    Abstract: A power system for a work vehicle, includes an intake arrangement configured to intake charge air; a fuel arrangement configured to provide at least one fuel; a compression ignition engine including a plurality of piston-cylinder sets configured to receive, ignite, and combust the at least one fuel from the fuel arrangement and intake gas that includes the charge air from the intake arrangement to generate mechanical power and exhaust gas; at least one compression ignition assistance apparatus associated with at least one of the intake arrangement and the fuel arrangement; and a controller coupled to command the compression ignition assistance apparatus, the intake arrangement, and the fuel arrangement such that, in an enhancement mode, the controller commands activation of the compression ignition assistance apparatus; and in a nominal mode, the controller commands or maintains deactivation of the compression ignition assistance apparatus.

    Abstract: A method of controlling fuel injection in a dual fuel engine system includes determining, with a first controller, a diesel injection pulse indicative of a first amount of diesel fuel to be injected into a combustion chamber of the engine and a first timing at which the first amount of diesel fuel is to be injected. The method also includes determining, with a second controller, a combined injection pulse based on the diesel injection pulse. The method further includes injecting the second amount of diesel fuel and the third amount of natural gas into the combustion chamber in accordance with the combined injection pulse. In such a method, injection in accordance with the combined injection pulse results in a combustion event characterized by a second combustion characteristic substantially equal to a first combustion characteristic associated with the diesel injection pulse.

    Abstract: A device capable of supplying an internal combustion engine with fuel while improving the utilization rate of vaporized fuel. A temporary transition from a third state (primary recovery path FL1: closed, secondary recovery path FL2: closed, second vaporized fuel path VL2: closed, condenser 30: decompressed) to a fourth state (primary recovery path FL1: closed, secondary recovery path FL2: closed, second vaporized fuel path VL2: open, condenser 30: decompressed) is achieved. This temporarily increases an internal air pressure P of a condenser 30, and the kinetic energy of a vaporized fuel V leaked out of a first fuel tank 40 through the second vaporized fuel path VL2 is able to sweep away a first fuel F1 in a liquid state accumulated in a vacuum pump 36 to the first fuel tank 40.
