Abstract
The device that is used for steam ejection liquefaction petroleum gas, it comprises the sparger that is arranged on suction tude one end and is positioned at the closure upstream.The other end in suction tude is provided with heating equipment, thereby the liquid knockout that sprays from sparger is on described heating equipment.
Description
The present invention relates to be used for the device of injecting LPG in liquefied condition, it comprises and is arranged on suction tude one end and away from the sparger of closure, and the heating equipment that is arranged on the suction tude the other end, strikes on the heating equipment from the flow of liquid of sparger ejection.
U.S. Pat-A-4 disclosed this device in 378, No. 001.Device shown in its figure is through being designed for injected petrol especially.Though this device effect when using gasoline is fine, yet experiment shows that if use other liquid, during such as liquefied petroleum gas (LPG), its effect is undesirable.Experiment shows that also this device can not make liquefied petroleum gas (LPG) and air mix fully.When injected petrol, can liquid be atomized to eliminate the problems referred to above more satisfactoryly by ejecting more sparse liquid.Yet when steam ejection liquefaction petroleum gas, can not do like this, thereby because this can increase the danger of the shower nozzle that freezes the obstruction sparger.The heat that is absorbed during with fuel evaporation is compared, and liquefied petroleum gas (LPG) is much bigger from the heat that is absorbed on every side when gasification.Owing to this reason, must heat in case nozzle freezes sparger, or in each stroke, spray denser liquefied petroleum gas (LPG) from sparger.Though a kind of method in back is more desirable, yet as mentioned above, can go wrong again aspect liquefied petroleum gas (LPG) and the Air mixing.
Purpose of the present invention will be eliminated this defective exactly.
According to the present invention, above-mentioned purpose can be achieved by following measure, and promptly along the direction of inlet stream, the two all is arranged on the upstream side of closure with injection apparatus and heating equipment.The liquid that is sprayed can be liquefied petroleum gas (LPG).
By heating equipment, can make a part of gasifying liquefied petroleum gas at least, so just can guarantee not have basically aqueous liquefied petroleum gas (LPG) to arrive closure.This point is very important, because the moisture otherwise in air and/or the hydrate can freeze on closure, thereby influences its performance.Because the effect of closure can produce eddy current, thereby liquefied petroleum gas (LPG) is further mixed with air in air-fuel gas mixture.The gasification problem of liquefied petroleum gas (LPG) is different from the gasification problem of gasoline.If gasoline is not gasified totally, oil droplet will appear in inlet manifold, and this does not only produce satisfied mixture, and does not influence the performance of closure, and liquefied petroleum gas (LPG) is quite different, stops up closure thereby it may freeze when gasification.
U. S. Patent 2,644, the accelerator device that discloses a kind of more complicated No. 676 by the control of pin one telescoping valve, relatively moves these parts and a bigger or less opening will occur, and aqueous liquefied petroleum gas (LPG) can be overflowed by this opening.Round this pin one telescoping valve one hot air flow is arranged, it gasifies the liquid that overflows in the sparger rapidly.In addition to the heating of pin one sleeve assembly, with anti-freeze.If to the heating of pin one sleeve assembly, the two moisture that will be condensed is not sticked together.The liquid gas that overflows from the opening between sleeve and the pin is gasified rapidly, does not so just have liquid gas to strike on the facing surfaces.
In addition from GB-A-1,389, No. 839 gas feeding systems that are arranged in the vaporizer first throttle member as can be known.Wherein a sleeve is cut oblique pin and is moved relative to heated, makes that the gas flow that overflows from the circular opening that is defined by sleeve and pin is variable.In this embodiment, because otherwise, the phenomenon of freezing can appear in the gas that sprays from opening, and the result causes pin and sleeve to be sticked together.Will as above-mentioned U. S. Patent is described, be gasified immediately if liquid gas one leaves this circular opening, just do not had the other end that any aqueous liquid gas arrives suction tude.In above-mentioned patent, neither one can accomplish be covered with aqueous liquefied petroleum gas (LPG) in the entire profile of the suction tude of inlet manifold.
According to most preferred embodiment, along gas flow direction, also be provided with heating equipment, so that the fuel that sprays into is done the heating of the optimum state in the throttle downstream.Injection apparatus and heating equipment preferably are configured as one.For the heat that prevents heating equipment is transmitted to injection apparatus,, between injection apparatus and heating equipment, be provided with thermal insulation barriers according to another most preferred embodiment of the present invention.If heat passes to injection apparatus, will in liquid gas, produce bubble, thereby proper dosage is sprayed in influence.
Heating equipment can utilize the heat of engine coolant, on this external heat transfer temperature controlling device can be set.
With reference to illustrated embodiment, present invention is described for example below.The part-structure of close air-intake of combustion engine menifold inlet end schematically is shown with the form of analysing and observe among the figure.
Only show the inlet manifold 1 of motor among the figure.Suction tude 2 links to each other with inlet manifold 1, and pipe 2 comprises a closure 3.2 of suction tude partly illustrate, and the device or an air-strainer of an introducing gasoline can be set in pipeline 4 downstreams.In suction tude 2, be provided with two spargers 5 that are used to spray aqueous liquefied petroleum gas (LPG).For making these gases be in liquid condition, they must be sent into by pipeline 6 under very big pressure.Also be provided with the valve (figure does not show) that is used for sparger 5.Sparger 5 is located in the housing 7, also is provided with heat insulation loop 8 and ring-type hydroecium 9 in the housing 7.Hydroecium 9 links to each other with 11 with connecting line 10, and these pipelines are communicated with the cooling circuit of internal-combustion engine.The pipeline 12 that links to each other with pipeline 10 includes a thermostat 14.Closure 3 is located at housing 7 belows, and below closure 3, also be provided with a ring-type water jacket 15, water jacket 15 links to each other with 17 with pipeline 16.
To the function of said apparatus be described below:
(figure does not show) sprays into one dense aqueous liquefied petroleum gas (LPG) by sparger 5 in suction tude in the internal combustion engine process.Because pressure reduces, liquefied petroleum gas (LPG) will gasify.In gasification, absorb a large amount of heat from the wall of the air that enters and suction tude 2.Absorbed heat is too big so that airborne moisture condensation becomes water droplet.These water droplets can be on the walls of suction tude and are frozen near the closure place, like this will influence the operation of motor and might freeze and stop up closure.For preventing the generation of this phenomenon, according to the present invention, heating equipment is set on suction tude, such as ring-type hydroecium 9.The liquid gas of ejection strikes on the wall near the suction tude of ring-type hydroecium 9 from sparger 5.Therefore this wall does not have the phenomenon of freezing and takes place owing to the heat that has absorbed from the engine cooling circuit heats up.Sparger 5 avoids producing bubble in sparger or other phenomenon that influences ejector function takes place in case the heat in the stop ring shape hydroecium 9 passes to thereby heat insulation loop 8 is set.For the temperature that makes the ring-type hydroecium keeps constant substantially, also be provided with a thermostat 14.
Below ring-type hydroecium 9, also be provided with a ring-type water jacket 15.Its effect is in the closure downstream air-fuel gas mixture further to be heated.Ring-type water jacket 15 also can have a constant temperature device.
Only most preferred embodiment of the present invention is described with reference to accompanying drawing above, yet should be understood that for the person of ordinary skill of the art, under the condition that does not deviate from spirit of the present invention, also can make some conversion, can adopt electric heater such as heating equipment to the present invention.
