Abstract: Method and system for the removal of noxious compounds from lean burning engines, the method comprising in series the steps of contacting the exhaust gas with a catalyst being active in oxidation of volatile organic compounds and carbon monoxide, passing the treated exhaust gas through a particulate filter catalysed with a first SCR catalyst, and passing the exhaust gas leaving the particulate filter through a second SCR catalyst, wherein ammonia is injected into the exhaust upstream of the catalysed particulate filter at a temperature below or at about 220° C. and wherein urea is injected into the exhaust gas between the first and the second SCR catalyst when the exhaust gas has reached a temperature of about 200° C.
