A method in controlling a dual fuel internal combustion four-stroke piston engine (1) comprising - a number of cylinders (5), a piston (50) is movable in a reciprocating manner between a top dead center (TDC) and a bottom dead center (BDC) inside the cylinder (5) defining a combustion chamber, - the engine (1) is configured to operate in two modes: - a gas mode for using gaseous main fuel (10), and - a liquid fuel mode for using liquid fuel (20) injected directly to the cylinder (5), - the engine (1) is configured to switch between the modes when needed, - in a situation where a trip or other shift from the gas mode to the liquid mode occurs on a running engine (1), the liquid fuel (20) is injected during a combustion stroke after the piston (50) has passed the top dead center (TDC) when the piston (50) is already moving towards the bottom dead center (BDC). |
