Definitions
- the present invention relates to an oil pan intended to be fixed under the engine block of an internal combustion engine.
- the main function of an oil sump is to contain the oil needed to lubricate an engine and to dissipate some of the heat generated by the engine.
- an oil pan has a shell which is fixed under the engine block.
- the oil in the crankcase is sucked in by an oil pump and is propelled to the different parts of the engine to be lubricated (for example, camshafts, valve stems, crankshaft bearings, piston / cylinder, piston / connecting rod, crankshaft / connecting rod, etc.), then the oil returns to the sump by natural run-off or ducted return depending on the case.
- an oil pump for example, camshafts, valve stems, crankshaft bearings, piston / cylinder, piston / connecting rod, crankshaft / connecting rod, etc.
- the housing receives in its interior volume a strainer for stopping solids such as filings produced by the engine components contained in the oil before they reach the suction port of the pump, and a so-called plate anti-emulsion, the role of which is to prevent or limit the movements of the oil in the crankcase, in particular to the free surface of the oil.
- the engine components When starting the engine, the engine components are at ambient temperature. During the transitional phase of temperature rise to the optimum operating temperature, the engine does not operate optimally and in particular the fuel consumption is substantially higher; this is due to the fact that the combustion is not done at optimal temperature.
- a search path aims at reducing the duration of the transient start-up phase 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 time for heating the engine lubrication circuit oil and thus to reduce the fuel consumption at engine start-up as well as the carbon dioxide emissions.
- the invention relates to an oil sump comprising a lower shell intended to contain lubricating oil of a engine block, in which a flow of oil, called suction oil flow, is sucked by a suction tube to feed a lubrication circuit and an oil flow, said flow of oil returning, falls into the crankcase oil.
- the oil sump comprises an anti-emulsion plate disposed in the oil sump and orientation means for orienting at least a portion of the oil flow returning to an area at the mouth of the suction tube. during a transitional period during which the oil has a temperature below an optimum operating temperature.

- the oil flow returning to the crankcase is directly sucked by the oil pump without having dissipated the heat which it carries in the oil mass of the crankcase.
- the invention establishes a bypass of the oil flow returning to retain the heat it contains and directly use the flow of oil returning to supply the lubrication circuit.
- the oil flow sucked comes mainly from the oil flow returning from the lubrication circuit. In contact with the engine parts, the flow of oil returning increases in temperature.
- the oil flow sucked during the transitional period contains mostly oil heated by the engine components, which accelerates the rise in temperature of the oil sucked to its optimum operating temperature.
- the re-use in a loop, during the transitional period, of the oil flow returning to the suction oil flow makes it possible to accelerate the rise in temperature of the oil sucked by avoiding a cooling caused by the mixing of the oil. oil flow returning to the oil stored in the lower shell.
- the rapid rise in temperature of the oil sucked up to its optimum temperature makes it possible to reduce the heating time of the engine lubrication circuit.
- the invention provides an oil sump which reduces the oil time of the engine lubrication circuit.
- the engine reaches its optimum operating temperature more quickly and thus lowers excess fuel consumption during the engine start-up phase as well as reducing carbon dioxide emissions.

- An opening 87 is formed in the bottom wall 84a. On either side of the opening 87, the bottom wall 84a is inclined so that the opening 87 is at the low point of the bottom wall 84a.
- the opening 87 is closed by a bimetallic shutter 88 to change it from its passing position to its non-conducting position.
- the bimetal shutter 88 is movable between an open position in which the aperture 87 is passing for oil and a closed position in which the bimetal shutter 88 closes the aperture 87.
- the bimetal shutter 88 is configured to move to the closed position when the oil circulating on the anti-emulsion plate 8 reaches or exceeds an optimum operating temperature of the engine which is usually between 30 ° C and 50 ° C.

- the plate is adapted to be fixed to the housing 45.
- the bimetal shutter 88 when the engine is started, the bimetal shutter 88 is in the open position because the oil has not yet reached its optimum temperature.
- the flow of oil returning II flows mainly through the opening 87.

When the flow of oil returning reaches or exceeds a defined viscosity, the flow of oil returning can through the gate 89 and flow through the through holes 86.
