Abstract

The engine has a cylinder crank casing, which is divided into upper and lower (10) parts and has main supports (12) in a separation plane for a crankshaft. The main supports are connected to a lubricant supply system, which has a lubricant supply opening (18) for each support. The lubricant supply opening is formed at the lower part next to a side (16) perpendicular to the separation plane and is connected to a lubricant supply channel (20). A bore (22) for each main bearing extends from a support surface (14) and is intersected by the lubricant supply channels.

Description

The invention relates to an internal combustion engine with a crankshaft and a Crankshaft-bearing cylinder-crankcase ZKG, the ZKG in the plane of the Crankshaft is divided into a ZKG upper part and a ZKG lower part and in this Partition plane main bearing for storing the crankshaft, which for lubricating the Bearing of the crankshaft are connected to a lubricant supply system, according to the preamble of claim 1.

In the case of high-speed, powerful internal combustion engines, one is to ensure sufficient lifespan in addition to very careful storage of the crankshaft an adequate, especially targeted supply of lubricant to their main bearings required. In the generic DE 22 57 651 C2 a corresponding Lubricant supply system for the main bearings of an internal combustion engine proposed in which a ring main line is formed within a bearing block from which the respective branch lines run to the storage areas of the main camps.

The present invention has for its object an internal combustion engine to improve the above-mentioned type with regard to the lubricant supply system.

This object is achieved by an internal combustion engine of the above. Kind with solved the features characterized in claim 1. Advantageous configurations the invention are specified in the dependent claims.

For this purpose, it is provided according to the invention that the lubricant supply system has the following:

  • 1. For every two main bearings, a lubricant supply opening, which is located on the ZKG Lower part laterally on a side perpendicular to the parting line between the two associated main bearings is formed.
  • 2. Two each connected to a lubricant supply opening Lubricant feed channels.
  • 3. One tap hole per main bearing, which from a bearing surface one respective main bearing, the lubricant supply channels such are arranged and designed so that they each cut a tap hole.

This has the advantage that the lubricant supply is simple is realized within the ZKG lower part, without the latter in size and exterior Form must be specially adapted to the lubricant supply. Furthermore the lubricant supply is independent of the design of the ZKG upper part.

For connecting the lubricant supply openings to a The lubricant supply system instructs the lubricant supply Oil supply pipe on which all lubricant supply opening together with a lubricant supply. For example, the oil supply pipe on the outside of the ZKG lower part and the lubricant supply opening flanged or molded to seal.

In a preferred embodiment, the lubricant supply openings are at ZKG lower part in an area below a crankshaft counterweight formed, the lubricant supply channels are parallel to the parting plane arranged, a central axis of the lubricant supply opening is parallel to the Partition plane arranged and the stitch holes are perpendicular to the parting plane arranged.

The fact that the lubricant supply channels within the ZKG lower part in such a way are designed so that they exist in the ZKG lower part Do not cut screw holes, a screw pattern of the ZKG lower part will not disturbed.

Further features, advantages and advantageous configurations of the invention result from the dependent claims and from the following description of the k Invention with reference to the accompanying drawings. These show in

The preferred embodiment of a cylinder crankcase (ZKG) lower part 10 shown in FIGS . 1 to 4 comprises a plurality of bearing shell supports 12 with bearing surfaces 14 for bearing shells (not shown) for a crankshaft (not shown) and is for forming the complete main bearing with one not shown ZKG top part connectable, which has corresponding bearing shell supports. A lubricant supply system is formed in the ZKG lower part 10 and comprises the following:

A lubricant supply opening 18 is formed on one side 16 of the ZKG lower part 10 for two bearing shells 12 or main bearings 12 , 14 of the crankshaft. Each lubricant supply opening 18 is connected to two lubricant supply channels 20 which run within the ZKG lower part 10 and which, in the top view or sectional view of FIGS. 1 and 3, extend obliquely away from the lubricant supply opening 18 in the direction of bearing shells 12 adjacent to this lubricant supply opening 18 . A tap hole 22 extends from the bearing surface 14 of each bearing shell 12 into the ZKG lower part. The branch bores 22 and the lubricant supply channels 20 are arranged and designed such that in each case one lubricant supply channel 20 intersects one branch bore 22 , so that a lubricant-conducting connection results from a lubricant supply opening 18 to two bearing surfaces 14 each.

As can be seen directly from FIG. 2, the lubricant supply channel 20 are arranged essentially parallel to a parting plane 24 between the ZKG lower part 10 and a ZKG upper part, not shown, while the tap holes 22 are formed perpendicular to the parting plane 24 . With reference numeral 26 are integrally cast extensions of the main bearing blocks 12, in 14 which make an oblique guide of the lubricant supply passages 20 of the lubricant supply holes 18 to underlying respective bearing surfaces 14 and to the branch holes 22 is possible.

As can be seen in particular from FIGS. 1 and 3, the arrangement of the lubricant supply channels 20 is selected such that a screw pattern is not disturbed, ie there is no need to adapt the arrangement of through holes for screw connections in the ZKG lower part to the lubricant supply system.

The apparent in particular from FIG. 4, the lubricant supply holes 18 are according to the invention connected to one of Figs. 5 to 10 visible in a preferred embodiment, the oil supply pipe 28, which is flanged to the side 16 of the ZKG- bottom part 10 such or a glove that the lubricant feed orifices 18 seals to the outside and connects with each other. For this purpose, the oil supply pipe 28 comprises three flange parts 30 , 32 and 34 , which are arranged on a pipe 36 at locations corresponding to the lubricant supply openings 18 of the ZKG lower part 10 .

As seen from Fig. 5, 6 and 9, the central flange portion 32, a central oil inlet 38 is formed. On the pipe 36 of the oil supply pipe 28 opposite this oil inlet 38 , a connecting piece 40 is formed for connection to the lubricant supply opening 18 in the middle in FIG. 4. Corresponding connecting pieces 42 , 44 are formed on the tube 36 on the flanges 30 and 34 for connection to corresponding lubricant supply opening 18 . The fact that the entire oil supply takes place through the oil supply pipe 28, which is separate with respect to the ZKG lower part 10 , simplifies the design of the lubricant supply system within the ZKG lower part 10 considerably, so that it does not in any way accommodate oil-guiding channels in its outer dimensions needs to be expanded. As a result, according to the invention, a simplified lubricant supply system with a constant ground clearance with respect to the ZKG lower part installed in a motor vehicle is achieved without having to forego a corresponding operational reliability of the lubricant supply.
