Definitions

  • the invention relates to an outlet channel for the cylinder of an internal combustion engine with a lower channel part which can be sealed off from the upper end of the cylinder by means of a valve whose valve tappet extends through the outlet channel, the valve tappet being surrounded by a circular wall in the region of the penetration point is, which extends at right angles to the valve lifter, from which the bead formed as a flow divider with a convex cross section extends in the direction of the outlet opening of the outlet channel and gradually decreases.
  • the object of the invention is to design the flow channel in such a way that the flow losses, in particular in the region of the valve tappet, can be kept small.
  • a second convex flow divider extends from the wall in the direction of the inlet opening of the outlet duct, the cross section of which gradually decreases in the direction of the inlet opening, the wall opposite the flow dividers being continuously concave in cross section. Due to the advantageous design and arrangement of the outlet channel in connection with the two flow dividers extending into the outlet channel, proper flow guidance of the fluid is ensured, so that the losses due to the division of the two gas streams through the valve and the flow dividers can be kept very small.
  • the two flow dividers are divided by a triangular incision, which is formed by a wall running perpendicular to the axis of the valve lifter and an adjoining wall running parallel to the longitudinal axis of the valve lifter, and each The center line of the two convex flow dividers runs approximately on a circular arc, both circular arcs also being connected by a circular arc.
  • 10 denotes an exhaust port of an internal combustion engine, not shown in the drawing, which has a lower channel part 12 which is connected to the upper end of a cylinder 14 of the internal combustion engine and which serves to receive a valve seat 16.
  • the outlet channel 10 also has an upper channel part or outlet part 18 which, as can be seen in FIG. 8, has a circular cross section.
  • the valve plate 22 seals the lower passage cross section of the channel part 12 in the position according to FIG. 1.
  • the lower channel part 12 and the upper channel part 18 are connected to one another via an intermediate channel part 28.
  • the intermediate channel part 28 consists of an upper channel wall 30 and a lower channel wall 32.
  • the assignment and design of the opposite channel walls 30 and 32 is shown in the individual cross-sectional views in FIGS. 2 to 8.
  • the lower channel wall 32 is concave in cross section over the entire length.
  • the valve tappet 24 extends through the upper channel wall 30 and is surrounded in the area of the penetration point by a bead or an end face 34 which extends approximately at right angles to the axis of the valve tappet 24.
  • the upper channel wall 30 is convex, so that a nose-shaped part 30 extends into the outlet channel 10.
  • a vertical wall 38, which extends parallel to the axis of the valve tappet 24, is formed by the bore extending through the nose-shaped part 36 or the bead 34 for receiving the valve tappet 24.
  • the upper channel wall 30, the highest elevation of the nose-shaped part 36 is located in the region of the valve tappet 24 and thus of the bead 34.
  • the cross section of the nose-shaped part 36 gradually decreases in the direction of the lower channel part 12 and thus forms a flow divider for the fluid entering the outlet channel.
  • the upstream and downstream flow dividers or nose-shaped parts 36 and 40 serve to divide the fluid in the area of the valve tappet 24 in order to reduce the turbulence within the outlet channel 10 and to ensure an almost laminar flow of the flow.
  • the nose-shaped parts or flow dividers 36 and 40 also cause a reduction in the cross section of the outlet channel 10 in the region of the bead 34 and the valve tappet 24. This also reduces flow losses.
  • the special shape of the outlet channel 10 serves to improve the fluid flow.
  • the outlet duct 10 can either be provided in the cast part of the cylinder head or cylinder block or in an insert part which is made, for example, of non-metal or ceramic.
