Description

Motor

The present invention relates to a kind of motor, vehicular engine especially, it is by gas compressor, the firing chamber, compositions such as active force combustion gas motor and auxiliary device can use various gas, and liquid or gas-liquid mix fuel.

The vehicular engine that uses has reciprocating piston type at present, and triangle piston is rotary, gas turbine etc.Reciprocating piston type development is very ripe but its basic scheme has basic weakness, and it has many reciprocating mass, as piston port mechanism etc., has hindered the further raising of rotating speed; Combustion intermittence not exclusively, pollutes big; Require high to fuel oil.Though the wankel triangular piston rotary engine that occurred in 50 years has been realized no complicated to-and-fro motion part, its firing chamber is long and narrow, and fuel economy is relatively poor; Low-speed dynamic, startability are also bad.Gas turbine has higher power to weight ratio, stable working, but because cooling problem cost of material is too high, and compression ratio is lower, and Economy is not good, can't promote at automobile-used low power range.

In addition, conventional engine moment of torsion commonly used is not substantially with rotation speed change, and therefore power, will often change shelves to guarantee vehicle dynamic quality with the rotating speed rapid change in the vehicle driving process.

The object of the invention provides a kind of motor that rotor internal combustion engine and gas turbine are combined, and it does not have complicated reciprocator, and running steadily realizes continuous burning, and it is approximate constant power in big speed range.

The present invention realizes its purpose like this:

Theoretical thermodynamics circulation of the present invention is the Brayton circulation.Its process: 1. working medium (fresh air) adiabatic compression in gas compressor; 2. working medium isobaric heating in the firing chamber; 3. working medium (combustion gas) adiabatic expansion in active force combustion gas motor, externally acting; 4. the isobaric heat release (waste gas enters atmosphere) of working medium.Motor is by gas compressor, active force combustion gas motor, and firing chamber and auxiliary feed-oil, lubricated, starting cooling waits device to form, use gas, liquid or gas-liquid mixed fuel.Gas compressor is made up of the power section and the part of calming the anger, and power section is promoted by combustion gas, drives the part of calming the anger and infeeds the firing chamber with the fresh air suction and after compressing.The firing chamber inwall has air supply opening, jet, and igniter has two gas outlets, and one leads to the active force motor another leads to gas compressor.Active force combustion gas motor is a rotator type, in the rotor rotation process, and the swept volume that rotor and shell formation cycle change.A swept volume hour high-temperature high-pressure fuel gas charges into, and along with the rotor rotation, volume increases gradually, and combustion gas is done work to rotor; When swept volume reached maximum value, the exhaust port that has on the shell was the combustion gas row atmosphere after expanding.Gas compressor power separates with the active force motor.The firing chamber leads on the combustion gas road of gas compressor has two throttle valve, self-acting valve and throttle valve.Self-acting valve changes with combustion chamber pressure regulates the ventilating hole size automatically, and it is young to ventilate when pressure is big, and pressure hour ventilating hole is big, to guarantee throttle valve one regularly, under the combustion chamber pressure different situations, certain substantially to the power of gas compressor acting by the combustion gas of self-acting valve.The throttle valve is controlled by the people, regulates compressor power, with the adjusting air inflow, and the oil transportation amount, thus regulate whole engine power.Fuel pump power is provided by gas compressor, and pump power is directly proportional with compressor power, and oil transportation amount and air delivery volume remain near the optimum ratio.

Gas compressor is equivalent to the combination of combustion gas motor and air pump, gas compressor can drive centrifugal-flow compressor with the turbine that low merit power gas turbine is used, and also can use the rotor pump of the swept volume cycle variation of the rotor combustion gas motor drive that is changed by the swept volume cycle.

The similar low-power gas-turbine combustion chamber in firing chamber, but it has the ignition mechanism of band pressure transducer, and two gas outlets are arranged.

Active force combustion gas motor is by shell, compositions such as rotor.Rotor is made up of rotating shaft and loose-leaf.Shell is a nearly cylindroid shell, and its inwall path is identical with rotor diameter.Rotating shaft is essentially an oblate post, has the axis hole that is hinged with loose-leaf near its circumference, has on the relevant position and can hold the groove position that loose-leaf is taken in rotating shaft fully.When loose-leaf was taken in rotating shaft fully, rotor constituted a complete cylinder.Anduo County's loose-leaf in the rotating shaft.The loose-leaf part can have multiple shape, and it is hinged in the rotating shaft, and under centrifugal force and gas pressure effect, opened with certain angle is touched mutually with outer casing inner wall, loose-leaf radially, end face, the rotating shaft end face, hinged place, and rotating shaft, all there is Stamping Steel Ribbon at the tangent place of shell.In rotating shaft, loose-leaf forms the seal operation chamber between shell like this, and this Seal cage will be cyclically-varying with the rotor rotation.On shell, have fuel gas inlet and outlet.Along with working chamber volume increases to maximum by zero, high-temperature fuel gas enters active chamber and finishes the acting of expanding; Reduce to zero process from maximum, waste gas is discharged.

When the motor desire was stopped working, the family of power and influence closed with engine oil, and the mouth of gas compressor power partial-air admission simultaneously is communicated with atmosphere.During starting, actuating motor drives gas compressor and is pressed into air, infeeds oil inflame chamber pressure one regularly, the igniter igniting, and the throttle valve is opened engine start simultaneously.

The present invention has following advantage:

1. because gas compressor and oil pump power are relatively independent of the active force motor,, make motor, make automobile reduce speed change gear, handiness near the constant power ideal engine so in big speed range, can provide same amount air feed and fuel feeding.

2. realize the fuel oil continuous burning, the fuel-air mixture example is best, and burning is complete, and good economy performance is polluted little.

3. there is not complicated reciprocator, symmetry simple in structure, running is steady, the rotating speed height.

4. starting only needs to drive gas compressor, and starting torque is little, and starting speed is low, and starting performance is good.

5. low to demanded fuel, can use various gas-liquids or gas-liquid to mix fuel.No phenomenon of detonation, the compression ratio height.

Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.

As Fig. 1,2,3, during engine start, drive gas compressor 7 rotary works by actuating motor 10, fresh air is pressed into firing chamber 1 by suction port 8, gas compressor drives fuel pump 9 work fuel oil is infeeded firing chamber 1 simultaneously.When pressure reached certain setting value in the firing chamber 1, the igniter igniting produced high-temperature high-pressure fuel gas in the firing chamber 1, and starter motor 10 breaks away from gas compressor 7 simultaneously, and throttle valve 3 is opened, and high-temperature high-pressure fuel gas is divided into two-way.One the tunnel enters gas compressor power part through self-acting valve 2 and throttle valve 3, promotes gas compressor work.Because self-acting valve 2 effect, make that compressor power keeps constant when throttle valve 3 is constant, thereby the air feed fuel delivery is constant, it is constant that engine power keeps.The people controls throttle valve 3 with control complete machine power.Another road combustion gas enters active force combustion gas motor 4, promotes its rotation, by main shaft 5 external output powers.The combustion gas expansion is after outlet pipe 6 enters atmosphere.

As Fig. 4 is 4 one embodiments of active force combustion gas motor.Loose-leaf 17 is the circular arc thick plate-like, have 12 pages, its vertical major direction cross section excircle curvature is consistent with rotating shaft 20 outer diameter curvature, and loose-leaf is hinged in the rotating shaft 20 by pin 18, and can open the swept volume of several angle and the 12 formation volume cycles variations of rotating shaft 20 shells.Rotating shaft 20 has Stamping Steel Ribbon 11 with shell 12 tangent places, and rotating shaft 20 end faces have Stamping Steel Ribbon 13, and loose-leaf 17 end faces have diaphragm seal 14 and Stamping Steel Ribbon 15, and Stamping Steel Ribbon 19 is radially arranged, and also there is Stamping Steel Ribbon loose-leaf and rotating shaft hinged place.High-temperature high-pressure fuel gas enters rotor motor by fuel gas inlet 21, and along with the rotor rotation, swept volume increases gradually, and combustion gas is expanded to the loose-leaf work done.Two adjacent active chamber air pressure differences in inflation process, loose-leaf relies on centrifugal force and two active chamber pressure differences, and is pressed on shell 12 inwalls, realizes sealing.When swept volume reached maximum, the combustion gas after will expanding by relief opening 16 was discharged.Loose-leaf can be made with the high temperature resistant inorganic nonmetallic material.

As Fig. 5,6, be an embodiment of gas compressor 7.Its structure is equivalent to the connecting shaft combination of two above-mentioned active force combustion gas motor configurations.Power section is one is just changeing the combustion gas motor, and the part of calming the anger is the combustion gas motor configuration of counter-rotating, and combustion gas enters power section by inlet 23, promote loose-leaf 22 and make power shaft 4 rotations, combustion gas is discharged by relief opening 29, and power shaft 25 joins with the rotating shaft 26 of calming the anger, and drives rotating shaft 26 rotations of calming the anger.26 formation cycles of adjacent two pages of loose-leaves 27 of the part of calming the anger and shell and rotating shaft change swept volume.It sucks fresh airs from air inlet 28, this moment the swept volume maximum, along with the rotating shaft rotation, swept volume is dwindled gradually, air pressure increases, and is pressed into the firing chamber by gas outlet 24.Its axial length of the part of taking offence slightly is longer than the part of calming the anger, and is slightly larger than the part of calming the anger to guarantee power section power, guarantees the unidirectional rotation of gas compressor, and oil pump power is provided.

As Fig. 7 is an embodiment of gas compressor.Its structure and existing wankel triangle piston circulating engine are similar.Cylinder inner wall is the short circle of the two arc length of " a 8 " font inner rotary line, but its piston 34 outer arced surface are complete arc column face, do not have indent.Have relief opening 31 and suction port 32 in cylinder inner wall one side, opposite side has fuel gas inlet 39 and compressed air outlet 36, and valve 38 and valve 37 are arranged respectively on it.There is Stamping Steel Ribbon 35 at cylinder 30 inwalls " 8 " font middle part.Left-half is a gas compressor power part, and right half part is the part of calming the anger.Power section: high-temperature high-pressure fuel gas is infeeded by fuel gas inlet 39, and swept volume is by the zero small volume process that increases to a setting, and valve 9 is opened, and combustion gas charges into swept volume; Valve 38 is closed then, and swept volume increases to maximum volume by setting small volume, and the acting of gas adiabatic expansion promotes piston 34 rotations.The back gas that expands is discharged by relief opening 31.The part of calming the anger: fresh air is entered by suction port 32, when the part swept volume of calming the anger is maximum, and inlet close.Swept volume reduces gradually with piston 34 rotation, and gas pressure intensity increases, and when pressure during greater than combustion chamber pressure, valve 37 is opened, and pressurized air infeeds the firing chamber.Stamping Steel Ribbon 35 is separated power section and pressure portion, in case collaborate mutually.

Be firing chamber and self-acting valve among the present invention, throttle valve view as Fig. 8.Fuel oil is infeeded by transport pipe 40, and pressurized air is infeeded by gas circuit 41, and 42 is the ignition mechanism of belt sensor, and 1 is the firing chamber main body.High-temperature high-pressure fuel gas one tunnel infeeds active force combustion gas motor through active force combustion gas road 44, and another road infeeds gas compressor power part through gas compressor combustion gas road 43.On gas compressor combustion gas road, self-acting valve 2 is arranged, to guarantee that at throttle valve 3 one regularly it is certain to supply with the gas compressor gas horsepower.Self-acting valve 2 connects rod-like element for spring.When pressure in the firing chamber increased, self-acting valve 2 was depressed, and gas compressor combustion gas path is narrowed down; Otherwise self-acting valve 2 is ejected by spring 45 the combustion gas path is broadened.Throttle valve 3 is the artificial mechanism that regulates complete machine power, regulates compressor power by regulating throttle valve 3, thereby regulates the air feed fuel delivery.

The engine misses process: the throttle valve cuts out, and the free vent that is equipped with on gas compressor combustion gas road is simultaneously opened, and closes oil pump simultaneously, at this moment owing to chamber pressure and oil pump resistance, and the rapid stall of gas compressor, complete machine stall.

During starting, the throttle valve cuts out, and gas compressor power part free vent is opened.Starter belt dynamic pressure mechanism of qi is calmed the anger to the firing chamber, drives oil pump simultaneously and infeeds fuel oil, when chamber pressure is enough, pressure transducer makes the igniter igniting, and step on the throttle this moment, promptly opens the throttle valve, gas compressor power part free vent is closed, and starter motor breaks away from gas compressor, engine start work.

Other auxiliary device of motor and prior art are approaching.
