Definitions

  • the invention relates to an internal combustion engine with a ventilation device the preamble of claim 1.
  • crankcase ventilation for an internal combustion engine is known DE 197 09 910 A1, in the ventilation medium from a crankcase and a Cylinder head supplied to oil separators and freed of oil to an intake pipe is continued.
  • this crankcase ventilation with a Provided partial load ventilation and a full load ventilation, and it has throttles.
  • the object of the invention is a ventilation device for an internal combustion engine with turbo charging simple, but highly effective.
  • the main advantages achieved with the invention are that the Combination of the crankcase ventilation and the turbocharger ventilation excellent acting ventilation device of a turbocharged Internal combustion engine creates that uses easily realizable throttles. thanks to this Throttling is the two operating modes, i.e. Suction mode - vacuum - and Loader operation - positive 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 form together with the Distribution unit a construction unit that can be produced in a simple manner.
  • the oil separator the cooperates with the ventilation device, both an oil tank Dry sump lubrication, as well as an internal combustion engine housing, e.g. Be assigned to the 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 an intake line 10; the exhaust valves 8 at an inlet 11 of an exhaust line 12.
  • With 13 one in the combustion chamber 6 is a Fuel-air mixture called spark plug.
  • the intake pipe 10 has a first line section 14 and a second line section 15.
  • the first line section 14 leads atmospheric fresh air to a compressor 16 a turbocharger 17 which is lubricated with said turbocharger receiving oil container 18 is provided.
  • the oil container 18 is connected to a line 19 connected 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 inlet valve 7 or outlet 9.
  • the internal combustion engine 1 has a ventilation device 21 provided that a crankcase ventilation 22 for blowby gases and a Turbocharger ventilation 23 includes. Both do not work constructively with one executed oil separator 24 together, the component in the embodiment an oil tank 25 is a dry sump lubrication. But it is also conceivable the oil separator in the internal combustion engine 1 in a valve cover 26 To integrate cylinder heads 4, 5.
  • the crankcase ventilation 22 for blowby gases and the turbocharger ventilation 23 are connected to a distributor unit 27 which is assigned to 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 different in size, 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 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 above an oil level 31 from the oil container 25 is led away to the first line section 14 of the intake line 7 connected, whereas the second throttle 29 by means of a second Line 32 is connected to the second line section 15 of the suction line 7.
  • the second line 32, into which a check valve 33 is connected, is between Throttle valve 20 and output 9 to the second line section 15 of the Suction line 7 connected.
  • a third line 34 of the crankcase ventilation 21 is between the cylinder head 4 and Oil container 25 relocated.
  • the line 34 opens above the oil level 31 in the Oil reservoir 25.
  • a fourth line 35 connects the turbocharger ventilation 23 the oil tank 18 with the distributor unit 27; a fifth line 36 is then required if the turbocharger ventilation, as stated in the exemplary embodiment, for two turbochargers is effective.
  • the distributor unit 27 together with the chokes 28, 29 can be a prefabricated one Be assembly that can be attached to the oil tank 25.
  • the second line 32 active i.e. Vent medium enters the third line 34 in the Oil separator 24 a, from where it - largely freed of oil - via the first throttle 28 and the second throttle 29 reaches the second line 32.
  • the check valve 33 is open so that this medium in the first line section 14 of the Intake line 10 is returned.
  • Corresponding medium arrives at the same time via the fourth line 34 and the fifth line 35 and the second throttle 29 in the second line 32.
