METHOD FOR ENHANCING LATE OXIDATION IN A DUAL FUEL INTERNAL COMBUSTION ENGINE OF THE DIESEL-TYPE AND A DUAL FUEL INTERNAL COMBUSTION ENGINE OF THE DIESEL-TYPE OPERABLE ACCORDING TO SUCH METHOD

摘要

The present invention relates to method for enhancing late oxidation in a dual fuel internal combustion engine of the diesel-type, comprising a combustion chamber being at least partly delimited by a piston, a first fuel supply for a first fuel, said first fuel supply being located in or at the combustion chamber and/or in an inlet port thereof, and a second fuel supply for a second fuel, the method comprising the steps of: • pre-mixing said first fuel in said combustion chamber and/or in said inlet port, • compressing the charge containing the first fuel to conditions close to homogeneous charge compression ignition of said first fuel, • performing a first injection of the second fuel into said combustion chamber to initiate auto-ignition of said second fuel and subsequently said first fuel, further comprising the step of • performing at least one subsequent injection, said subsequent injection supplying additional kinetic energy into the combustion process to thereby enhance late mixing in the combustion chamber, so as to improve late oxidation during combustion. The invention also relates to a dual fuel internal combustion engine of the diesel-type.
