Description

Description book rotary engine technology

[0001] The present invention relates to an engine, and more particularly to a rotary engine. Background technique

[0002] Conventional engines are mostly reciprocating engines. Due to the inherent structure of connecting rods, crankshafts, valves, etc., they have the disadvantages of complex structure and low thermal efficiency. At present, many rotary engine designs attempt to change this situation, such as representative Wankel's rotary piston engine. However, the design of these existing rotary engines is not reasonable, and the reciprocating or oscillating shadow can still be found in the design. The fuel consumption rate is higher than that of the reciprocating engine, which wastes fuel and pollutes the environment.

[0003] These will lead to disadvantages such as complicated structure, low efficiency, or difficult processing. Summary of the invention

[0004] It is an object of the invention to provide a new type of rotary engine that performs better than existing engines.

[0005] The present invention mainly consists of a cylinder block, a piston, a cylinder head and a gear shaft, a gear, an intake valve, an exhaust valve, an air reservoir, a spark plug, a combustion plug, a fuel injector, and a sealing strip. The arrangement of the present invention is various, as shown in Fig. 1, Fig. 5, and Fig. 6. - Now take one of them as an example to illustrate Figure 1.

[0006] The cylinder block of the engine is elliptical 1, the cylinder block has cylinder heads 2 and 3 at both ends, and a partition 4 is arranged in the middle of the cylinder block, and the cylinder cavity is divided into two (approximate) semicircular working chambers 5 and 6. A gear shaft 7 and a gear shaft 8 are respectively mounted on the symmetrical center lines of the two semicircular cavities, and the two ends of the two shafts are respectively supported on the cylinder heads 2 and 3, and the shaft is provided with an ellipse meshing with the shaft. The ring gear pistons 9 and 10 respectively divide the semicircular working chamber into two independent working chambers 5A, 5B and 6A, 6B. Two identical gear shafts are fitted with the same gears on the outside of the cylinder head to achieve simultaneous rotation of the two shafts.

[0007] It is assumed that the shaft 7 rotates clockwise and the shaft 8 rotates counterclockwise. When the piston 9 rotates 180 ° clockwise, the suction is completed in the 5A chamber, and the exhaust is completed in the 5B chamber, while the piston 10 is rotated 180° counterclockwise to complete the work in the 6A chamber, and the compression is completed in the 6B chamber. The two pistons and the two shafts rotate synchronously, and at this time, the piston 9 and the piston 10 are rotated back to the starting point by inertia to continue the rotation. When the piston 9 is rotated 180 ° again, the suction is completed in the 5A chamber, and the compression is completed in the 5B chamber, while the piston 10 is rotated 180° again. The work is completed in the 6A chamber, and the exhaust is completed in the 6B chamber. The piston 9 and the piston 10 return to the starting point for the third rotation under the inertia. When the piston 9 rotates 180°, the work is completed in the 5A chamber, and the compression is completed in the 5B chamber; when the piston 10 rotates 180°, the suction is completed in the 6A chamber. Gas, exhaust in the 6B cavity. When the piston 9 and the piston 10 are driven by inertia, they return to the starting point. After the piston 9 rotates 180 ° for the fourth time, the work is completed in the 5A chamber, the exhaust is completed in the 5B chamber, the piston 10 is rotated 180 °, the suction is completed in the 6A chamber, and the compression is completed in the 6B chamber. Such a complete work cycle is completed.

[0008] Say

[0009] It can be seen from the above table that 5A and 6A are combustion chambers, and are also suction chambers. The partitions 4 between 5A and 6A are provided with inlet and spark plugs, and the combustion chambers are along 5A and 6A. The working state is opened and closed; 5B and 6B are compression and exhaust chambers, and an exhaust valve and an air reservoir are disposed on the partition 4 between 5B and 6B, and are opened and closed according to the working states of the books 5B and 6B.

[0010] The rotary engine has compact structure, few components, small volume, light weight, good sealing performance, high work efficiency and convenient maintenance. The engine can be made by changing the intake and exhaust structure, and it can also be made into a fluid power machine such as a liquid pump, a hydraulic motor, or an air compressor.
