Fig. 2 is the side view of sharp elliptic cam formula rotary engine structural representation.
Among the figure: the 1st, circular cylinder body, the 2nd, cam-type piston, the 4th, spark plug, the 7th, pressurized gas import, the 8th, safety check, the 9th, compression gas pipe, the 10th, pressurized gas outlet, the 11st, gas booking groove, the 12nd, cooling turbine, the 13rd, output shaft, the 15th, end face seal bar.
1) chamber A ' and quick-fried row chamber A are pressed in structural type, arc working room-suction of forming two variable volumes by circular cylinder body 1 and cam-type piston 2 and post rod type cylinder cap 3 ".
Spark plug 4 is located on the periphery of top, and suction port 5 and relief opening 6 are located on the periphery of below, and is separated by bottom post rod type cylinder cap 3.
Pressurized gas import 7 is located at inhales on the end end face of pressing chamber A ', the 8th, safety check, compression gas pipe 9 bears very big pressure, be located at the both sides of engine body exterior end face, be convenient to check dismounting, the 10th, pressurized gas outlet, it combines with gas booking groove 11 on the piston, controls switching and timing distribution between two working rooms.
Cam-type piston 2 and cooling turbine 12 all are fixed on the output shaft 13.
Apex seal 14 and end face seal bar 15 and link block 16 are the good sealing in working room.
Spring 17 compresses post rod type cylinder cap 3, makes it closely connected on the periphery of cam-type piston, can only slide and can not separate.
2) working principle, the main purpose of the present invention are that the four-journey work cycle is divided into two groups, are finished respectively by two working rooms.
Mixed gas enters to inhale from suction port 5 presses chamber A ', and cam-type piston 2 rising edge compression strokes and trailing edge suction stroke carry out simultaneously, and compressed gas import 7 of compressed mixed gas and safety check 8 enter in the compression gas pipe 9 of engine body exterior.
Gas booking groove 11 matches with pressurized gas outlet 10 after the protruding peak of piston 2 turns over top post rod type cylinder cap 3, mixed gas pours the quick-fried row chamber A of internal body with the situation of puffing "; still keep enough compression ratios this moment; when gas booking groove 11 and pressurized gas outlet 10 are closed mutually; spark plug 4 is lighted mixed gas and expanded; the trailing edge of piston 2 converts gaseous-pressure the rotary torsion of machinery to and exports, rising edge is discharged waste gas simultaneously from the relief opening of often opening 6, finished a work cycle.
3) torsion output, major function of the present invention are that cam-type piston 2 is fixed on the output shaft 13, and are contained on the center of circle of cylinder body 1, rotate along circular path with constant angular velocity, are desirable pure " rotor " motors.
The output shaft igniting twice of whenever circling all obtains rotary torsion on 360 ° of the Shaft angles, and is original and valuable especially.
The present invention and existing triangle piston engine compare:
1) structure: the jib complex structure, the envelope line style cylinder body of 8 fonts and piston manufacturing maintenance are all very difficult, and cam machine circular cylinder body simple in structure and cam-type piston manufacturing maintenance are all than being easier to.
2) principle: jib is to swing the circuit of finishing the work in turn by three angles of piston in two arc working rooms, the centrifugal force that apex seal produces in different quadrants, Ke Liaoli (Coriolisraft) power bump casing wall serious wear, though adopt the spraying abrasion-proof metal to use materials such as silicon nitride, it is reinforcement and strengthening, this kind active force can not be eliminated at all, and enduring quality is very low.
The torsion of jib is exported by the inner chamber extruding eccentric shaft of triangle piston, and piston and output shaft are unfixing, and a gear that resembles that is used for locating falls tooth sometimes, and the damaged accident of seizure of piston generation machine, unfailing performance is also very poor.
The piston of cam machine is to rotate along circular path with constant angular velocity in the cylinder body of circle, is pressed on the casing wall uniformly when apex seal is subjected to centrifugal action and slides, and piston and output shaft are on the center of circle of fixing that is contained in cylinder body, do not have above-mentioned defect.
Post rod type cylinder cap spring compression, closely connected on the periphery of cam-type piston, can not produce and separate or bump, this mechanics method is solved by current science and technology.
3) output: the jib eccentric shaft whenever circles igniting once, and twisting force is on 270 ° of Shaft angles.
The igniting twice of whenever circling of cam machine output shaft, this is very superior to twisting force on 360 ° of Shaft angles.
The more important thing is that moment of torsion decline performance software feature can only be contained on the sedan car during jib low speed, can not use on the truck that the starting of load low speed is arranged.
Moment of torsion shows as hardware features during cam machine low speed, oxen and horses characteristic, and the driving of leting people has been applicable to load low speed starting truck and any vehicle or ships and light boats, and adaptability is widely arranged.
Realize the present invention, when utilizing structural principle of the present invention, it mainly is the mechanical relationship of cam and push rod, the post rod type cylinder cap still can be tightly closely connected when making the cam-type piston high speed rotating, the line style of cam and basic circle will adapt with moving-mass inertial force, speed acceleration etc., must select the cam line style with theoretical calculation method or experimental technique.
Elder generation's bar structure original paper is simplified to dynamic model and programs during calculating, with simple substance systems approach or many matter systems approach, can solve the function line style of the best with electronic computer.
During actual verification, cam angle and lift, corner and speed of drawing or acceleration coordinate curve can obtain proof, and this method all has argumentation in Der Grundsatz der Maschinen in the mechanical design course.
The cam machine is simple in structure, and technical equipment and quality of materials do not have specific (special) requirements during manufacturing, and general internal-combustion engine is made factory and all can be born.
The effect of cammingly rotary piston engine of the present invention is very considerable, and it is simple in structure and superior, possesses endurance, reliability, and the mandatory attribute of motors such as adaptability, this invention not only will have academicly and significance economically at home and in the world.
