(11) After the power wheel 20 is slidably installed to the circular cylinder 101 of the cylinder seat 10, both sides of the power wheel 20 are sealed by a side cover 16, and the transmission shaft 201 installed at the center of the power wheel 20 and pivotally installed to a positioning frame 17 in a free rotation manner, and the positioning frame 17 is fixed to the cylinder seat 10, so that the power wheel 20 can be rotated smoothly and stably.

(12) The peripheral surface of the power wheel 20 has a compression chamber 202 with a bottom 2021 preferably being a cambered surface, so that when the power wheel 20 is rotated, the gas barrier member 132 of the compression means 13 elastically presses the cambered surface of the compression chamber 202 to achieve the airtight effect.

(13) The compression chamber 202 disposed on the peripheral surface of the power wheel 20 has a volume greater than the sum of the volume of the first explosion chamber 1012 and the volume of the second explosion chamber 203.

(14) With reference to FIG. 3 for the rotary internal combustion engine of the present invention, the power wheel 20 is slidably installed to the circular cylinder 101 of the cylinder seat 10 in a free rotation manner, and both sides of the power wheel 20 are sealed by a side cover 16, so that the first explosion chamber 1012 of the cylinder seat 10 and the compression chamber 202 and the second explosion chamber 203 of the power wheel 20 are maintained as a closed space. When the power wheel 20 is rotated, the compression chamber 202 and the second explosion chamber 203 on the peripheral surface of the power wheel 20 are configured to be corresponsive to the first explosion chamber 1012, the fuel supply system 12, the compression means 13, the exhaust means 14, and the intake means 15 of the cylinder seat 10, and the fuel gas inputted by the fuel supply system 12 and the fresh air inputted by the intake means 15 are mixed and entered into the compression chamber 202 and the second explosion chamber 203 automatically together with the rotation of the power wheel 20, and the mixed fuel gas will be leak to the outside. In the meantime, the gas barrier member 132 installed at the compression means 13 of the cylinder seat 10 has a forward elastic action force for pressing the peripheral surface of the power wheel 20 anytime. When the gas barrier member 132 is configured to be corresponsive to the compression chamber 202, it will elastically pressed and automatically maintain an airtight effect with the periphery of the compression chamber 202. As the power wheel 20 rotates, the mixed fuel gas entered into the compression chamber 202 will be compressed by the gas barrier member 132 of the compression means 13 to enter into the first explosion chamber 1012. Since the second explosion chamber 203 disposed adjacent to the compression chamber 202 will be configured to be corresponsive to the first explosion chamber 1012 while the power wheel 20 is rotated, so that the mixed fuel gas accommodated in the second explosion chamber 203 and the mixed fuel accommodated in the first explosion chamber 202 will be compressed by the compression means 13 and collected into the first explosion chamber 1012 and the second explosion chamber 203.

(15) Since the total volume of the first explosion chamber 1012 and the second explosion chamber 203 is smaller than the volume of the compression chamber 202, the compressed fuel gas is collected into the first explosion chamber 1012 and second explosion chamber 203 after the fuel gas in the compression chamber 202 is compressed by the compression means 13, so as to facilitate the ignition and explosion.

(16) When the power wheel 20 is turned on and rotated, the compression chamber 202 and the second explosion chamber 203 disposed on the peripheral surface of the power wheel 20 are configured to be corresponsive to the intake means 15 and the fuel supply system 12, the inputted fresh air and fuel gas will be entered and mixed in the compression chamber 202 and the second explosion chamber 203 of the power wheel 20, and the gas barrier member 132 of the compression means 13 is provided for an elastic pressing to maintain the airtight effect of the peripheral surface of the power wheel 20 and the periphery of the compression chamber 202, so that the mixed fuel gas entered into the compression chamber 202 will be compressed forcibly by the gas barrier member 132 of the compression means 13 to enter into the first explosion chamber 1012 as the power wheel 20 rotates. In the meantime, the second explosion chamber 203 disposed adjacent to the compression chamber 202 also rotates with the power wheel 20 and aligns with the first explosion chamber 1012, so that the mixed fuel gas accommodated in the second explosion chamber 203 and the mixed fuel gas accommodated in the first explosion chamber 1012 are compressed by the compression means 13 and collected into the first explosion chamber 1012 and the second explosion chamber 203. Since the total volume of the first explosion chamber 1012 and the second explosion chamber 203 is smaller than the volume of the compression chamber 202, so that the mixed fuel gas compressed by the compression chamber 202 and collected into the first explosion chamber 1012 and the second explosion chamber 203 are in a compressed status. Since the ignition system 11 installed at the cylinder seat 10 is configured to be corresponsive to the first explosion chamber 1012, the compressed fuel gas collected into the first explosion chamber 1012 and the second explosion chamber 203 is ignited by the ignition system 11 instantaneously for an explosion to produce a high explosive yield; and the first explosion chamber 1012 installed at the cylinder seat 10 remains still, and the corresponsive second explosion chamber 203 is installed at the power wheel 20 with a free rotation, so that the compressed fuel gas collected into the first explosion chamber 1012 and the second explosion chamber 203 will be ignited by the ignition system 11 for an explosion to produce a high explosive yield, and a large force is formed naturally and applied to the second explosion chamber 203 to drive the power wheel 20 to rotate at a high speed. The compression means 13 has an exhaust means 14 installed on a side of the compression means 13, so that the compressed fuel gas in the first explosion chamber 1012 and the second explosion chamber 203 will be ignited for an explosion to produce waste gas, and when the power wheel 20 rotates the second explosion chamber 203 to a position corresponsive to the exhaust means 14, the waste gas will be exhausted and discharged to the outside. Therefore, the invention overcomes the poor exhaustion effect of the conventional two-stroke internal combustion engine or the issue of the conventional four-stroke internal combustion engine requiring additional two strokes of the piston and wasting kinetic energy to compress and exhaust the waste gas.

(17) By the rotation of the power wheel 20, the mixed fuel gas supplied from the intake means 15 and the fuel supply system 12 into the compression chamber 202, the mixed fuel gas will be compressed by the compression means 13 and collected into the first explosion chamber 1012 and the second explosion chamber 203, and then ignited by the ignition system 11 for an explosion to produce a large driving force to push the power wheel 20 to rotate, and the power wheel 20 will always rotate unidirectionally and naturally without being affected by the inertia force, so as to achieve the effect of providing high-efficiency kinetic energy.

(18) In FIGS. 4, 5, and 6, at least one first explosion chamber 1012 is formed on the peripheral surface of the cylinder wall 1011 of the cylinder seat 10, and at least an ignition system 11, a fuel supply system 12, a compression means 13, an exhaust means 14 and an intake means 15 are installed at the outer periphery of the cylinder seat 10 of each first explosion chamber 1012, and at least one compression chamber 202 and second explosion chamber 203 are disposed on the peripheral surface of the power wheel 20. According to actual requirements, the first explosion chamber 1012, the ignition system 11, the fuel supply system 12, the compression means 13, the exhaust means 14, the intake means 15, the compression chamber 202, and the second explosion chamber 203 may come with a plural quantity, so that the force and speed for driving the power wheel 20 to rotate will be improved to provide a larger quantity of kinetic energy. Since the cylinder 101 of the cylinder seat 10 and the power wheel 20 of the present invention are in a circular shape, the size of the cylinder 101 and the power wheel 20 may be increased to allow the construction of more first explosion chambers 1012, ignition systems 11, fuel supply systems 12, compression means 13, exhaust means 14, intake means 15, compression chambers 202, and second explosion chambers 203, so that the power wheel 20 can provide more and higher-efficiency kinetic energy.

(19) The plurality of first explosion chambers 1012, compression chambers 202, and second explosion chambers 203 are preferably arranged equidistantly on the cylinder wall 1011 and the peripheral surface of the power wheel 20. Preferably, any two equidistant first explosion chambers 1012 are not disposed on diagonals having an angle of 180 degrees with respect to each other, so that the pushing force produced by the explosion of the fuel gas and exerted onto each first explosion chamber 1012 and the second explosion chamber 203 will not be offset, and the unidirectional rotation of the power wheel 20 is maintained smoothly and naturally to achieve the effect of providing high-efficiency kinetic energy.

(20) Since the environment of compressing and igniting the fuel gas varies, the compression chamber 202, and the first explosion chamber 1012 operated with the second explosion chamber 203 are preferably separated, so that the internal combustion engine of the present invention has a diversified fuel supply (in other words, fuels of high ignition point or low ignition point may be used for the operation), so as to achieve the effect of broadening the scope of applicability.

(21) After the compressed fuel gas collected into the first explosion chamber 1012 and the second explosion chamber 203 are exploded and combusted and the produced waste gas is exhausted and discharged to the outside successfully, some of the loosened waste gas may still remain in the space of the second explosion chamber 203, but the remained waste gas is similar to the waste gas remained at the gap between the cylinder and the cylinder cover while the piston of the four-stroke internal combustion engine compresses and exhausts the waste gas, which does not have any substantial effect on exploding and combusting the introduced fresh fuel gas, and thus the invention achieves a full combustion effect and complies with the requirements of pollution protection.

(22) It is noteworthy that the first explosion chamber 1012 is installed to the fixed cylinder seat 10, and the second explosion chamber 203 is movably installed to the freely rotating power wheel 20, so that when the ignition system 11 ignites the compressed fuel gas collected into the first explosion chamber 1012 and the second explosion chamber 203 for an explosion, the fixed first explosion chamber 1012 provides a reaction force of the exploded fuel gas to the second explosion chamber 203 directly, so that after the freely rotating second explosion chamber 203 receives the reaction force, a larger pushing force will be produced to push the power wheel 20 to rotate, so as to improve the efficiency of generating kinetic energy.

(23) In other words, the present invention has the following advantages:

(24) 1. The internal combustion engine features simple configuration, and easy and convenient assembling and operation.

(25) 2. The internal combustion engine provides high-efficiency kinetic energy.

(26) 3. The waste gas of the internal combustion engine can be exhausted successfully and smoothly to achieve a clean effect.

(27) 4. The internal combustion engine provides a diversify fuel supply to broaden the scope of applicability.
