Definitions

  • the invention relates to an internal combustion engine with a cylinder head, a crankcase and an oil pan of the type specified in the preamble of claim 1.
  • an internal combustion engine which includes, among other things, a cylinder head, a crankcase and an oil pan.
  • a chain drive for driving the camshaft is arranged on an end face of the crankcase which runs transversely to two longitudinal sides.
  • drive means for a water pump, an alternator and a radiator fan are also located on the end face, these drive means being designed as belt drives.
  • the chain drive is partially accommodated in the valve cover and the cylinder housing and covered in the remaining area by a suitably designed hood.
  • Such a hood extends to the edge of the oil pan, which protrudes beyond the front end of the crankcase.
  • Such a construction results in many sealing edges, so that a large number of sealing elements have to be provided.
  • the sealing of flanges on which three parts are joined is generally very difficult due to the different expansion coefficients and directions due to temperature effects.
  • the invention is therefore based on the object of developing an internal combustion engine of the generic type in such a way that a simpler and more reliable seal is achieved by means of fewer or simpler components.
  • the side wall sections form a control box with a recess on the cylinder head side and a recess on the oil pan side.
  • This design means that the cavity formed within the control box communicates with both the chamber in which the camshaft sprocket is located and the oil pan, which makes it easy to lubricate the chain drive and return the oil to the oil pan.
  • connecting webs are preferably provided, wherein a connecting web is arranged between the upper ends of the side wall sections, which delimits the recess on the cylinder head side, and a further connecting web is provided between the lower ends of the side wall sections, which delimits the oil pan-side recess.
  • the upper ends of the side wall sections and, if appropriate, the connecting web to run flush with a cylinder head flange surface of the crankcase, so that there is a uniform sealing frame for the corresponding sealing surface of the cylinder head.
  • the lower ends of the side wall sections and, if appropriate, the lower connecting web should also be flush with an oil pan flange of the crankcase, so that the sealing surface of the oil pan also lies in one plane.
  • the front ends of the side wall sections and optionally the connecting webs form a flat surface, so that the front opening of the control box can be closed by a simply designed cover, for example in the form of a plate.
  • crankcase 1 in a perspective view.
  • the crankcase 1 has four cylinder bores 2 arranged in series, which are surrounded by coolant channels 3.
  • the upper side 4 of the crankcase 1 is designed as a flange surface 5 for a cylinder head.
  • the lower side 6 of the crankcase 1 has a peripheral edge which serves as an oil pan flange 7.
  • An end 8 of the crankcase 1 on the rear side in the drawing is provided for mounting a transmission, while a chain or belt drive is installed on a front end face 9 as a drive for a camshaft becomes.
  • side walls 10 and 11 of the crankcase 1, which are designed according to the respective parameters resulting from the number and size of cylinders, the arrangement of cooling channels, the attachment of auxiliary units and the like.
  • side wall sections 12, 13 are molded, which protrude as an extension of the side walls 10, 11 from the end face 6 and form a control box 14, which surrounds the chain or belt drive.
  • a recess 15 on the cylinder head side is formed between the upper ends 12 'and 13' of the side wall sections 12, 13 and is delimited by a connecting web 16 which extends between the upper ends 12 'and 13'.
  • the upper ends 12 ', 13' of the side wall sections 12, 13 and the connecting web 16 run in alignment with the cylinder head flange surface 5 and form a uniform sealing surface frame with the latter.
  • An oil pan-side recess 17 is formed between the lower ends 12 ′′ and 13 ′′ of the side walls 12, 13 and is delimited by a connecting web 18 extending between the lower ends 12 ′′ and 13 ′′.
  • the connecting web 18 and the lower ends 12 ′′ and 13 ′′ run in alignment with the oil pan flange 7 and form with this a uniform sealing surface frame for the oil pan.
  • control box 14 is open to the front, which facilitates the accessibility of the chain or belt drive.
  • the control box 14 is covered on the front by means of a flat closure cover, not shown, for this purpose the front ends 19, 20 of the side wall sections 12, 13 and the connecting webs 16, 18 are in the form of a flat surface 21 educated.
  • the connecting webs 16, 18 not only serve as sealing surfaces, but also contribute to the further stiffening of the crankcase 1.
  • crankcase can also be cast with the control box closed at the front. This further reduces the number of parts and sealing surfaces required.
