast onto the combustion chamber calottes 64, 66, 68. On the one hand, this stiffens the cylinder head housing 10 and, on the other hand, supports or securely suspends the combustion chamber calottes 64, 66, 68.
  • the rib structure furthermore has two transverse ribs 82, based on the longitudinal axis of the cylinder head (see line II-II), which are each cast onto the domes 81 for the cylinder head screw connections.
  • the webs 78 penetrating the water jacket 70, 72, 74 are oriented in such a way that they, as guide ribs, lead part of the cooling water specifically into the area of the spark plug dome 77.

Abstract

L'invention concerne une culasse refroidie par eau, destinée à un moteur à combustion interne multicylindre et comprenant un carter de culasse (10) muni de conduits d'échange de gaz, des alésages traversants (48, 49, 50) pour le logement de vis de culasse, ainsi que des guides de tige de soupape (24 à 46) pour les soupapes d'admission et d'échappement contrôlant les conduits d'échange de gaz. La culasse selon l'invention comprend également des calottes de chambre de combustion (64, 66, 68) délimitées par une chemise d'eau (70, 72, 74) du côté opposé à la chambre de combustion, ainsi que respectivement un dôme de bougie d'allumage dont l'orifice (18, 20, 22) conduit à la chambre de combustion du cylindre correspondant. Selon l'invention, une structure nervurée (76, 80, 82) est intégrée dans le carter de culasse afin de rigidifier le carter de culasse (10) et/ou de supporter les calottes de chambre de combustion (64, 66, 68).
