ES8503078A1 - Atomising liquid fuel in engine injector or burner - Google Patents

Abstract

The arrangement is for atomising liquid fuel in combustion air in a carburettor or injector of an i.c. engine, jet propulsion unit or burner. Gas, pref. air (22) and/or carbon dioxide (20), is dissolved in the fuel under such pressure and temperature, that, at the subsequent temperature-pressure condition during mixing with combustion air, the fuel is over-saturated. - The fuel is pumped (41) into a mixer unit (11) where it receives the gas via a metering unit (29). A vortex chamber (163), mixing chamber (161) and outlet chamber (164) are arranged downstream of the unit (11) and the unit is controlled (R) in response to the fuel throughput in the chamber which is determined by a pressure gauge (46) or photo-sensor (51). (1/7) DEAB- DE3232938 C The method distributes liq. fuel in combustion air, particularly using of an injector. Gas, pref. carbon dioxide, is dissolved in the fuel at a pressure and temp. such as to exceed the saturation proportion at the mixing pressure and temp. at which the solution is delivered into the air. - The fuel can be fully saturated with the gas, and the solution pressure can be many atmospheres above the mixing pressure. The solution and mixing temps. can be approx. equal, or the mixing - temp. can be higher. - (8pp) EPAB- EP-118500 B Method of distributing liquid fuel in combustion air that the fuel is admixed through a carburetor or injector by which method prior to the admixture a gas preferably air and/or carbon dioxide is dissolved in the fuel, at a state of solution pressure and temperature at which a higher gas solubility of the gas is ensured that at the state of mixing pressure and temperature of the combustion air during admixture, in a quantitative ratio such that the saturation-quantity ratio is exceeded at the state of mixing pressure and temperature of the combustion air and the solution supplied to the carburator or injector, characterised in that the fuel is completely saturated with the gas at the state of the solution pressure and temperature and the fuel and the gas are continuously supplied regulated in a ratio corresponding to solubility into a gas to fuel mixer (11, 111, 112) from which the evolving solution and a gas bubble stream through a turbulent section (163), whereby the stream of gas bubbles is extensively oissolved, is supplied to a mixing dome (161) which is located above of the mixer (11, 111, 112) hence the solution is diverted into an exhaust section (164) wherein the saturated solution is directed downwardly with such a sinking speed that is lower than the speed at which the gas bubbles rise whereafter the saturated solution is fed to the carburetor respectively the injector (61, 65, 71, 81). (13pp) USAB- US4596210 A The fuel is forced by a pump (41) into the mixer (11), to which the gas is supplied through a flow regulator (29). Downstream of the mixer (11) are a turbulent section (163), a mixing dome (161), and an exhaust section (164) from which the solution is supplied free of bubbles to the carburettor or injector of an internal-combustion engine, a heating burner, or a reaction-engine burner. - The flow regulator is controlled in accordance with the throughput of fuel and regulated by a regulation device (R) in accordance with the percentage of gas in the mixing dome (161) as determined by a pressure gauge (46) or light sensor (51).
