Definitions

  • the invention relates to a switching intake manifold for an internal combustion engine with the features of the preamble of claim 1.
  • Switching intake pipes have become an indispensable component in engine construction. If the engine or the internal combustion engine has only one intake manifold length, a compromise in the form of a medium intake manifold length must be chosen. It is known that a shorter intake manifold helps enhance performance, a longer intake manifold on the other hand results in a higher torque in the un ⁇ direct speed range.
  • Switching suction pipes are known from the prior art, for example EP 0 814 244 AI, US 5 092 285, US 5 632 239, JP 3-182623 A, JP 4-12126 A, JP 07158457 A, which are each designed to be relatively bulky and thereby enlarge the installation space of the motor considerably.
  • Switching suction pipes are known from DE 196 12 036 AI and JP 07197817 A, which are of a more compact design than the aforementioned ones, but can only be used in V-engines up to a V-angle of at least 90 °.
  • the main main disadvantage of the aforementioned suction systems is the switching of the intake pipe lengths in each individual intake pipe by means of individual flaps.
  • the individual flaps sit on one or more shafts, have to be installed and synchronized and seal reliably.
  • assembly openings must be available or the distribution volume is chosen so large that an internal assembly is possible.
  • a large distributor volume leads to a poor engine response.
  • the many components are responsible for the high manufacturing costs.
  • the distributor chamber is divided by a longitudinal wall into two individual chambers, each of which is assigned to a length of intake manifold.
  • the individual chambers formed in this way each communicate with the individual intake pipes via the connection openings assigned to the associated intake pipe length.
  • the connection openings between the individual chambers and the associated individual suction pipes can be switched for opening and locking by rotating the rotary slide valve.
  • This known intake manifold also has a relatively large construction, since the outer diameter of this intake manifold results from the desired difference between the two intake manifold lengths. Accordingly, this switching intake manifold is difficult or unthinkable for use in a V engine with a V angle of less than 90 °.
  • a register air suction system which has two separate line systems with pairs of separate lines of different cross-sections to each inlet of the internal combustion engine and separate distribution chambers on the ends of the respective lines facing away from the machines.
  • a switching flap is arranged at the inlet of each of these distribution chambers, which can be opened and closed. the respective distribution chamber can be actuated.
  • one switching flap must be opened and the other switching flap closed, whereby a relatively large effort has to be carried out.
  • this known switching intake manifold is also very large and is therefore relatively unsuitable for use in V engines.
  • GB 2 121 473 A shows a further, very large switching intake manifold system which has a main distributor chamber which is connected to a secondary distributor chamber via a connecting pipe.
  • Single suction pipes extend from the secondary distributor chamber and are guided in such a way that they penetrate the main distributor chamber.
  • These individual suction pipes each have a connection opening in the section that runs within the main distribution chamber, via which the individual suction pipes can communicate with the main distribution chamber.
  • Each of these connection openings is assigned its own switching flap, which closes the connection opening in a first switching position and opens the connection opening in a second switching position and at the same time blocks the individual intake pipe upstream of the connection opening.
  • switching suction pipes should be compact so that they can be used, for example, in V-engines with a small V-angle, ner than 90 °, can be integrated.
  • Plastic is a very suitable material because the poorer thermal conductivity compared to aluminum or magnesium heats the intake air through the neighboring hot engine parts less quickly and this leads to a lower intake air temperature upstream of the inlet valve and thus to better filling and higher engine performance.
  • Plastic suction systems that enable multi-shell manufacturing are almost optimal when it comes to the decisive factors of weight and manufacturing costs.
  • Fig. 1 shows a cross section through a switching suction tube according to the invention
  • Fig. 2 shows a longitudinal section through the switching suction tube according to
  • a switching intake manifold 1 is shown, which can be used for an in-line three-cylinder engine, not shown, and is equipped with three switchable intake manifold lengths.
  • a distribution chamber 2 of the switching intake manifold 1 extends in the longitudinal direction of the engine and is greatly flattened in the direction of the engine.
  • This distributor chamber 2 is divided by partition walls in the distributor chamber 2 into three approximately large individual chambers 3, each individual chamber 3 being connected to three individual suction pipes 5 via three connecting openings 6.
  • each switching flap 7 is arranged between two individual chambers 3.
  • the combustion air In the drawn position of the lower switching flap 7 (cf. FIG. 2), the combustion air only reaches the lower individual chamber 3 in engine operation, since this flap position of the combustion air prevents the supply enters the middle and the upper single chamber 3 blocked.
  • the lower individual chamber 3 takes over the function of the distribution chamber for the three cylinders, while the middle and of course the upper individual chamber 3 are without function. With the lower single chamber 3, the longest suction pipe length is activated via the connection opening 6.
  • the upper switching flap 7 If the upper switching flap 7 is now actuated, it locks the middle single chamber 3 and releases the upper single chamber 3. In this way, the short switching tube length is active.
  • the switching suction tube 1 according to the invention takes up little space, consists of few parts, is easy to manufacture and reduces weight and manufacturing costs.

Abstract

L'invention concerne un conduit d'aspiration de commande pour un moteur à combustion interne comportant des conduits d'aspiration (5) qui présentent dans chaque cas des ouvertures de raccordement (6) le long de leur longueur, pour former différentes longueurs de conduits d'aspiration, avec lesquelles les conduits d'aspiration (5) individuels communiquent avec une chambre de distribution (2). Les longueurs des conduits d'aspiration individuels (5) peuvent être commutées avec des éléments de commande (7). La chambre de distribution (2) présente pour chaque longueur de conduit d'aspiration une chambre individuelle (3) qui communique dans chaque cas avec les conduits d'aspiration individuels (5) par l'intermédiaire des ouvertures de raccordement (6).
