Exhaust Gas System with a Gas Sensor, in Particular with a Particle Sensor
First Claim
1. An exhaust gas system, comprising:
- an exhaust gas pipe, through which exhaust gas flows in one flow direction, which exhaust gas pipe has a pipe wall;
a flange, which is arranged in the pipe wall and which has a passage opening provided with an internal thread;
a gas sensor, which is provided for sensing the exhaust gas, and which has a threaded housing portion provided with an external thread, which threaded housing portion is screwed into the passage opening, whereinan annular gap is provided between a radial exterior side of the threaded housing portion and an interior circumferential section of the passage opening, andthe flange has a flow guiding element, which extends along a downstream partial circumference of the threaded housing portion, and which is provided for limiting or largely preventing a flow around the gas sensor in the annular gap.

Abstract
An exhaust gas system includes an exhaust gas pipe through which exhaust gas flows in a flow direction and which has a pipe wall. A flange is arranged in the pipe wall and has a passage opening provided with an internal thread. A gas sensor, in particular a particle sensor, is provided for sensing the concentration of soot particles contained in the exhaust gas and has a threaded housing portion that is provided with an external thread and is screwed into the passage opening. An annular gap is produced between a radial outer face of the threaded housing portion and a passage-opening inner circumferential portion which protrudes into the interior of the exhaust gas pipe. The flange has a flow guiding element which extends over a downstream part of the circumference of the threaded housing portion and which is provided for limiting or largely preventing a flow around the gas sensor in the annular gap.
