The application for the invention of the Russian Federation FIPS number 2004134421
The decision to grant a patent on 2.02 2005
The invention relates to cooking devices of the fuel mixture in any thermal systems containing fuel injectors, for example, in internal combustion engines (ICEs), in the boilers.
The closest device for the same purpose to the claimed utility model, a set of attributes is a device preparing a fuel mixture containing the fuel injector prototype (Great Encyclopedic Dictionary, M, 1991, v.2, s.568).
With all the advantages of the prototype, it should be noted that modern devices cooking fuel mixture using fuel injectors, while not perfect and do not provide sufficient homogenization of the fuel mixture, particularly with a deficit of oxidant, such as fuel injection nozzles in heat engines, which leads to excessive fuel consumption, and required to obtain a sufficient degree of purification of exhaust gases of heat engines use additional expensive and unreliable cell toxicity catalysts.
The invention aims to improve the quality of the fuel mixture preparation device, by improving the fuel injector.
The technical result of this utility model is to improve fuel mixture preparation device, particularly in the modernization of the injector by improving the degree of atomization of fuel and, consequently, improving the overall fuel efficiency of the thermal plant and ecological purity of the flue gases.
Said technical result is achieved by that in a device comprising, the device comprising a fuel supply (fuel injector) and oxidant mixing device and fuel and oxidizer fuel mixture supply device into the combustion zone, the fuel introduced electrostatic sprayer.
Fig. 1
Fig. 1 shows a cooking device of the fuel mixture by the example of the injection engine of internal combustion engine.
Fuel mixture preparation apparatus comprises a fuel tank (not shown) of the fuel pump 1, the high pressure fuel line connected through fuel injector 2 to 3 (engine injector). It shows a simplified and consists of a housing 4 having a fuel channel 5 and the nozzle 6. 3 is placed on the nozzle ring 7 electrically insulating paste, and it reinforced annular electrically conductive electrode 8, with an inner bore diameter greater than the diameter of the nozzle 6. The apparatus introduced vortex mixer 9 having a tangential entry into the mixer, such as one or more openings in the housing (only one such opening) to intensive turbulent mixing air-fuel mixture, namely air, exhaust hot engine gases and steam inside this vortex mixer 9 with poleduschey tangensalno feeding them into a conical tube 11 in the vortex swirl zone main oxidant flow - air. Vortex mixer 9 is connected to a tapered pipe 11 with the inlet 13 of the working cylinder of the engine combustion chamber 14 shown simplified. In the combustion chamber of the engine 14 and placed nominal electric spark plug 15 comprising a central electrode 16, electrical insulator 17 and body portion 18 with screw-side electrode 19 and electrically connected to the engine weight. Electrodes 16, 19 and the electrodes of the spark plug 8, the electrostatic atomizer 16 are connected respectively to the fuel source 20 and 21 constant sign pulse voltage to the high voltage power source, such as a battery 22. The figure shows the simplified and the exhaust manifold 23 of the engine, fuel electrostatic spraying zone 24, zone of intensive turbulent mixing of fuel and oxidizer 26, the fuel component 25 and the ignition.
PRINCIPLE OF THE UNIT
When supplying fuel to the fuel injector 3 and the high-voltage pulses to the ring electrode 9, synchronized with pulses of the ignition fuel assembly on the plug 15, the fuel from the nozzle exit 8 subtly and intensively sprayed by Coulomb forces of repulsion due to electrostatic charging of the jet fuel electric charge of the same name plate and simultaneously activated in an electrostatic field. Simultaneously 9 vortexed fuel spray area occurs itensivnoe vortex mixing of the components of the fuel mixture. The air coming from the air filter in a conical swirler 11 vortex mixer 9 intensively twisted while in the vortex nozzle 1 placed in the inlet pipe 8 and fixed pad 9, further swirled air 23, mixing zone intensively mixed with fuel sprayed injection nozzle 3 and further through the conical nozzle 11, 12 activated, a well mixed fuel assembly through the inlet 13 at an elevated inlet valve (not shown) is inside the combustion chamber 14 of the cylinder of the engine, namely in a zone 26 concentration and an ignition fuel assemblies, since the central electrode serves second the potential of the block 20, opposite with respect to the electric potential, which is charged on the fuel nozzle exit 8.
Due to the atomization of fuel by the electric field and vortex mixing FAs FA quality in the zone 25 is much higher than in analog.
As a result, provided an increased degree of dispersion of fuel spray, the homogeneity of the fuel mixture, the internal combustion engine increases fuel efficiency and improving its completeness of combustion, i.e. improving ecology engine.
