Definitions

  • the invention relates to a method for regulating the cooling of lubricating oil in a Oil pan of a drive machine with pressure lubrication, in particular Internal combustion engine, wherein the oil is collected in an oil pan, which at least is partially double-walled, according to the preamble of claim 1.
  • Die further relates to an internal combustion engine, in particular a motor vehicle an oil pan for receiving lubricating oil of a pressure lubrication system, the Oil pan is at least partially double-walled and one in the oil pan Oil pump is provided with a suction opening, according to the preamble of claim 5.
  • Oil sumps of internal combustion engines have, in addition to their role as oil sumps for
  • the engine oil in the circuit also has a heat exchanger function, primarily to to dissipate frictional heat flowing into the engine oil to the air roaming around it.
  • a increased heat dissipation is achieved in particular by the aluminum oil pan profiled with ribs. This is desired at higher ambient temperatures and high engine speeds.
  • heat dissipation to limit the oil temperature has the winter driving conditions Disadvantage that the warm-up mode by undesirable heat losses Operating temperature level of the engine oil is difficult or not reached. As a result of which there are increased friction losses and increased fuel consumption, what again deteriorated oil quality due to fuel and condensation dilution conditionally.
  • the present invention is therefore based on the object of a method of Above type and an internal combustion engine of the above.
  • kind of providing which eliminate the disadvantages mentioned above and a more controllable heat dissipation of the lubricating oil through the oil pan.
  • an intake opening is a Oil pump with increased cooling requirement at least partially with the double-walled area the oil pan and with a low cooling requirement connected to an interior of the oil pan.
  • the lubricating oil is passed through when there is an increased cooling requirement Openings in an inner wall of the double-walled area of the oil pan directed.
  • a thermostatic valve which is dependent on a lubricating oil temperature optionally with increased cooling requirements, the suction opening with the double-walled area of the Oil pan connects such that the lubricating oil at least partially through the double-walled area of the oil pan circulates, and with low cooling requirements Separates suction opening from the double-walled area so that the lubricating oil in the double-walled area of the oil pan essentially from that generated by the oil pump Circulation is disconnected.
  • the thermostatic valve is on a bottom of the oil pan opposite the Suction opening of the oil pump arranged.
  • a spring is expediently used to actuate the thermostatic valve, in particular Coil spring, provided which the thermostatic valve in the direction of the wall Power applied to the oil pan.
  • An oil flow control in the double-walled area of the oil pan can be achieved in that an inner wall of the double-walled area of the oil pan point-like or line-shaped is connected to an outer wall of the oil pan.
  • thermostatic valve To support circulation in the double-walled area of the oil pan with lower ones Flow rates through the thermostatic valve is a distance between an inner wall and an outer wall of the double-walled area of the oil pan in the area of Thermostatic valves increased.
  • the thermostatic valve is expediently designed as a cylinder valve.
  • an inner wall of the double-walled region of the oil pan made of plastic is preferred or metal, in particular sheet metal, or a cast material.
  • Oil drain plug provided, which is through an inner wall and an outer wall of the double-walled area of the oil pan extends such that it passes through the Seals inside wall.
  • the preferred embodiment of an embodiment of the invention shown in the single figure trained oil pan 10 of an internal combustion engine not otherwise shown comprises an inner plate 12 such that the oil pan 10 is double-walled.
  • the Inner sheet 12 is equipped with a plurality of openings 14 which allow oil to pass through enable.
  • the inner sheet 12 is multiple punctiform or linear with the Oil pan 10 connected, for example by means of welding points or lines 16.
  • thermostatic Regulated cylinder valve 20 is arranged, which by a spring 22 against a bottom 24th the oil pan 10 is pressed, then the lubricating oil in the oil circuit from an interior 26 reaches the oil pump 18 via an annular suction opening 28.
  • the located between the oil pan 10 and the inner panel 12 acts resting lubricating oil as a heat insulating layer and prevents undesired heat dissipation to the surroundings of the oil pan 10.
  • an expansion element 30 presses the Cylinder valve 20 against the spring 22 in the direction of the oil pump 18, so that the original annular suction opening 28 partially or completely closed and instead one Ring opening 32 is effective so that lubricating oil from a space 34 between Oil pan 10 and inner wall 12 is sucked. This is in the right half of the figure of the cylinder valve 20 illustrated.
  • the suction effect of the oil pump 18 therefore leads to an oil flow from the interior 26 through the plurality of openings 14, through the gap 34 and via the ring opening 32 to the oil pump 18, with a circulation of the Lubricating oil via the intermediate space 34 with a correspondingly high heat dissipation gives an outer surface of the oil pan 10 with which the flowing over the space 34 Lubricating oil is in heat-conducting contact.
  • the intermediate space 34 near the cylinder valve 20 has an increased wall distance from the Inner sheet 12 from the outside of the oil pan 10.
  • An oil drain plug 36 screwed to the oil pan 10 is of such length formed that they have an opening 38 in the inner plate 12 with its end substantially seals tightly. Through additional bulkheads 40 with openings 42 acceleration-related oil level changes limited.
  • the oil pan 10 itself is preferably made of metal, in particular aluminum.
  • the Inner sheet 12 can alternatively also be made from a plastic.
