It includes at least a first and a second high-pressure fuel pump (100, 200) configured to pump fuel (105, 205) at a high pressure into a high-pressure fuel distribution line system (300) connected with the internal combustion engine (500). Each of the high-pressure fuel pumps (100, 200) is configured to be operated in a first pump mode and a second pump mode, such that in the first pump mode a first amount of fuel (105, 205) is pumped, said first amount of fuel being associated with a first engine output, and in the second pump mode a second amount of fuel (105, 205), said second amount of fuel being associated with a second engine output which is greater than the first output, is pumped. A control unit (400) is configured to alternately operate the at least two high-pressure fuel pumps (100, 200) such that during a first time period at least the first high-pressure fuel pump (100, 200) is operated in the first pump mode and at least the second high-pressure fuel pump (100, 200) is simultaneously operated in the second pump mode, and such that, during a second time period at least the second high-pressure fuel pump (100, 200) is operated in the first pump mode and at least the first high-pressure fuel pump (100, 200) is simultaneously operated in the second pump mode.

摘要： In a dual fuel engine operating on a main liquid fuel and a gas fuel, a pilot injector (390) is used to inject a pilot liquid fuel in the gas mode. In order to avoid knocking in the gas mode, the compression ratio of intake air is relatively low. When, for example, heavy fuel oil is used as the main liquid fuel, the pilot injector (390) is used to also provide an injection of a pilot liquid fuel such as diesel in the liquid fuel mode prior to the injection of the main liquid fuel to facilitate combustion of the main liquid fuel with the relatively low compression ratio.

摘要： In a dual fuel engine using the FCT technology, a new FCT configuration of an FCT shaft (42) is used to allow transitioning between a liquid fuel mode and a gaseous fuel mode at higher engine loads. According to the new configuration, a liquid fuel main injection is performed relatively late when switching from the liquid fuel mode to the gaseous fuel mode, and in a liquid fuel part load mode. The pilot injection system (60) of the engine is used to provide an early liquid fuel pilot injection during the transition and also in a liquid fuel part load mode to facilitate operating the engine in said mode with the late main injection timing.

摘要： A method for controlling operation of a dual fuel internal combustion engine is disclosed. The method comprises initiating an ending process of a gaseous fuel mode by stopping supply of gaseous fuel. During the ending process, combusting remaining gaseous fuel together with liquid fuel in a subgroup (12) of cylinders (8, 9, 10, 11).
