FIELD: machine building.
SUBSTANCE: proposed inventions can be used in exhaust systems and covers the method and device to adjust adding reducer at the point upstream higher than that the catalyst is located in the ICE exhaust manifold at. In compliance with the proposed invention, the reducer addition into inlet pipeline is adjusted subject to the results of comparison between the actual calculated accumulated amount (A1) and calculated preset accumulated amount (A2). The invention covers also a computer hardware unit incorporating a data carrier adapted for reading off by an electronic control unit and store computer program therein designed to force the said control unit to realise aforesaid method.
EFFECT: efficient method and device to adjust adding reducer at point upstream higher than that catalyst is located in ICE exhaust manifold at.
