Definitions

  • the invention relates to a lubricating oil supply device for an internal combustion engine according to the features of the preamble of patent claim 1.
  • the oil cooler is a hydraulic resistance, which leads in particular at low oil temperatures to a corresponding pressure drop.
  • Downstream consumers e.g. hydraulically adjustable camshaft adjuster or a hydraulically actuated valve lift can be adversely affected due to insufficient oil pressure or amount of oil.
  • the object of the invention is to avoid such disadvantages.
  • the oil cooler is taken out as a significant hydraulic resistance from the main oil circuit and integrated into the second rear pump stage, the lubricating oil supply to consumers can be improved.
  • the power consumption of the two oil pumps can be reduced in total, if the second pump stage, a lower oil flow rate is promoted, since then according to the hydraulic Resistance of the oil cooler is lower.
  • the oil cooler is arranged on the pressure side of the second oil pump.
  • the two oil pumps are summarized in an advantageous manner to a double oil pump with two pump stages.
  • the oil conveyed back by the ATL oil suction pump into the first construction space section can also be cooled by the oil cooler in an advantageous manner.
  • the pressure side of the ATL suction pump opens upstream of the oil cooler in the (secondary) lubricating oil circuit of the second oil pump (second pressure stage).
  • the sole FIGURE shows a hydraulic circuit diagram of a supercharged dual-row eight-cylinder engine.
  • a crankcase (not shown) of an internal combustion engine and only schematically illustrated oil collection housing, hereinafter referred to as sump 2 has a front and rear space section 2a and 2b, hereinafter referred to as the first and second oil collection space are designated.
  • a suction pipe 4 and 6 is placed, which are connected on the suction side to each of an oil pump 8 and 10.
  • the two oil pumps 8 and 10 are summarized as a double oil pump with two pump stages, the first pump stage 8 is adjustable.
  • the lubricating oil collected in the rear oil collecting space 2b is pumped by means of the second pumping stage 10 into the first oil collecting space 2a.
  • the rear lubricating oil circuit designed as a plate heat exchanger oil cooler 12 is integrated, which ensures appropriate cooling of the lubricating oil.
  • the lubricating oil present in the first oil collecting space 2a is fed to the actual consumers of the internal combustion engine.
  • These include: the main bearings of the crankshaft 14, the bearings for the four camshafts 16, the piston spray nozzles 18 (4x) and the hydraulically actuated camshaft adjuster 20 provided for both cylinder bank rows on the inlet side and switchable tappet 22 for valve lift switching (so-called Porsche VarioCamPlus system).
  • the two cylinder heads supplied lubricating oil for the camshaft 16, the camshaft adjuster 20, the switchable tappets 22 and the valve clearance compensation elements 24 via first return channels 26 in the the first oil-collecting space 2a, while the lubricating oil provided for the main bearings of the crankshaft 14 and the piston-spraying nozzles 18 is returned to the rear oil-collecting space 2b via second oil-return passages 28.
  • the exhaust gas turbocharger 30 and 32 provided for each cylinder bank row is likewise supplied with lubricating oil via the first pressure stage 8 for lubricating the drive.
  • an oil-extraction pump 34 and 36 is provided which draws the lubricating oil from the so-called catch tank 38 and 40 and conveys it back into the first oil-collecting space 2a.
  • the lubricating oil delivered by the two ATL extraction pumps 34 and 36 is also cooled accordingly via the oil cooler 12.
  • a common pressure line 42 opens into the pressure line 44 of the second pump stage 10.
  • a safety valve 46 is provided, which releases a corresponding bypass line 48, if necessary.
  • a corresponding oil filter 50 is provided with a pressure relief valve.
