Method of reducing nitrogen oxide emissions from exhaust of internal combustion engines and/or increasing performance of internal combustion engines while maintaining nitrogen oxide emissions from exhaust of internal combustion engines and/or increas

摘要

BACKGROUND OF THE INVENTION The present invention relates to a method for reducing nitrogen oxide emissions from internal combustion engines and / or increasing combustion engine performance while maintaining nitrogen oxide emissions from internal combustion engines and / or increasing overall engine efficiency. Carbon dioxide is added to the fuel and / or fuel / air mixture in an amount corresponding to 1 to 90% by weight. in the fuel / carbon dioxide mixture in the combustion chamber and based on its amount, the proportion of fuel and combustion air and / or the advance / fuel injection rate and / or the engine compression ratio and / or the filling pressure in the engine intake system are adjusted. Furthermore, the invention relates to a device for carrying out this method in which the engine fuel system (2) and / or the engine intake system (1) and / or the engine cylinder (2) is provided with a carbon dioxide feed.
