System for finishing treatment of exhaust gases, for reduction of nitrogen oxides in exhaust gases of internal combustion engine, has solution, water, urea and reaction chamber

摘要

The system has a solution, water, urea and a reaction chamber. The units are provided to inject the solution into the reaction chamber. The solution has a tenside. The tenside has a hydrophilic functional group, which form a hydrogen bridge. The hydrophilic group is selected from carboxyl, carboxylate, hydroxyl, sulfone, sulfate, sulfonate, ammonium, amino, amide, polyether alcohols and betaines. The tenside has a lipophilic part made from hydrocarbon chains, dimethyl silicone catenae or fluorocarbon chains. An independent claim is also included for a method for reduction of nitrogen oxides in exhaust gases of internal combustion engine.
