Definitions

  • the invention relates to an oil pan for an internal combustion engine.
  • an oil pan for an internal combustion engine which has a bottom part for the oil sump and a suction pipe, which opens into a suction region of the bottom part.
  • the suction region has a cylindrical wall section, in which one or more suction windows are arranged and which is closed at the top with a lid.
  • An oil pump provides at the intake, in which the suction pipe opens, for a negative pressure, whereby the oil located in the bottom part first flows through the suction window in the suction and then from the suction into the suction pipe.
  • a disadvantage of this embodiment is the complex structural design of the intake, which leads to a high manufacturing costs and on the other hand, the installation and maintenance difficult.
  • the oil pan according to the invention for an internal combustion engine has a bottom part for forming an oil sump and a suction channel for sucking oil.
  • the suction channel is arranged such that it opens into the oil sump via an orifice.
  • the suction channel has a nose for at least partially covering the suction channel cross section in the horizontal flow direction.
  • the arrangement of a preferably cap-shaped nose on the suction channel in the region of the mouth is by a simple structural design of the suction channel, without additional elements must be arranged in the oil pan, a uniform flow of the oil sump into the suction channel for the oil to be sucked achieved, which is prevented by the nose that air can enter the suction channel.
  • the nose it is achieved that the oil can preferably flow into the suction channel only at the lowest oil level in the oil sump.
  • the nose extends over at least a portion of the Saugkanalqueriteses in the flow direction, so that between the bottom part and the nose preferably a gap is formed, through which the oil can flow from the oil sump into the suction channel.
  • the suction channel is closed in the mouth region through the nose up and only a narrow gap is formed in the mouth region of the suction channel, a disadvantageous vortex effect of the incoming oil is prevented.
  • the distance between the lower region of the nose and the portion of the suction channel opposite the lower region of the nose preferably corresponds to the cross-sectional area of the suction channel.
  • the inventive arrangement of a nose for at least partially covering the Saugkanalqueriteses in the horizontal flow direction in the mouth in the suction channel is in particular causes no air due to the negative pressure in the mouth area is sucked during the promotion of the oil, which is disadvantageous for the engine lubrication would affect.
  • the oil level in the oil pan is prevented by the nose that in the mouth region of the suction channel, the oil level can drop so much that air could get into the suction channel.
  • the nose achieves a simple structural design with only a low manufacturing cost of the oil sump.
  • the assembly cost is reduced.
  • fewer parts are required in the oil pan according to the invention, since, for example, no additional device for suction in the region of the oil sump is required.
  • no additional cover is required by the arrangement of a nose at the mouth of the suction channel. The fact that now fewer parts are needed, the other parts in the oil pan, in particular in the area of the oil sump, parts have greater tolerances.
  • the preparation can be done easily and quickly, for example, by a side opening is milled into a sealed with a cross-sectional area of the tube.
  • the nose is preferably conical.
  • the nose extends geodetically from top to bottom. This creates a gap in the region of the mouth between the bottom part and the nose, which the oil has to pass before the oil can flow into the suction channel, preventing air from getting into the suction channel together with the oil.
  • the nose is integrally connected to the suction channel. Due to the one-piece connection of the suction tube with the nose, a simple production is possible and possible leakage between the transition region of the suction tube to the nose are prevented.
  • the suction channel is at least partially connected in one piece with the bottom part.
  • the suction channel is preferably connected in one piece to the bottom part in the area opposite the nose.
  • the bottom part at least partially forms the mouth.
  • the area of the suction channel, on which the nose is arranged projects beyond a part of the bottom part, so that the mouth area on the nose opposite side of the suction channel is at least partially formed by the bottom part.
  • the bottom part is flat in the region of the mouth. Due to the planar design of the bottom part, the distance of the nose to the bottom part is preferably uniform, so that the oil flow can be sucked evenly into the suction channel, whereby the oil flow in turn can flow with a constant pressure over the cross-sectional area of the suction channel into the suction channel. Due to the uniform inflow, an adverse vortex flow of the oil flow is avoided.
  • the invention further relates to an internal combustion engine having a crankshaft housing and an oil pan connected to the crankshaft housing, wherein the oil pan can be trained and developed as described above.
  • oil pan 10 for an internal combustion engine has a bottom part 12 for forming an oil sump and a suction channel 14 for the suction of oil, wherein the suction channel 14 opens via an orifice 16 into the oil sump.
  • the oil sump of the bottom part 12 of the oil pan 10 is the oil, which is provided for the engine lubrication.
  • the oil sump is here preferably formed perpendicular to the bottom of the bottom part 12.
  • the suction channel 14 is preferably cone-shaped, wherein the diameter of the suction channel 14 at the mouth 16 has a smaller diameter than at the mouth 16 opposite side, on which a filter unit 18 is arranged.
  • the filter unit 18 can for example consist of a coarse filter which sieves predominantly larger particles from the oil flow to be conveyed. A further fine filtering can take place in a second filter (not shown here), the filter elements of which may preferably consist of paper or fibrous material fillings.
  • a sealing element 20 for example a plug, is provided in order to seal the suction channel 14 at the opposite side of the mouth 16.
  • the suction channel 14 preferably has the shape of a straight elongated tube, wherein advantageously in the suction channel 14 no flow-deflecting elements are provided.
  • the suction channel 14 in the region of the mouth 16 a nose 22 for at least partially covering the Saugkanalquerroughes in the horizontal flow direction.
  • the nose 22 extends over at least part of the cross-sectional area of the suction channel 14, the nose 22 preferably being arranged on the side of the suction channel 14 opposite the bottom part 12. Between the bottom part 12 and the nose 22, a gap is formed, through which the oil from the oil sump can flow in the flow direction in the suction channel 14.
  • the nose 22 In the region of the mouth 16 of the suction channel 14 at the point at which the nose 22 is arranged, preferably designed to be longer than the nose 22 opposite region of the suction channel 14, which is adjacent to the bottom part 12, so that the part of the suction channel 14 with the nose 22 may overlap a portion of the bottom portion 12.
  • the bottom part 12 may in this case at least partially the mouth 16 form and is preferably formed flat in the mouth 16.
  • the nose 22 extends geodetically from top to bottom in the direction of the bottom part 12, wherein the nose 22 is formed substantially perpendicular to the bottom part 12.
  • a gap is formed, through which a defined amount of oil flow from the oil sump can flow in the direction of the suction channel 14, being prevented by means of the nose 22 in a simple manner that air together with the oil in can flow the suction channel 14.
