The partition 201 has a first cylinder chamber 100 on the left side and a second cylinder chamber 200 on the right side.
(1) An air inlet stroke:
an external starter drives a starting flywheel 10 to drive a crankshaft 9 to rotate, a connecting rod 8 rotates on the crankshaft 9 to drive a crank 7 and a rotor 2 to rotate, and the rotor 2 drives a partition plate 201 to rotate from a built-in valve seat 3 on the left side of the partition plate to a built-in valve seat 3 on the right side of the partition plate. In the built-in valve seat 3 on the left side of the partition 201, the intake passage pressure of the intake valve 401 is higher than the pressure of the first cylinder chamber 100, the intake valve 401 is automatically opened to quickly intake air into the first cylinder chamber 100, and the linked exhaust valve 501 in the built-in valve seat 3 is not closed to perform scavenging. Because the exhaust is pressurized to the air inlet channel through turbocharging, when the partition plate 201 rotates to the right built-in valve seat 3, the connecting rod 8 drives the rotor 2 to rotate reversely, when the partition plate 201 rotates one third of the way from the right built-in valve seat 3 to the left built-in valve seat 3, the linkage exhaust valve 501 and the air inlet valve 401 are closed simultaneously, at the moment, when the pressure of the first cylinder chamber 100 is greater than that of the air inlet channel, the air inlet valve 401 is automatically closed, and the first cylinder chamber 100 realizes an 'air inlet stroke'.
(2) Compression stroke:
the linkage exhaust valve 501 and the intake valve 401 in the left built-in valve seat 3 are closed at the same time, the partition plate 201 rotates continuously from the right built-in valve seat 3 to the left built-in valve seat 3, the space of the first cylinder chamber 100 is gradually reduced, and the partition plate 201 gradually compresses air in the first cylinder chamber 100, so that the pressure and the temperature are gradually increased, and the compression stroke is realized.
In this process, the intake valve 401 of the valve seat 3 built in the right side of the partition 201 is opened, and the "intake stroke" is realized in the second cylinder chamber 200.
(3) The working stroke is as follows:
when the partition plate 201 rotates to the left built-in valve seat 3, the linkage exhaust valve 501 and the intake valve 401 are still closed, and high temperature is generated due to air compression, at the moment, the oil nozzle 6 in the left built-in valve seat 3 injects oil into the first cylinder chamber 100, a large amount of heat energy is released by instantaneous combustion work, the volume of combustion gas is expanded rapidly, reverse thrust is generated, the partition plate 201 is pushed to rotate rapidly in the reverse direction, and the first cylinder chamber 100 realizes 'work stroke'. Simultaneously, the burning does work and promotes drive connecting rod 8 and drive bent axle 9 rotation when baffle 201 counter-rotation, and then will the utility model discloses a power transmission that arc motion rotary engine produced goes out.
In the process, the partition plate 201 rotates towards the right built-in valve seat 3, the space of the second cylinder chamber 200 is gradually reduced, the pressure and the temperature are gradually increased, the intake valve 401 and the linkage exhaust valve 501 in the right built-in valve seat 3 are also closed, and the second cylinder chamber 200 realizes a compression stroke.
(4) An exhaust stroke:
when the partition 201 rotates to the right built-in valve seat 3, the connecting rod 8 rotates around the crankshaft 9 under the inertia effect, so that the rotor 2 and the partition 201 are driven to rotate reversely, and the partition 201 rotates towards the left built-in valve seat 3. Meanwhile, the air in the second cylinder chamber 200 on the right side is compressed to generate high temperature, the oil injection nozzle 6 injects oil and burns to generate reverse thrust, and the partition plate 201 is pushed to rotate towards the built-in valve seat 3 on the left side, so that the 'working stroke' is realized.
At this time, the linked exhaust valve 501 in the right internal valve seat 3 is closed, the linked exhaust valve 501 in the left internal valve seat 3 is opened, the exhaust gas generated by combustion in the first cylinder chamber 100 is discharged out of the first cylinder chamber 100 through the linked exhaust valve 501 under the self-pressure and the pushing action of the partition 201, and when the partition 201 rotates to the left internal valve seat 3, the linked exhaust valve 501 therein is closed, and the first cylinder chamber 100 completes the "exhaust stroke".
The first cylinder chamber 100 continues the next working cycle: the partition 201 rotates from the left built-in valve seat 3 to the right built-in valve seat 3, and the exhaust is instantaneously completed because the pressure after combustion is high, the pressure in the first cylinder chamber 100 is lower than the atmospheric pressure, the intake valve 401 in the left built-in valve seat 3 is automatically opened, the linked exhaust valve 501 is closed, and the intake air is introduced into the first cylinder chamber 100, thereby realizing the "intake stroke" of the next cycle. In this process, the coordinated exhaust valve 501 in the right built-in valve seat 3 is opened and the second cylinder chamber 200 performs an "exhaust stroke", by which point the second cylinder chamber 200 also completes a work cycle.
The utility model discloses a twelve-cylinder arc motion rotary engine, every turn round of bent axle, every cylinder work is once in the twelve-cylinder, accomplishes a duty cycle, and the bent axle is every to rotate ninety degrees and all has non-adjacent three cylinder at the work, and this three cylinder begins the work with its adjacent three cylinder when the work is ended, can guarantee power take off's continuity and smoothness.
