DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a conventional triangular piston rotary engine is mainly composed of a cylinder A and a triangular piston B.
An intake port A1 and an exhaust port A2 are provided at the top of the fuel cell, and a spark plug A3 is provided at the bottom thereof.
The triangular vertices B1, B2, B3 of the piston B divide the cylinder A into three, C, D, E uncommunicated air chambers, the piston B rotating around an eccentric axis F.

As shown in FIG. 1A, the air chamber C is being compressed, the air chamber D is being expanded, and the air chamber E is being exhausted. As shown in FIG. 1B, the exhaust of the air chamber E is completed, the air of the air chamber C is being ignited after the gas compression is completed, and the air chamber D is being discharged immediately after the expansion is completed.

As shown in FIG. 1C, the air chamber C is ignited and starts to burn, the air chamber E is still inhaling even after exhausting, and the air chamber D is exhausting. As shown in FIG. 1D, the air chamber C has already been ignited and expanded, the air chamber D is about to start exhausting, and the air chamber E is about to start compressing. 1 (A) to FIG. 1 (D), the piston B rotates once around the eccentric shaft F.
Each of the air chambers C, D, and E has completed one gas cycle. However, the drawback is that these triangle vertices B1 and B2
・ The long-term contact between B3 and cylinder A is not
In addition to preventing airtightness between D and E, the piston B cannot completely isolate the air chambers due to the accuracy during manufacture and subsequent wear, which has a huge impact on the gas cycle. Is given.

In order to improve the above-mentioned defect, a part of the apex of the piston B is cut off to form a cutout portion B4 as shown in FIG.
In addition, a radial narrow groove B5 is provided thereon, and a leakage prevention plate G is incorporated in the narrow groove B5. The function is to tightly press against the cylinder wall by utilizing the centrifugal force generated when the piston B rotates, thereby achieving the purpose of preventing leakage. Further, when the piston B is incorporated into the cylinder A, the cylinder head H is closed at the upper and lower ends along the axial direction of the cylinder B to seal the cylinder. In fact, since it is difficult to maintain the airtightness between the cylinder head H and the end face of the piston B, a groove B6 is provided on the piston B to prevent gas in the air chamber from leaking from the end face. The end face sealing plate K is inserted. The end seal plate K and the leakage prevention plate G are connected by a short cylinder M. Further, between the upper and lower two short cylinders M, a considerable sealing pressure is applied between the end seal plate K and the cylinder head H. A spring is provided.

As can be seen from the above, whether the leak prevention of the triangular piston type rotary engine used so far is sufficient is the greatest key point whether or not the gas cycle can be completed completely. . However, the sealing method still has the following disadvantages. one. The contact between the sealing plate at the top and the cylinder wall is only due to centrifugal force, and there is no external pressure, so that a gap that freely expands and contracts also occurs.

Two. The piston must be an equilateral triangle because it is limited by the cylinder outer shape, and unbalanced vibrations occur during eccentric rotation. three. Since only one ignition system is installed, it cannot respond to prolonged combustion. Four. The seal plate on the end face has a gap between itself and the piston due to thermal expansion or cold contraction, and since it is installed in the piston, maintenance is not easy.

As can be seen from the above, the conventional triangular piston type rotary engine still has various severe drawbacks, and in view of this, the inventor of the present invention has continually researched and improved and developed the internal combustion engine. The experience of engaging in
