METHOD TO REDUCE EMISSIONS OF NITROGEN OXIDES FROM COMBUSTION ENGINES AND/OR TO INCREASE THE PERFORMANCE OF COMBUSTION ENGINES WHILE KEEPING THE EMISSIONS OF NITROGEN OXIDES FROM COMBUSTION ENGINES AT THE SAME LEVEL AND/OR TO INCREASE THE OVERALL PERFORMANCE OF AN ENGINE, AND A DEVICE TO PERFORM THIS METHOD

摘要

A method to reduce emissions of nitrogen oxides from combustion engines and/or to increase the performance of combustion engines while keeping the emissions of nitrogen oxides from combustion engines at the same level and/or to increase the overall performance of an engine. Carbon dioxide is added to the fuel and/or air/fuel mixture at a rate of 1 to 90% by mass in the fuel/carbon dioxide mixture in the combustion area and, depending on its quantity, the air/fuel ratio and/or the pre-ignition fuel injection and/or the engine's compression rate and/or the feeding pressure in the engine's suction system is adjusted. The invention also relates to a device to perform this method, wherein the fuel system of the engine (2) and/or the suction system (1) of the engine (2) and/or the cylinder of the internal combustion engine (2) is complemented with carbon dioxide supply.
