Abstract
The invention relates to a process for controlling a particulate filter in the exhaust of a Diesel engine using an after-treatment of the particulates while requiring a minimum amount of energy. The process according to the invention adapts the geometry of a filter placed in the exhaust gas flow according to predetermined strategies linked with the running of the engine, the process being such that it limits a mean back pressure of the engine which degrades engine efficiency.
