Abstract (en)
[origin: US2006096274A1] A post-injection method for the regeneration of a device used to filter diesel engine exhaust gases. The method includes injecting a fully-pulverised hydrocarbon-, alcohol- and/or reducing-agent-type regeneration solution upstream of the oxidation catalyst ( 14 ) to increase the exhaust gases' temperature upon detection of clogging of the filter with particles. A computer uses temperature ( 2 ) and pressure ( 3 ) sensors disposed upstream of the filtration device to control injection of the regeneration solution from an electromagnetic injector ( 9 ). The regeneration solution is directed through a capillary ( 12 ) into the exhaust pipe ( 1 ) at a point located at a good distance from the injector, upstream of the catalyst ( 5 ), in order to be finely pulverised by the air.
