The present invention is as shown in Figure 3.Arrange wear-resisting cylinder liner in the cylinder horizontal positioned of motor, each cylinder, the intermediate arrangement oil sprayer of cylinder liner simultaneously, has gas port at medium position, and a side is a suction port, and opposite side is a relief opening.Suction port is used in cylinder, carrying fresh air, and relief opening is used for waste gas is discharged through exhaust manifold.Be furnished with the piston of two relative movement in each cylinder sleeve, when approximated position is arrived in two piston motions, form the firing chamber.Rocking arm is arranged in through pitman arm shaft on the hydraulic support frame at two ends of cylinder block; the upper end of rocking arm is connected with piston in the cylinder through small rod; the lower end of rocking arm links to each other with bent axle under being positioned at cylinder block through big connecting rod; rocking arm has designed a hydraulic plunger drive installation position near the rocking arm center, and through 73 hinged, the swing of rocking arm drives hydraulic plunger through the arm between hinged mounting point of hydraulic plunger bulb and the gyration center and in oil hydraulic cylinder 74, does and pump; combine oil sucting one-way valve 7502 and fuel-displaced one-way valve 7501 completion hydraulic oil by the conversion of low pressure to high pressure, the output of realization hydraulic pressure ability.Simultaneously, the to-and-fro motion of opposed pistons under the promotion of fuel combustion energy drives crankshaft rotating through rocking arm, large and small connecting rod in the cylinder, and then output mechanical energy.The to-and-fro motion of piston also combines the gas port position to accomplish ventilatory except that the conversion of accomplishing form of energy.Different definition according to the control gas port is: the piston of control suction port opening and closing is called the air inlet piston, and the piston of control opening and closing relief opening is called exhaust pition.

The double dynamical output motor of this machine-liquid adds the mechanical combined booster of fluid motor-driven; Machinery-turbine the two poles of the earth the pressurized machine that drives simultaneously by oil hydraulic motor and exhaust gas turbine; Be used for realizing that motor provides rational scavenging pressure under various operating modes such as high low speed, high low-load; Through machinery, turbo-driven gas compressor the air of certain pressure is pressed into cylinder; Residual gas in the cleaning cylinder utilizes pressurized machine to improve the air density that gets in the cylinder, reaches the purpose that improves engine output, improves motor Economy and emission performance.

It is that motor provides higher injection pressure that the double dynamical output motor of this machine-liquid adopts the high-pressure common rail fuel oil supply system; High pressure fuel pump passes through crank-driven; For oil sprayer provides high pressure fuel, oil sprayer under the control of electronic controller according to engine operational cycle and ignition order requirement, regularly, quantitatively high pressure fuel is sprayed into cylinder; Two oil sprayers that this motor adopts the cylinder side to be 90 degree layouts are in the cylinder high pressure fuel to be provided; Flow feature in the cylinder that forms in conjunction with the angle of suction port on the cylinder sleeve adopts three hole fuel injector structures to carry out fuel injection, for effectively tissue burning, reduce the oil bundle and be rebuffed, reduce discharging etc. and have positive effect.Simultaneously, adopt the oilhole arranged tangential, in cylinder, spray into fuel oil, can improve the power index of motor significantly.

Be positioned at bent axle under the cylinder block and adopt mistake to turn structure can to realize the asymmetric uniflow scavenging of motor, realize effectively that relief opening is early opened and back scavenge effect that suction port closes evening, improved the scavenging efficiency of double dynamical output motor in conjunction with supercharging technology greatly.Overcome the shortcoming of traditional opposed two-stroke scavenge effect difference effectively.

Be arranged in the opposed pistons reciprocating of two end faces in the same cylinder sleeve 4,4a by the difference of controlling suction port 301, relief opening 302 opening and closing respectively, be called air inlet piston 4 and exhaust pition 4a respectively.Air inlet piston 4 is connected with the microcephaly of last connecting rod through wrist pin 18 respectively with exhaust pition 4a.Last connecting rod 5 major parts are through connnecting rod big end pin 6 and rocking arm upper end hinged 8; mid point of rocking arm 8 is oscillation centers of rocking arm; the lower end of rocking arm 8 is hinged with lower link 11 microcephalies through link pin 17, and the major part of the pairing lower link 11 of intake and exhaust piston is connected on two adjacent crankshaft pins of same bent axle 12 through crank pin respectively.Above-mentioned all through the joint of pin Placement anti-wearing liner or bearing shell are installed all.The firing chamber 2 of motor is made up of at the place, approximated position of piston cylinder sleeve 3 and two opposed piston-top surfaces, and oil sprayer 1 circumferential arrangement is in the cylinder liner side.Intake and exhaust piston 4,4a head adopt the combustion-chamber shape of airflow pattern in coupling oil sprayer and the cylinder, leave the pit that is used to dodge the oil sprayer oil nozzle simultaneously, collide to avoid piston and oil nozzle.

Concrete workflow is following: the piston that mirror image is arranged in the cylinder liner under bent axle drives when the inner dead point direction moves near inner dead point; Two oil sprayers that are arranged in the cylinder sleeve side spray into the firing chamber with high pressure fuel; High pressure fuel atomizing and under high temperature and high pressure environment voluntarily fire burns; The pressurized gas that fuel combustion produces promote piston to the motion of outer dead point direction, and piston drives crankshaft rotating, output mechanical energy through last connecting rod, rocking arm, lower link in outer dead point direction movement process.Simultaneously, the swing of rocking arm drives pumping of hydraulic plunger and realizes the output of hydraulic pressure ability.When outer dead point moved near outer dead point, exhaust pition was at first with Exhaust Open at piston, and exhaust gas inside cylinder is discharged at a high speed under differential pressure action voluntarily; Be called the free exhaust stage, along with piston continues to the motion of outer dead point direction, the air inlet piston is with air inlet open; Fresh air gets into cylinder under the gas compressor effect, the fresh air that gets into cylinder is further released cylinder with the residual gas in the cylinder, gets into scavenging period; Piston motion is crossed outer dead point to the motion of inner dead point direction under crank-driven behind outer dead point, along with the motion of piston to the inner dead point direction, close porting gradually; Because have certain wrong turning degree between the pairing crankshaft crank of intake and exhaust piston, in the inner dead point movement process, relief opening is at first closed at piston; Suction port is closed again afterwards; Realize back inflation effect, improved charging efficiency, realized asymmetric scavenging.After the air inlet piston is with inlet close; Piston gets into the compression gas in the jar stage, and along with piston moves to the inner dead point direction, gas in the jar is compressed thereupon; When piston motion oil sprayer near the inner dead point position time sprays into the firing chamber with high pressure fuel, so circulation realizes that motor moves continuously.

The opposed pistons two stroke engine structure that the present invention designed, the hydraulic plunger structure has the following advantages:

A: two shared cylinder sleeves of piston, reduced heat transfer area in the cylinder, saved baroque cylinder head, reduced the combustor surface thermal loss, simplified engine structure;

B: the opposed piston of mirror image has reduced the side pressure of piston greatly through the transmission of last linkage mechanism realization piston motion and power, has reduced the friction between piston and the cylinder liner, effectively reduces mechanical loss; Simultaneously, piston does relative motion, and inertial force is cancelled out each other, and system's self balancing of realization has reduced body vibration.

C: adopt the two stroke operation principle, bent axle whenever turns around acting once, compares the specific power that has increased motor with four stroke engine;

E: adopt the to-and-fro motion of fork drive hydraulic plunger, saved the swash plate body of conventional post piston hydraulic pump, have advantages such as simple in structure, reliable operation, maintenance, low cost of manufacture.

Engine operational cycle and port timing

The double dynamical output motor of machine-liquid adopts the two stroke diesel engine working principle, and engine crankshaft whenever circles and accomplishes a circulation.

In a bent axle cycle period, the working procedure of the double dynamical output motor of machine-liquid is following:

Expansion stroke: the piston relative movement is during near inner dead point; Oil sprayer sprays into cylinder with high pressure fuel, and fuel oil catches fire under the HTHP effect voluntarily, and the pressurized gas of generation promote piston and move to the outer dead point direction; In this process; Piston is converted into the mechanical energy output of bent axle with the heat energy of fuel combustion, and simultaneously, part energy is converted into the output of high pressure liquid pressure energy through hydraulic plunger.

The free exhaust stage: when piston when outer dead point moves near outer dead point; Exhaust pition is at first with Exhaust Open, and exhaust gas inside cylinder is discharged at a high speed under differential pressure action voluntarily, is called the free exhaust stage; The free exhaust stage continues up to the air inlet piston air inlet open position is finished; At this moment, residual gas pressure reduces greatly in the cylinder, is lower than scavenging pressure.

Scavenging period: along with piston continues to move to the outer dead point direction; The air inlet piston is with air inlet open; At this moment, owing to the free exhaust stage reduces residual gas pressure in the cylinder, along with the unlatching of suction port; Fresh air gets into cylinder under the gas compressor effect; The fresh air that gets into cylinder is further released cylinder with the residual gas in the cylinder, and scavenging process continues up to piston motion and behind outer dead point, under crank-driven, crosses outer dead point to the motion of inner dead point direction, till with exhaust close.

The back charging stage: along with the motion of piston, close porting gradually, owing to have certain wrong turning degree between the pairing crankshaft crank of intake and exhaust piston to the inner dead point direction; At piston in the inner dead point movement process; Relief opening is at first closed, and suction port is closed again afterwards, has realized back inflation effect; Improve charging efficiency, realized asymmetric scavenging.

Compression stroke: after piston was all closed porting, the piston relative movement got into compression stroke, and the gas of sealing up for safekeeping in the compression cylinder finishes up to the inner dead point compression stroke.

Fuel injection: when piston relative movement during near inner dead point, high pressure fuel sprays into cylinder under the oil sprayer effect, and the high pressure fuel that sprays into cylinder compresses in cylinder under the high temperature and high pressure gas effect, further atomizing, evaporation, and then burning.

The port timing of double dynamical output motor involved in the present invention is as shown in Figure 4: inlet and outlet mouth open area that port timing shown in Figure 5 is corresponding and the corresponding relation between the crank angle.

Mistake through bent axle turns structure; Realized the asymmetric scavenging of piston control gas port-gas port uniflow scavenging mode; The present invention adopts relief opening to open in advance, and suction port lags behind to close and realizes sufficient free exhaust and back inflation mode, reaches the effect of optimizing charging efficiency.

Shown in indicator diagram under the port timing condition as shown in Figure 6:

Fresh air charges into cylinder

When piston motion when opening the suction port position, fresh air is pressed into cylinder with air under the effect of gas compressor.

Compression stroke

Compression stroke is meant from piston motion and begins to closing inlet and outlet mouth position, the process of end to piston motion to the inner dead centre position.In compression stroke, piston is closed inlet and outlet mouth continued to inner dead point direction motion, and the fresh air in cylinder is sealed in compression up for safekeeping, makes temperature, the pressure of the fresh air in the cylinder be elevated to be enough to let the state that the fuel that sprays into cylinder catches fire automatically.

Combustion process

Near at the end, a certain moment sprays into cylinder with high pressure fuel through oil sprayer before the internal volume dead point in compression stroke, and high pressure fuel is after getting into cylinder; Process atomization and vaporization in the environment of high temperature, high-pressure air in cylinder; Along with the further completion of compression stroke, a part of fuel oil catches fire voluntarily and takes fire, (among Fig. 6; Take fire at the c point), pressure is being elevated to the z point rapidly.Piston gets into expansion stroke under the promotion of pressurized gas after crossing inner dead point.

Expansion stroke

The characteristics of expansion stroke are that high temperature, the pressurized gas that fuel combustion produces promote piston rapidly to the outer dead point motion, and volume of cylinder increases, at the expansion formation initial stage; The cylinder fuel combustion process is still being carried out, and the chemical energy of fuel oil is transformed into heat energy, along with the carrying out of burning; Exothermic process lasts till that always burning finishes; Make interior gas temperature of cylinder and pressure raise, promote piston and move, after this increase rapidly owing to burning weakens with volume of cylinder gradually to outer dead point; In-cylinder pressure is descended, and the heat energy of combustion gas changes mechanical work in the inflation process.Expansion stroke is until Exhaust Open.

Gas exchange process

A point in inflation process, relief opening is opened., under the effect of residual gas pressure, in cylinder, discharge outside the cylinder with very high speed at gas in the jar through relief opening.Waste gas entering turbo machine under the effect of guide plate of discharging, waste gas continue to expand in turbine, and change it rotation of into mechanical work promotion gas compressor.

The b of a period of time point scavenging port is opened behind the exhaust open mouth; This moment, in-cylinder pressure was lower; Get in advance air compressed and under the effect of pressure reduction, get in the cylinder waste gas is extruded cylinder, waste gas is extruded the process that the cylinder fresh charge gets into cylinder and is called cylinder scavenging.

When outside the piston arrives during volume dead point, expansion stroke finishes, and at this moment the inlet and outlet mouth is opened fully.

The burning of the initial stage of expansion stroke with fuel oil is main, later stage combustion gas and fill with fresh air to cylinder.

The inlet and outlet mouth is in open mode simultaneously when compression stroke begins, and scavenging process is still continuing, and along with piston moves to inner dead centre, relief opening at first is closed, and scavenging process finishes.At this moment, suction port also is not closed, and charge air flow continues to get into cylinder under action of inertia, up to the air inlet piston inlet close is finished, and this process is called the back gas replenishment process.

Can find out from port timing Fig. 4; Gas exchange process involved in the present invention can be divided into three phases; From the Exhaust Open to the scavenging port, open and be called " free exhaust stage "; Scavenging port is opened to exhaust close and is called " scavenging period ", and exhaust close is closed to scavenging port and is called " post-aeration stage ".

Pump oil process

The oil hydraulic pump oil-absorbing process of double dynamical output motor: when moving upward under the drive of hydraulic plunger 73 at fork,, form vacuum in the oil hydraulic cylinder 74, low pressure oil is passed through oil sucting one-way valve 7501 with low pressure oil inhalant liquid cylinder pressure because hydraulic plunger moves upward; When the inner dead point position was arrived in piston motion, corresponding hydraulic plunger moved to top dead center position, and oil-absorbing process finishes.When piston got into expansion stroke, piston drove rocking arm and swings clockwise, and then took hydraulic plunger to and move downward; Because hydraulic plunger moves downward, the hydraulic oil in the oil hydraulic cylinder is compressed, and in line check valve is closed; Hydraulic fluid pressure raises rapidly in the oil hydraulic cylinder, and fuel-displaced one-way valve 7502 is opened, and pressure oil in the oil hydraulic cylinder and high voltage terminal are connected; Move downward in the process at plunger the high pressure oil in the oil hydraulic cylinder is outputed to high voltage terminal, realize that hydraulic pressure can export.This hydraulic pressure can output procedure lasts till always that piston motion arrives outer dead point and finish.So back and forth, hydraulic plunger is realized pumping under the effect of reciprocating motion of the pistons, accomplishes hydraulic oil by the conversion of low pressure to high pressure.

The general structure of the double dynamical output motor of machine-liquid

Fig. 7 is the double dynamical output engine structure of a machine-liquid schematic representation.The cylinder liner horizontal positioned of motor, cylinder liner and piston, connecting rod, swing-bar mechanism constitute a unit, and the mode that a plurality of unit can adopt a plurality of cylinder liner horizontal parallel to arrange is arranged in the cylinder block relevant position.Present case Unit two is the example explanation, and multiple-unit can be arranged in order.Bent axle is positioned under the cylinder liner; And the gyration center line of bent axle is perpendicular to the cylinder liner center line, and the intake and exhaust piston links to each other in connecting rod through rocking arm separately, and rocking arm is installed on the hydraulic support frame through pitman arm shaft; Hydraulic support frame is installed on the engine body through all cloth bolts; Last oil sump is installed on the bottom plane of engine body through all cloth bolts, and following oil sump is installed on the lower surface of oil sump through all cloth bolts, constitutes the oil sump of motor together.The flywheel 21 of motor is installed on the rear end of bent axle through all cloth bolts, and starting electrical machinery is through the external toothing engagement of starter receiver with flywheel, the startup of realization motor.The front end of bent axle is furnished with oil pump, high pressure fuel pump, cooling waterpump etc., and oil pump drives through the helical gear of crankshaft front end and the helical gear engagement of oil pump, and high pressure fuel pump, cooling waterpump drive through the belt wheel of toothed belt by crankshaft front end.The left and right sides end cap of motor is used to seal motor.

When ato unit, the starting electrical machinery energising is through starter receiver and the engagement of flywheel external toothing; The starting electrical machinery rotation drives the flywheel rotation, and flywheel drives bent axle 12 rotations; Bent axle drives lower link 11, rocking bar 8 motions, and rocking arm drives goes up connecting rod 5 motions, and last connecting rod drives piston and in cylinder liner, moves reciprocatingly; Bent axle drives the to-and-fro motion of piston, cooperates gas exchange process, fuel injection processes etc. to realize the startup of motor, after the cylinder fuel is caught fire, gets into to reach the startup purpose after proper functioning circulates; The starting electrical machinery outage, the starting electrical machinery gear is released engagement, accomplishes start-up course.In the engine starting process, piston is made first stroke movement by outer dead point to inner dead point, and fresh air is pressed into cylinder from suction port 302 under the mechanical supercharger effect.Because exhaust pition 4a shifts to an earlier date 15 ° of-25 ° of CA than air inlet piston 4, therefore, by exhaust pition 4a relief opening 301 is closed earlier.This moment, suction port 302 still continued air inlet; Air inlet piston 4 is closed suction port 302 thereupon.Because air inlet piston 4 moves to inner dead point with exhaust pition 4a simultaneously, the actual compression stroke begins.As exhaust pition 4a during near inner dead point, oil sprayer sprays into cylinder with fuel oil, and the compressed air stream of high-speed motion fully mixes with the vaporific fuel oil that high pressure sprays into; When reaching the diesel oil burning-point; High-pressure diesel burns voluntarily and catches fire, and this moment, exhaust pition 4a crossed inner dead point, and beginning is operation downwards.First stroke finishes, and second stroke begins.When descending 5 ° of-10 ° of CA of exhaust pition 4a; Air inlet piston 4 is positioned at inner dead point; At this moment, taken fire with the well-mixed fuel oil of air and air inlet piston 4 is done work with exhaust pition 4a simultaneously, the cylinder fuel combustion can continue 20 ° of-30 ° of crank angles; When 40 ° of-50 ° of CA of two descent of pistons, burning finishes.Because exhaust pition 4a is than air inlet piston 45 ° of-10 ° of CA in advance, so when exhaust pition 4a opened back 5 ° of-10 ° of CA of relief opening 301, air inlet piston 4 just arrived the position of suction port 302.At this moment, the waste gas that has higher residual pressure is in a large number discharged at a high speed from relief opening 301.When exhaust pition 4a and air inlet piston 4 continues to move to outer dead point; Relief opening 301 is further opened; This moment, suction port 302 was also progressively opened in the outer dead point movement process at the air inlet piston, and under the effect of inertia of high speed exhaust airstream, suction port 302 refluence phenomenons can not take place waste gas.In fact, reasonably the porting position has guaranteed that the cylinder 3 interior pressure of this moment have been lower than suction pressure, so scavenging begins formally to carry out.After air inlet piston 4 is crossed outer dead point, get into compression stroke, suction port 302, relief opening 301 are in almost all open modes; Gas distribution system gets into abundant scavenging period, from the high velocity air that suction port 302 gets in the cylinder 3 waste gas is extruded from relief opening 301, at this moment; Along with piston moves to inner dead point, close relief opening 301 gradually, still; Because the phase difference between air inlet piston and the exhaust pition; The suction port 302 of this moment is still further being opened, and cross outer dead point up to air inlet piston 4 and begin to the motion of inner dead point direction, be that exhaust pition is closed relief opening 301 earlier from phase place; Air inlet piston 4 continues to move to suction port 302 to inner dead point closes, and begins to get into the actual compression stage again.Circulation so moves in circles.
