Definitions

  • the invention relates to a fuel guide in the cylinder housing of an internal combustion engine and a method for producing this fuel guide according to the features specified in the preamble of claims 1 and 9.
  • the object of the invention is to achieve a space-saving and at the same time weight-reducing fuel guide on the cylinder housing of an internal combustion engine by simple measures and to enable this fuel guide to be produced easily and with little effort.
  • the longitudinal channel Due to the special arrangement of the longitudinal channel, no additional space-consuming solid ribs or castings are necessary, and due to the special fuel connection between the receiving bore and the longitudinal channel, none are otherwise customary Ball locks are required in the cross holes passing through the receptacle. Furthermore, the longitudinal channel running away from the plug-in pumps, from which fuel branches off from the plug-in pumps via the oblique bores, does not result in an increase in temperature in the fuel.
  • this connecting web can be narrow and thus also designed to save weight.
  • the through channel that crosses the mount in the middle enables a diagonal arrangement of the screw fastening provided for the plug-in pump on the pump support. This means that there is no disadvantageous one-sided pump mounting.
  • the positioning of the longitudinal channel in a material-reinforcing area is particularly advantageous, in which boundary walls of neighboring rooms converge and virtually form a node.
  • the measure according to claim 3 leads to an unobstructed drilling of the oblique hole.
  • Another step is the deep hole drilling of the through-channel, which crosses the still existing solid part. Then the large-diameter mounting hole for the plug-in pump is drilled.
  • the trough-like depression with a deepest point in the middle of the receptacle serves as a drilling aid or centering the receptacle bore.
  • Another advantageous measure according to claim 12 leads to a significant reduction in material removal when drilling the large receiving bore.
  • upstanding receptacles 5 are formed, the receiving bores 6 of which are provided for plug-in pumps 7 (FIG. 2).
  • Narrow connecting webs 8 projecting from the long side of the row of cylinders are arranged between the respective receptacles 5, in which the through channel 3 intersecting the longitudinal axis of each receptacle 5 runs.
  • the longitudinal channel 2 is located in an area in which boundary walls 9, 10, 11 from neighboring rooms 12, 13, 14 run towards one another, is located approximately at the level of the through-channel 3 and runs in the cylinder housing 1 next to the plug-in pumps 7.
  • the oblique bore 4 leads away from the receiving bore 6 and opens into the longitudinal channel 2.
  • the extension of this oblique bore 4 lies within the upper opening 17 of the receiving bore 6.
  • FIG. 2 shows an embodiment with a plug-in pump 7 installed and the fuel flow profile indicated by arrows.
  • the plug-in pump 7 has superimposed annular grooves 18, 19, of which the upper fuel ring groove 18 is connected to the oblique bore 16 and the lower fuel ring groove 19 is connected to the through-channel 3.
  • FIG. 3 shows the fuel feed leading to the plug-in pumps 7 and FIG. 4 shows the fuel return leading away from the plug-in pumps 7. 3, 4, the connecting webs 8 can be seen in plan view, in which the through-channels 3 run.
  • the fuel guide described above is implemented in the same way in a cylinder housing 1 shown in plan view with cylinder rows 21, 22 arranged in a V-shape (FIG. 5).
  • connection provided in the longitudinal center of the longitudinal channel 2 and designated 25.26 is for a fuel supply line (not shown) and a connection designated 27.28 for a fuel return line (not shown).
  • the connections 27, 28 lie on one longitudinal half of the internal combustion engine between the upstanding receptacles 5. However, the connections 27 ', 28' can also be arranged behind the last receptacle 5 and the end face of the internal combustion engine, as can the connections 25 ', 26'.
  • the respective longitudinal and through-channel of both cylinder rows can at least one end without a ball lock and are connected to one another by transverse bores 30, 31 in at least one end cover 29 attached to the end of the cylinder housing 2 (shown in dash-dot lines).
  • the line arrangement in at least one end cover can be such that the connections for the fuel supply line and fuel return line are provided there (indicated by arrows x, y). Instead of the end cover 29, exposed connecting lines can also be provided (not shown).
  • the fuel connection between the two rows of cylinders can also be formed by rectilinear transverse bores 30 ', 31' within the cylinder housing 1, specifically in the end region of the cylinder housing, or there by V-shaped bores 32, 33 which converge in the vicinity of a bearing frame wall 34 (Fig.6).
  • transverse bores 30 ', 31' or the V-shaped bores 32, 33 can, however, also be provided in the case of different cylinder distances between cylinder groups of each row of cylinders (not shown).
  • Each pump support has fastening holes 35, 36 which are diametrically opposite with respect to the receiving bore 6 and are arranged diagonally to the through-channel 3.
  • each receptacle 5 shows the cylinder housing 1 for an internal combustion engine with rows of cylinders arranged in a V-shape in the raw contour cast, in which the elongated upstanding and partially laterally projecting receptacles 5 are partially designed as a solid part.
  • the upper contour or recess 37 of each receptacle 5 is pulled down like a trough and has a deepest point 37a in the longitudinal axis of FIG Recording 5 on.
  • the lower contour or depression 38 of each receptacle 5 is drawn up like a blind hole so that the solid part cast like a web results between the two depressions 37, 38.
  • the raw contour cast is formed on the long sides into narrow connecting webs 8, which are connected to adjacent receptacles 5.
  • the connecting webs 8 lying between the receptacles 5 merely form a projection on the long side of the cylinder housing 1 (FIG. 1).
  • the connecting webs 8 according to FIG. 7 can merge into an upper coolant channel wall 39 which extends between the rows of cylinders and extends along the rows of cylinders.
  • a through passage 3 crossing all the receptacles 5 and running in the connecting webs can be drilled starting from both end faces of the cylinder housing 1.
  • the through-channel 3 intersects the longitudinal axis of each receptacle 5.
  • the longitudinal channel 2 can be drilled in the same way, advantageously simultaneously with the through-channel 3.
