A diesel engine can by high-pressure injection be supplied with both fuel oil and fuel gas. Each combustion in the cylinders of the engine is initiated by injection of fuel oil, and gas can be injected after initiation of the combustion. The gas share of the total fuel amount per combustion is adjustable, and the gas injection is prevented by a safety device in case of failing injection of fuel oil. When the share of gas of the total amount of fuel at a certain engine load is changed, the starting time for injection of fuel gas in relation to the starting time for injection of fuel oil is varied so that the gas injection is delayed when the gas share of the total amount of fuel is smaller, and vice versa.
