The eccentric rotor engine enables the four strokes of air intake, compression, operation, and air exhaust can be continuously carried out at a high speed; moreover, the utility model has the advantages of simple structure, reliable performance, stable running, free air intake and air exhaust, high efficiency, little energy consumption, the conversion rate of energy is high, etc.

Description

The eccentric rotary engine

The utility model relates to a kind of internal-combustion engine, particularly relates to a kind of improvement technology of body of the internal-combustion engine structure.

Motor is the machine that power is provided for motor vehicle or miscellaneous equipment.The crankshaft ﹠ connecting that common motor basic structure is made up of cylinder, piston, connecting rod, bent axle and flywheel etc. constitutes.It has the branch of two strokes and four-journey, because the energy transformation ratio of two-stroke engine is too low, and serious environment pollution is eliminated just gradually.Therefore at present most widely used still four-stroke engine.Four-stroke engine is than the two-stroke engine superior performance, but still it is little to exist the specific power that is difficult to overcome, and energy transformation ratio is not high, the not smooth and big problem of vibrating noise of intake and exhaust.

The purpose of this utility model is to provide a kind of intake and exhaust freely suitable, and the energy transformation ratio height operates steadily, the eccentric rotary engine that vibrating noise small-power density is big.

Scheme of the present utility model is as described below: this model utility comprises air inlet system and exhaust system, lubrication system, combustion system, shell, front and rear cover, eccentric shaft, blade, bolt, by in the enclosure or the rotor that an eccentric shaft is set in the body of bivalve and constitutes with the eccentric shaft one, be provided with the blade that slides along rotor radial on the rotor in the groove of even cloth, and be provided with on front and rear cover that the inlet and outlet mouth of mutual dislocation realizes.

The utility model is owing to taked structures such as eccentric rotor and sliding blade, the combination of prior art in addition, make this model utility can not only reliably realize goal of the invention, air inlet, compression, work done, exhaust four-journey continuous high speed are carried out, and has simple in structure, reliable performance, operate steadily, the high power consumption of efficient is little, the energy transformation ratio advantages of higher.

Below in conjunction with accompanying drawing scheme of the present utility model is described in further details:

Fig. 1 is the overall structure schematic representation of eccentric rotary engine;

Fig. 2-Fig. 4 is the agent structure schematic representation of eccentric rotary engine;

Fig. 5 is the rotor structure figure of eccentric rotary engine;

Fig. 6 is the rotor structure A-A sectional view of eccentric rotary engine;

Fig. 7 is the rotor and the blade-section structural drawing of eccentric rotary engine.

By eccentric rotary engine shown in Figure 1 is by engine main body 1, gas handling system 2, and vent systems 3, combustion system 4, lubrication system 5 combine formation.Key technology of the present utility model is engine main body 1.Fig. 2, Fig. 3 are respectively mono-hull of the present utility model and two kinds of different structure forms of bivalve body.(as Fig. 3, Fig. 4) its outside is a shell 6 to its mono-hull, and shell 6 bolts at two ends are connected and fixed front and rear cover 7,8, and the inlet and outlet mouth of mutual dislocation is arranged on the front and rear cover 7,8.The rotor 10 that is provided with the eccentric shaft different with shell 6 centers of circle 9 in the shell 6 and constitutes with eccentric shaft 9 one is established equally distributed vertically groove 11 on the rotor 10, groove 11 bottom intermediate holes communicate with rotor 10 center holes (seeing Fig. 5,6).The blade 12 that radially slides along rotor 10 is arranged in the groove 11.Blade 12 tops are an arc, the eccentric shaft 9 built-in magnetic patch 14 corresponding (see figure 7)s of the built-in magnetic patch 13 in bottom and rotor 10.Different is to set up an inner housing concentric with it 15 in shell 6 for double-shell structure (as Fig. 2) and mono-hull, is provided with rolling element between the inside and outside shell 15,6, and inner housing 15 is hinged with the top of blade 12.Cancel magnetic patch built-in on rotor eccentricity axle 9 and the blade 12 14,13 simultaneously.Fixing blower fan on the forward end cap 7 lateral deviation axles 9 inserts suction port by suction tude, and relief opening is connected with outlet pipe.Its lubrication system 5 is introduced eccentric shaft 9 center holes with lubricant oil and flowed directly into each groove 11 intermediate hole to groove 11, and is lubricated and regulate positive negative pressure in the groove 11 for blade 12.Its combustion system 4 can be by inserting on rear end cover (double-shell structure) 8 or the shell (single shell structure) 6.

(see figure 3) during work, shell 6 is static, and the reaction force that centrifugal force, the magnetic patch that rotor 10 rotations produce is 13,14 and the restriction of shell 6 force blade 12 radially moving reciprocatingly along rotor 10 in groove 11.Pressing direction shown in the figure when rotor 10 rotates, along with the rotation of rotor 10 and the slip of blade 12, the air that suction port is sent into is compressed gradually, and air pressure maximum when any adjacent two blades 12 move to the a-quadrant and volume compression minimum are in combustion system 4 effect down-firings burnings.The high-temperature high-pressure fuel gas that burning produces is along with inertia certainly will promote regional the moving of B, C, D that blade 12 orders increase to the space.Arrive D zone relief opening combustion gas, suction port is sent into fresh air.Just can finish a cyclic process.When working for the double-shell structure (see figure 2), inner housing 15 in the bivalve rotates with blade 12, rotor 10, be both axle center differences, and the hinge of taking between blade 12 and the inner housing 15 is connected and has remedied the angular velocity difference that eccentric rotary is brought on the one hand, can improve the degree of wear at blade 12 tops simultaneously.The periodic duty process is identical with mono-hull and outputed power by eccentric shaft 9.
