Abstract
In a method of controlling a dual fuel engine in which power in the form of a first gaseous fuel and in the form of a self-igniting second fuel is fed to at least one combustion chamber, a knock signal representative of the combustion chamber is detected. When a knock signal indicating a knock of at least a first intensity is detected, the amount of first fuel fed to the combustion chamber of the engine is increased, the increased introduction of power into the combustion chamber caused by the increase in the amount of first fuel being compensated by a corresponding reduction in the power contribution of the second fuel. When a knock signal indicating a knock of at least a second intensity greater than the first intensity is detected, the amount of first fuel is reduced.
