A method of increasing the overall efficiency of an engine while maintaining nitrogen oxide emissions from internal combustion engines and the apparatus for this

摘要

The invention relates to a method for increasing the overall efficiency of an engine while maintaining nitrogen oxide emissions from internal combustion engines, in which a mixture of methane, carbon dioxide, carbon monoxide and hydrogen is added to the fuel and / or fuel / air mixture to produce a final fuel composition in the combustion chamber. 36 to 51% by volume, carbon dioxide 27 to 35% by volume, carbon monoxide 16 to 21% by volume and hydrogen 4 to 6% by volume, after which the proportion of fuel and combustion air is adjusted on the basis of the fuel composition in the combustion chamber and / or or the ignition advance angle and / or the engine compression ratio and / or the boost pressure in the engine intake / charge system. It further relates to a device for carrying out this method, wherein the fuel system of the engine (2) and / or the intake system (1) of the engine (2) and / or the cylinder of the internal combustion engine (2) is provided with a feed of a mixture of methane, carbon dioxide, carbon monoxide and hydrogen. connected to the control.
