Forming opening in exhaust pipe for reception of Lambda probe for internal combustion engine of motor vehicle

摘要

The opening for the lambda probe is carried out using a shaped bit (14), which is axially rotated and acted on with a predetermined force in such a manner, so that its tip (18) is pressed against the exhaust pipe wall (12). So that the required opening is formed by the flowing of a material of the exhaust pipe. The shaped bit is conically designed.
