Abstract (en)
[origin: FR2850704A1] The process involves injecting diesel oil, up stream of an oxidation catalyst, from an electro-magnetic injector (9) for pulverizing the oil by compressed air. The temperature of an exhaust gas is increased to accelerate the speed of oxidation of the carbon particles for regenerating a filtration device of exhaust gas products. The temperature is increased when the start of binding of the particles is detected. An independent claim is also included for a device for post injection of diesel oil.
