Definitions

  • the present invention relates to an oil sump intended to be fixed under the engine block of an internal combustion engine.
  • the main function of an oil pan is to contain the oil needed to lubricate an engine and to dissipate some of the heat generated by the engine.
  • an oil sump comprises a shell which is fixed under the engine block.
  • the oil present in the crankcase is sucked up by an oil pump and is propelled towards the various engine parts to be lubricated (for example, the camshafts, the valve stems, the crankshaft bearings, the piston/cylinder, piston/connecting rod, crankshaft/connecting rod, etc. interfaces), then the oil returns to the crankcase by natural runoff or by channeled return depending on the case.
  • an oil pump for example, the camshafts, the valve stems, the crankshaft bearings, the piston/cylinder, piston/connecting rod, crankshaft/connecting rod, etc. interfaces
  • the casing receives in its interior volume a strainer making it possible to stop the solid matter such as filings produced by the components of the engine contained in the oil before they reach the suction port of the pump, and a so-called plate anti-emulsion, whose role is to prevent or limit the movement of the oil in the crankcase, in particular on the free surface of the oil.
  • the oil is heated by the engine parts and is cooled in the oil sump, when it mixes with the oil present in said sump.
  • the engine components When starting the engine, the engine components are at ambient temperature. During the transitional phase of temperature rise towards the optimum operating temperature, the engine does not operate optimally and in particular the fuel consumption turns out to be significantly higher; this is due to the fact that the combustion does not take place at the optimum temperature.
  • a research path aims to reduce the duration of the transitional phase of starting so that the engine reaches its optimum operating temperature as quickly as possible.
  • the object of the present invention is to provide an oil sump which makes it possible to reduce the heating time of the oil of the lubrication circuit of the engine and therefore to reduce the fuel consumption when starting the engine as well as the carbon dioxide emissions.
  • the invention relates to an oil sump comprising a lower shell intended to contain the lubricating oil of an engine block, in which an oil flow, called aspirated oil flow, is sucked via a suction tube to supply a lubrication circuit and an oil flow, called the returning oil flow, which falls into the oil sump.
  • the oil pan includes an anti-emulsion plate disposed in the oil pan and orientation means making it possible to direct at least part of the flow of oil returning towards a zone located at the mouth of the suction tube during a transient period during which the oil has a temperature lower than an optimum temperature of functioning.
  • the oil pan further includes a heater adapted to supply thermal energy to said at least a portion of the returning oil flow, said heater including at least one positive temperature coefficient heater.
  • the invention provides an oil sump which makes it possible to cause the flow of oil returning to the sump (that is to say an oil flow which, in contact with the engine components that it has lubricated, is at a temperature which is higher than the temperature of the oil stored in the crankcase which is for its part at a temperature substantially equal to the ambient temperature) a short path by bringing the flow of oil returning directly to the mouth of the oil pump suction tube.
  • the flow of oil returning to the sump is directly sucked up by the oil pump without having dissipated the heat which it carries in the mass of oil in the sump.
  • the invention establishes a bypass of the returning oil flow to conserve the heat it contains and to directly use the returning oil flow to supply the lubrication circuit.
  • the flow of oil drawn in mainly comes from the flow of oil returning from the lubrication circuit. Upon contact with engine parts, the returning oil flow rises in temperature.
  • the flow of oil sucked in during the transient period mainly contains oil heated by the engine components, which accelerates the rise in temperature of the oil sucked in to its optimum operating temperature.
  • the reuse in a closed loop, during the transient period, of the oil flow returning to the sucked oil flow makes it possible to accelerate the rise in temperature of the sucked oil by avoiding cooling caused by the mixing of the oil flow returning to the oil stored in the lower hull.
  • the invention provides an oil sump which makes it possible to reduce the heating time of the oil of the engine lubrication circuit.
  • the engine reaches its optimum operating temperature more quickly and therefore reduces the excess fuel consumption during the engine start-up phase as well as reducing carbon dioxide emissions.
  • the invention also makes it possible to increase the temperature of the returning oil flow by means of a heating device integrated in the oil sump.
  • the heater is configured to heat the returning oil stream before it is reinjected into the engine.
  • the oil sump thus configured will further reduce the time of heats the oil in the engine's lubrication circuit and therefore reduces fuel consumption when starting the engine as well as carbon dioxide emissions.
  • a heating device comprising a heating element with a positive temperature coefficient will also make it possible to prevent the oil in the lubrication circuit from exceeding the optimum operating temperature of the engine.
  • the heating element with a positive temperature coefficient having a threshold temperature beyond which its resistance increases exponentially it will then be possible to choose a heating element with a positive temperature coefficient whose threshold temperature is substantially equal to optimum engine operating temperature.
  • the resistance of the heating element will increase in such a way that it will greatly reduce, or even completely cancel the thermal energy supplied by the heating element, thereby stopping the increase in oil temperature.
  • Self-regulation of the temperature of the oil flow returning will therefore be easily obtained by means of this heating element with a positive temperature coefficient, without the need to use temperature sensors to control the temperature of the oil returning from the engine in the oil pan.
  • the invention relates to an oil sump 1 intended to be fixed to an engine block.
  • the oil sump 1 comprises in particular a lower shell 2, a suction tube 44 connected at one of its ends to an oil pump and which opens at its second end into the lower shell 2, an anti-emulsion plate 8 fixed on the lower shell 2 and orientation means which allow to direct a flow of oil returning.

  • the active orientation means allowing the orientation of the returning oil flow II consist of a bimetallic shutter 88 arranged at the level of the opening 87.
  • these active orientation means may be supplemented or replaced by bimetallic shutters arranged at the level of the other outlet orifices (mentioned above) of the anti-emulsion plate 8.
