Abstract: Presented a method and a system for improving atomization of heavy fuel oil or diesel fuel in heavy duty diesel engines, e.g. marine engines, wherein before injection into a combustion chamber the fuel is treated by gas/gases under elevated pressure of about 500 psi in an absorber; the heavy fuel oil/diesel fuel is fed to the absorber's dispensing means at a pressure of 1100 psi; a resulted fuel solution without a free gas phase is further mixed with a recirculating fuel stream forming a mixed fuel stream; the mixed fuel stream is directed for injection into a combustion chamber.

Abstract: The present invention relates to a system and method for providing fuel to internal combustion engines including fuel activation prior to injection. The method carried out by the system comprises dissolving a mixture of gasses providing improved fuel dispersing after fuel injection into a combustion chamber. Dissolved gasses desorption is stimulated from a unsaturated fuel solution. Full control of fuel flows with dissolved gas/gasses to and from injectors and FET technology based on Henry's law (dissolving gasses in the liquids) and Kelvin principle (vapor pressure over droplet surface). The system consists of compact components, including exhaust gasses recirculation system which can be easily added to existing diesel and gasoline engine fuel supply systems. The method and system were tested with four different types of engines and provides fuel economy in 12-20% decrease of emissions and up to 25% at variable engine loads and significantly at engine cold start.

Abstract: A method is provided for supplying a liquid fuel to a gas-turbine engine, e.g. aviation engine. It includes selective fuel delivery through several fuel delivery lines for different engine operating modes based on a required engine power, providing, e.g. feeding the engine operating at minimal power with base or traditional for this type of engine fuel through a base fuel delivery line; in other operating modes the fuel is fed to the engine either through conditioned fuel delivery line with preliminary conditioning of base fuel or through both said fuel delivery lines simultaneously with mixing both fuel flows directly before entering an engine combustion chamber, e.g., in a line connecting intake manifold for the base fuel and each individual fuel injector.

Abstract: A fuel is conditioned in a fuel supply system for more efficient combustion in a combustion chamber. The conditioning system includes a fuel vessel for fuel conditioning, at least one fuel dispersing nozzle mounted for discharge into the fuel vessel, at least one gas inlet port and at least one conditioned fuel outlet. A low level sensor registers a lower level of conditioned fuel in the fuel vessel. A high level sensor registers an upper level of conditioned fuel in the fuel vessel. A gas source feeds a gas to the fuel vessel, wherein the gas is dissolved in the liquid fuel for forming a liquid/gas fuel solution. A low-pressure fuel pump and a liquid fuel supply line supply liquid fuel from a fuel reservoir to the at least one dispersing nozzle of the fuel vessel at a pressure P1 higher than the gas pressure P2. A needle valve positioned downstream the fuel chamber, lowers the pressure, created in the fuel chamber by gas pressure P2, to lower level P3 downstream the needle valve.
