INTERNAL COMBUSTION ENGINE COMPRISING A METHANE-DME (NATURAL GAS-DIMETHYL ETHER) FUEL SUPPLY SYSTEM AND METHOD FOR OPERATING THE INTERNAL COMBUSTION ENGINE

The present disclosure relates to a combustion process for an internal combustion engine, in which a fuel mixture composed of a dimethyl ether-containing first fuel and a methane-containing second fuel is combusted, wherein the premixed fuel mixture or the fuels independently are fed directly to at least one combustion chamber of the internal combustion engine and/or indirectly via at least one intake pipe of the internal combustion engine upstream of the at least one combustion chamber, wherein the fuel mixture present in the respective combustion chamber is combusted by self-ignition with addition of combustion air on the intake pipe side.
