Cleanable device for depolluting an engine exhaust gases
First Claim
1. Device for depollution of the exhaust gases from a heat engine comprising an outer casing (23) delimiting a passage for circulation of the exhaust gases and, mounted in series in the said passage, a catalytic purification unit (18) and a particulate filter (20), the device comprising means for access to the upstream surface of the particulate filter, these access means comprising a transverse break (34) in the casing along its entire periphery, which break (34) separates the casing (23) into successive sections (38, 40), the device further comprising detachable means (36) for connection of the two successive sections along the said break, characterised in that the said detachable connection means (36) extend in a plane extending transversely with respect to the circulation passage and passing through one of the catalytic purification device (18) and of the particulate filter (20).

Abstract
A device for depolluting a heat engine exhaust gases includes an outer casing (23) defining a passage for the circulation of exhaust gases and, mounted in series in the passage, a catalytic purifying member (18) and a particulate filter (20). The casing (23) includes a transverse break (34) along its entire periphery, which break (34) divides the casing (23) into successive sections (38, 40), the device including a detachable device (36) connecting two successive sections along the break. The detachable connecting device (36) extends in a plane transverse to the gas circulation passage and passes through either the catalytic purifying member (18) or the particulate filter (20).
