Abstract
A purification component comprises at least one block for purifying exhaust gases, and a casing that defines a circulation channel for the exhaust gases extending along a longitudinal axis, and in which the purification block is housed. The casing comprises an inlet portion, an outlet portion, and a central portion arranged between the inlet portion and the outlet portion, and with the central portion surrounding the purification block. A thermal insulator covers the whole of the casing. The thermal insulator comprise a first part, having a first temperature resistance, arranged radially facing the purification block, and a second part, having a second temperature resistance greater than the first temperature resistance, covering at least the inlet portion of the casing.
