Inventor finds by carrying out contrast with existing reciprocating-piston engine:

1, it is not subjected to promote the push and draw force of crank rotation, piston due to the piston of the present invention Structure greatly simplify, the requirement of strength of piston material is substantially reduced, and whole mechanism exists Vibration in operation process is little, noise is little.

2, structure simple in construction of the present invention and volume are little, easy-maintaining, easily maintain, and beneficially automobile Enging cabin carries out improving and the layout of other useful mechanisms of other associated components.The present invention lives Plug structure is simple, size is little, low cost, readily replaceable.

3, power output equalizes, compacts: at working stroke, when beginning explosive force is big, piston is subject to Power sectional area is little；Acting latter end explosive force hour piston lifting surface area is big, thus makes power Output equilibrium；Rotor of the present invention often rotates one week, continuous doing work six times, and an expansion stroke exists During acting end, next new expansion stroke just starts.

4, conventional engine, dynamic in order to improve, often use and increase number of cylinders Way, but when number of cylinders increases, and mechanical friction loss is increasing, separately, because of with cylinder Quantity increases, and connecting rod quantity also increases, and causes bent axle more and more longer, adds the antitorque system of bent axle Several rigors to crankshaft material.And power of the present invention output the most very homogenizing, do not exist past The problems referred to above that piston engine exists.

5, conventional reciprocating piston-mode motor, at air inlet compression stage by bigger pressure Atmidometer, compression ratio is the biggest, and the negative work that compression stage consumes is the biggest.And the present invention is in air inlet Compression stage, piston is just being met the sectional area of calming the anger turned to and is also being gradually reduced, therefore whole row of calming the anger Journey, resistance of calming the anger suffered by piston is little, and the merit of calming the anger of consumption is few, thus improves and effectively export torsion Square and effective output.

6, the resistance of air inlet compression travel of the present invention is little, and therefore, it is at low, medium speed Efficiency time (less than 3000 revs/min) is apparently higher than conventional engine.Therefore, originally Invention is more suitable for car urban traffic situation.

8, traditional reciprocating-piston engine, needs to arrange a set of oil spout in each cylinder Igniter, and the present invention has only to arranging oil spout igniting dress near cylinder ends Put, the maintenance cost in reducing manufacturing cost and using.

Additionally, the present invention is also compared by inventor with existing rotary polygonal piston engine, send out The existing present invention has the property that

1, the major reason that rotary polygonal piston engine oil consumption is high: from center of rotation to its turn Sub-end face make a normal, at working stroke, normal both sides by the gaseous-pressure of contrary rotation direction, Thus, considerable part effective power is cancelled, and the present invention does not the most exist this problem.

2, the top land of existing rotary polygonal piston engine is sharp stupefied shape, can only arrange one Sealing strip, its sealing effectiveness is poor, and the top land of the present invention can be designed to relatively round flat, can To arrange a plurality of sealing strip, sealing effectiveness is preferable.

3, the admission space that inner cavity chamber of the present invention, exocoel add up to is big, it is possible to achieve compare triangle The compression ratio that piston rotary engine is much higher, more effectively improves fuel efficiency and power is defeated Go out.

4, the type of drive (tooth is than 3:1) of the little gear of rotary polygonal piston engine canine tooth wheel belt, Its moment of torsion being substantially reduced, and the present invention is just the opposite, the common reciprocating-piston of torque ratio starts Machine is substantially big, and torque ratio rotary polygonal piston engine is more much greater.

5, the present invention is without arranging eccentric structure, can reduce rotor in rotation process to cylinder body Impulsive force, thus reduce the vibration of cylinder body.

6, the piston of rotary polygonal piston engine connects together with travelling gear, if needing to change Piston, the most with high costs, inventive piston simple in construction, size are little, low cost, the most more Change.

7, rotary engine air inlet compression travel, its just meeting turn to calm the anger cut Area is big (bigger than the sectional area of calming the anger of reciprocating-piston engine), thus triangle piston turns The loss of sub-engine charge compression travel kinetic energy (power, moment of torsion) is big, and this electromotor Because the resistance of air inlet compression travel is little, thus, kinetic energy (power, moment of torsion) loss ratio three Angle rotary engine is the least.

The present invention is compared with existing vane rotor engine, finds that the present invention has Following characteristic:

1, there is following defect in vane rotor engine: in (1) operating, vane stress Form fierceness between back of the body loin and the stupefied limit of support zone, rotor upper end cuts wiping to pieces；And blade is low Portion forms scraping with rotor respective support portion, and therefore blade is easily damaged.(2) the thinest Blade, it is difficult to a plurality of sealing strip of reasonable Arrangement, inventive engine use shake the head piston the most not Deposit above-mentioned problem.

2, compare vane rotor engine, the present invention because have employed inside and outside chamber design, Its " cylinder " volume and compression ratio all greatly improve；And under same size, " the vapour of the present invention Cylinder " volume is relatively big, thus power, the moment of torsion under same size is the most much larger.

It will be apparent to those skilled in the art that can technical scheme as described above and structure Think, make other various corresponding changes and deformation, and all these changes and deformation Within all should belonging to the protection domain of the claims in the present invention.
