Definitions
- Engine assembly with a cylinder head and a flange arranged upstream of the cylinder head
- the invention relates to an engine assembly according to the preamble of claim 1 with a cylinder head, in which as an inlet channel for at least one cylinder
- Single inlet channel guide is provided with at least two channels, and a
- the invention relates to motor assemblies for motors with single inlet channel guide, in which an intermediate flange is used, in particular as a connecting element between a
- Air duct in particular a so-called filling channel and the second air duct to a so-called tangential channel for generating a twist.
- Under intake manifold integrated intercoolers are in particular those intercoolers understood in which in the intake manifold of an internal combustion engine - especially liquid-based - heat exchanger is integrated to extract air to be supplied to the combustion chamber of an internal combustion engine immediately before flowing into the combustion chamber and thus heat to allow the introduction of a larger mass of air into the combustion chamber.
- Such an intermediate flange usually has a thickness (i.e., extent in the flow direction) of about 10 mm to 30 mm and has the function of allowing a straight connection of the intake manifold integrated intercooler.
- Cylinder head air outlet is called.
- the intake manifold is attached to the cylinder head and defines an intake air passage in communication with the cylinder head air passage. Between the intake manifold and the cylinder head, a seal is arranged.
- the gasket includes a gasket member and an airflow directing member, wherein the airflow directing member extends into the cylinder head air passage to direct air flow from the intake air passage into the cylinder head air passage.
- the invention has for its object to improve a motor assembly according to the preamble of claim 1 fluidly in particular so that the flow and / or the swirl are increased so as to improve the efficiency of the engine.

- at least one air duct is formed in the flange whose boundary wall is adapted to the cylinder head in the connection region such that at least over a part of the circumference in a connection region to the cylinder head results in a continuous wall course.
- the at least one air duct in the flange which air to the first air duct and the at least second air duct in the cylinder head conducts, at least partially fluidly adapted so that at least partially no transitional edges are present in the connection area between the flange and the cylinder head, which cause flow losses due to flow breaks (in the flow direction receding edges) or additional flow resistance (protruding edges in the flow direction).
- An especially positive effect is an adaptation in the connection area between flange and cylinder head.
- connection area between the flange and the cylinder head completely correspond, i. E. have a continuous wall course without edges in the connection area.

- the flange is an intermediate flange which, as a separately formed component, establishes a connection between an intercooler or another element and the cylinder head.
- Intermediate flanges usually have only a limited component thickness of usually less than 100 mm, usually even less than 50 mm. At such components can be easily and inexpensively complex geometries form, since the thickness and thus the required machining depth is small and the

- air flows from the first air duct of the
- Air duct formed from the cylinder head through the flange into the intercooler as a functional unit with air guide function As a result, the efficiency of a motor can be increased particularly by increasing the flow and / or the twist.
- the geometries formed in the cylinder head of the air ducts continue analogously in the flange and insofar as the air ducts in the flange are direct extensions of the air ducts in the cylinder head (upstream of the cylinder head, i.e. counter to the flow direction).
- the geometries of a first and at least a second channel can also - as described above in connection with the connection region between a flange and a cylinder head - be continued analogously in a further component, which is arranged upstream of the flange, in particular in an outer wall of a suction pipe integrated intercooler.
- the continuation of the geometry can be regarded in this case as an extension of the flow channels leading to the cylinder.
- Connection area adapted to the flange and / or the at least second
- Connection area adapted to the flange.
- Air duct in the cylinder head in the connection area is adapted to the flange and / or the at least second air duct in the flange in the connection area to the cylinder head over the circumference is completely adapted to the at least second air duct of the cylinder head in the connection area to the flange.
- the first air duct formed in the flange and / or the at least second air duct formed in the flange are designed to taper in the direction of flow. Again, this may occur only over part of the circumference, for example over one side of the air duct or over a certain angular range (e.g., over 90 ° or 180 °) or over the entire circumference.

- the invention has been developed in particular for an engine arrangement in which the first air duct and the at least second air duct in the cylinder head have different cross-sectional shapes. This is the case in particular if the first air duct is a so-called filling duct and the second air duct is a so-called tangential duct. With a filling channel, which is usually a round one
- Air duct and the at least second air duct in the cylinder head have different cross-sectional shapes are preferably used for the first air duct and an optional at least second air duct in the flange corresponding cross-sectional shapes.
- the first air duct of a flange and / or the at least second air duct of a flange, which at least partially have a tapered outer wall, these tapered outer walls as draft angles of a Cast manufactured flange are designed.
- the flange can be made as a casting that does not need to be post-machined to achieve the desired geometry.
