Definitions

  • the invention relates to a ventilation device for Vent gases from the crankcase of an internal combustion engine according to the preamble of claim 1.
  • DE 31 28 470 A1 describes a generic ventilation device known for a crankcase of an internal combustion engine.
  • An oil separator is arranged in the cylinder head cover, from which an oil drain pipe goes off, into one in the cylinder head immersed arranged oil collection space.
  • the ventilation gases pass from the crankcase of the Internal combustion engine via ventilation lines in the oil separator.
  • the separated oil runs through the oil drain pipe into the Oil collecting space, over the overflow of which the oil then enters the Oil pan of the internal combustion engine arrives.
  • DE 41 18 557 A1 describes a ventilation device Known in the two with respect to the cylinder head cover Oil separator with opposite longitudinal axis of the engine Sumps are integrated, each of which is a siphon-like Branch pipe branches to the camshaft space. In the Venting the vent gases get out of the crankcase via the camshaft chamber into the oil separator. The secluded Oil runs into the drip pans and flows through the pipe sockets into the camshaft space. From there it gets over one Oil return drained down. The de-oiled ventilation gases are then fed to the intake system of the internal combustion engine.
  • the invention has for its object a ventilation device to create their siphon with inexpensive manufacture and simplified installation, no additional installation space is required.
  • An essential advantage of the invention lies in the small space requirement the ventilation device according to the invention and thus achievable lower installation space height of the motor.
  • the the Oil level element of the siphon forming trough is by an anyway required countersunk hole of a cylinder head screw is formed, so that neither an additional trough is produced nor an additional one Installation space must be made available.
  • the cylinder head cover can be made as flat as possible.
  • the Countersunk hole forms a sufficiently large oil collection volume, that constantly replenished from the oil draining from the oil separator is achieved, whereby a good siphon effect is achieved.
  • the design of the siphon according to the invention is not complex Manufacturing processes, such as bending processes, necessary. Because when installing the cylinder head cover on the cylinder head the inlet pipe arranged in the cylinder head cover inevitably dips into the countersunk hole in the cylinder head, assembly of the venting device is also simplified.
  • the inlet pipe is expediently connected to the in the cylinder head cover integrated oil separator and is thus cast already taken into account when casting the cylinder head cover. On Subsequent mounting of the inlet pipe is therefore unnecessary. Alternatively, press the inlet pipe into the oil separator imaginable.
  • the cover part of the oil separator is advantageously diagonal to the engine longitudinal axis, in the direction of the inlet pipes Guide ribs on the oil separated in the oil separator leads directly to the inlet pipe of the siphon.
  • the oil separator preferably also has a diagonal in the lower part weirs running to the longitudinal axis of the engine, which prevent that separated oil is drawn towards the air outlet.
  • FIG. 1 shows a ventilation device 1 for a crankcase 2 of an internal combustion engine partially shown with rows of cylinders arranged in a V-shape, of which only here a row of cylinders is shown.
  • the venting device 1 can also be arranged in rows in internal combustion engines Cylinders are used.
  • On the crankcase 2 is about 3 cylinder head screws in countersunk holes 4 a cylinder head 5 attached by a cylinder head cover 6 is covered.
  • the ventilation device 1 has one with an intake system 7 of the internal combustion engine connected vent line 8, one arranged in the course of the ventilation line 8 and into the cylinder head cover 6 integrated oil separators 9 and a siphon 10 on.
  • the vent line 8 is in a not shown Way connected to the crankcase of the internal combustion engine.
  • vent gases from the crankcase 2 derived and fed to the oil separator 9.
  • the in the Oil particles entrained in ventilation gases separate in the oil separator 9 and are not over the siphon 10 here shown, arranged in the cylinder head 5 and in the crankcase 2 Oil return fed through which the oil is also in a Oil pan, not shown, at the lower end of the crankcase 2 is traceable.
  • the de-oiled vent gases are the intake system located after the oil separator 9 7 fed to the internal combustion engine and then the motor Combustion mixed. 1 and 2 is included the breather flow with solid arrows and the oil return shown with dashed arrows.
  • the siphon 10 contains an inlet pipe 11 and an oil level element 12, the oil level element 12 being arranged in the cylinder head 5 Includes trough 3, which can be drilled or cast. in the present embodiment, the trough is expedient through the countersunk hole 3 for the cylinder head screw 4 formed.
  • the inlet pipe 11 of the siphon 10 is on the oil separator 9 attached, preferably cast on the oil separator 9 or also pressed into the oil separator 9, and dips according to the invention into the countersunk hole 3 for the cylinder head screw 4, the counterbore 3 also being cast can be.
  • what is deposited in the oil separator 9 arrives Oil through the inlet pipe 11 of the siphon 10 into the counterbore 3 of the cylinder head screw 4.
  • the siphon 10 is the oil return upstream, via which the oil via the cylinder head 5 and the crankcase 2 into the oil pan at the lower end of the crankcase 2 is returned.
  • Fig. 2 several inlet pipes 11 over the length l of the oil separator 9 distributed.
  • the countersunk hole 3 enables sufficient Length of the siphon 10 in which the draining oil collects and a liquid barrier, pressure equalizing Oil column builds up that an unwanted flow of the ventilation gases prevented by the inlet pipe 11 in countercurrent to the oil. Since the countersunk hole 3 constantly from the oil separator 9 after flowing oil is filled, the excess occurs Oil over an upper edge of the counterbore 3 in the Oil return on.
  • Fig. 2 shows a part of the integrated in the cylinder head cover 6
  • Oil separator 9 the one of the intake system 7 of the Internal combustion engine side 13 of the cylinder head cover 6 runs in the direction of an engine longitudinal axis 14.
  • the oil separator 9 comprises an integral part of the cylinder head cover 6 Lower part 15 and a cover part covering the lower part 15 16.
  • the oil separator 9 is designed as a volume separator, which is reassuring over large cross sections and long distances of the oily vent gas and thus an oil separation enables.
  • the lower part 15 and the cover part 16 form one box-shaped housing in which baffles 15a are arranged are that the vent gas stream entering the oil separator 9 is deflected several times, the impact surfaces 15a an inclination to a drainage channel running in the lower part 15 15b.
  • the oil particles in the ventilation gases meet the baffles 15a, strike there down and flow into the feed pipes via the drainage channel 15b 11 of the siphon 10.
  • the inner walls of the oil separator 9 are as possible rough to ensure good adhesion of the oil droplets to be separated to reach.
  • the cover part 16 has a first air outlet arranged at the rear 17 mainly for full load ventilation and a second, laterally arranged air outlet 18 mainly for Partial load ventilation, both in the intake system 7 of the Internal combustion engine open.
