ARRANGEMENT FOR FITTING AN EXHAUST CLEANING UNIT IN AN EXHAUST PASSAGE

摘要

The present invention relates to an arrangement for fitting an exhaust cleaning unit (2) in an exhaust passage (1b). The arrangement comprises an annular resilient component (7) which is fitted round the exhaust cleaning unit (2) at a distance from the gasket (5). The annular resilient component (7) has a first contact portion (7a) adapted to coming into contact with a wall surface (3) of the exhaust cleaning unit (2) and a second contact portion (7b) adapted to coming into contact with a wall surface (1b) of the exhaust passage when the exhaust cleaning unit (2) is in a fitted state in the exhaust passage and that the annular resilient component (7) has the characteristic of keeping the exhaust cleaning unit (2) in a centred position in the exhaust passage with a spring force.
