Definitions

  • the present invention relates to the field of cooling circuits for internal combustion engines, in particular for motor vehicles.
  • a motor vehicle comprising an internal combustion engine is equipped with a cooling circuit intended to regulate the temperature of the engine.
  • the temperature is lowered by the passage of a cooling liquid whose circulation is generated by a pump.
  • the liquid is conventionally called water but most of the time corresponds to a glycol water type coolant.
  • exhaust gas recirculation conduit also known by the Anglo-Saxon name “Exhaust Gas Recirculation” or by the abbreviation “EGR”.
  • EGR Exhaust Gas Recirculation
  • the function of such a conduit is to take exhaust gases at the outlet of the internal combustion engine to reinject them into an intake conduit of the engine. In this way, the recirculation duct makes it possible to limit fuel consumption and pollutant emissions.
  • housings can be used comprising means for heating the coolant of the engine cooling circuit.
  • the box is connected to a first point of the cooling circuit via a first hose and to a second point of the cooling circuit via a second hose.
  • the coolant circulating in the cooling circuit passes through the first hose, is heated as it passes through the housing, then rejoins the cooling circuit through the second hose. Due to heating of the coolant, exhaust gas recirculation is activated more quickly.
  • the invention aims to provide a cooling circuit component of an internal combustion engine overcoming the aforementioned drawbacks.
  • the invention aims to allow the heating of the coolant while optimizing the heat exchange efficiency caused during heating, in order to limit fuel consumption and emissions of pollutants, and by limiting the size generated within the engine compartment.
  • a coolant passage conduit for an internal combustion engine of a motor vehicle comprising a tubular portion to allow the passage of a coolant from an engine cooling circuit, said tubular portion comprising an upstream end intended to be connected to a first functional member of the engine, and a downstream end opposite the upstream end and intended to be connected to a second functional member of the engine.
  • the tubular portion comprises at least one receiving orifice capable of receiving at least one element for heating the cooling liquid.
  • the passage conduit comprises a branch intended to be connected to a unit heater of the cooling circuit.
  • a branching makes it possible to directly bring the coolant having passed through the air heater to circulate through the second functional member of the engine.
  • Such a passage conduit makes it possible to heat the coolant while limiting the space generated within the engine compartment.
  • the coolant is heated near the engine so as to allow the engine to heat up more quickly. This improves the cold starting conditions to enable faster activation of the exhaust gas recirculation.
  • the heated passage duct further provides an additional heat source that helps warm a charge air cooler with anticipation. These effects notably result in better treatment of pollutants and lower fuel consumption.
  • the first functional member of the engine is an oil cooler and/or the second functional member of the engine is an engine cylinder block or a coolant pump.
  • Arranging the passage conduit fitted with a heating element between the oil cooler and the coolant pump, and in particular just upstream of the coolant pump, makes it possible in particular to circulate the liquid hot cooling in the water pump, which is close to the engine. This further heats the exhaust gases to open the exhaust gas recirculation valve even earlier and further heat the charge air cooler.
  • the passage conduit consists of a single piece made by molding, preferably in aluminum.
  • the passage conduit comprises at least four receiving orifices each capable of receiving a preheating plug.
  • glow plugs are particularly advantageous in that it makes it possible to sufficiently increase the engine load during regeneration of the particle filter.
  • Glow plugs are also known as immersion heaters.
  • said at least four receiving orifices are arranged in a staggered manner.
  • said at least one receiving orifice comprises a cylindrical bore of small diameter extending outwards from an internal wall of the tubular portion, and a cylindrical bore of large diameter extending towards the interior from a wall located outside the tubular portion, the two cylindrical bores being coaxial, the two cylindrical bores being connected by a frustoconical bore whose generators form an angle of between 58° and 66° with the common axial direction of said two cylindrical bores.
  • Such a design of said at least one receiving orifice allows easy installation of a preheating plug, while maintaining a reinforced seal of the coolant passage conduit.
  • the passage duct comprises an ear for fixing to a cylinder block of the engine.
  • Such an ear makes it possible to prevent the transmission of vibrations from the cylinder block to the passage duct.
  • an internal combustion engine for a motor vehicle comprising a cylinder block, a cooling circuit, a first functional member, a second functional member and a coolant passage conduit as defined above.
  • the engine comprises a coolant pump delimited by a pump housing, said pump housing being at least partially formed by a portion of the cylinder housing.
  • Such an embodiment is particularly advantageous in that the coolant heated by said at least one heating element is directly in contact with the cylinder block. As a result, thermal losses are minimized during the transfer of energy from the heated coolant to the internal combustion engine. In this way, by providing a minimum of energy, the temperature rise of the internal combustion engine is further increased so as to further limit fuel consumption and pollutant emissions.
