Definitions

  • the invention relates to a device for media guidance in a cylinder crankcase of a reciprocating piston internal combustion engine with a plurality of cylinders, according to the preamble of patent claim 1.
  • Cross channels of the generic type are known in cylinder housings of internal combustion engines both for supplying lubricating oil and as cooling water guides for the cooling system in a large number of designs (cf. for example DE 43 41 040 A1 or DE 36 01 383 A1). Due to the limited space, the thinnest possible wall thicknesses of the cylinder housing and / or due to adjacent functional parts, these cross-channels are mostly complicated in terms of their geometry and flow cross-section.
  • the object of the invention is to provide a device of the generic type, which can be produced with a simple channel guide and a sufficiently dimensioned flow cross-section, even in a confined space.
  • the at least one transverse channel runs in a free space which is formed by recesses in two pistons which are adjacent to one another in the lower region of the piston shafts and above the crankshafts. shaft bearing of the internal combustion engine is formed.
  • the cross-channel can thus be designed with a larger diameter than the distance between the cylinders to one another (gusset distance), as a result of which the number of cross-channels can be reduced and / or the flow rate can be increased.
  • the transverse channel can preferably be used to guide the cooling water between cooling chambers of the internal combustion engine on both sides, although corresponding transverse channels can also be provided as an alternative or in addition for supplying lubricating oil to the internal combustion engine.
  • the transverse channel can be formed in a simple manner by a tube inserted into a transverse bore in the cylinder housing.
  • the machining of the cylinder running surfaces is simplified by the fact that the tube forming the transverse channel is only used after finishing the cylinder raceways or the entire cylinder crankcase and therefore does not impede the preceding machining steps.
  • the pipe passes through the ventilation openings.
  • the preferably thin-walled tube thus bridges these ventilation openings and enables an even more compact arrangement of the transverse channel.
  • the transverse channel can preferably be connected, on the one hand, directly to the water pump of the internal combustion engine via a feed line and thus effectively supply cooling water to the longitudinal side of the in-line internal combustion engine facing away from the water pump. Furthermore, the at least one transverse channel can run above a longitudinal channel of the pressure circulation lubrication system of the internal combustion engine arranged in the cylinder crankcase and thus reduce the production outlay while avoiding channel deflections. Both the transverse channel and the said longitudinal channel can be produced by correspondingly straight bores.
  • the transverse channel can also be particularly advantageously inclined such that it runs below the higher balancer shaft and above the lower second balancer shaft.
  • pistons can be so-called box-type pistons or slipper pistons, the piston shafts or piston shirts of which form corresponding lateral recesses in the region below the piston rings, only lateral guides of the pistons transverse to the longitudinal axis of the series internal combustion engine.
  • Flg. 1 shows a partial cross section according to line I - I of FIG. 2 through a cylinder housing of a four-cylinder inline reciprocating piston internal combustion engine with a transverse channel designed as a tube in the gusset area between two adjacent cylinders
  • Fig. 2 shows a longitudinal section along line II - II of Fig. 1 through the section shown cylinder housing.
  • Fig. 1 denotes a cylinder housing, shown in sections, of a four-cylinder in-line reciprocating piston internal combustion engine, which, if not shown and described, can be of a known type.
  • cylinders 12 are formed with corresponding running surfaces for pistons 14.
  • the pistons 14 are connected in a known manner to a crankshaft of the internal combustion engine via piston pins and connecting rods, not shown.
  • crankshaft is rotatably supported in the transverse walls 16 of the cylinder crankcase 10 and in corresponding end walls (not shown), with corresponding bearing seats 18 being incorporated into the transverse walls 16, which represent the main crankshaft bearing arrangement with screw-on bearing covers (not shown).
  • bearing points 20, 22 are provided in the cylinder crankcase 10 on both sides of the crankshaft axis of rotation or on the longitudinal sides, in which balancer shafts (not shown) are rotatably mounted to compensate for free mass forces or moments of 2nd order of the internal combustion engine.
  • the pistons 14 are designed as so-called box pistons, the piston shafts of which are provided with symmetrical recesses 14a below the piston rings (without reference numerals), so that the pistons 14 in their lower region only in the transverse direction (corresponding to the sectional plane of FIG. 1) in the cylinders 12 are led.
  • the cylinder walls 12a of the cylinders 12 end in the lateral regions of the pistons 14 with respect to the longitudinal direction of the cylinder housing 10, as can be seen in FIG.
  • the cylinder liners thus end in the region of the recesses 14a of the pistons 14 due to the ventilation openings 26 below the piston rings and in the region of the pistons 14 with respect to the transverse direction of the cylinder housing 10 approximately with the lower edge of the piston skirt, so that lateral guides of the pistons 14 only crosswise to the longitudinal axis of the cylinder housing 10 are formed.
  • the ventilation openings 26 provided in the transverse walls 16 of the cylinder housing 10 connect the crankcase spaces located between the transverse walls 16 of the cylinder housing 10 (which are delimited at the bottom by the oil pan, not shown) with one another for the purpose of pressure compensation.
  • a transverse channel 28 is provided, which is composed of a corresponding bore 30 in the cylinder housing 10 and a thin-walled tube 32, the tube 32 being inserted tightly into the bore 30. This can be accomplished by pressing in and / or by inserting appropriate sealing rings.
  • the tube 32 extends cantilevered through the ventilation opening 26 and is arranged inclined such that it (see FIG. 1) runs below the higher balancer shaft (bearing point 20) and above the lower balancer shaft (bearing point 22) acceptable wall thicknesses between said bearing points 20, 22 and bore 30 for tube 32 are taken into account or provided.
  • the transverse channel 28 is, as indicated schematically in FIG. 1, connected via a tubular branch 34 directly to the pump housing 36 of the water pump (not shown) of the internal combustion engine and supplies cooling water spaces (not shown) arranged on the opposite side of the cylinder housing 10 with cooling liquid , Said pump housing 36 is integrated in the cylinder housing 10.
  • a longitudinal channel 38 is cast into the cylinder housing 10 on one side of the crankshaft axis of rotation, which, as part of the pressure circulation lubrication system of the internal combustion engine, supplies the crankshaft bearings 18 with lubricating oil, among other things, via branch channels 40.
  • transverse channels 28 can also be arranged in further transverse walls 16 of the cylinder housing 10.
  • the transverse channels 28 can also carry other media, in particular lubricating oil from the lubrication system of the internal combustion engine.
  • the cylinder housing 10 can also be provided in a manner not shown with cylinder liners which have the said running surfaces for the pistons 14.

Abstract

L'invention concerne un dispositif permettant de guider des milieux dans le carter de vilebrequin cylindrique d'un moteur à combustion interne à cylindres en ligne, à pistons alternatifs, comportant plusieurs cylindres. Le système de guidage des milieux présente entre autres au moins un canal transversal menant d'un grand côté à l'autre du carter de vilebrequin cylindrique. Une structure avantageuse et simple en termes de conception et de production est obtenue dans la mesure où le canal transversal s'étend dans un espace libre, formé par des cavités de deux pistons adjacents l'un à l'autre, dans la zone inférieure des tiges de pistons et au-dessus du logement de vilebrequin du moteur à combustion interne.
