Definitions

  • the invention relates to an internal combustion engine with a venting device according to the preamble of patent claim 1.
  • crankcase ventilation for an internal combustion engine DE 197 09 910 A1
  • this crankcase breather is provided with a part-load breather and a full-load vent, and it has chokes.
  • DE 22 09 909 C2 a device for preventing lubricant losses in an exhaust gas turbocharger in which a vent line is provided between a lubricant space and a suction line.
  • the object of the invention is to make a venting device for an internal combustion engine with turbocharger simple, but highly effective.
  • the advantages achieved by the invention are to be seen in the fact that the combination of the crankcase breather and the turbocharger vent creates an excellently acting venting device of a turbocharged internal combustion engine which makes use of easily realizable throttles. Thanks to these chokes, the two modes, ie suction - negative pressure - and supercharger operation - pressure - taken into account in an advantageous manner, the smaller diameter of the second throttle ensures that the intended idle speed is maintained.
  • the chokes together with the distributor unit form a unit which can be produced in a simple manner.
  • the oil separator which cooperates with the venting device, can be assigned both to an oil reservoir of dry sump lubrication and to an internal combustion engine housing, eg cylinder head.
  • An internal combustion engine 1 comprises a crankcase 2 with integrated cylinders 3 and cylinder heads 4, 5.
  • the gas movements in a combustion chamber 6 of the internal combustion engine 1 are controlled by intake valves 7 and exhaust valves 8.
  • the intake valves 7 operate at an outlet 9 of a suction pipe 10; the exhaust valves 8 at an input 11 of an outlet conduit 12.
  • a fuel-air mixture igniting spark plug is referred to.
  • the intake pipe 10 has a first pipe section 14 and a second pipe section 15.
  • the first line section 14 supplies atmospheric fresh air to a compressor 16 of a turbocharger 17 which is provided with a lubricant of said turbocharger receiving oil reservoir 18.
  • the oil tank 18 is connected by a line 19 to a suction pump, not shown. From the compressor 16 pre-compressed air is conveyed into the second line section 15.
  • a throttle valve 20 is arranged, with a defined distance to the inlet valve 7 and exit 9.
  • the internal combustion engine 1 is provided with a venting device 21, which comprises a crankcase ventilation 22 for blowby gases and a turbocharger vent 23. Both have a constructive not closer executed oil separator 24 together, which is part of an oil container 25 of a dry sump lubrication in the embodiment.
  • a venting device 21 which comprises a crankcase ventilation 22 for blowby gases and a turbocharger vent 23. Both have a constructive not closer executed oil separator 24 together, which is part of an oil container 25 of a dry sump lubrication in the embodiment.
  • the oil separator into the internal combustion engine 1 and indeed into a valve cover 26 of the cylinder heads 4, 5.
  • the crankcase ventilation 22 for blowby gases and the turbocharger vent 23 are connected to a distribution unit 27, which is associated with the oil separator 24.
  • the distributor unit 27 comprises a first throttle 28 and a second throttle 29, whose smallest diameters DI and DII are of different sizes, namely DI> DII.
  • the diameter DI of the first throttle 28 is between 2.8 and 3.2 mm; the diameter DII of the second throttle 29 is 1.3 to 1.7 mm.
  • first throttle 28 with the interposition of the oil separator 24 by means of a first line 30, which is led away above an oil level 31 from the oil reservoir 25, to the first line section 14 of the intake passage 10, whereas the second throttle 29 by means of a second line 32nd is connected to the second line section 15 of the intake pipe 10.
  • the second line 32 in which a check valve 33 is connected, is connected between the throttle valve 20 and output 9 to the second line section 15 of the intake line 10.
  • a third line 34 of the crankcase ventilation 21 is laid between the cylinder head 4 and oil reservoir 25.
  • the line 34 discharges above the oil level 31 into the oil tank 25.
  • a fourth line 35 of the turbocharger vent 23 connects the oil tank 18 to the distributor unit 27; a fifth conduit 36 is required when the turbocharger vent is operative for two turbochargers as set forth in the exemplary embodiment.
  • the distributor unit 27, together with the throttles 28, 29, can be a prefabricated structural unit which can be fastened to the oil container 25.
  • the second line 32 is active, i. Venting medium enters via the third line 34 in the oil separator 24, from where it - largely exempt from the oil - passes through the first throttle 28 and the second throttle 29 in the second line 32.
  • the check valve 33 is opened, so that this medium is returned to the second line section 15 of the suction line 10.
  • corresponding medium passes via the fourth line 35 and the fifth line 36 and the second throttle 29 in the second line 32nd
  • the check valve 33 is locked due to the pressure prevailing in the intake line 7 overpressure conditions.
  • the venting media of the crankcase ventilation 22 and of the turbocharger vent 23 reach the oil separator 24 in the regenerated state via the first line 30 into the first line section 14 of the intake line 7.
