method for reducing nitrogen oxides in the exhaust gas flow of combustion engines |
| abstract |
method to reduce nitrogen oxides in the exhaust gas flow of combustion engines. a method is described to reduce nitrogen oxides in the exhaust gas flow of combustion engines, especially from a motor vehicle internal combustion engine, with the air / fuel mixture in the combustion engine combustion chamber being burned in the presence of a fuel additive and, in the process, the additive decomposes and the exhaust gas flow is directed through at least one catalyst arranged downstream of the combustion chamber. this method is characterized by the fact that a fuel additive is used, which decomposes in the combustion chamber, releasing ammonia, and the exhaust gas flow containing ammonia is directed through at least one scr catalyst disposed downstream of the chamber combustion to reduce the concentration of nitrogen oxides contained therein. the method according to the invention is highly effective in reducing the nitrogen oxide content in the exhaust gas flow of a combustion engine without the need for an exhaust gas after-treatment system after exhaust gas treatment which is expensive and requires expansion in the installation space. |
