<p>Method and device for optimizing purification of diesel exhaust gases, the purification being carried out by using a catalyst. It is the object of the present invention to avoid the development of NO2 in the catalyst at the same time as the contents of carbon monoxide (CO) and hydrocarbons are maintained on a low level. This is carried out by adjusting the temperature of the exhaust gases when they pass the catalyst. The adjustment is carried out by finely divided injection of some cooling medium into the exhaust gases. </p> |
