Definitions
- the invention relates to an internal combustion engine with pressure circulation lubrication on the dry sump principle, in particular for a boxer engine according to the preamble of patent claim 1.
- an oil sump box attached to the sump cover is provided in the oil guide housing or in the oil sump, in which the oil sump is designed to supply the engine with lubricating oil is.
- the returned by the consumers in the oil pan lubricating oil is first returned outside of the ⁇ labsaugraum forming oil pan box before it passes through the monitored in ⁇ lschottkasten by flaps openings in the actual ⁇ labsaugraum.
- the oil flowing back into the sump is conveyed by a suction pump into a separate oil tank or reservoir. From there, the pressure oil feed pump sucks off the lubricant and pushes it over the filter and gff. Oil cooler to the lubrication points.
- the oil tank is in most cases attached to the outside of the engine housing and has appropriate connections for the externally installed oil pressure lines.
- the invention has for its object to increase the specific performance of an internal combustion engine to develop a low-friction engine with a dry sump - pressure circulation lubrication especially for high speed operation, in which the components required for the pressure circulation lubrication of the engine components are integrated in a space-saving manner largely in the engine.
- the lubricating oil from the annular spaces can pass directly into the oil collecting space (s). This can largely be dispensed with external oil lines, so that this measure contributes to a compact and inexpensive implementation of an internal combustion engine with dry sump lubrication.
- Fig. 1 is a dry sump oil circuit diagram of an internal combustion engine and Fig. 2 is a schematic representation of the oil return in the cylinder
- FIG. 1 shows the not limited to this embodiment principle of a dry sump - oil circuit diagram for a 6-cylinder boxer engine, whose only necessary for the description of the oil circuit components are described below with reference to the drawings.
- the engine has two crankcase halves 2 and 4, in each of which a row of cylinder banks 1 to 3 and 4 to 6 is arranged. To the two rows of cylinder banks is followed in each case by a cylinder head 6 and 8, in which the valve gear required for actuating the inlet and outlet valves is arranged.
- the crankcase 2, 4 has below the bearing for the crankshaft 10 to a (dry sump) ⁇ labsaugraum 12, in which the lubrication oil provided for the lubrication of the bearings is collected.
- integrated in the engine oil return holes ensure that the lubricating oil is purposefully returned to the ⁇ labsaugraum 12.
- Thensumpf- ⁇ labsaugraum 12 is limited by an oil bulkhead 14, on the two side walls 14a and 14b (wet sump) collecting spaces 16 and 18 adjacent. Both collecting chambers 16, 18 are connected to each other via a between the lower wall 14c of the oil pan 14 and a sump cover 20 forming gap 22 with each other.
- an oil return pump 24 is provided, on the suction side of which an oil suction line 26 is connected, which leads into the oil suction space 12.
- an ⁇ labsaugschnorchel 28 is attached, which is placed in the region of the lower wall 14 c of the oil pan 14.
- a line 30 is connected, which leads as a branch line 30a and 30b to a respective cylinder 1 to 3 and 4 to 6 surrounding annular space 32 and 34.
- the two annular spaces 32, 34 are each provided on their front side facing the crank chamber by a seal 36 (shown only in the left-hand crankcase half 2), eg in the form of plastic glasses, sealed.
- the annular spaces 32, 34 have openings 38 or openings at their lower lateral surfaces, which are in each case in communication with the (wet sump) collecting spaces 16, 18.
- the middle cylinder of the two rows of cylinder banks 1 to 3 or 4 to 6 has in each case a vent pipe 40, 42, which is connected to the - related to the installation position of the Zylinder ⁇ upper side of the annular spaces 32, 34.
- suction pumps 44, 46 are provided which suck the pumped from a main pump 48 into the cylinder heads 6, 8 lubricating oil and via lines 50, 52 and the annular spaces 32, 34 also in the (wet sump) collecting spaces 16, 18 return.
- the main feed pump 48 is driven via an intermediate shaft (not shown in detail), on whose suction side an oil suction line 58 is connected, which leads into the oil collecting space 16. At the end of the oil suction line 58, an oil suction snorkel 60 is again attached, which is placed in the vicinity of the sump cover 20.
- an oil suction snorkel 60 is again attached, which is placed in the vicinity of the sump cover 20.
- 4 integrated oil supply lines (not shown) connected to the consumers, such as. Main bearings of the crankshaft and the camshaft lead.
