Definitions

  • the invention relates to a cylinder head cover with intake manifold according to the preamble of claim 1.
  • An internal combustion engine is known - DE-AS 23 39 356 - in which the intake manifold system and the cylinder head cover are structurally combined.
  • This unit is rigidly attached to the cylinder by means of screws.
  • This embodiment has the disadvantage that the internal combustion engine emits disturbing noises via the unit, particularly because of the latter rigid type of fastening.
  • the wall of the cylinder head cover facing the cylinder head is continuously subjected to hot oil from the cylinder head during operation of the internal combustion engine, which leads to undesired heating of the intake manifold system and consequently reduced filling of the cylinders connected downstream.
  • the object of the invention is to attach the cylinder head cover assembly with the intake manifold to the cylinder head in such a way that noise emissions are reduced. However, it should also be ensured that heating of the intake pipe by spray oil from the cylinder head is avoided.
  • the main advantages achieved by the invention are the fact that the assembly consisting of the cylinder head cover and intake manifold is kept decoupled by the resilient elements on the cylinder head, whereby a significant noise reduction of the internal combustion engine is achieved.
  • These screws are screwed into the fastening screws of the multi-part cylinder head, which on the one hand ensures that the structural unit is held securely and on the other hand minimizes the mechanical effort for tapped holes in the cylinder head.
  • the fastening screws are easily manufactured automatic parts.
  • the cover between the cylinder head and the wall of the cylinder head cover which forms part of the intake manifold system and prevents it from undesired heating of the intake manifold system, so that the filling of the cylinders, which are fed by the intake manifold system, is of high quality.
  • the cover is a simple component, the assembly of which is easy with the seal between the cylinder head cover and the cylinder head.
  • the internal combustion engine 1 is multi-cylinder, operates in the four-stroke process and comprises a cylinder head 2 with a cylinder head cover 3.
  • the cylinder head 2 is in several parts, i.e. it is formed by a lower part 4 and an upper part 5 (also called camshaft housing); both parts 4 and 5 are assembled in a parting plane 6 which extends at right angles to a longitudinal center plane A-A of the internal combustion engine 1.
  • camshafts are indicated, which actuate two intake valves and two exhaust valves per cylinder, which is not shown.
  • the cylinder head cover 3 forms a structural unit 10 with an intake manifold system 9, i.e. the intake manifold 9 is made in one piece with the cylinder head cover 3.
  • the intake manifold 9 comprises a collecting space 10 'and a pipe part 11 which extends across the cylinder head 2 and which extends in an arc shape to a plane 12 which runs parallel to the parting plane 6.
  • the pipe part 11 is connected to a right-angled pipe bend 13, which is fixedly connected to the cylinder head at 14.
  • the pipe part 11 and the pipe bend 13 - which form almost a 180 ° bend - are connected to one another by means of an elastic member 15 which is designed in the manner of a sleeve.
  • a sleeve of this type is described in DE-P 36 41 811.
  • the cylinder head cover 3 of the assembly 10 which has an approximately U-shaped cross section, is connected to the cylinder head 2 or its upper part 5 in a parting plane 16 which runs parallel to the parting plane 6.
  • a seal 17 is between the cylinder head cover 3 and the upper part 5 of the cylinder head 2 arranged; it is effective between legs 18, 19 of the cylinder head cover 3 or webs 20, 21 of the upper part 5.
  • Screws 22, 23, which are arranged at a distance from one another, are used to hold the assembly 10 on the cylinder head 2, specifically outside the legs 17, 18, these screws being oriented perpendicular to the parting plane 16.
  • the screws 22, 23 have heads 24, 25 which tension resilient elements 26, 27 and 28 (FIG. 2) against supporting parts 29, 30. Thanks to this measure, the structural unit is kept decoupled from the cylinder head 2.
  • the resilient elements 26, 27 are helical springs which are subjected to pressure;
  • the elements 28 are rubber springs which have a rubber body 31 and metallic support parts 32, 33 which partially surround this.
  • the screws 22, 23 are aligned coaxially with fastening screws 34, 35 and screwed into threaded bores 36, 37 of the heads 38, 39 of said fastening screws.
  • the fastening screws 34, 35 hold the multi-part cylinder head 2, which consists of lower part 4 and upper part 5, in position.
  • the support parts 29 are provided on local fastening eyes 40 which are circular cylindrical in cross section and are molded into the structural unit 10.
  • the support parts 30 are laterally flanged away from the cylinder head cover 3.
  • the support parts 29, 30 lie on a common plane 41 which runs parallel to the parting plane 6.
  • the cylinder head cover 3 Adjacent to the parting plane 16, the cylinder head cover 3 has a wall 42 which extends between the legs 18, 19 and is part of the tube part 11 of the intake manifold system 9. A cover 43 is provided so that this wall is protected against hot spray oil from the cylinder head.
  • the cover 43 is a flat plate 44 which is connected to the seal 17 and extends along the parting plane 16; the space 45 inside the cylinder head cover 3 is therefore sealed off from the cylinder head 2.
  • the plate 44 which consists of thin-walled sheet metal, is provided with bead-like stiffeners 46; the plate 44 is thus a relatively rigid frame.
  • the edge 47 of the plate 44 becomes fork-like from the seal 17 encompassed. In this way, the plate 44 acts as a reinforcing metal insert for the seal 17.
