Now, be used for will exemplarily being described with reference to the drawings with partly melting two examples of air jet to the injection apparatus of cryogenic engine, wherein:
Embodiment
Each example design of injection apparatus is ejected into the working room of cryogenic engine for the charging that will partly melt air, and cryogenic engine is preferably disclosed cryogenic engine in PCT specification WO01/63099, and the disclosure is as with reference to introducing.Partly melting air is liquefied air and curing AIR MIXTURES, and liquid state-solid-state ratio is 60:40, thereby mixture has enough fluids to spray.In the working room of motor, partly melt air from the heat exchanger fluid received energy and the generation engine shaft power that expands.
The injection apparatus of Fig. 1 to 3 comprises the injection member of plunger 4 forms, plunger 4 in cylindrical housings 6 back and forth and with its sealing engagement.Housing 6 has first area 8 (be in double and melt the enough low temperature of air) and is in the second area 10 of environment temperature, usually between 10 ℃ and 20 ℃.The wall of housing has the increase diameter parts that forms the annular entrance chamber, and plunger has the minimizing diameter parts that forms the waist shape zone that limits annular volume.
Plunger 4 experience injection and return stroke alternately is partly to melt air 2 and it is flowed to the working room of cryogenic engine under pressure from its source with the low pressure absorption.
For this reason, low pressure is partly melted air source and is set to be communicated with the annular entrance chamber.When injection stroke begins (Fig. 1), the waist shape regional connectivity in annular entrance chamber and the plunger, thereby annular volume be full of low pressure partly melt air 2.Plunger 4 moves down in housing 6 then, with experience injection stroke (Fig. 2), and plunger and shell body wall sealing engagement, thus the air 2 that partly melts of this volume in the chamber carries to zone 10 from zone 8 with plunger 4.In case reach zone 10, transmission in a small amount partly melt air boiling because its higher temperature of experience in zone 10, thereby produce high-voltage power supply, when the injection stroke that is no longer covered by shell body wall in the chamber finished, this high-voltage power supply drove the dosage in the chamber of cryogenic engine (Fig. 3) that partly melts air.
Referring to Fig. 4 to 7, second embodiment of injection apparatus comprises can be with the reciprocating plunger 20 of certain interval in cylindrical housings 22, has inlet valve 24 and partly melts the introducing of air and outlet valve 26 with control from the low pressure of partly melting air source and partly melt air from housing 22 flowing to the working room of cryogenic engine with the control high pressure.Valve 26 has valve rod 30, and valve rod 30 is by the passage in the plunger 20.
When injection stroke begins (Fig. 4), inlet valve 24 is opened and outlet valve 26 cuts out, and low pressure is partly melted air and entered the first area 32 that is in low temperature in the housing.Inlet valve 24 cuts out and plunger 20 beginning injection stroke then, upwards moves (Fig. 5) towards low-temperature region 32 in housing 22.During the injection stroke of plunger 20, partly melt air and transmit by moving to the second area 34 that is in environment temperature from low-temperature region 32.When injection stroke finishes (Fig. 6), roughly all partly melt air and transmit, and since the higher temperature in the zone 34, the nitrogen boiling of small volume.The high pressure that obtains is opened outlet valve 26, and makes and partly to melt the working room that air under high pressure is ejected into cryogenic engine.
In each embodiment, partly melt air and will remain on first (low temperature) zone with the low temperature of needs by flowing of device.Second (higher temperature) zone is by cylinder or shell heat absorption from cryogenic engine, or contact heat absorption with heat exchanger fluid and remain on need higher temperature.This device drives (for example, from its camshaft) by cryogenic engine, maybe can be from the electrical motor driven of separating.The quantity of partly melting air that enters this device can control (for example, by valve, or passing through the control pump speed relevant with cryogenic engine).
Injection apparatus shown in Fig. 8 and 9 has general cylindrical housing 36, extends 12 heat-exchange tube 38 arrays in the housing 36, such as the heat exchanger fluid 40 of ethylene glycol by heat-exchange tube 38.At the entry zone place of housing, the introducing that air 44 is partly melted in inlet valve 42 control is partly melted air 44 and is supplied to injection apparatus by supply tube 46, be supplied to 46 with keep partly melting air supply and be communicated with in the adiabatic supercharging storage box 47 of approximately bearing 220 ℃.For the sake of clarity, schematically and to reduce ratio show this case.At the exit region of housing, this moment, air flows to two stroke cryogenic engines under pressure cylinder 50 was partly melted in outlet valve 48 control, have can be in cylinder 50 pistons reciprocating 52.
Similarly, outlet valve 48 has removable valve member, and removable valve member has the bar 64 of elongation, and bar 64 ends at the valve head 66 that cooperates with valve seat 68 on the lower end of cylindrical guider 70 in its lower end.Valve member stem 64 is slided in guider 70, and by the internal surface sealing of circumferential seal 72 with respect to guider 70.
Just on valve seat 68, outer pipe 74 is communicated with the lower end of guider 70, feeds in the upper end of cylinder 50.The upper end of cylinder 50 has two valves, promptly is used for heat exchanger fluid 40 is introduced the valve 76 and the valve 78 that is used for discharging by discharge tube 80 heat exchanger fluids and driving fluid of cylinder 50.Cryogenic engine is two-cycle engine and works in disclosed mode among the WO 01/63099.Fig. 8 and 9 injection apparatus and cryogenic engine are operated in the following manner.
Begin (as shown in Figure 8) at top dead center from piston 52, inlet valve 42 cuts out, and outlet valve 48 is opened, and two valves 76 and 78 cut out.Driving fluid (promptly, partly melt air) charging force by the outlet valve 48 opened and enter cylinder 50 from housing 36, wherein driving fluid expands (heat absorption of the heat exchanger fluid from cylinder 50 simultaneously), makes piston 52 experience power strokes to drive crankshaft engine.Finish near power stroke, along with piston 52 approaches bottom dead centre, expulsion valve 78 is opened and outlet valve 48 stays open, up to piston 52 just on lower dead center, the pressure when closing in the housing to reduce outlet valve.During the return stroke of piston 52, outlet valve 48 cuts out, and inlet valve 42 is opened as quickly as possible thereafter.This makes the charging of driving fluid introduce the space of surrounding tube in the housing 36.Give driving fluid by managing 38 heat-exchange fluid 40 with thermal energy transfer, make in a small amount driving fluid boiling, thereby increase the pressure in the housing, therefore when outlet valve 48 was opened when next power stroke begins, driving fluid was ejected into cylinder under pressure.During the return stroke of piston 52, valve 76 is opened heat exchanger fluid is guided into cylinder 50.
Above-mentioned valve timing needs inlet valve 42 to experience operation cycle with outlet valve 48 with the speed identical with cryogenic engine.This proposes sizable requirement to inlet valve 42, and in order to satisfy this problem, injection apparatus can duplicate (or repeating any time).For example, a pair of injection apparatus, each can be arranged side by side to supply single cryogenic engine, so each of these two devices is with half operation of the speed of needs when motor is supplied by single assembly shown in Fig. 8 and 9.
The heat exchanger fluid that is supplied to housing 36 is the liquid identical be supplied to cylinder 50 by inlet valve 76.Be supplied to the liquid of housing 36 to be preferably by branch's link and take out from the main heat exchanger fluid that is supplied to cylinder, the liquid that flows out from housing 36 is supplied after cylinder 50 is discharged and is got back to returning of heat exchanger fluid.Import and outlet valve guider 60 and 70 and bar 54 and 64 extend, thereby Sealing 52,72 can be away from the low-temperature region location of the lower end of these valves.
In the injection apparatus of Figure 10 and 11, the parts identical with 9 parts corresponding to Fig. 8 have identical reference character.Figure 10 and 11 difference are: the mode that supply tube 46 continues by guider 60; On guider 60 lower ends, the interval of the increase of the attachment portion between pipe 46 and the guider 60; Form spring-loaded check valve member 84 to its closed position bias voltage with the inlet valve member, wherein check valve member 84 engages with the lower end of guider 60.Inlet valve 42 is opened by moving down of bar 54, and this not only catches the driving fluid of certain volume in the lower length of guider 60, and impels check valve member 84 to open, thereby the driving fluid of this volume is pressed in the housing 36.
After entering housing 36, partly melt air and receive heat, thereby the fraction boiling will partly be melted air to drive by outlet valve 48 and in cylinder 50 about Fig. 8 and 9 described modes from heat exchanger.
