Definitions

  • the invention relates to an internal combustion engine having a cylinder head and a cylinder block, wherein a crankcase is attached to the cylinder block, wherein the crankcase has at least one oil pump.
  • head-cylinder block units are also referred to as a monobloc.
  • the head-block unit usually includes a one-piece crankcase.
  • internal combustion engines with multi-part crankcases are known, wherein in each case a crankcase part and bearing bracket for the crankshaft bearing are molded together in one piece. This component is also referred to as a "bed plate”.
  • monoblock internal combustion engines individual storage chairs have been used with individual bearing brackets to allow the necessary accessibility for the machining of the cylinder bores.
  • the object of the invention is to reduce the processing effort in an internal combustion engine of the type mentioned.
  • a simple attachment with little processing effort can be achieved if the flange is connected to the mounting wall via at least a first screw and the oil pump to the flange via at least a second screw, wherein preferably the second screws are longer than the first screws.
  • the oil pump is arranged on an inner surface of the mounting wall, wherein preferably the flange is arranged on an outer surface of the mounting wall, wherein the first and second screws can be inserted into corresponding screw holes from the flange side.
  • the oil pump is attached via the flange on the second part of the crankcase.
  • This flange is formed so that the first screws for the pump and the second screws for the flange are on the same side, namely the outside of the crankcase.
  • the flange is pressed onto the clamping surface of the first part of the crankcase with the short first screws and the oil pump is pulled by the long second screws onto the face of the flange.
  • the processing cost can be significantly reduced.
  • the crankcase consists of a subsequent to the head block unit first part and a subsequent to the first part of the second part, wherein the first and second part in a the axis of a crankshaft-containing plane, preferably normal to the Cylinder axes are divided, preferably first and / or second part forming at least one main bearing for the crankshaft.
  • the oil pump is arranged in the second part of the crankcase. Alternatively, however, an arrangement in the first part is possible.
  • FIG. 1 shows an internal combustion engine according to the invention in a section along the line I-I in FIG. 2;
  • Fig. 2 shows the internal combustion engine in a section along the line II-II in
  • Figure 5 shows the internal combustion engine according to the invention in a section along the line V-V in Fig. 1.
  • Fig. 6 shows the internal combustion engine in a view according to the line VI-VI in
  • FIGS. 1 to 4 show an internal combustion engine 1 with a cylinder head 2 and a cylinder block 3, wherein the cylinder head 2 and cylinder block 3 are made in one piece with a head block unit 4.
  • a crankcase 10 which consists of an upper first part 7 and a lower second part 8.
  • the cylinder liners 9 are screwed into the head block unit 4. Alternatively, it is also conceivable to form the cylinder liners 9 integrally with the head block unit 4.
  • Head block unit 4, first part 7 and second part 8 of the crankcase 10 may be made of different materials.
  • a particularly lightweight crankcase 10 can be realized when all components are made of light metal.
  • the distance between the individual cylinders results from the condition that a complete mounting bevel 13 must be formed for the O-ring seal 11 of the cooling water chamber 12. In the case of the integral cylinder liner, the cylinder pitch becomes smaller.
  • the two-part crankcase 10 may accommodate at least one mass balance shaft 20, at least one injection pump drive shaft, and / or at least one oil pump 30.
  • the outlet conduits 14 can be integrated into the head block unit 4. Furthermore, at least partially, the inlet lines 15 and the inlet header 16 can be integrated into the head block unit 4. Particularly in the case of a gasoline engine, long supply pipes 17 (“ram pipes”) may be accommodated in the cylinder head cover 18 and the head block unit 4. The inlet header 16 is in this case at a lower position.
  • ram pipes long supply pipes
  • the mass balance shaft 20 can be integrated into the first part 7.
  • the position of the mass balance shaft 20 is found so that the balancing weights 21 of the mass balance shaft 20 can rotate with sufficient distance from the envelope 22 of the connecting rod not shown, wherein the axis 20a of the mass balance shaft 20 is not necessarily in the plane ⁇ of the axis 19a of the crankshaft 19 must lie.
  • the bearing bores 23 are accommodated in flange bushings 24. These are fastened with flange screws 25 in the first part 7.
  • a trained as a dowel pin first pin 26 on the straight connecting line 27 between the axis 19a of the crankshaft 19 and the axis 20a of the mass balance shaft 20 is respectively at a precisely defined distance to the axis 19a of the crankshaft 19 in the region of the end faces 5 of the first Part 7 arranged.
  • the first pin 26 is guided in a bore 6 of the flange bushing 24 and holds the necessary distance for the engagement of the two gears 28, 29 for driving the mass balance shaft 20 through the crankshaft 19th
  • the machining of the surface 30 for the attachment of the Flanschbuchsen 24 in the first part 7 can be done from the outside.
  • a corresponding recess 31 for receiving the flange bushings 24 is provided in the head block unit 4.
  • a second pin 32 is provided with two flattenings 33 in its cross section in order to ensure the parallelism of the mass balance shaft 20 to the crankshaft 19.
  • the two flats 33 are aligned parallel to the connecting line 27 between the axis 19a of the crankshaft 19 and the axis 20a of the mass balance shaft 20.
  • the flange bushing 24 has a guide opening 39 corresponding to the second pin 32. As a result, the flange bush 24 can be pivoted about the first pin 26 without disadvantages for the tooth engagement of the two gears 28, 29 occur.
  • the receiving bores 34 for the main bearings 35 of the crankshaft 19 and the bearing bores 23 in the flange bushings 24 can be processed independently of the head-block unit 4 in one clamping.
  • the drive of the mass balance shaft 20 can be made instead of the gears 28, 29 with a chain.
  • the mass balance shaft 20 can also be designed to drive an injection pump 36.
  • the mass balance shaft 20 has for this purpose a cam 37, which acts on the drive plunger 38 of the injection pump 36.
  • the position of the cam 37 is freely selectable and, as an alternative to the symmetrical arrangement shown in FIG. 5, can also be provided in the area of the flywheel-side bearing.
  • an oil pump 40 can also be arranged in the crankcase 10, that is to say either in the first part 7 or in the second part 8.
  • Fig. 7 shows an embodiment in which the oil pump 40 is positioned in the second part 8.
  • the drive of the oil pump 40 via the crankshaft 19 through the drive gear 41.
  • a flange 43 is inserted into a mounting wall 42 of the second part 8.
  • the flange 43 is fastened via short first screws 44 to the mounting wall 42 of the second part 8.
  • Long second screws 45 pull the oil pump 40 against the front side 46 of the flange 43.
  • the oil pump 40 is not pressed by internal screws to the second part 8, but by the outer second screw ben 45 pulled against the end face 46 of the flange 43.
  • the screws 44, 45 for the attachment of the flange 43 and the oil pump 40 are arranged on the same externally accessible side of the crankcase 10.
  • the drive of the oil pump 40 may alternatively take place via the drive gear 41 via a chain, not shown.
