Exhaust stroke: refer to Figure 21, first piston block 208 turns to relief opening 105 place, and be rotated further relief opening 105 is opened, now the 3rd piston block 210 is in the movement process of the expansion stroke of another work cycle, rotate towards first piston block 208, and the gas between first piston block 208 and the 3rd piston block 210 is discharged by relief opening 105.
Refer to Fig. 1 ~ Figure 21, in above-mentioned four stroke procedure, first piston block 208 is when rotating, drive the differential transmitting linkage action near protecgulum 107, namely the driving disc 301 of this end rotates, and by first connecting rod 302, control ring 401, second connecting rod 303 thus drive driven disc 304 rotate, driven disc 304 drives main shaft 102 to rotate, outputting power.Outburst angle of deflection plays the effect of guiding, and double-loop control mechanism confined piston group 201, make it carry out the accurate motion of non-in the same way constant speed according to the differential parameter calculated.Complete engine operational cycle is formed by above four strokes.
The 3rd piston block 210 in addition and the movement process of the second piston block 209, second piston block 209 and the 4th piston block 211, the 4th piston block 211 and first piston block 208 and said process similar, do not repeating at this.Should be understood that, in the rotation process of two groups of piston groups 201, be carry out four-stroke motion separately between adjacent two piston blocks 202, and it is drive the differential transmitting linkage action of both sides respectively that two piston groups 201 are rotated.So, main shaft 102 is in rotating 360 degrees process, and in fact carried out 4 outburst actings, its dynamic curve is continuous parabola state, is different from the cosine formula dynamic curve of traditional reciprocating piston and rotary polygonal piston engine.Therefore, the energy transformation ratio of this Harvard's formula hydrogen rotary engine is higher than existing reciprocating piston and rotary polygonal piston engine.
In sum, Harvard's formula hydrogen rotary engine that the present embodiment provides at least has the following advantages:
1. energy transformation ratio is higher, and structure is more simple, and manufacturing process is simple, and be convenient to manufacture, cost is lower.
2. hydrogen can be adopted as power source, and energy consumption is low, environmental protection.
3. do not need to arrange traditional inlet and exhaust valve device, can natural intake and exhaust, avoid occurring that gas increases sharply phenomenon suddenly.
4. four strokes are respectively in diverse location, so oil nozzle on motor and spark plug 103 can not work for a long time under high-temperature high-pressure state, part durability improves.
5. exhaust is independently stroke space, so be not afraid of water logging, this feature comparatively conventional engine is more practical.
6. its output power of plural serial stage can increase, and its applicability is wider.
Harvard's formula hydrogen rotary engine that the present embodiment provides is owing to can adopt hydrogen as power source, therefore its application area widely, such as, for ambient air the comprehensive regulation, build cleaning type society's railway and highway system and develop and sell product, the equipment of hydrogen energy source; Jeopardize the environment-friendly engineering of the mankind with husky sand control comprehensive regulation desertization and develop product, the equipment of selling patent chemical industry ingredients; For the exploitation of helicopter, unmanned plane, aerospace vehicle, development, sale; For boats and ships, naval vessels, the exploitation of ocean navigation device, development, sale; For the exploitation of the land craft of special vehicle, car, tank, armored vehicle and component, development, sale; For war humanoid robot, fire-fighting robot, the exploitation of nuisanceless generator set, development, sale.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
