Definitions
- the invention relates to a mixing housing arrangement for an internal combustion engine with a housing having an intake duct section into which an exhaust gas recirculation introduction arrangement with an inlet opening and an outlet opening protrudes, and wherein the exhaust gas recirculation controllable by an exhaust gas recirculation valve is.
- Such a mixing housing arrangement is, for example, from DE - A1 - 199 01 318 known.
- this mixing housing arrangement there is the exhaust gas recirculation introduction arrangement from an independent component that is in recesses of the housing is used and held by means of snug fit sections becomes.
- This mixing housing arrangement is primarily in terms of assembly technology very complex and therefore expensive to manufacture. Based on this the invention has for its object a generic mixing housing arrangement to be designed so that the above-mentioned. Disadvantage is avoided.
- the exhaust gas recirculation introduction arrangement there is a housing part and a corresponding sealing element, the flow cross sections of the through cutouts in the sealing element Inlet opening and the outlet opening are determined.
- the exhaust gas recirculation introduction arrangement there is a housing part and a corresponding sealing element, the flow cross sections of the through cutouts in the sealing element Inlet opening and the outlet opening are determined.
- Air flow control throttle valve may be arranged upstream of the exhaust gas recirculation introduction arrangement.
- FIG. 1 shows a mixing housing assembly 1 for an internal combustion engine, not shown.
- a housing 2 has an intake duct section 3 through which Fresh air is fed to the internal combustion engine in a known manner. This is in Housing 2 arranged in a known manner, a throttle valve device 4 regulates the fresh air in the intake duct section 3. Exhaust gas is generated by an exhaust gas inlet arrangement 5 recycled, the exhaust gas entering through an inlet opening 6 and exits through an outlet opening 7 (see FIG. 2), and through an unillustrated one Exhaust gas recirculation valve is controlled.
- the housing 2 has a housing part 8, which in the present case is in the form of a shell Flow direction is open.
- FIG. 2 shows again the mixer housing assembly 1 with the mounted thereon Sealing element 9. It should be clear that one designed in this way Mixing housing arrangement with regard to the exhaust gas inlet simply to the engine-specific Circumstances.
