Definitions

  • the invention relates to an internal combustion engine, in particular of a motor vehicle, with an oil pan for receiving lubricating oil of a pressure circulation lubrication, wherein the Oil pan is at least partially double-walled and in the oil pan a Oil pump is provided with a suction port, and with a thermostatic valve, which, depending on a lubricating oil temperature optionally at elevated Cooling the suction with the double-walled area of the oil pan so connects that lubricating oil at least partially through the double-walled area the oil pan circulates, and with low cooling demand, the suction of the double-walled area such that the lubricating oil in the double-walled area the oil pan substantially from the circulation generated by the oil pump is separated, according to the preamble of claim 1.
  • Oil pans of internal combustion engines have in addition to their task as oil sump for the circulating engine oil also has a heat exchanger function to the primarily in the engine oil flowing frictional heat to the umstMailde air dissipate.
  • An increased heat dissipation is in particular by those with ribs profiled aluminum oil pan achieved.
  • US-A-4,296,716 discloses an internal combustion engine whose sump is so in two Chambers is divided, that the outer second chamber the bottom of the inside lying first chamber forms. Both chambers communicate via openings each other and each have a suction port, which via a thermostatic valve with the oil pump communicate. At low oil temperature, the oil becomes major conveyed from the inside first chamber, and at oil temperatures over a certain predefined limit, the oil is predominantly from the outside promoted second chamber.
  • the thermostatic valve is here by two suction lines connected to the two suction ports and located in the inside Chamber of the oil pan.
  • thermostatic valve suction lines and suction ports decreases inside the sump very much space to use, which is one in general desired compact design of the oil pan counter.
  • quite complex attachment of the intake and Saug effetive cost factor.
  • the present invention is therefore based on the object, an internal combustion engine the o.g. Art to provide, which the above-mentioned disadvantages by a inexpensive and compact arrangement of the oil supply to the pump eliminated.
  • thermostatic valve For temperature-dependent actuation of the thermostatic valve has this for example, an expansion element.
  • thermostatic valve for actuating the thermostatic valve is a spring, in particular Coil spring, provided, which the thermostatic valve in the direction of the wall Pressurized oil pan.
  • An oil flow control in the double-walled area of the oil pan is achieved by that an inner wall of the double-walled area of the oil pan punctiform or is linearly connected to an outer wall of the oil pan.
  • thermostatic valve To support a circulation in the double-walled area of the sump with lower 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 sump in the region of Thermostatic valve increased.
  • the thermostatic valve is designed as a cylinder valve.
  • an inner wall of the double-walled region of the oil sump is preferably made of plastic or metal, in particular sheet metal, or a casting material.
  • Oil drain plug provided which by an inner wall and an outer wall of the double-walled region of the oil pan extends so that it passes through the Inner wall seals.
  • an otherwise not shown internal combustion engine comprises an inner panel 12 such that the oil pan 10 is double-walled.
  • the Inner panel 12 is provided with a plurality of openings 14 which pass through an oil enable. Further, the inner panel 12 is multi-point or line with the Oil pan 10 connected, for example, medium 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, in which case the oil in the oil circulation of an interior 26 passes through an annular suction port 28 to the oil pump 18.
  • a thermostatic regulated cylinder valve 20th acts between the oil pan 10 and the inner panel 12 located, resting lubricating oil as a heat insulating layer and prevents unwanted heat dissipation to the environment of the oil pan 10.
  • the suction of the oil pump 18 therefore leads to an oil flow from the interior 26 via the plurality of openings 14, over the gap 34 and via the ring opening 32 to the oil pump 18, wherein a circulation of the Lubricating oils over the gap 34 with a correspondingly high heat dissipation via an outer surface of the oil pan 10 results, with the flowing over the gap 34 Lubricating oil is in heat-conducting contact.
  • the gap 34 near the cylinder valve 20 has an increased wall distance of the Inner sheet 12 from the outside of the oil pan 10 on.
  • An oil drain plug 36 screwed to the oil pan 10 is such in length formed so that it with its end an opening 38 in the inner panel 12 substantially sealing closes.
  • the oil pan 10 itself is preferably made of metal, in particular made of aluminum.
  • the Inner panel 12 may alternatively be made of a plastic.
