Patent

CA 2323359

A cost-effective solution to removing particulates from diesel, especially light-duty diesel engines incorporates an oxidation catalyst (2) effective to convert NO in the exhaust from the engine to NO2 and a particulate trap (4) which traps no more than 85 % by weight of the particulate, optionally by permitting gas to by-pass the trap.

L'invention concerne un système rentable qui permet d'éliminer les particules dans les émissions des moteurs diesel, en particulier les moteurs à faible puissance, comprenant un catalyseur d'oxydation (2) dont l'action est efficace pour la conversion de NO en NO2, et un piège à particules (4) emprisonnant au maximum 85 % des particules, en poids, éventuellement avec contournement du piège par les gaz.
