Definitions

  • the invention relates to an internal combustion engine according to the features of Preamble of claim 1.
  • oil and / or water-carrying channels are integrated in the component carriers, so that, for example, that extracted from an oil pan by a lubricating oil pump Lubricating oil via the oil filter, the oil channels integrated in the console and via the Crankcase integrated oil channels for consumers, such as the main camps of the Crankshaft or the camshaft bearings is supplied.
  • Lubricating oil via the oil filter
  • Crankcase integrated oil channels for consumers, such as the main camps of the Crankshaft or the camshaft bearings
  • the object of the invention is therefore to provide measures which ensure that despite certain installation or manufacturing tolerances in the various components of the Internal combustion engine reliably integrated fluid-carrying components against each other are sealed.
  • a reliable seal of the oil channels to be connected results if At least one annular groove is arranged in the channel of the connecting piece, into which an O-ring for radial sealing against the neck of the console is inserted and on the front of the connecting piece, another O-ring received in an annular groove is provided, which seals the oil channel axially with respect to the crankcase.
  • the connecting piece attached to the crankcase points to support the console a contact surface on which there is an axially adjustable and fastened in the console Compensating element supports.
  • 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 oil required for the supply of lubricating oil 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 double 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.
  • a bracket 25 is attached, which in the present Embodiment includes an oil filter 26 and an oil / water heat exchanger 28.
  • the console 24 are integrated oil channels 30, which from the lubricating oil pump 10 first oil collecting space 12 extracted lubricating oil in the crankcase lower part 8 Forward integrated oil channels 32.
  • the lubricating oil reaches the oil channel 32 Main bearings of the crankshaft or to those in the cylinder head of the internal combustion engine arranged camshaft bearings.
  • the lubricating oil pump 10 has a pressure outlet 34 on which an oil duct 30 integrated into the console 25 leading connector 36 is connected.
  • the console shows on the output side 25 a nozzle 38 in which a part of the oil channel 30 is formed.
  • connection stub 42 On the Stub 38 of the bracket 25 is a connection stub 42 provided with a channel 40 placed.
  • the connecting piece 42 is attached to the lower crankcase part 8 and represents the transition from the oil channel 30 integrated in the console 25 to the in Lower crankcase part 8 integrated oil channel 32 safely.
  • the channel 40 of the Connection piece 42 two ring grooves 44 and 46, in each of which an O-ring 48 and 50th is inserted.
  • the two O-rings 48 and 50 radially seal the connecting piece 42 opposite the nozzle 38 of the console 25; at the same time with the help of Connection piece 42 possible axial tolerances in the distance between Crankcase lower part 8 and console 25 are compensated, since the connector 38 in Channel 40 of the connecting piece is displaceable.
  • an annular groove 52 is arranged coaxially to the channel 40, into which an O-ring 54 is also located is inserted; this seals the oil channel 30 axially with respect to the crankcase lower part 8 from. Since the diameter of the annular groove 52 is larger than the diameter of the im Crankcase lower part 8 integrated oil passage 32 is selected, possibly Tolerances occurring in the radial direction can also be compensated.
  • the Connection piece 42 also has a contact surface 56 on which one in the Console 25 fastened and axially adjustable by means of a thread Compensation element 58 for supporting the bracket 25 is present.
