[0016] The beneficial effect of the present invention is as follows: the present invention obtains a three-pair-door tolerance increment internal combustion rotary engine through the above-mentioned design. When in use, when the rotor rotates clockwise, the front end of the compression door of this group of air intake compression doors in the compression chamber will generate an outward centrifugal force because the swing support center is at the rear end in the rotation direction. When entering the compression chamber through the first air inlet, the front end of the compression door will slide closely against the left inner wall of the middle stator under the action of centrifugal force, thereby squeezing the combustible working medium that entered from the first air inlet in the previous step until the front end passes through the compression chamber and compresses the working medium into the combustion chamber. When the working medium is compressed and stored in the combustion chamber, it is ignited by the spark plug and flame propagation begins, causing the working medium to burn and expand rapidly, lifting up the working door and pushing the working door It rotates together with the rotor to output torque power and completes the conversion of chemical energy into mechanical energy. The compression gate in the same group as the working gate is longer than the working gate. When passing through the working chamber, it is controlled by the front stator and the rear stator and cannot enter the working chamber, and no force is generated to offset the expansion work of the working gate. This enables the working gate to give full play to the tolerance increment effect. The three-pair-gate tolerance increment internal combustion rotary engine has a simple structure, compact structure, small size, light weight, high power density, and a rotor-type internal combustion engine with a body thermal efficiency of more than 60%, which is about 20% higher than the thermal efficiency of internal combustion engines in the prior art, and the manufacturing cost is more than 80% lower than that of piston-type internal combustion engines with the same power and performance, and it has considerable economic and social benefits.

The rotor 2 is provided with a rotor internal cooling lubricant pumping circulation hole 2-6, and the output shaft of the rotor 2 is provided with an ignition position output ring and a flywheel 2-7 and a pulley 2-8. Both ends of the rotor internal cooling lubricant pumping circulation hole 2-6 are inclined holes, and the front end cover 3-18 and the rear end cover 3-19 are respectively fixed to the two ends of the engine housing 3;

[0026] The engine housing 3 is provided with a second air inlet 3-1, a second exhaust port 3-2, a negative pressure zone new air inlet 3-3, a cooling lubricant inlet 3-4, a coolant outlet 3-5, a cooling lubricant temperature sensor mounting hole 3-6, a spark plug hole 3-7, a coolant inlet 3-14 and a coolant outlet 3-15, and also includes an intake pipe connecting seat 3-8 and an exhaust port connecting seat 3-17.

[0027] Specifically, the working principle of the three-door tolerance increment internal combustion rotor engine is as follows: when in use, when the rotor 2 rotates clockwise, the front end of the compression door 2-1 of the group of intake compression doors 2-1 in the compression chamber 1-1 will generate an outward centrifugal force because the swing support center is at the rear end in the rotation direction. When entering the compression chamber 1-1 through the first intake port 1-2, the front end of the compression door 2-1 will slide close to the left inner wall of the middle stator 1 under the action of centrifugal force, thereby squeezing the combustible working medium that entered from the first intake port 1-2 in the previous step, until the front end passes through the compression chamber 1-1 and compresses the working medium into the combustion chamber 2-2. When the working medium is compressed and stored in the combustion chamber 2-2, it is ignited by the spark plug 3-11 and the flame propagation begins, causing the working medium to burn and expand rapidly, lifting the working door 2-3 and pushing the working door 2-3 It rotates together with the rotor 2 to output torque power and completes the conversion of chemical energy into mechanical energy. The compression door 2-1 in the same group as the working door 2-3 is longer than the working door 2-3. When passing through the working chamber 1-4, it is controlled by the front stator 1-8 and the rear stator 1-9 and cannot enter the working chamber 1-4, and does not generate a force to offset the expansion work of the working door 2-3. This allows the working door 2-3 to give full play to the tolerance increment effect. The three-pair-door tolerance increment internal combustion rotor engine has a simple structure, compact structure, small size, light weight, high power density, and a rotor-type internal combustion engine with a body thermal efficiency of more than 60%, which is about 20% higher than the thermal efficiency of the internal combustion engine in the prior art, and the manufacturing cost is more than 80% lower than that of the piston-type internal combustion engine with the same power and performance, and has considerable economic and social benefits.
