Definitions

  • the invention relates to a ventilation device for a crankcase an internal combustion engine according to the preamble of Claim 1.
  • a venting device is known from DE 196 07 919 A1, by means of which the oil particles in the oil-air mixture of a crankcase separated and returned to the oil pan.
  • the venting device comprises a centrifugal oil separator with a rotating housing that is several radial has extending inflow channels, which in a central, axial running outflow channel open.
  • the oil-air mixture will guided radially from the outside in through the inflow channels, in which obstacles are arranged, due to the by the rotational movement of the housing generated centrifugal forces the oil particles of the oil-air mixture are separated at the obstacles and against the inflow direction of the oil-air mixture are thrown radially outwards.
  • the one from the Air freed from oil particles is discharged via the outflow channel and the intake tract of the internal combustion engine.
  • This venting device has the disadvantage that on the one hand the oil-air mixture is fed radially from the outside inwards, on the other hand the separated oil particles radially in the opposite direction be dissipated from the inside out so that within the Inflow channel two opposing flows arise.
  • This has one limited efficiency of the ventilation device, both in terms of flow rate and also with regard to the degree of cleaning, because the opposite Currents hinder each other and at least partially one permanent mixing of both streams takes place.
  • one Increasing the speed of the centrifugal separator does not lead to anything better efficiency because with increasing rotation speed the outward oil particle flow the inward directional oil-air flow is increasingly entraining.
  • the invention is based on the problem of efficiency Venting device with a centrifugal oil separator to improve with simple means.
  • Another advantage is the axial entry of the oil-air mixture in the oil separator because the oil-air mixture before the Entry opening into the housing of the oil separator none or is subjected to low centrifugal forces and entry the flow into the housing is not hindered.
  • a cover attached to the crankcase provided that additionally supports the oil separator and also the interior of the crankcase flow-tight against the atmosphere concludes.
  • a feed channel is formed, which contains the oil-air mixture the inflow channel in the interior of the crankcase supplies.
  • This feed channel preferably describes a deflection of about 180 °, so that already on the inner wall of the feed channel a pre-separation of oil particles from the supplied Oil-air mixture takes place.
  • the outer wall of the inflow channel is expediently identical to a radial wall portion of the housing, the inflow opening of the inflow channel on an end face of the housing lies.
  • This version is characterized by a simple design with no specially designed outer wall is required for the inflow channel.
  • In the outer wall are advantageous Outflow holes introduced through which the separated Oil can drain off.
  • the inflow channel is preferably designed annularly around the Entry of the oil-air mixture into the housing over the entire To enable the scope of the housing. In this rotationally symmetrical Training can achieve the greatest possible throughput become.
  • the partition can on the End cover be rotatably mounted.
  • the baffles suitably arranged in the inflow channel can formed as webs projecting at an angle into the inflow channel be, in particular at least two consecutive Baffles are provided, which alternate, for example the outer wall and can be arranged on the partition, so that the inflowing mixture is redirected at least once and oil can deposit on the surfaces of the webs.
  • the figure shows a ventilation device 1 for ventilation of the oil-air mixture in a crankcase 2 one Internal combustion engine.
  • the venting device 1 comprises one Centrifugal oil separator 3, which rotates with a balance shaft 14 is connected and a cover 12 in Has wall area of the crankcase 2.
  • the oil separator 3 rotates at the same speed as the balancer shaft 14, the Oil separator and the balance shaft have a common Axis of rotation 5.
  • the oil separator 3 has an approximately cylindrical, multi-part housing 4, which consists of a pot-like Base body 15, a first annular body 16 and a second annular body 17, the first body 16 on the end face of the housing wall of the base body 15 and the second in a corresponding manner Body 17 placed on the first body 16 is.
  • the base body 15 and the two body parts 16, 17 form a unit and are held together captively.
  • an approximately sleeve-shaped Partition 10 is provided, which is in one piece with the first body 16 is formed.
  • a Inflow channel 6 is formed, which is substantially parallel to Axis of rotation 5 and with a radial offset to the axis of rotation 5, the inflow opening of the inflow channel 6 in the region an axial end face facing the end cover 12 of the housing 4 is.
  • the inflow channel 6 is annular constructed, the inflow opening extends accordingly on the axial face over 360 ° over the entire Scope. If necessary, instead of an annular Inflow channel also several, segment-wise over the circumference Distributed inflow channels can be arranged.
  • the cover plate 12 fixed to the crankcase 2 has an annular receiving groove 18 in which the free End face of the partition 10 is added.
  • a sealing ring 19 is arranged to the interior of the Oil separator flow-tight against the crankcase interior to complete and prevent incorrect air flows.
  • the face the partition 10 is rotatably received in the receiving groove 18.
  • In the end cover 12 there is an axial outflow opening 7 provided, through which the housing interior with the intake tract the internal combustion engine is connected.
  • a feed channel 13 formed over which the oil-air mixture from the Crankcase interior is passed into the inflow channel 6.
  • the feed channel 13 directs the axially flowing oil-air mixture by 180 ° and directs the mixture into the housing 4.
  • the feed channel is not necessary when the inflow opening of the oil separator on the opposite end cover opposite side is arranged.
  • baffles 11 are arranged, which are in shape of angled webs into the free flow cross section of the inflow channel 6 protrude. They are in the direction of flow several baffles 11 arranged one behind the other are provided, which expediently alternate from opposite Insert sides into the inflow channel.
  • a chicane 11 which is integral with the second body 17 of the housing 4 is formed in the inflow channel 6.
  • Another chicane 11 is on the Partition 10 attached.
  • the oil-air mixture is according to the drawn flow arrows several times by 180 ° in the inflow channel 6 deflected around the baffles 11.
  • outflow bores 9 introduced for separated oil, which is expediently even are distributed over the circumference of the outer wall 8, wherein axially both in the base body 15 and in the first body 16 and optionally also in the second body 17 outflow bores 9 are provided.
  • drain holes can also have openings of any cross-section, for example Column.
  • the outflow bores arrange the circumference unevenly.
  • the oil separation works as follows: The oil-air mixture from the crankcase interior flows in the direction of the entered flow arrows into the feed channel 13 and further into the inflow channel 6, the mixture being passed through the baffles 11 and separated on the walls of the baffles or on the inside of the outer wall 8 becomes.
  • centrifugal forces act on the oil particles, so that the oil particles are pressed against the inside of the outer wall 8 and flow radially outward through the outflow bores 9 back into the crankcase interior.
  • the flow is not impaired by the rotational movement, so that the clean air freed from the oil particles can enter the interior of the housing and leave the oil separator 3 via the outflow opening 7.
