Definitions
- the invention relates to an intake device that is particularly suitable for use in an internal combustion engine.
- an intake device which includes a channel u which opens into a cylinder of an internal combustion engine.
- An asymmetrically designed swirl flap is arranged in the channel, which generates a swirl flow (swirl flow) in the cylinder of the internal combustion engine in a predetermined position.
- Flaps of this type are used to generate such a flow in the cylinder in the cylinder of the internal combustion engine in predetermined operating states that extremely lean operation of the internal combustion engine is possible.
- the object of the invention is to provide an intake device by means of which low exhaust gas emissions are ensured.
- the invention is based on the knowledge that fuel accumulations can form in the region downstream of the flap and that this can be prevented in a surprising manner by recesses.
- FIG. 1 shows a section through a suction device with a ner flap
- Figure 2 the flap according to Figure 1
- Figure 3 shows another embodiment of the flap according to Figure
- An intake device (FIG. 1) comprises an intake manifold 1, which is led from a collector of the intake device, not shown, to an inlet channel of a cylinder which is formed in a cylinder head of an internal combustion engine.
- a collector of the intake device not shown
- the intake device also has a flange 3, via which the intake device can be attached to the cylinder head of the internal combustion engine.
- a flap 5 is formed in the intake manifold 1.
- the flap 5 is mounted on a shaft 7, preferably eccentrically.
- the flap 5 is shown in a position in which it is pivoted into the intake manifold 1 and only releases a small part of its cross section for the gas mass flow flowing in a main flow direction 9.
- the flap 5 can also be pivoted into the bulge 10, so that essentially the entire cross section of the intake manifold is then released and the gas mass flow is unimpeded in the main flow direction from the collector through the intake manifold to the cylinder of the internal combustion engine can flow.
- an injection valve 17 is also provided in the intake manifold 1, to which fuel is supplied via a fuel supply line 19 and which injects the fuel into the intake manifold.
- the flap 5 is designed and arranged in such a way that it either generates a tumble flow in the cylinder, as is the case in the embodiment according to FIG. 1, or generates a swirl flow in the cylinder.
- part of the gas mass flow flows in the main flow direction through recesses 11 to 16 of the flap into the area directly downstream of the flap.
- the recesses extend from the side of the flap 5 which faces the main flow direction 9 in the channel to the side which faces away from the main flow direction 9 in the intake manifold.
- a plurality of recesses are provided in the flap, which can simply be designed as bores, which enables the flap 5 to be produced economically.
- the holes can be circular, ring-shaped or slit-shaped. Bores are characterized by the fact that they lead to a static pressure equalization downstream of the valve, which means that fuel accumulations are almost completely avoided.
- the bores have a very small diameter of e.g. B. 0.5 - 2 mm.
- B 0.5 - 2 mm.
- a particularly good current In the intake manifold 1 this results when the bores are evenly distributed over the flap surface. This then has the advantage that fuel accumulations downstream of the flap can also be avoided particularly efficiently.
- flap 5 is arranged in the channel designed as intake manifold 1. However, it can of course also be arranged in an inlet channel to the cylinder of the internal combustion engine in the cylinder head of the internal combustion engine.
- FIG. 3 shows a further embodiment of the flap 5, which here is designed as an airfoil with tangential, obliquely arranged bores (11, 12, 13).
