Definitions

  • the invention relates to a preamble of claim 1
  • Collector of a suction system for a V engine, in particular V8 engine the collectors arranged adjacent to the cylinder banks by means of inlet lines is equipped with two intake pipes and the collector also has one essentially centrally arranged, having an opening in a partition Chamber on the motor side and is divided into an overlying chamber remote from the motor.
  • a collector with the generic features is for example from DE-A 196 05 308 known.
  • the breakthrough depends on the company controllable flap assigned with the aim of controlled subdivision approximately equal partial volumes to achieve one of the predetermined firing order of the respective V-machine corresponding air supply to the inlet lines of the Cylinder in both cylinder banks.
  • this previously known collector the intake pipes upstream of their fresh air connections depending on the operating point Exhaust gas supplied, with a flap-controlled subdivision of the collector in two chambers with each supplied exhaust gas / fresh air mixture due to this the ignition sequence correctly connected to the chambers on all V-engine cylinder is distributed substantially uniformly.
  • the invention has for its object a generic collector in this way to design that in a structurally simple manner, an equalization of the exhaust gas / fresh air mixture is achieved on all cylinders of the V-engine.
  • V-engine With the cessation of ignition lines correctly connected to the controllable chambers the V-engine is advantageously a collector with a simple structure achieved.
  • Embodiment of the invention proposed that the partition is a central arranged opening has with at their respective distance from the mouths of all inlet lines in the motomahe suction chamber coordinated boundary. With this border arranged according to the invention can be promoted cylinder-specific distribution in an advantageous manner.
  • a relatively long mixing section for which in A further embodiment proposes that the mixing chamber remote from the motor connected intake pipes for a first mixing section of fresh air and correspondingly supplied exhaust gas upstream of the intake pipe flanges Have length.
  • a suction system, not shown, for a V8 engine, not shown, includes one Collector 100, the cylinder banks of the V8 engine, not shown, by means of intake lines 1 to 4 and 5 to 8 is arranged adjacent and with two intake pipes 9, 9 'is equipped. Furthermore, the collector 100 is essentially one centrally arranged, with an opening 10 having a partition 11 in a Chamber 12 on the engine side and divided into an overlying chamber 13 remote from the engine.
  • Collector 100 designed so that all inlet lines 1 to 4 and 5 to 8 with the motor-side chamber 12 are in medium-connection and that both intake pipes supplying an exhaust gas / fresh air mixture depending on the operating point 9, 9 'are connected to the chamber 13, which is remote from the motor, in a medium-carrying manner.
  • the partition 11 has a centrally arranged Opening 10 on with one at their respective distance from the mouths All inlet lines 1 to 4 and 5 to 8 in the suction chamber close to the engine 12 coordinated border 14.

    toutes les conduites d'admission (1-4, 5-8) communiquent avec la chambre (12) du côté du moteur pour le passage du fluide, et
    les deux tubulures d'aspiration (9, 9') sont reliées à la chambre (13) éloignée du moteur, par une liaison de passage de fluide,
    caractérisé en ce que
    les deux tubulures d'aspiration (9, 9') conduisent à un mélange gaz d'échappement-air frais suivant le point de fonctionnement.
  2. Collecteur selon la revendication 1,
    caractérisé en ce que
    le passage (10) est central et comporte, dans son éloignement respectif par rapport à l'embouchure de toutes les conduites d'admission (1-4, 5-8), un bord (14) accordé dans la chambre (12) du côté du moteur.
  3. Collecteur selon l'une quelconque des revendications 1 et 2,
    caractérisé en ce que
