Definitions

  • the invention relates to an internal combustion engine with at least two rows of cylinder banks according to the preamble of claim 1.
  • a device for crankcase ventilation is a known two-row internal combustion engine, in which on the cylinder head housing or Breather lines attached to the cylinder head cover in the crankcase area so-called blow-by gases and the suction system of the internal combustion engine in be returned to a closed cycle.
  • blow-by gases on the inside of the cylinder head cover, to which the blow-by gases flow past and part of the oil carried by the blow-by gases is deposited.
  • crankcase ventilation for to improve multi-row internal combustion engine in that at Crankcase ventilation effectively removes the carried oil from the blow-by gases and on the other hand the effort for externally routed ventilation lines is reduced.
  • crankcase ventilation should also when driving uphill or downhill Be ensured motor vehicle.
  • the oil separation chamber is integrated in the cylinder head cover so that the inlet opening for the blow-by gases essentially in the middle of the cylinder head cover, based on its longitudinal extension is arranged. This is also the case for ascents and descents Motor vehicle ensured that despite the located in the camshaft space Do not lubricate the crankcase ventilation through the oil separation chamber is impaired.
  • the oil separation chamber is advantageously constructed in two parts and consists of a bowl-like bottom part, which is completed by a cover element.
  • Another oil separator is provided on a cylinder head cover Direction of flow of the blow-by gases seen, to the second in the cylinder head cover integrated oil separation chamber.
  • a pressure regulator is attached to the oil separator, its output via a Connection line leads to the intake manifold of the internal combustion engine. So that in Depending on the load state of the internal combustion engine prevailing in the intake manifold Vacuum to a constant suitable for the crankcase ventilation Negative pressure value can be adjusted.
  • the internal combustion engine designed as a V8 engine has two rows of cylinder banks 2 and 3 on, both of which are integrated in a crankcase upper part 4 and to which one as Crankshaft bearing bridge designed crankcase lower part 5 connects. Between the crankcase upper part 4 and the crankcase lower part 5 is accordingly a crankshaft 6 is mounted.
  • the two rows of cylinder banks 2 and 3 have two Cylinder heads 7 and 8, in which, among other things, those for controlling the input or Exhaust valves required intake camshafts 9 and 10 as well as the Exhaust camshafts 11 and 12 are included.
  • the intake camshafts 9, 10 and the exhaust camshafts 11, 12 are arranged on the crankshaft 6 Drive - double gear and a control chain 14 formed as an endless drive, one so-called duplex chain, driven. Both cylinder heads 7 and 8 are up through each completed a cylinder head cover 16 and 18.
  • the one on the cylinder head cover 16 provided connector 32 forms the outlet opening for the oil separation chamber 20. How 2 can be seen, a vent or at the outlet 32 Connection line 34 connected, which leads to the cylinder head cover 18 and their the other end at an inlet connection 36 provided on the cylinder head cover 18 is attached.
  • the inlet connector 36 is arranged on the cylinder head cover 18 so that it directly next to the inlet opening 30 of the oil separation chamber 22 in the through the Cylinder head cover 18 opens the closed camshaft space 17.
  • the Oil separation chamber 22 is located above an outlet opening 38 with a spiral - Oil separator 40 in connection.
  • a pressure regulator 42 is located on the spiral oil separator 40 attached, which, if necessary, the negative pressure in the crankcase compared to that in the Suction system prevailing vacuum reduced.
  • the pressure regulator 42 has one Output nozzle 44, to which a line 46 is connected, to the intake manifold leads the suction system of the internal combustion engine, not shown.
  • Both oil separation chambers 20, 22 also have at their lid edges Openings 48 through which the lubricating oil located in the oil separation chamber 20, 22 can cross the camshaft chamber 17. Furthermore, in the Oil separating chambers 20 and 22 partition walls 50 (dashed lines) which act as a labyrinth shown). As can be seen in particular from FIGS. 5 and 6, the spaced between the two inlet openings 28 and 30, a separating rib 52 and 54, respectively intended. The two ribs 52 and 54 prevent the lubricating oil from on this The intended camshaft bearing height - supply of lubricating oil via openings 28 and 30 gets into the oil separation chambers 20 and 22. In the middle of the two Cylinder head covers 16, 18 each extend in the longitudinal direction Middle rib 56, 58.
  • blow-by gases of the left bank of cylinders 1 to 4 are due to the in the intake manifold prevailing vacuum conditions via the opening 28 into the oil separation chamber 20 guided.
  • a part of the blow-by gases can be in the oil separation chamber 20 entrained lubricating oil are deposited, which in turn in particular transient operation (acceleration, braking) via the openings 48 in the Camshaft space 17 returned.
  • the blow-by gases are then over the Connection or ventilation line 34 to the right bank of cylinders 5 to 8 in the Cylinder head cover 18 transferred. There they enter the camshaft space 17 and are via the opening 30 together with the blow-by gases from the right Row of cylinder banks led into the second oil separation chamber 22.
