Definitions

  • the invention relates to an internal combustion engine with an oil separation chamber according to the preamble of claim 1.
  • the object of the invention is to provide an oil separation chamber in a cylinder head cover of an internal combustion engine, which ensures the separation of oil from an oil mist and a targeted drainage of oil into an oil collection container.
  • the main advantages achieved by the invention are that a so-called oil mist rising from the cylinder crankcase via openings in an oil separator plate can be deposited in the closed space of a cylinder head cover and the oil that separates out through labyrinthine channels delimited by guide ribs on the inner surface of the cover, drainage or Draining openings are supplied and the oil can drain into an oil collecting container.
  • the guide ribs which for this purpose have the greatest possible length in the hood cover, serve to separate the oil from the oil mist.
  • the drain of the oil to one side of the engine is made possible by the obliquely installed internal combustion engine, which is arranged transversely in the vehicle.
  • the air in the hood space is released to the outside through an outlet opening.
  • the air openings in the oil separating plate are preferably arranged in areas of the internal combustion engine which are low in splash oil. These are located around the edge of the hood in the raised section of the plate, in relation to the inclined installation position of the motor.
  • the two main longitudinally extending guide ribs each extend to both sides of the spark plug tubes, the lower guide rib having the drip openings, so that the oil collecting from the entire surface can be fed to the drain openings in the edge of the hood.
  • the longitudinal and transverse ribs are arcuate over sections and run into the walls of the spark plug tubes, so that there are smooth transitions and the oil is not inhibited in its flow.
  • Flow channels are provided between the outer and middle spark plug tubes, a transverse gutter being arranged as a flow channel between the two middle spark plug tubes.
  • the collecting trough has an outlet opening in the plane of the plate. On one long side, the collecting channel is delimited by a transverse guide rib, so that separate oil from one sector can be discharged in a targeted manner.
  • the air openings in the oil separating plate can be arranged over larger surface areas, these preferably being arranged between the side longitudinal walls and a longitudinal guide rib.
  • a cylinder head cover 2 is connected to a cylinder crankcase 1.
  • the motor has an inclined installation position in an inclined plane X-X.
  • An oil separating plate 3 is arranged in the cylinder head cover 2, which lies on the circumferential side on a circumferential projecting edge 4 and is fastened by means of screws 5.
  • the plate 3 is supported on projections 6 of spark plug tubes 6a to 6d.
  • the openings 8 are arranged in the raised portion of the plate 3 inclined in the plane X-X. These are immediately delimited by a first lateral hood longitudinal wall R1 and the guide rib 9. This forms a channel 17 in the longitudinal direction, which is delimited by transverse guide ribs 11 and 12 and the formation of flow paths 11a and 12a.
  • the second longitudinal guide rib 10 is arranged in the space 7 of the hood 2.
  • This forms channels 19, 20 between itself and the spark plug tubes 6a to 6d and a further channel 22 between the longitudinal wall R2 and the guide rib 10.
  • the channels 19 and 20 are separated by a transverse guide rib 13, whereas the longitudinal channel 22 has a transverse channel 21 is largely carried out continuously.
  • the guide rib 10 ends in an outer spark plug tube 6d. The oil is discharged via the drain openings 16 of the rib 10 via the drip openings 25 in the hood wall R2.
