1. U.S. Pat. No. 6,250,263 will reference a few descriptions of this invention which are inferior to the description of my text:
2. Page 2 of 13, paragraph 1, sub-paragraph which reads “at least two cylinders, each said cylinder having separate crank ends, separate face ends and separate central axis.”
3. Page 3 of 13, paragraph 11, sub-paragraph which reads “at least two cylinders, each said cylinder having separate crank ends, separate face ends and separate central axes.”
4. Page 4 of 13, paragraph 14, sub-paragraph which reads “at least two cylinders, each cylinder having a crank end and a face end.”
5. Page 4 of 13, paragraph 19, sub-paragraph which reads “at least two cylinders, each said cylinder having separate crank ends, separate face ends and separate central axes.
The dual rigid rocker marriage should revolutionize the dual piston engine. This concept is the most economical way to inner connect the dual piston to the output train. This rigid rocker marriage will finally enable the dual piston concept to be constructed economically and be more efficient than the separate crank end concept.
The dual piston concept, utilizing the rigid rockers can be constructed much lighter and smaller, do the same amount of work, using less fuel, and have longer life. Rigid rockers will significantly reduce the cost, increase performance, and reduce the weight of a dual piston engine. This engine concept may operate using any fuel, Liquefied Natural Gas (LNG) diesel, gasoline, or kerosene.

1. Dual pistons (1) and (2) move outward on its combustion cycle, forcing rigid rockers 7 and 8 away from each other at points (3) and (4). Points (9) and (10) are forced towards each other, causing a clock wise rotating action of points (11) and (12) this energy is transferred to output shaft (13). Points (5) and (6) are center support axis for the rigid rockers 7 and 8. While the dual pistons move away from each other, they travel approximately {fraction (1/2)} the distance of a single piston conventional engine, allowing a dual piston engine to cycle at higher (RPM) rotations per minute.
2. In a single piston concept, the single piston cycles in it's cylinder against a fixed head, causing some energy to be lost compared to this dual concept.
3. In this dual concept, the two opposing pistons travel too and fro in a single cylinder allowing for higher compression in the cylinder, which will increase the engine's efficiency.
4. By the two pistons moving to and fro in a single cylinder will allow for greater heat dissipation. A great amount of heat is generated against the stationary head of a single piston cylinder requiring greater cooling action of the head. The additional heat generated against the stationary head of a conventional engine may equal additional energy loss and ware.
5. Due to the imposing thrust upon the crank shaft 90° apart in a dual piston configuration will cause equal opposing forces upon the crank shaft. These opposing forces will cause main bearing ware to be closer to zero.
6. Proportionally, more work will be accomplished in a dual piston engine, using less fuel to achieve the same work.
7. Due to pistons (1) and (2) traveling about ½ the distance of a conventional engine, each piston will ware longer.
8. By the rockers 7 and 8 actuating to and fro approximately 45° in each direction from their axis at (5) and (6) the piston rods wag less on their axis (1), (2), (3)& (4) in a complete 4 cycle revolution compared to a 360° cycle of a conventional engine. The “dual face to face rigid rocker marriage concept” will enable the construction of piston rods and pistons to be much lighter in weight, allowing for higher RPM'S.
9. The connecting links (9) and (10) may be constructed more rigidly to the crank since piston rods (3) and (4) won't be directly associated to the output crank.
10. The rigid rockers 7 and 8 may be constructed much cheaper than a crank shaft, and will certainly last longer, since there won't be a 360° cycle. These rockers will cycle about 45° to and fro of its axis (5) and (6) 4 strokes to complete 4 cycles of the engine operation (intake-compression-combustion, and exhaust).
