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.

A system and attendant structural assembly operative to establish a coordinated mixture of gaseous and distillate fuels for an engine including an electronic control unit (ECU) operative to monitor predetermined engine data determinative of engine fuel requirements and structured to regulate ratios of the gaseous and distillate fuel of an operative fuel mixture for the engine. The system and assembly includes at least one mixing assembly comprising an integrated throttle body and air gas mixer directly connected to one another, wherein the throttle body is disposed in fluid communication with a pressurized gaseous fuel supply and the air gas mixer is disposed in fluid communication with a flow of intake air to a combustion section of the engine. In use, the throttle body is structured to direct a variable gaseous fuel flow directly to the air gas mixer for dispensing into the intake air flow to the combustion section.

In certain embodiments, a PFI diffuser induction device may use toroidal vortex flow to thoroughly mix H.sub.2 and air in the intake runner and port of a H.sub.2 engine. When H.sub.2 enters a stream of air flow in the form of a toroidal vortex, it may tend to swallow the air into the vortex where a low-pressure region may be formed due to the swirling velocity of the vortex, which may be more effective that the typical mixing via conventional injection methods. Engine test measurements show remarkable improvements in engine combustion stability as well as engine efficiency and power output using a counterflow Toroidal Vortex Induction Diffuser to achieve high levels of fuel mixture homogeneity in combustion engines using hard-to-mix fuels like H.sub.2, CH.sub.3OH, C.sub.2H.sub.5OH and other gaseous and liquid fuels.
