Definitions

  • the invention relates to an intake manifold for an internal combustion engine made of plastic according to the preamble of the main claim.
  • an intake manifold for an internal combustion engine is known, which is made in one piece from plastic.
  • This suction manifold shows that it is possible to form both the connecting flange and the individual pipe pieces, which end in a common tubular extension, in one piece using plastic and to produce them in one operation.
  • the manufacturing process of such an intake manifold is, however, quite complex, so that previously particularly complicated shapes had to be dispensed with.
  • EP-PS 251 159 describes the use of a separate tube which is placed in the intake box and has openings which are arranged such that each cylinder is supplied with a certain amount of blow-by gases.
  • the invention has for its object to provide a suction pipe in a simple manner and without additional structural elements, which is designed such that air and / or blow-through gases are fed evenly to the individual intake pipes of the internal combustion engine. This problem is solved on the basis of the preamble of the subordinate main claims by their characteristic features.
  • the main idea of the invention is to design the supply of air or gas without machining the cylinder head or the engine block in such a way that they are introduced into the intake tract as close as possible to the valves. This also prevents any condensed water that may be introduced from icing up the intake tract. It is also achieved by the invention that no elements are required on the intake manifold, which unnecessarily complicate or make the manufacturing process of such an intake manifold unnecessarily.
  • An alternative solution to the task provides for a longitudinal bore to be arranged in the connecting flange of the intake manifold, from which transverse bores branch off into the regions of the individual intake openings.
  • a longitudinal bore is much easier to produce than in a cylinder head.
  • Such a longitudinal bore can also be suitable for avoiding material accumulations at certain points, which is usually done by ribbing or by making cavities. In this respect, such a hole can also contribute to the constructively favorable design of the intake manifold.
  • the openings through which the blow-by gas opens into the intake area are arranged in the immediate vicinity of the connection surface of the cylinder head.
  • these openings can be designed as slots that are attached to the connecting surface of the intake pipe. The closure of these slots is then inevitably formed by the connection surface of the cylinder head.
  • the introduction of these slots, in particular into a plastic part, is very easy to manufacture in terms of production technology.
  • the cross bores can have different diameters in order to achieve certain throttle cross sections which are suitable for ensuring that the blow-by gases are distributed evenly into the individual cylinders or to the individual valves. This means that the transverse bore first reached by the blow-by gas has the smallest diameter and these diameters increase in the direction of flow.
  • the adjacent intake pipes can be provided with a single connection for the blow-by gases, this connection opening into a slot which extends between the two pipe sections.
  • Another application of the longitudinal bore in the intake manifold is to use this bore to supply clean air, which is taken from the clean air flow of the air filter, to the valve seats of the injection valves.
  • These injection valves which are fastened directly above, in the area of the respective intake pipes in valve bores, require additional air in idle mode, which enables the fuel quantity injected to be better processed. This additional air is advantageously supplied to the individual valves via the longitudinal bore and the transverse bores branching off from it.
  • FIG. 1 shows the front part of an intake manifold 10 for an internal combustion engine with the individual intake pipes 11-18.
  • the intake manifold 10 is designed for an internal combustion engine which has four cylinders and two intake valves are provided per cylinder.
  • the intake manifold 10 is therefore divided into eight individual intake pipes 11-18.
  • the intake pipes are combined at their front end with a connecting flange 19.
  • This connecting flange is by means of screws or the like attached to a cylinder head 20 shown only hinted here.
  • connection bores in which connection elements 20, 21, 22 are fastened.
  • connection elements 23, 24 are fastened.
  • Each connection bore opens into a slot 25, 26, 27, 28, 29. This slot extends in each case between the two adjacent intake pipes and thus represents a passage through the respective connection element to the corresponding intake opening.
  • the blow-by gases which collect in the crankcase and must be returned to the intake tract, reach the connection elements 20-24 via a line (not shown here).
  • This line can consist, for example, of several hoses which are plugged onto the connection elements.
  • the surface of the cylinder head 30 facing the intake manifold forms a natural boundary of the slots 25-29.
  • the external intake pipes 11, 28 are each individually supplied with the blow-by gases via a connecting element 23, 24, so that it is ensured that the external ones Valves are provided with the same amount of blow-by gases as the internal valves.
  • Figure 1b shows the top view of the connecting flange.
  • the connecting flange 19 is further provided with two rows of bores 31, 32 for fastening the flange to the cylinder head.
  • the connection elements 20-24 are inserted into the corresponding bores and fastened in this bore, for example via a snap connection.
  • connecting flange 19 to be designed in such a way that the connection elements are superfluous, ie to provide this connection flange itself with fastening sockets onto which the hoses can be attached.
  • Figure 2 shows a variant of an intake manifold 10. This also has a connecting flange 19.
  • a longitudinal bore 33 is arranged in this connecting flange 19.
  • Cross bores 34 - 41 extend from this longitudinal bore 33.
  • the transverse bores each open into an intake pipe 11-18.
  • the longitudinal bore 33 is open on one side and is provided there with a connecting element 42, onto which a hose supplying the blow-by gases is attached.
  • the longitudinal bore 33 is located in the illustration shown here approximately in the middle of the connecting flange. Instead of such a bore, there is also the possibility of providing a longitudinal slot directly on the end face of the connecting flange 19 facing the cylinder head 30.
  • Cross slots extend from this longitudinal slot, which extend to the respective intake pipe. The production of such slots in a plastic molding is very simple, since no slides are required in an injection molding tool.
  • the intake manifold 10 shown in FIG. 3 contains the intake pipes 11, 12, 13, 14. Above the intake pipes, valve seats 43, 44, 45, 46 for injection valves are arranged. These injectors have to be flushed with clean air in idle mode, this clean air being supplied to the fuel via holes in the valves and causing a better swirling of the fuel.
  • a longitudinal bore 33 is shown in the intake manifold. This is provided with a connecting element 42.
  • the transverse bores 34, 35, 36, 37 extend from the longitudinal bore 33 and each lead to the inner wall of one of the valve seats 43 to 46. the longitudinal bore 33 is replaced by longitudinal slot 52.
  • valve 47 is shown in the valve seat 43.
  • This valve 47 is held in the valve seat via O-rings 48, 49 and has air inflow openings 50 on its circumference.
  • the longitudinal slot is closed by a cover element 51.
  • the slot 52 is also the possibility of designing the slot 52 as a longitudinal bore, as shown in FIG. 2.
