Definitions

  • the invention relates to a device for ensuring the supercharging of an internal combustion engine by means of a single turbo-compressor.
  • This solution has the disadvantage of being expensive and leading to poor average efficiency of the turbine which is not supplied for part of the time, for example. example about half the time with a four-cylinder engine.
  • a "puff converter” or “pulse converter” composed of two nozzles successively supplied by cylinders suitably offset in the order of ignition and followed by a conduit possibly forming a diffuser, connected to the inlet d '' a single turbine. If the section of the nozzles is sufficiently reduced, a satisfactory pressure drop can be obtained in the non-supplied manifold, but this arrangement has the double disadvantage of causing a loss of energy in the nozzles and of being effective only in narrow engine speed limits, making it unsuitable for automotive applications.
  • Patent DE-A-2143696 describes such a puff converter, with adjustable section, comprising a volute whose inlet, extended upstream, is divided into two conduits each provided with an adjustment flap.
  • the section of the turbine itself remains fixed.
  • the flap is arranged in such a way that the gases are projected towards the outside of the volute where it is well known that the speeds are normally lower than in the immediate vicinity of the wheel. There is therefore an explosion of the vein at the outlet of the narrowed sections of the puff converter and a significant loss of efficiency.
  • the invention proposes to provide a more effective solution to the problem set out above and to provide a surali device statement which is satisfactory for all engine operating speeds.
  • a supercharging device for an internal combustion engine comprising a turbo-compressor whose turbine comprises a volute connected to two pipes each connected to the exhausts of a group of cylinders of the engine, the inlet of the volute being divided by a partition in two conduits which extend the two pipes and which are each provided with an adjustment member.
  • said adjustment members are constituted by two extensions of an adjustment flap comprising a concave surface which constitutes a movable wall of the volute.
  • the invention also relates to a supercharged engine equipped with such a device.
  • FIG. 2 There is shown schematically in FIG. 2 an internal combustion engine M comprising four cylinders 1, 2, 3 and 4 and, in part, a turbo-compressor C.
  • the engine exhaust gases are channeled to two pipes 5 and 6 supplied by different cylinders suitably chosen in the order of ignition so that, for each pipe, the cylinders which are connected to them are offset by an angle at least 220 degrees measured on the engine crankshaft.
  • the tube 5 is connected to the cylinders 1 and 4, while the tube 6 is connected to the cylinders 2 and 3.
  • Tubing 5 and 6 are connected to a radial turbine 7, the body 8 of which delimits a volute 8 a in which rotates a wheel 9 which drives a compressor, not shown.
  • the inlet of the scroll 8a is divided, by a canvas 10, into two conduits 11, 12, which constitute extensions of the pipes 5 and 6, respectively.
  • the fabric 10 has a roughly triangular cross section and ends, downstream, by an edge 13 which is located upstream with respect to a section S of the volute 8 2 passing through its theoretical beak 14, so that the volute can be properly filled from the gas jet coming from each of the pipes 5 and 6.
  • a flap 15 received in a lateral housing 8b of the body 8, is hinged to the body about an axis 16. It includes a surface 17, preferably concave, which constitutes a movable wall of the volute making it possible to adjust its inlet section as a function of the conditions by any known means, for example using a rod 15 2 of axis Y or using a lever acting directly on axis 16.
  • the flap 15 has two extensions 18, 19 respectively penetrating inside the conduits 11 and 12. These extensions 18, 19 are separated by a slot 20 leaving the passage for the fabric 10 which extends laterally at 10a in the housing 8 b . They are terminated, each, by a cylindrical surface 21 of circular section centered on the axis 16 and cooperating with a conjugate surface 22 formed in the housing 8b , in order to ensure at least approximate sealing upstream of the shutter. Likewise, at least an approximate seal is ensured downstream of the shutter, by cooperation between two surfaces 23, 24, centered on the axis 16 and formed respectively on the shutter 15 and in the volute 8 a .
  • the kinetic energy of the gas jets at the outlet of the conduits 5 and 6 can be as high as necessary, without this resulting in significant loss, since this energy is directly used in the wheel 9 and the gases are always directed as close as possible to the wheel.
  • the invention applies in the same way if the flap 15 is followed downstream, as is known, by one or more other movable flaps intended to lengthen the area of the volute on which the section is adjusted.
