Definitions

  • the invention relates to a device for venting a crankcase of an internal combustion engine and such an internal combustion engine with in particular V-shaped arrangement of the cylinder according to the features of the preambles of claims 1 and 7.
  • the object of the invention is to further improve the crankcase ventilation and the associated separation or separation of oil from the blow-by gases, in order ultimately to be able to lead the blowdown gases cleaned blowby gases back to the intake system of the internal combustion engine.
  • crankcase ventilation can be further improved.
  • the integrated in the component module ⁇ labscheidehunt can be designed larger volume; thus a longer venting path for the blowby gases can be implemented, so that the efficiency of the oil separation is further improved.
  • the opening cross section for the passage of the blow-by gases into the oil separation chamber is greater than the opening cross-section for the separated lubricating oil.
  • the return openings provided for the lubricant oil are easily monitored by valves. These release a connection to the cylinder head or camshaft space only when lubricating oil has accumulated in this area; The example mushroom-shaped valve then releases the opening and thus the return to the camshaft space due to gravity.
  • dividers are provided, which lead the blowby gas like a labyrinth from the inlet to the outlet; through this labyrinthine guidance of the blowby gases, the space in the oil separation chamber is optimally utilized; the associated extension of the way for the blow-by gases from the inlet to the outlet leads to a further calming of the blow-by gases and thus to a better separation of the lubricating oil.
  • the component module for oil separation has a trough-shaped body, which is closed by a separate lid.
  • a space-saving and suitable for a multi-row internal combustion engine with V-shaped arrangement of the cylinder arrangement for such ⁇ labscheidemodul arises when each component module between each cylinder head cover of an internal combustion engine and a centrally located in the interior of the two rows of cylinder air intake module is arranged.
  • the two oil separation chambers integrated in the oil separation modules communicate with each other via a hose line.
  • the pressure regulator is preceded by an additional oil separator, which is seen in the direction of flow of the blow-by gases, adjoins the oil separation chamber integrated in the second oil separation module and is combined with the pressure regulator together to form a structural unit.
  • the engine designed as a V8 engine has two rows of cylinder banks 2 and 3, both of which are integrated in a crankcase upper part 4 and adjoined by a crankshaft bearing bridge designed as crankcase lower part 5. Between the crankcase upper part 4 and the crankcase lower part 5, a crankshaft 6 is mounted accordingly.
  • the two rows of cylinder banks 2 and 3 have two cylinder heads 7 and 8, in which, inter alia, the inlet camshafts 9 and 10 required for controlling the intake and exhaust valves and the exhaust camshafts 11 and 12 are accommodated.
  • the intake camshafts 9, 10 and the exhaust camshafts 11, 12 are driven via a drive double gear arranged on the crankshaft 6 and a timing chain 14 formed as a continuous drive.
  • Both cylinder heads 7 and 8 are closed at the top by a respective cylinder head cover 16 and 18.
  • an air intake module 20 is arranged in the interior between the two rows of cylinder banks 2 and 3, in which eight individual intake pipes 22 are formed.
  • the combustion air is supplied to the individual cylinders via the individual intake pipes 22 via a central opening 24, which is formed on the front side on the air intake module 20 and to which a suction pipe, not shown, is connected.
  • a respective ⁇ labscheidemodul 26 and 28 is arranged, the structure and operation of which is described in more detail below.
  • the two ⁇ labscheidemodule 26 and 28 are integrated in a crankcase ventilation system, which in a known manner for the leadership in the combustion or the compression stroke in the Crankcase space of the internal combustion engine overflowing blowby gases to the outside or back to the intake system of the internal combustion engine is responsible.
  • the blowby gases flow from the crank chamber into the camshaft space 17 of each cylinder head 7 and 8.
  • the blowby gases are conveyed from the camshaft space 17 into the oil separation chambers 30 and 31 formed in the oil separation module 26 and 28, respectively, on a trough-shaped base body 32 and 34 each one - with respect to the longitudinal extent of the ⁇ labscheidemoduls 26, 28 formed in the substantially centrally arranged connection piece 36 and 38 which is inserted via two 0-ring seals 40 and 42 sealingly into an opening in the cylinder head cover 16, 18.
  • Both consisting of plastic ⁇ labscheidemodule 26 and 28 have a cover 44 and 46 which limits the ⁇ labscheidehunt 30 upwards and, for example. In friction welding on the base body 32, 34 is attached.
  • the ⁇ labscheidemodul 26, 28 is screwed by means of cover 44, 46 and body 32, 34 penetrating mounting screws 48 on the cylinder head cover 16, 18.
  • oil return ports 50 to 56 are in a first embodiment by mushroom-shaped valves 60 - whose operation will be explained later - monitored.
  • Trennleitwand 62 and 64 are integrally formed.
  • the separating guide wall 62, 64 encloses the inlet opening 66, 68 and extends in the direction of the two in the base body 32, 34 introduced oil return openings 50, 54.
  • the lid 44, 46 is, for example. In Reibschweisshabilit on the base body 32, 34 attached. On the inside of the lid 44, 46 is provided for the Trennleitwand 62, 64 a corresponding receiving groove.
  • the two ⁇ labscheidehuntn 30 and 31 are connected to each other via a hose 70.
  • a funnel-shaped spiral oil separator 72 is integrated, which communicates with the ⁇ labscheidehunt 31 on its input side and at its tapered end has a drain port 73 which is inserted into an opening of the cylinder head cover 18.
  • a pressure regulator 74 is placed, which possibly reduces the negative pressure in the crankcase space with respect to the prevailing in the suction negative pressure.
  • the pressure regulator 74 is closed at the top by a lid 75.
  • a line 76 is connected, which leads to the suction pipe (not shown) of the Lucasansaugmoduls 20.
  • the blow-by gases of the left and right bank of cylinder banks 2, 3 are guided into the oil separation chambers 30 and 31 via the connection ports 36 and 38 due to the negative pressure conditions prevailing in the intake pipe.
  • a part of the entrained by the blowby gases lubricating oil can be deposited, which in turn, in particular in the transient operation (accelerate, decelerate) via the oil return ports 50 to 56 in the camshaft cavities 17 back.
  • the valves 60 ensure that the openings are only released when due to the gravity of lubricating oil drops that have accumulated in this area, the valves 60 are opened.
  • blowby gases in the ⁇ labscheidehunt 30 are first guided by means of Trennleitwand 62 in the direction of the oil return port 50, and then deflected there, to flow through the entire length of the ⁇ labscheidehunt 30 and via the hose 70 into the ⁇ labscheidehunt 31.
  • the ⁇ labscheidehunt 31 via the connecting piece 38th introduced blowby gases analogous to the ⁇ labscheidehunt 30 through the Trennleitwand 64 and guided together with the transferred from the ⁇ labscheidehunt 30 blowby gases to the spiral oil separator 72.
  • Further purification of the blow-by gases takes place before the blow-by gases are returned via the pressure regulator 74 and via the line 76 into the intake tract of the internal combustion engine.
  • valves 60 shown in Fig. 6, which monitor the oil return or the oil return ports 50 to 56, as shown in the second embodiment of FIG. 7 and 8 - can also be dispensed with.
  • slit-like oil return openings 50 'to 56' are introduced at the front ends preferably slit-like oil return openings 50 'to 56' are introduced.
  • the openings 50 'to 56' are dimensioned so that it is ensured due to the adhesive forces acting between oil droplets and the edges of the openings 50 'to 56', that the openings 50 'to 56' are always closed by dripping oil, so that no Blowby gases can pass through these openings 50 'to 56' in the ⁇ labscheidehunt 30, 31.
