Abstract
A method is described for preventing early degradation of an exhaust treatment device installed in a diesel powered vehicle, the treatment device having an active element located within a casing by means of a mat surrounding the active element. The method comprises temporarily operating the engine at an early stage following the installation of the exhaust treatment device in an alternative mode wherein the temperature of the exhaust treatment device is raised sufficiently to cause the mat surrounding the active element of the exhaust treatment device to pop.
