Abstract

See full text

A method of operating a dual fuel internal combustion engine of the diesel-type is provided. The method includes pre-mixing a first fuel in a combustion chamber and/or in an inlet port, compressing a charge containing the first fuel to conditions that allow auto-ignition of a second fuel, performing a first injection of the second fuel into the combustion chamber to initiate auto-ignition of the second fuel for igniting the first fuel, thereby initiating conditions for pre-mixed flame propagation combustion of the first fuel. At least one subsequent injection is performed in which additional kinetic energy is supplied into the combustion process to thereby enhance turbulence intensity and propagation speed of the flame and/or enhance late mixing in the combustion chamber, so a to improve late oxidation during combustion. A dual fuel combustion engine of the diesel engine type.
