Definitions

  • the invention relates to a device for increasing the engine oil temperature rise speed.
  • the invention applies to vehicles, in particular motor vehicles.
  • Vehicle fuel consumption is a function in particular friction in the engine and therefore also the engine lubricating oil temperature.
  • consumption and engine wear is high as long as the engine and oil are not reheated to their optimum temperature of operation.
  • this type of device has the disadvantage of being expensive and increase battery consumption.
  • the document FR 2 423 632 teaches a device for adjusting the temperature of the lubricating oil engine with a main oil sump containing a oil collector.
  • the collector which has a volume lower than the main sump, collects the oil that has circulated in the engine.
  • the manifold is connected to the main casing by means of a thermostatic valve.
  • the suction point of the engine oil pump is connected, according to valve position, either with the manifold when the oil temperature is low, either with the oil pan when the operating temperature is reached.
  • An object of the present invention is to provide a device for increasing the rate of climb engine oil temperature comprising a sump containing engine lubrication, an oil collecting tank having circulated in the engine, the tarpaulin having a volume less than sump, an oil pump with a suction point located in the cover, the cover having a single orifice communication of the oil contained in the crankcase with the oil contained in the tarpaulin, means creating a loss load on the crankcase oil circulation circuit to the cover being provided inside and / or outside the tarpaulin, to ensure, during start-ups, a re-aspiration preferential warmer oil from the tarpaulin that has circulated in the engine, while allowing the circulation of oil from casing towards the suction point in the event of a drop in level oil in the tarpaulin and / or temperature homogenization oil in the tarpaulin and in the crankcase.
  • An object of the invention is to overcome all or part of the drawbacks of the prior art noted above.
  • the means creating a loss load comprises at least one deflective wall located near the hole, so as to form a baffle for the oil in its circulation circuit from the housing to the suction point.
  • the cover is located in the casing, the means creating a pressure drop on the circuit oil flow from the crankcase to the tarpaulin 2 are located at level and / or near the orifice.
  • the means creating a loss load on the crankcase oil circulation circuit to the cover has a mesh added to the orifice.
  • the setting hole communication of the oil contained in the sump with the oil contained in the tarpaulin is formed in the wall constituting the tarpaulin bottom.
  • the setting hole communication of the oil contained in the sump with the oil contained in the tarpaulin is formed in one of the walls side of the sheet, that is to say in one of the walls substantially perpendicular to the bottom of the sheet.
  • the means creating a loss load on the crankcase oil circulation circuit to the cover has two deflecting walls located in the tarpaulin, close to the orifice, and substantially perpendicular to the bottom of the sheet, to form a baffle for the oil in its circulation circuit from the crankcase to the suction point.
  • the device for increasing the rate of climb engine oil temperature comprises a sump 1 containing the engine lubricating oil and a cover 2 collector, located in the casing 1 and intended for recover the oil circulating in the engine 4.
  • the oil pan 1 is fixed to the part lower of the cylinder block 11.
  • the collecting cover 2 which has a volume lower than that of the oil pan 1, is immersed in the latter's oil reserve.
  • Tarpaulin 2 collector is fixed on the lower part of the cylinder block 11 by through, for example, a flange 12 which covers the flange 13 for fixing the oil sump 1. In this way, any the oil R which flows from the engine 4 is recovered by the cover 2.
  • the engine lubrication system 4 includes a oil pump 3 with a suction strainer 5 located in the tarpaulin 2.
  • the tarpaulin 2 has an opening 6 for setting communication of the oil contained in the casing 1 with the oil contained in the sheet 2.
  • the orifice 6 of communication crankcase oil 1 with tarpaulin oil 2 is formed in one 10 of the side walls of the sheet 2. That is to say that the orifice 6 is formed in one of the walls substantially perpendicular to the bottom 9 of the cover 2.
  • Means 7, 8A, 8B creating a pressure drop on the circuit B for circulating the oil from the sump 1 to the cover 2 are provided at the opening 6 and inside the tarpaulin 2, to ensure preferential re-aspiration of the oil recovered in tarpaulin 2 during, in particular, starts.
  • These means creating a pressure drop on circuit B of circulation of oil from sump 1 to tarpaulin 2 include two deflector walls 8A, 8B located in the cover 2 and one mesh 7 added to hole 6.
  • the two deflecting walls 8A, 8B are substantially perpendicular to the bottom 9 of the sheet 2 and are located at near orifice 6, so as to form a baffle for the oil in its circuit B for circulating the crankcase 2 towards the point of the oil pump 3.
  • the baffle formed by the two walls 8A, 8B can be "vertical". That is to say, the two walls 8A, 8B are vertically offset so that the oil circulation circuit B from the crankcase 1 passes on the one hand between the lower edge of a first wall 8A and the bottom 9 of tarpaulin 2, and on the other hand above the second 8B wall.
  • the means 7, 8A, 8B introducing a pressure drop on the circuit B for circulating the oil from the crankcase 1 to the tarpaulin 2, however, allows the oil to flow from the sump 1 to the suction point A of the cover 2 in the event of a fall of the oil level in the tank 2 and / or homogenization of the oil temperatures in tarpaulin 2 and in crankcase 1. From this way, any risk of damage to the lubrication of the engine with too hot oil is avoided. Similarly, when the flow rate of the pump 3 increases due to increasing engine speed oil can flow from the crankcase 1 in the cover 2 to be sucked there.
  • Figures 2 and 3 show a second mode of realization of the invention.
  • FIG. 2 only the collecting cover 2 is shown at the base of the engine 4.
  • the cover 2 collects the descents oil C from the cylinder head and the oil descents P from the bearings, the oil collected by the tank 2 is sucked back by the pump 3.
  • Tarpaulin 2 in Figures 2 and 3 differs from that in Figure 1 by the fact that the opening 6 for placing the casing in communication 1 and of the sheet 2 is formed in the wall 9 constituting the bottom of the sheet 2.
  • the sheet 2 of Figures 2 and 3 also differs of that of FIG. 1 by the fact that it does not include any grid attached to port 6.
  • the cover 2 of FIGS. 2 and 3 constitutes a formed reservoir, seen from above, by a substantially rectangular portion which is extended, at one of its sides, by a substantially triangular portion.
  • the suction point A of the pump 3 is located substantially in the center of the portion rectangular while the orifice 6 is located substantially at the end of the triangular part which constitutes the end of the cover 2.
  • the flange 12 for fixing the cover 2 on the part lower of motor 4 forms a rim on the upper edge of the tank constituted by the cover 2.
  • the two deflecting walls 8A, 8B which are perpendicular to the bottom 9 of the sheet 2, are integral respectively of two opposite side walls of the sheet 2.
  • the two deflecting walls 8A, 8B form a "horizontal" baffle. That is to say, when flow from port 6 to suction point A, oil bypasses the free edges of the two walls 8A, 8B which are perpendicular to the bottom 9 of the cover 2.
  • crankcase oil circulation circuit 1 to tarpaulin 2 which have been described above can be replaced by any other equivalent means.
  • these means creating a pressure drop for the oil can be arranged outside and / or inside the cover 2 and / or at level of the orifice 6 of communication.
