    摘要： An internal combustion engine assembly includes a fuel tank, connected via a fuel supply duct to a first fuel inlet of a cylinder, the cylinders with an outlet connected to an exhaust system. Exhaust gases from the exhaust system are in heat exchanging contact with a reformer unit for steam reforming of alcohol, the reformer unit being with a reformer outlet connected to a to a second fuel inlet of the cylinders for supplying hydrogen to the second fuel inlet. An alcohol evaporator is in heat exchanging contact with the exhaust gases. A water evaporator is in heat exchanging contact with the exhaust gases. A reformer purge duct extends from the exhaust system to the inlet of the reformer unit via a purge control valve, adapted for feeding exhaust gases into the reformer unit and via the reformer outlet to the second fuel inlet of the cylinders.

    摘要： Provided device for producing Hydrogen-enriched slush LNG fuel includes a vortex tube with a vortex chamber formed inside, a plurality of radial inlets installed on an outer surface of the vortex chamber through which a mixed fluid flows, a swirl generator provided inside the vortex chamber for the mixed fluid to flow inside the vortex tube and to cause a clockwise swirl motion, and a nozzle formed on the left side of the swirl generator, wherein a flow field is formed when pressure decreases to the left direction and pressure increases in the right direction from the central axis of the vortex tube, the high-temperature fluid discharges through the main tube to the right end of the vortex tube, and the low-temperature fluid discharges through the low-temperature fluid vent on the left side of the vortex tube.

    摘要： A fuel supply device includes a fuel injection valve, a delivery pipe, a relief passage, a first valve, and a second valve. The fuel injection valve injects gas fuel. The delivery pipe supplies the gas fuel to the fuel injection valve. The relief passage connects an intake passage of an internal combustion engine and the delivery pipe. The first valve is configured to supply the gas fuel in the delivery pipe to the relief passage. The second valve is arranged in the relief passage. The second valve opens when a downstream pressure becomes lower than an upstream pressure by an amount that is greater than or equal to a specified pressure determined in advance.
