Abstract
A flow guide (8) is provided for an exhaust system (3) of an internal combustion engine (1), especially in a motor vehicle. The flow guide (8) has at least one U-shaped guide plate body (13), which can be mounted with its U-base (14) on a pipe section (4′) of the exhaust system (3) and whose U-legs (15) form in the mounted state a flow guide plate (15) each. The flow guide plate cooperates with an exhaust gas stream (19) being guided in the pipe section (4′) during the operation of the exhaust system (3).
Claims16
A flow guide for an exhaust system of an internal combustion engine, the flow guide comprising:
- only a single U-shaped guide plate body including only a single U-base with a mounting surface for mounting on a pipe section of the exhaust system and with only two U-legs extending away from said mounting surface, each of said U-legs defining a flow guide plate, each said flow guide plate cooperating with an exhaust gas stream in the pipe section for guiding the exhaust gas stream in the pipe section during operation of the exhaust system,
- wherein:
- said U-shaped guide plate body is manufactured from a single piece of material;
- said single piece of material is a single piece of sheet metal;
- and
- each said flow guide plate has a guide profile, which is directed in parallel to a direction of said exhaust gas stream on an incoming flow side and which has an angle of incidence in relation to said direction of said exhaust gas stream on a discharge side.
An exhaust system for a vehicle internal combustion engine, the exhaust system comprising:
- a flow guide comprising a U-shaped guide plate body comprising only one U-base mounting surface positioned between only two U-legs extending away from said U-base mounting surface, each of said U-legs defining a flow guide plate;
- and
- an exhaust system pipe section with an inner pipe section surface, said flow guide being mounted with said mounting surface of said U-base on said inner pipe section surface of said exhaust system pipe section, each of said flow guide plates cooperating with an exhaust gas stream guided in said exhaust system pipe section during operation of the exhaust system, wherein:
- each said U-shaped guide plate body is manufactured from a single piece of material;
- said single piece of material is a single piece of sheet metal;
- and
- each said flow guide plate has a guide profile, which is directed in parallel to a direction of said exhaust gas stream on an incoming flow side and which has an angle of incidence in relation to said direction of said exhaust gas stream on a discharge side.
An exhaust system for a vehicle internal combustion engine, the exhaust system comprising:
- a flow guide comprising a U-shaped guide plate body comprising only one U-base mounting surface positioned between only two U-legs extending away from said U-base mounting surface, each of said U-legs defining a flow guide plate, said U-shaped guide plate body consisting of a single piece of sheet metal material;
- and
- an exhaust system pipe section with an inner pipe section surface, said flow guide being mounted with said mounting surface of said U-base on said inner pipe section surface of said exhaust system pipe section, each of said flow guide plates cooperating with an exhaust gas stream guided in said exhaust system pipe section during operation of the exhaust system,
- wherein:
- said inner pipe section surface has an inner pipe section surface contour;
- said mounting surface of said U-base has a contour corresponding to said inner pipe section surface contour;
- and
- each said flow guide plate has a guide profile, which is directed in parallel to a direction of said exhaust gas stream on an incoming flow side and which has an angle of incidence in relation to said direction of said exhaust gas stream on a discharge side.
