Definitions

  • the present invention relates to an engine comprising a cylinder block.
  • the invention also relates to a vehicle, in particular a motor vehicle, comprising such an engine.
  • a heat engine usually comprises a cylinder block closed by a cylinder head.
  • the engine comprises a cooling circuit in which a heat transfer fluid is circulated by means of a pump and which, in turn, is cooled by passing through a radiator.
  • a pump conventionally comprises a volute, one outlet of which is connected by a conduit to an internal circuit of the cylinder block comprising cooling chambers allowing circulation of this fluid around the cylinders of the engine.
  • a general problem of such an engine is linked to the fact that the pump and part of the cooling circuit, the duct of which connecting the outlet of the volute to the internal circuit of the cylinder block, are conventionally arranged at the level of an external face of the engine and then has a size which is not suitable for the dimensions of the engine compartment of today's vehicles.
  • the present invention aims to overcome these drawbacks associated with the state of the art.
  • the invention relates to a motor according to claim 1.
  • the invention also relates to a vehicle, in particular a motor vehicle comprising such an engine.
  • a cylinder block 8 may, for reasons of lightening, be made of aluminum and for economic reasons and in large series may be made in a foundry of the high-pressure casting type.
  • this cylinder block 8 comprises an internal circuit 7 for the circulation of a heat transfer fluid otherwise called "cooling liquid" which is intended for example to cool the engine by allowing circulation of this fluid around the cylinders of the engine.
  • the internal circuit 7 comprises an internal supply conduit 15 formed by at least one cooling chamber, one inlet 6 of which comprising an inlet orifice, opens into a mounting cavity 14 of this cylinder block 8.
  • This mounting cavity 14 also includes an outlet 4 provided with an orifice of a volute 3 of a heat transfer fluid pump 2 for circulating this pressurized fluid in a cooling circuit of this engine.
  • This outlet 4 is an orifice 4 communicating with the cavity of the volute 3 of the pump 2.
  • a pump 2 is preferably arranged in a housing defined in the engine and in particular in a housing defined in the cylinder block 8 and this , so as to reduce the size of the motor.
  • the volute 3, also called the “high-pressure chamber” of the pump 2 is intended to receive a blade 17, or a turbine, contributing to the circulation of the pressurized fluid in the cooling circuit.
  • This vane 17 is mounted on one end 16 of a pump shaft passing through a pump body (not shown) on either side.
  • This volute 3 is formed in the cylinder block 8 and it comprises in a intermediate part, arranged for example substantially in line with the axis of the pump, a supply inlet (not shown) provided with an orifice intended to allow the pump 2 of the engine to be supplied with heat transfer fluid.
  • this cylinder block 8 also comprises an external duct 1 from the outlet 4 of the volute 3 of the pump 2 which is fixed to the external face 9 of this casing 8.
  • This external duct 1 can be a removable part which is attached to the outer face 9.
  • the outer conduit 1 comprises first and second components 5a, 5b which can be two separate parts which are assembled/connected to each other in a sealed manner. Alternatively, these first and second components 5a, 5b can together form a single piece.
  • This external duct 1 is arranged in the mounting cavity 14 while being mechanically and sealingly linked to the external face 9 of the cylinder block 8.
  • This mechanical connection is made from cooperation between fixing elements, in particular elements of screwing, with a connection zone 10.
  • This connection zone 10 is preferably defined at the level of a peripheral edge of this assembly cavity 14.
  • the first component 5a is capable of guiding the heat transfer fluid via a second channel 11b from the outlet 4 of the volute towards the inlet 6 of the internal circuit 7 for circulation of the heat transfer fluid defined in the cylinder block 8.
  • the first component 5a is capable of participating in guiding the heat transfer fluid from the outlet 4 of the volute towards the inlet 6 of the internal circuit 7.
  • This first component 5a of this external conduit 1 forms with the second component 5b a first channel 11a for circulation of the heat transfer fluid to at least one device of the cooling circuit.
  • a device is another consumer heat transfer fluid of the cooling circuit which can be, for example, a heat exchanger such as a heater or even an engine oil exchanger better known by the acronym "EMO" to evacuate the heat produced in the engine oil sump level.
  • the first channel 11a comprises an outlet 19 provided with an orifice.
  • This outlet 19 is included in a connecting part 18 of the second component 5b which has a generally cylindrical shape and on which part 18 one end of a connecting conduit, also called hoses, can be fixed in order to connect the external conduit 1 to the cooling circuit device.
  • a connecting conduit also called hoses
  • the internal circuit 7 can comprise a control element (not shown) for the circulation of the pressurized heat transfer fluid.
  • This control element placed downstream of the inlet 6, makes it possible to manage the flow at the level of the cooling chambers of the internal circuit 7.
  • This control element can be a solenoid valve, a controlled valve or even a thermostatic valve.
  • the external duct 1 is then adapted to a variable circulation of the heat transfer fluid for cooling the cylinder block 8. Indeed, when the control element is in a closed position of the internal circuit 7, the flow rate of the fluid passing through the second channel 11b described below and which continues to supply the outlet 19 so as not to interrupt the supply of fluid to the other consumers.
  • the first component 5a of this external conduit 1 is capable of guiding the heat transfer fluid from the outlet 4 of the volute 3 of the pump 2 towards the inlet 6 of the internal circuit 7 comprising the internal supply conduit 15 formed of at least a cooling chamber. More precisely, the first component 5a forms with the external face 9 of the casing 8 and in particular with the assembly cavity 14, the second channel 11b for the circulation of the heat transfer fluid towards this inlet 6 of the internal circuit 7.
  • the first component 5a of this external duct 1 comprises a passage zone 12 for the heat transfer fluid from the second channel 11b to the first channel 11a.
  • This passage zone 12 is preferably included on a part of this first component 5a which can be defined equidistant from the ends 24a, 24b of this component 5a visible on the figure 2 .
  • This passage zone 12 is ensured by openings 13 visible in a cross section of the passage zone 12 on the picture 3 which is essentially an inverted "U" shape.
  • the passage zone 12 comprises side walls 23 which each comprise an opening 13. These openings 13 participate in the passage of the heat transfer fluid from the second channel 11b to the first channel 11a.
  • this cylinder block 8 when the pump 2 performs a circulation of the coolant in the cooling circuit, the fluid is then evacuated from the pump 2 via the outlet 4 of the volute 3 to circulate under pressure in the second channel 11b in the direction of the arrows referenced 20. By thus circulating in this second channel 11b, this fluid is then led both to the internal circuit 7 defined in the cylinder block 8 via the inlet 6, and to at least one device of the cooling circuit by crossing the passage zone 12 in particular the openings 13 defined in this zone 12 in accordance with the direction of the arrows referenced 21.
