Definitions

  • the present invention relates to the jets of piston cooling of an internal combustion engine, for projecting a cooling fluid such as oil on an appropriate area of the piston, and the engines fitted such jets.
  • the pistons cooling jets usually used are inserts attached to the crankcase and communicating with a coolant supply port.
  • the position of the nozzle is precisely determined to achieve a jet of cooling fluid directed to a specific area of the piston bottom or towards a piston gallery entrance.
  • US 4,206,726 discloses a jet whose fixing in a passage requires simultaneous access to the interior and outside the engine cylinder.
  • Documents FR 2 745 319 and JP 07 317519 describe a nozzle comprising a jet body with penetrating part shaped to engage axially in a housing bore motor and to receive the cooling fluid coming through said bore.
  • the nozzle has an exit structure having a radial passage of fluid in the jet body and having a outlet duct adapted to direct an outlet fluid jet towards the piston bottom zone to be cooled.
  • the nozzle must have a very high precision of the jet, because the entrance to the gallery is usually about 150 millimeters of the nozzle which is fixed on the crankcase, and the entry of the gallery is only 5 or 6 millimeters in diameter. In this small orifice, it is necessary to enter the maximum of fluid of cooling.
  • the jet must have a structure easy to manufacture, so as to be of a reduced cost adapted to a mass production in the automotive industry.
  • JP 07 317519 discloses a one-piece molded structure with two parallel ducts and one connecting ring which is complex and expensive.
  • the document FR 2 745 329 discloses a similar molded and reshaped monoblock conduit with a connecting ring.
  • the problem proposed by the present invention is design a new cooling jet structure, which can further improve the cooling capacity of the piston, for a given flow rate of cooling fluid, while remaining compatible with the very small space available in the engine to place such a cooling nozzle.
  • the invention also aims to conceive such a jet whose structure is particularly simple, to be made in a simple and inexpensive way in mass production.
  • the present invention results from the observation according to which it is certainly very good for cooling to put the maximum oil in a gallery entry of a piston, but failures may still result from an uneven distribution of the oil in the piston body.
  • the invention proposes a cooling nozzle for engine piston to internal combustion, having a nozzle body part shaped penetrant for axially engaging a bore of the motor in an axial direction of penetration and to receive a cooling fluid arriving through said bore;
  • the nozzle has an exit structure with at least one passage radial fluid in the nozzle body and with at least one first outlet duct and a second outlet duct adapted to direct the piston to cool at least two jets of separate coolants;
  • the first exit pipe includes a first outlet tube, attached to the body of nozzle, having a first radial connection section generally perpendicular to the axial direction of penetration, connecting in particular by an elbow to a first axial section of projection ending in a first hole, while the second outlet duct comprises a second outlet tube, having a second radial section of offset connection angularly away from the first radial connection section, connecting by an elbow to a second axial projection section ending with a second orifice.
  • the two jets of cooling fluid produced by this jet are substantially parallel to one another and spaced apart from each other by the distance generated by the radial sections angularly offset from each other.
  • the outlet tubes are connect to the nozzle body in two radial passages in which the proximal ends of the tubes of outlet are fitted and brazed.
  • two outlet tubes connect to the body of jet according to two radial passages separated by two sections connecting radials substantially perpendicular to each other by relative to each other and perpendicular to the axial direction of penetration, the first outlet tube having a connecting section developing in a generally parallel direction or convergent with respect to the radial connection section of the second outlet tube and connecting angularly on the one hand to the first radial section of connection by an elbow and secondly to a first axial projection section by a second elbow, so as to project the cooling fluid to two zones of the same piston clearly apart from each other while remaining at the distance of all moving parts in the engine cylinder.
  • the nozzle comprises a first outlet tube connected in a single radial passage to the jet body, the first outlet tube having the first orifice and having an intermediate section with larger diameter, which continues with a smaller diameter exit section, and connected to a second outlet tube having the second orifice.
  • the first output tube may comprise a upstream section and a downstream section connected to each other by a intermediate sleeve of larger diameter than the upstream sections and downstream, the upstream section being engaged by its ends respective in the radial passage of the jet body and in a first end of the sleeve, the downstream section being engaged in the second end of the sleeve, the sleeve being pierced with a hole side in which is engaged the upstream end of the second tube of exit.
  • an outlet tube receives at its downstream end an outlet end having two orifices outlet, the endpiece having an axial input hole engaging on the downstream end of the outlet tube and communicating with two holes divergent outputs intended to be oriented towards the zones of respective cooling of the piston.
  • the invention provides a motor with internal combustion comprising at least one nozzle with two tubes of outlet as defined above, the nozzle being shaped and positioned to create and direct at least two streams of fluid cooling to two respective gallery entrances dug into the mass of a piston.
  • At least one of the output tubes of the cooling nozzle can advantageously be bent from way around the piston along a portion of its circumference, allowing each of the jets to water the area concerned under the piston without ever being intercepted by the trajectory of the rod.
  • the two output tubes can advantageously direct the cooling fluid jets to two piston zones located on either side of its median plane. This allows to distribute the coolant even more equilibrium in the piston head surface, to improve the cooling.
  • a cooling nozzle 1 provided for to cool an internal combustion engine piston 8, has a nozzle body 2 having a penetrating portion 3 shaped for engage axially in an axial direction of penetration I-I in a bore of the engine to receive a fluid of cooling coming through said bore as illustrated by the arrow 4.
  • the cooling nozzle 1 further includes a output structure 5 protruding, communicating with the party penetrant 3, having an axial passage of fluid from the penetrating part 3, and comprising at least one radial passage 5a (and possibly 5b) fluid in the nozzle body 2.
  • the Cooling nozzle 1 has at least two outlet tubes 6 and 7.
  • Each outlet tube 6 or 7 is bent appropriately to position and orient their outlets 16 and 17 respective ones so as to create two jets of coolant 6a and 7a which are distinguished in FIGS. 2 and 8, and to direct the two jets 6a and 7a towards two zones of respective separate cooling 6b and 7b of the piston 8 of engine.
  • Each outlet tube 6 and 7 is an element reported by fitting and brazing, cut and formed from a tube stretched metal. This avoids having to mold and machine complex monoblock pieces. And we take advantage of the internal surface very smooth and regular stretched metal tubes, favoring a laminar flow of the fluid.
  • the first outlet tube 6 comprises a first section radial connection 6c, generally perpendicular to the axial direction of penetration I-I of the nozzle into the body of motor, and connecting in particular by a 6d elbow to a first axial projection section 6th to first orifice 16 which projects thus the jet of cooling fluid 6a in one direction generally axial with respect to the piston 8.
  • the second tube of output 7 has a second radial connection section 7c substantially perpendicular or strongly angulated with respect to first radial connection section 6c, and connected by a 7d elbow to a second axial projection section 7th to second orifice 17 which thus projects a jet of cooling fluid 7a in a generally axial direction, that is to say parallel to the axis of displacement of the piston 8 in the engine cylinder, the two jets of cooling fluid 6a, 7a being substantially away from each other.
  • two tubes 6 and 7 are connected to the nozzle body in two separate radial passages 5a and 5b respectively of the structure of output 5 by two radial connection sections 6c and 7c.
  • the connecting radial sections 6c and 7c are substantially perpendicular to each other and all two perpendicular to the axial direction I-I of penetration.
  • the first outlet tube 6 comprises a connecting section 6f developing in a generally parallel direction or convergent relative to the second radial connection section 7c of the second outlet tube 7, and being connected angularly with a part in the first radial connection section 6c by a 6d elbow and secondly to a first axial projection section 6e by a second bend 6g, as can be seen in Figure 3.
  • This form nozzle is adapted to project two jets of fluid from cooling to two zones of the same piston located on the on the other side of the median plane of the piston.
  • the two jets of cooling fluid 6a and 7a produced by the cooling nozzle 1 are directed respectively to two cooling zones 6b and 7b which are arranged on either side of the median plane M-M of the piston 8.
  • the two cooling zones 6b and 7b are two inlet openings of one or two galleries provided in the mass of the piston 8, so that the cooling fluid enters the gallery or galleries of the piston to propagate closer to the upper thrust surface 8e (FIG. 15) of the piston, which surface receives the heat energy of the combustion gases.
  • the cooling nozzles are arranged in an engine in the first half-space P containing the engine intake system, for congestion issues supply lines for cooling oil.
  • the hottest parts of the engine, and therefore the piston 8 are in the second half space S containing the exhaust system of the engine.
  • a cooling nozzle 1 which produces two jets of cooling fluid 6a and 7a on both sides of the median plane M-M, we can feed two gallery entries which communicate, by a gallery in the shape of a circular crown, or by two respective galleries in corner crown sector less than 180 °, with two respective piston zones 8a and 8b in the half-space S.
  • the cooling of the most hot 8a and 8b is well balanced.
  • the output structure comprises a first tube of outlet 6 which connects to the nozzle body according to a passage single radial 5a.
  • the first outlet tube 6 has the first orifice 16 and has an intermediate section 6h of larger diameter connected to the second outlet tube 7 which has the second orifice 17.
  • the first outlet tube 6 comprises an upstream section 6c1, a downstream section 6c2, a bend 6d and an axial section of projection 6th, and an intermediate sleeve 6c3 forming the section intermediate 6h of larger diameter than the upstream sections 6c1 and downstream 6c2.
  • the upstream section 6c1 is engaged by its ends respective in the radial nozzle passage 5a and in a first end of the sleeve 6c3.
  • the downstream section 6c2 is engaged in the second end of the sleeve 6c3.
  • the sleeve 6c3 is pierced with a lateral hole 6j in which the end is engaged upstream of the second outlet tube 7.
  • the upstream section 6c1 and the sleeve 6c3 are in one piece.
  • the spacing between the two jets of coolant 6a and 7a is important but the offset outward tubes are insufficient to place the orifices 16 and 17 on both sides of the median plane M-M.
  • nozzles having more than two output tubes to generate more than two jets of cooling fluid.
  • the nozzle must be spaced radially away from the axis A-A of the piston 8.
  • Figures 9 to 14 illustrate a nozzle of cooling having an outlet tube receiving a nozzle outlet for dividing the jet of coolant into two jets 6a and 7a.
  • a nozzle 1 having a nozzle body 2 with a penetrating portion 3 and a outlet structure 5 with radial passage 5a.
  • the outlet tip 10 has an axial input hole 10a shaped to be driven on the downstream end of the outlet tube 6, and communicating with two divergent exit holes 10b and 10c intended to be oriented towards the respective cooling zones of the piston. So, both 10b and 10c exit holes define the outlets respective ones 16 and 17 of the cooling nozzle.
  • the axial input hole 10a may advantageously have a cylindrical shape with circular section adapted to receive the cylindrical downstream end of the outlet tube 6.
  • the two exit holes 10b and 10c may have different diameters eg the exit hole 16 may have a diameter greater than the diameter of the exit hole 17.
  • the diameters are chosen so as to achieve a better distribution of outflow through each orifice, increasing the flow to irrigate the priority areas to be cooled, and reducing the flow to water the lower priority areas to cool.
  • the angles of orientation of the exit holes 10b and 10c are chosen to correspond to the locations of the zones of respective cooling of the piston. At their upstream end, outlet holes 10b and 10c are closer to each other, way to communicate directly with the inside of the outlet tube 6.
  • the outlet tip 10 comprises, on its peripheral face external, at least one plate 11 or 12 as illustrated on the FIGS. 9, 11 and 12, the plate 11 or 12 for locating and fix the angular position of the outlet tip 10 around the tube 6, for rotating the two holes of 16 and 17 during the assembly of the tip 10 on the tube of exit 6.
  • the outlet tip 10 can be used independently of the presence of other characteristics of number and shape of outlet tubes 6 and 7.
  • FIG. 16 illustrates in section the fitting of the outlet tube 7 in the radial passage 5b of the nozzle body 2, for the nozzle of Figure 3.
  • Figure 5 illustrates in section the fitting of the two tubes 6 and 7.
  • Figure 14 illustrates also the fitting of the outlet tube 6 in the body of jet 2.
  • the invention thus provides an internal combustion engine comprising at least one cooling nozzle 1 with two tubes of output 6 and 7 as previously defined, the nozzle of cooling 1 being shaped and positioned to create and directing at least two jets of coolant 6a and 7a to two entries of respective galleries 6b and 7b dug in the mass of a piston 8, as illustrated in Figures 1 and 2.
  • the outlet tubes 6 and 7 can to be bent so as to bypass the piston 8 according to a portion of its circumference and to be outside the trajectory of the piston 8 and connecting rod 9 during operation, leading thus axially the jets of cooling fluid 6a and 7a to two piston zones 6b and 7b located on either side of its median plane M-M. It can be seen in FIG. 2 that the second tube outlet 7 develops radially towards the center of the piston, while the first outlet tube 6 develops first by its section 6c along the periphery of the piston, then radially towards the center of the piston by its section 6f.
  • a nozzle according to FIGS. project two jets of cooling fluid to two zones 6b and 7b located on the same side of the median plane M-M, or to two zones 6b and 7b on both sides of the M-M plane.
  • the efficiency is reduced because the connecting rod 9 momentarily cuts the jet 7a during a portion of its travel cycle.
