摘要： 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.

摘要： A piston is positioned for reciprocal movement in a combustion engine cylinder. Half way between flame plume impingement areas are arranged a first type of protrusions protruding into the combustion chamber and having a smooth form adapted for preserving kinetic energy in a flame plume. Each of the first type of protrusions has a shape of a longitudinal ridge that extends only in the outer bowl area. The first type of protrusions have a left side flank and a right side flank of the ridge when seen from the injector. The left side flank is formed differently compared to the right side flank in order to redirect the movement of a flame plume progressing towards the left side flank in a plane perpendicular to the reciprocal movement, differently compared to corresponding flame plume progressing, towards the right side flank.
