Definitions

  • the invention relates to an internal combustion engine with a crankcase, in which a crankshaft is rotatably mounted, at least a connecting rod is articulated which carries a piston which in a cylinder tube covered by a cylinder head is movable is. with gas exchange valves embedded in the cylinder head with one exhaust pipe and one trained as charge air line Combustion air line connected are at the geodetically lowest point an oil trap has, which is designed as a tub.
  • Such an internal combustion engine with a combustion air line is known from DE-A 2 052 501.
  • This combustion air line is intricately shaped, so that the production costs are considerable is.
  • the flow conditions are due to this configuration not optimal. This shows the combustion air line a collector for liquid, which is essentially a triangular central expansion of the combustion air line is formed. Through this training, the flow conditions further adversely affected.
  • JP-A 57-193755 which has an intake line has a collecting part for condensed water. This is done by a special design prevents the condensation in a throttle chamber can penetrate.
  • the invention has for its object an internal combustion engine with a combustion air line to provide the previously avoids the disadvantages described and also for a largely oil-free combustion air supply to the individual Cylinders.
  • the Charge air line can be assembled from charge air line sections is. Especially with supercharged internal combustion engines it is observed that entrained via the crankcase ventilation Oil despite an oil separator not so far from the subsequent one compressed combustion air is excreted that in the subsequent charge air line no more oil separation he follows. Therefore, in particular in the case of a charge air line, there is an oil trap Can be used advantageously in the form of a tub.
  • the To assemble the charge air line from individual charge air line sections is especially for one made in several variants Internal combustion engine of a series advantageous if, for example different numbers of cylinders are to be realized.
  • the charge air line sections of two adjacent cylinders in a row and the corresponding opposite row of cylinders to connect a charge air line section, so that this charge air line section four cylinders supplied with charge air.
  • charge air duct sections for example an 8-cylinder version, a 12-cylinder version and the aforementioned 16-cylinder version with identical charge air duct sections will be realized.
  • the tub is out Sump sections corresponding to the charge air line sections composed. This training is suitable for a production technology simple and inexpensive to manufacture such a trained charge air line.
  • the tub sections point at their longitudinal ends bulkheads that match the contour correspond to the tubular charge air line.
  • the tub is in one piece with the Combustion air line manufactured and the cross-sectional area of the Pan forms an additional area to the cross-sectional area of the combustion air line.
  • the combustion air line is essentially tubular.
  • the tub is at least approximated trapezoidal, with their trapezoidal Side walls below the equatorial plane in a straight extension of the walls of the combustion air line.
  • the charge air line is geodetic
  • a cooling water pipe is integrally formed at the highest point.
  • the cooling water line is in accordance with the charge air line sections divided. Through this cooling water pipe respectively these cooling water pipe sections becomes the cooling water that via connectors from the cylinder heads of the internal combustion engine is introduced into this line to a cooling water heat exchanger returned.
  • the combination of the cooling water pipe with the charge air line thus contributes to a further reduction the construction and manufacturing costs of the internal combustion engine at, since the cooling water comes from the same cylinder heads that Conversely, it must be supplied with charge air got to.
  • the cooling water line closes directly to the charge air line so that both lines have a common one Have partition.
  • This training ensures a further manufacturing technology and also inexpensive design.
  • Charge air line and the cooling water line in one piece, but not train with a common partition. Through this Design is a thermal insulation of both lines achieved, which may be necessary in certain applications.
  • the tub has an end face End externally accessible indentations on the insertion of Fastening screws in the recessed in the bulkhead Allow mounting holes. Furthermore, in the opposite front end of the tub in there Bulkhead opposite the mounting holes Blind hole thread inserted.
  • This training enables in the Area of the tub a very space-saving and the outer contour of the Charge air line with the tub in this area is not enlarging Fastening possibility by the functionality the reduced cross-sectional area is not a disadvantage. This can the charge air line with the tub through this optimized design deep into the v-space between the two rows of cylinders one V-type internal combustion engine. This will total the overall height of the internal combustion engine is reduced.
  • the intake manifold which the charge air line with connect the intake ports of the individual cylinder heads, in one piece molded onto the cylinder heads and designed so that they under Insertion of an elastic round seal on the corresponding Place openings in the charge air line.
  • the charge air line 1 is in the V-space between the two rows of cylinders of a V-shaped design Internal combustion engine used.
  • the charge air line 1 is off individual charge air line sections 2 composed.
  • the individual charge air line sections have attachment pieces 3 on, are passed through the fastening screws with which the assembled to the charge air line 1
  • Charge air line sections 2 in the V-space of the internal combustion engine are attachable.
  • the internal combustion engine only has one partially shown crankcase 4 on the one Intermediate housing 5 is placed, the connection to one Cylinder head 6 produces.
  • In the intermediate housing 5 is in one Crankcase 4 ragedes cylinder tube 7 used with a circumferential collar 8 between the intermediate housing 5 and the Cylinder head 6 is clamped.
  • In the cylinder tube 7 there is a piston 9, which is connected to a crankshaft via a connecting rod, is movable.
  • the cylinder tube 7 is in the one surrounded by the intermediate housing 5 Area coolable by cooling water, the cooling water from the Intermediate housing in the cylinder head 6, which is also to be cooled is forwarded. From the cylinder head 6, the cooling water is on the highest point through a pipe section 11 in a above the Charge air line 1 arranged cooling water line 10 passed.
  • the exemplary embodiment according to FIG. 1 is the cooling water line 10 spacing feet 12 in one piece on the charge air line 1 arranged. According to an embodiment not shown, it is but also provided the cooling water line 10 with omission the feet 12 to be placed directly on the charge air line 1, so that the both lines have a common partition.
  • the Charge air line 1 also has charge air connections 13 which are connected to Connection piece 14 to the intake ports of the cylinder heads 6 work together. These connecting pieces 14 are under insertion an elastic seal 15 without further screwing on the Charge air connections 13.
  • a trough 16 is also formed on the charge air line 1 geodetically lowest point of the charge air line 1 is arranged.
  • the Trough 16 has a substantially trapezoidal shape, wherein the shorter one at its geodetically lowest point Has trapezoidal legs.
  • the tub 16 catches that in the Charge air line 1 excreted oil that is on the walls settles on. This oil can then be collected in a suitable form be dissipated.
  • the Trough area, the cross-sectional area of the charge air line 1 is not influenced, in particular not reduced, so that a flow influence the charge air, for example by narrowing the cross-section is largely excluded.
  • the tub has bulkheads 17 which correspond to the contour of the tubular charge air line, that is, the bulkheads 17 point to the charge air line 1 circular arc training.
  • the individual charge air line sections 2 according to FIG. 2 instruct their front ends on flanges 18a, 18b, in the openings are inserted through which the charge air line sections 2 are screwed together. Similar flanges are on the Cooling water line 10 is provided.
  • the tub 16, however, instructs the front end 18b an externally accessible indentation 19 on the insertion of mounting screws into the Bulkhead allow 17 recessed mounting holes.
  • On the opposite ends 18a are in the bulkhead 17 blind hole threads opposite the mounting holes let in. The fastening screws are screwed into this.
