Method and system for liquid fuel conditioning

A method of conditioning fuel and supplying conditioned fuel to a combustion process, the method which comprises:

• (a) providing a vessel for fuel conditioning, the vessel having a housing, at least one fuel dispersing nozzle, a gas inlet port, a conditioned fuel outlet port, at least one level sensor for registering a level of conditioned fuel in the vessel;
• (b) feeding liquid fuel into the vessel at a relatively high pressure P1 higher than a gas pressure P2 and thereby setting a pressure drop at the nozzle sufficient to satisfactorily disperse the fuel, and setting a volume of fuel flow through the nozzle sufficient for filling up the vessel at the rate not lower than a rate of the fuel consumption by a combustion chamber;
• (c) feeding at least one gas into the vessel through the gas inlet at the gas pressure P2 during the processes of fuel conditioning in the vessel and feeding conditioned fuel into a high-pressure fuel pump and further into the combustion chamber;
• and
• (d) conditioning more fuel and filling the vessel with fuel upon receiving from the sensor a signal registering low level of conditioned fuel in the vessel, and automatically switching the filling off upon receiving from the sensor a signal registering high level of conditioned fuel in the vessel.

In an internal combustion engine fuel delivery system, including a fuel injection system for injecting into a combustion chamber of the internal combustion engine, a fuel conditioning system, comprising:

• a vessel for fuel conditioning, said vessel having a housing and at least one fuel dispersing nozzle mounted therein and gas inlet port;
• a fuel outlet port and sensor for a conditioned fuel upper and lower levels control in said vessel;
• a low-pressure pump for providing liquid fuel flow at a low pressure to at least one dispersing nozzle mounted in said fuel conditioning vessel, the pressure being set to a level higher than a level of the gas pressure in said vessel to provide for a fuel pressure drop sufficient for satisfactory dispersion of fuel by said nozzle;
• a cylinder injection system including:
• a unit injector fuel supply system for feeding conditioned fuel to electronically controlled fuel injectors at a high pressure P3 exceeding a pressure P4 present in the combustion chamber of the internal combustion engine at the moment of injection and a liquid fuel supply line fluidically connecting an outlet port of said fuel conditioning vessel to inlet ports of said unit injectors fuel supply line;
• or
• a high-pressure fuel pump for feeding a liquid/gas fuel solution into a combustion chamber by means of a plurality of electronically controlled fuel injectors at a pressure higher than a pressure level in said combustion chamber at the moment of combustion;
• an electronic control system for providing timed start and duration optimization of operations of all electronically controlled devices for maximum fuel efficiency.
