Embodiment
Referring to Fig. 1, liquefied petroleum gas container 12 is fed to operation circuit 16 with liquefied petroleum gas (LPG) via container lock 14 and is fed on the in-line filter 4.Then, the liquefied petroleum gas (LPG) after the filtration is sent to allocation block 38 by operation circuit 37.Petroleum gas liquid after the liquefaction flows through heat insulation transmission line 39 to case of sprayer 3 (being presented at Fig. 4 in more detail) from allocation block 38.
Referring to Fig. 2, enter housing 3 from the petroleum gas after the liquefaction of circuit 39, this describes in detail with reference to Fig. 4.Housing 3 has the liquid ejector 20 that is used for LPG supply is arrived motor E.
Use the liquid in the sparger 20 and be fed to the pulse width of sparger 20 from ECU 70, the liquefied petroleum gas (LPG) after the liquefaction is advanced by sparger 20 and is ejected to (see figure 3) in the manifold 32, and should spray directly towards ingress port 29 (see figure 3)s.The injection of the petroleum gas after the liquefaction is by ECU 70 set times, (see figure 3) before making pulsing (see figure 3) and inlet valve 132 being closed after escape cock 133 cuts out, thereby the downward action (see figure 3) of piston 131 can enter motor E, and the petroleum gas after all liquefaction is ejected, and does not leak by escape cock 133.
In the housing 3 do not enter sparger 20 and can be steam state or liquid liquefaction after gas, leave housing 3 by pipeline 240.Pipeline 240 passes bleed gas heater 250.Bleed gas heater 250 has inlet 251a and outlet 252a, inlet 251a and outlet 252a can be connected in the engine cooling waterpipe, so that temperature is about 70 ℃ engine cooling water by heater 250, thereby heat is fed to heater 250, particularly heat is fed to the part of pipeline 240 in heater 250 inside.Like this, any liquid gas by pipeline 240 all is heated also thereby is converted into steam state (if not the words that are in steam state).Pipeline 240 is connected to bleed injector 260, and sparger 260 is designed to spray gas rather than liquid, and sparger 260 sprays steam into inlet manifold 32, as shown in Figure 2.Bleed injector 260 is subjected to ECU 70 controls via the pulse that receives on the circuit 253.Be similar to the pulse on the circuit 86, the time set of the pulse on the circuit 253 makes sparger 260 open when closing with escape cock 133 at inlet valve 132 and activates, so that the liquefied petroleum gas (LPG) of steam state together is supplied to motor E with liquid from sparger 20 ejections.Like this, the identical mode of steam supply employing and liquid supply is controlled, thereby prevents or at least significantly reduce the spill and leakage (blow-through) of steam by motor.The length of the pulse of supply makes the gas flow of wishing be injected in the motor on the size of sparger 260 and the circuit 253, thereby injection can not affected adversely, simultaneously, the cooling effect that is provided by the path through inlet 11, housing 203 and pipeline 240 of liquid gas can not have a negative impact to the cooling of sparger 20.
Bleed gas heater 250 guarantees not have liquid liquid gas to arrive bleed injector 260, because this will change mixture because of the fuel density difference between the liquefied petroleum gas (LPG) of liquid and steam state.
By the heat of bleed gas heater 250 supply preferably the sufficient to guarantee temperature be higher than the steam point of liquefied petroleum gas (LPG) and relatively stable fully.
Fig. 2 and Fig. 3 also illustrate diesel injection device 171, are used for diesel fuel is arrived with the LPG supply via sparger 20 and sparger 260 supplies simultaneously the cylinder of motor E.Like this, by the fuel of supply from the form of liquid petroleum gas of sparger 20 and 260, required diesel fuel amount can be reduced, thereby situation about comparing when only supplying diesel fuels by diesel injection device 171 improves saving of fuel.Further, be transferred to motor by guaranteeing in housing 203 to become the liquid gas that is used for cooling injection device 20 that bubble overflows to close when opening once more with vapor form with inlet valve 132 at the escape cock 133 of engine cycles process, can guarantee that thereby fuel is effectively used increase power, this means does not need very big choke pressure, thereby further reduces firing rate.Fuel supplying also prevents spill and leakage by this way, and this spill and leakage is not only wasted fuel, and can make discharging significantly increase to undesirable level.
Fig. 4 illustrates the details of housing 3.As shown in Figure 4, housing 3 employings are by the form of the piece 300 that forms such as metals such as aluminium.Piece 300 has the lpg inlet 301 of reception from liquefied petroleum gas (LPG) (lpg) fuel of circuit 39.Inlet 301 links to each other with storage 380.
By passing the major diameter thorax hole that end face 309 forms, in piece 300, also form injector chambers 310.Storage 380 has the outlet 311 of the injector chambers of passing to 310 bottoms.Injector chambers 310 has from the chamber path 312 that 310 top extends to dispatch tube 315.Dispatch tube 315 links to each other with steam jet ejector 313, and steam jet ejector 313 is located in the thorax hole 320 that forms in the piece 300.Steam jet ejector 313 is formed for regulating the regulator of the pressure of liquefied petroleum gas (LPG) in the chamber 310 and/or steam, this regulator makes sparger 20 keep cooling, and make the liquefied petroleum gas (LPG) in the chamber 310 keep cooling then, thereby described liquid can not form bubble or evaporation and remain liquid state thus in sparger 20, to be ejected to motor E by liquid ejector 20.
Because the pressure in the chamber 310 is kept by the regulator injector 313 that adopts the steam jet ejector form, therefore,, when descending, pressure can not freeze even when in LP gas fuel, having too much water yet.Therefore, the LP gas fuel proper flow flow to outlet 317 to sparger 20 and from path 312, with desirable pressure in the holding chamber 310, and keeps the liquefied petroleum gas (LPG) in the sparger 20 to be in liquid phase, to spray from sparger.Sparger 313 has outlet 314, the first outlet thorax holes 315 that supply fuel to the first outlet thorax hole 315 and forms expansion chambers and combine with the labyrinth path 316 that passes piece 300.Labyrinth path 316 with combine referring to figs. 1 through the described outlet 317 that is connected to pipeline 240 of Fig. 3.
The various piece 380,315 of described path and 316 forms by boring the thorax hole and block this thorax hole with the pin (not shown) where necessary in piece, perhaps by formation thorax hole in the surface of piece 300, seal this surface with the cover plate (not shown) then and form.The cover plate (not shown) also can be used for Closed End 309 so that sparger 20 securely is positioned in the chamber 310.
Liquefied petroleum gas (LPG) 301 is transferred in the chamber 310 by entering the mouth.This liquefied petroleum gas (LPG) is in high pressure.Sparger 20 is arranged in chamber 310, and is the sparger of market circulation, and it comprises a plurality of inlet openings 330 around its periphery.Hole 330 is arranged to outlet 311 rough alignment that make itself and storage 380, makes liquid liquefied petroleum gas (LPG) can enter in the hole 330 of below, with from sparger 20 ejections.Signal is supplied to the terminal 20a of sparger 20 with operation sparger 20 from ECU 70.
Near outlet 311 and be converted into any liquefied petroleum gas (LPG) of steam state or bubble in the chamber 310 and will be roughly flow and flow to towards the top in chamber 310 and export in the thorax hole 312 around sparger 20.Sparger 20 is provided with around the hole 330 screen covering (not shown), and this also helps bubble and moves and do not enter in the hole 330 around the periphery of sparger 20.Like this, the fuel that enters sparger 20 is in liquid preparing against and sprays, rather than steam or bubble, if described steam that may form or bubble enter the operation that sparger 20 will hinder sparger 20.Outlet thorax hole 312 is communicated with regulator injector 313 with the pressure in the holding chamber 310.Yet, when the pressure in chamber 310 and the thorax hole 312 raises, by to terminal 391 regulator injector 313 being opened signal provision, make the liquefied petroleum gas (LPG) that is in steam or bubble state can pass through regulator injector 313, to be ejected to exit passageway 315 from regulator injector 313, to pass through labyrinth 316 to exit passageway 317, more then to heater 250 then, thereby be fed to motor with steam state, as preceding referring to figs. 1 through as described in Fig. 3.
Regulator 313 thereby be used for the high-pressure area of holding chamber 310, this high-pressure area connects back container 12 by inlet 301.Like this, the pressure in regulator 313 holding chambers 310 approaches supply container pressure as far as possible.This helps making liquefied petroleum gas (LPG) mainly to remain liquid state, to be sprayed by sparger 20.This with piece 300 by liquefied petroleum gas (LPG) from entering the mouth 301 to outlet 317 coolings, be used for minimizing the boiling of the liquefied petroleum gas (LPG) of piece 300, thereby can not hinder liquefied petroleum gas (LPG) to arrive flowing of sparger 20 and from the ejection of sparger 20.Yet, as previously mentioned, to flow to path 312 around sparger 20 by any bubble due to the boiling of liquefied petroleum gas (LPG) or steam, and by the increase of the pressure due to this vaporization regulator 313 will be opened to allow gentle bubble mixt of steam and excessive pressure to release by regulator 313, be closed up to pressure reduction and regulator 313.
At the pressure in regulator 313 downstream sides significantly less than the pressure in the chamber 310, and regulator 313 also keeps the environment under low pressure in downstream side, and making can the vaporization fully owing to the relatively low pressure environment of comparing at the pressure environment with in the chamber 310 in regulator 313 downstream sides by any liquefied petroleum gas (LPG) of regulator 313.Liquefied petroleum gas (LPG) helps cooling block 300 by exporting 317 path and vaporization thereof, thereby makes the liquefied petroleum gas (LPG) of regulator 313 upstream sides mainly remain liquid state as previously mentioned.
As described in referring to figs. 1 through Fig. 3, steam is fed to heater 250 by pipeline 240, and owing to the heat that is supplied to liquefied petroleum gas (LPG) by heater 250, any liquefied petroleum gas (LPG) that is not in steam state as yet will be vaporized.The liquefied petroleum gas (LPG) that is in steam state is supplied to bleed injector 260 then, in the inlet manifold that is introduced into motor E.
Regulator 313 is operated by signal being put on terminal 391, as previously mentioned.These signals can obtain from ECU 70 according to compiling the fuel mapping scheme (mapping plan) to the ECU 70, and described fuel mapping scheme also is used to start sparger 20 liquid gas fuel is transferred to motor E.
Yet, in other embodiments, regulator 313 can be opened and closed by electrical signal, described electric response is supplied by the pressure measuring value of the acquisition of the pressure transducer (not shown) in the chamber 310, make that when pressure reaches predeterminated level sparger 20 is opened, is closed then to allow fuel to leave regulator 313 and lead to piece 250.
