Definitions

  • the invention relates to an internal combustion engine according to the features of Preamble of claim 1.
  • the object of the invention is that of an exhaust gas pump from the turbocharger return lubricating oil returned to the oil sump in such a way that even when driving downhill it is ensured that the oil enters the oil sump above the oil level.
  • An ascending channel integrated at least in the oil collecting housing ensures that that the lubricating oil extracted by the exhaust gas turbocharger suction pump also Descent of the motor vehicle above the oil level formed in the oil sump is returned.
  • the solution is simple and inexpensive because there are no additional externally arranged lines are required.
  • the oil is transferred to the oil sump relatively far from the main oil pump suction point; thus the returned Lubricating oil sufficient time for self-defoaming.
  • the oil collecting housing shown in Fig. 1, hereinafter referred to as oil pan 2 is in the assembled state with its flange surface 4 on a flange surface 6 Crankcase lower part 8, a so-called bedplate, attached.
  • a lubricating oil pump 10 designed as a double pump attached.
  • a first oil collecting space 12 is formed, in which the necessary oil for the lubricating oil supply accumulates in an oil sump.
  • an oil snorkel 14 is arranged over a first Oil suction line 16 to a suction side of a first pump stage of the lubricating oil pump 10 leads.
  • a second, rear oil collecting space 18 is formed, on the latter lowest point also an oil snorkel 20 is arranged, which is a second Oil suction line 22 with a suction side of a second pump stage of the lubricating oil pump 10 is connected.
  • a plastic insert 24 is inserted, the two Separates oil collection spaces 12 and 18.
  • the insert 24 serves as an oil barrier and also prevents the lubricating oil from running out when driving uphill the first oil collection chamber 12 in the crank chamber and / or in the second Oil collection chamber 18 can cross.
  • the lubricating oil is in the second oil collecting space 18 from the main bearings of the crankshaft and the lubricating oil from the ones not shown Spray nozzles for the piston cooling collected and via the second oil suction line 22 in promoted the first oil collection chamber 12.
  • the oil pump 10 is connected via a chain wheel 26, which in turn has a chain drive a crankshaft gear, not shown, is driven.
  • a turbocharger suction pump 28 is also flanged to the front of the oil pan 2, which is also driven by the sprocket 26.
  • the also as a double pump executed oil suction pump 28 has two oil return lines 30 and 32, which with an exhaust gas turbocharger 34 and 36 are connected.
  • the exhaust gas turbochargers 34 and 36 are in a known manner on the exhaust manifold (not shown) which as V - Engine trained internal combustion engine attached.
  • a riser 38 in the housing of the oil pan integrated the functioning of which is explained in more detail.
  • the riser 38 settles continues in a control box cover 40 of the internal combustion engine and has one Exit opening 42, which is far above that located in the oil collecting space 12 Oil sump is arranged. This is done via the return lines via the riser duct 38 30 and 32 extracted lubricating oil for the drive shafts of the two exhaust gas turbochargers 34 and 36 are returned to the oil collecting space 12 formed in the oil pan 2.
  • Oil pump 28 designed as a double pump has only one outlet on the pressure side on, which is connected to an oil inlet opening 44 of the riser 38.
  • the riser 38 opens out above the oil pan 2, it is ensured that also at Descent of the motor vehicle, the lubricating oil drawn off by the suction pump 28 emerges above the oil level which forms in the oil collecting space 12. So that can defoam this oil before it is sent to consumers via the main lubricating oil pump 10 is fed again.
  • the riser channel integrated on the front of the oil pan 2 38 is still a sufficiently wide distance from the suction point of the lubricating oil pump 10 ensured; This measure also ensures that the Exhaust gas turbochargers 34, 36 extracted lubricating oil enough time Has self-defoaming.
