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 object is achieved on the basis of the preamble of the main claim by its characterizing 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 these are introduced as close as possible to the valves in the intake tract. 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 that unnecessarily complicate or increase the cost of the manufacturing process of such an intake manifold.
- a longitudinal bore is to be arranged in the connecting flange of the intake manifold, from which cross bores branch off into the areas 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 accumulation at certain points, which is usually done by ribbing or by making cavities. In this respect, such a bore can also contribute to the structurally advantageous 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 connecting surface of the cylinder head.
- these openings can be designed as slots that are attached to the connection 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 transverse 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 reached first by the blow-by gas has the smallest diameter and the diameter of the transverse bore increases in the direction of flow.
- One 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 when idling, which enables a better swirling of the injected fuel quantity.
- This additional air is advantageously supplied to the individual valves via the longitudinal bore and the transverse bores branching off from it.
- Figure 1 shows an intake manifold 10. This 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. It is also possible to provide a longitudinal slot instead of such a bore directly on the end face of the connecting flange 19 facing the cylinder head 30.
- Cross slots extend from this longitudinal slot, which extend as far as 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. 2 contains the intake pipes 11, 12, 13, 14. Valve seats 43, 44, 45, 46 for injection valves are arranged above the intake pipes. These injection valves 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 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 a 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. 1.
