Abstract

A process for controlling regeneration of a particulate filter of an internal combustion engine comprising determining the efficiency of a catalytic device provided in the exhaust upstream of the particulate filter and adjusting at least one operating parameter of the engine in order to increase the exhaust gas temperature upstream of the catalytic device to compensate for a reduction in efficiency of the catalytic device due to ageing.
