Abstract
A method is disclosed for cleaning a component of an exhaust aftertreatment system located downstream of a combustion engine in an exhaust flow path delimited by an outer wall. The exhaust aftertreatment system includes a first device releasably mounted in the outer wall upstream of the component and a second device releasably mounted in the outer wall downstream of the component, each of the devices being a sensor or an injector. The method includes sealing the exhaust flow path upstream of the first device and downstream of the second device, removing at least the first and second devices, thereby providing at least two openings in the outer wall, so that a cleaning flow path is provided, and introducing cleaning fluid into at least one of the openings, so that the cleaning fluid flows across the component via the cleaning flow path.
