Description

Cage engine TECHNICAL FIELD

[0001] The present application relates to the technical field of internal combustion engines, and particularly relates to a cage engine. BACKGROUND

[0002] The prior art internal combustion engine is mainly piston and jet, and the piston and impeller are used for doing work and outputting kinetic energy in the structure of the two internal combustion engines. The piston type internal combustion engine mainly sets a cylinder in a solid cylinder body, and a piston seals one end of the cylinder. When the fuel in the cylinder is combusted to generate expanding gas, the piston is pushed to reciprocate along the inner wall of the cylinder, and the reciprocation is converted into rotation of a gear through a rocker. In this process, in order to ensure that the piston effectively transmits energy, a piston ring is arranged between the piston and the inner wall of the cylinder, and the friction between the piston ring and the inner wall of the cylinder consumes energy and is also easy to damage. Such an internal combustion engine needs a heavy cylinder body to ensure that the cylinder can maintain internal pressure, and only the reciprocating movement of the piston is used for doing work outside, and the rest is used for maintaining pressure, for setting a nozzle for supplying fuel and a spark plug for ignition, for setting an inlet and outlet valve, and the like, and does not do work outside. Therefore, the structure is complex, the weight is large, the work efficiency is low, the use is affected, and the piston and the impeller only account for a small part of the components of the whole internal combustion engine. The rest of the components are used to form a combustion chamber and the like for normal work of the piston and the impeller. Therefore, the internal combustion engine has a very complex structure, a large weight and a large volume. For example, the weight of an engine of a small car accounts for almost half of the weight of the whole vehicle. Therefore, some improvement technologies are generated, and related applications such as (publication number CN1847664A radial flow cascade compressor), (publication number CN2895787Y rotary shaft air supply rotor engine), (publication number CN102434215A external rotor fluid power machine), (publication number GB1205632A radial outflow steam turbine with integrated condenser), (CN104929691A multifunctional fluid engine) and the like are all structures for converting fluid into mechanical kinetic energy by using radial blades. The name is engine, but the engine itself does not generate energy-carrying fluid. Other devices are needed to generate and provide the fluid to the conversion structure. It is not an actual internal combustion engine. How to generate and transmit high-pressure and high-speed fluid used for doing work to the structure needs to be further provided and improved. The patent application (CN2906079Y internal combustion jet rotor engine) provides an engine. A ignition system and a fuel supply system are arranged in the engine. After the fuel is ignited and combusted, high-pressure and high-speed gas can be ejected outward. The structure of the fluid conversion into mechanical kinetic energy also adopts the radial blade (stator and rotor) structure similar to the above-mentioned applications. Compared with the axial blade structure of the piston structure and the turbine, the radial blade structure can obtain greater torque and reduce the volume. However, the blade root is subjected to a large force and cannot be long. (This problem also exists in the axial blade structure of the prior art) At the same time, the blade root needs a disc-shaped structure strong enough to install and fix the radial blade, which also increases the overall volume and weight. This part of technology needs to be improved.In addition, the patent application (CN2906079Y internal combustion injection rotor engine) still adopts the working principle of the existing piston internal combustion engine in the fuel ignition combustion working principle, that is, "the injection cavity and the combustion cavity are spatially staggered," "the utility model simulates the structure of an electric motor, combines the principles of a piston internal combustion engine and a jet engine," "the number of injection cavities and combustion chambers of the turbine rotor is different in design, thereby forming a different synchronization between the injection cavities and the combustion chambers in space, and creating an opportunity for fuel injection and ignition for the combustion chamber." "The ignition system and the pump body assembly include an ignition position sensing device," and other structures. Although this structure eliminates the reciprocating motion of the piston of the piston engine and completely rotates in one direction, eliminating the inertial loss caused by the reciprocating motion of the piston, and eliminating the structure of the valve, the efficiency is greatly improved. However, its structure needs to be controlled by a computer, and needs to be based on the requirements of the rotor speed and torque, that is, a precise ignition control system is required. The opportunity to create fuel injection and ignition for the combustion chamber is the same principle as the piston internal combustion engine, that is, the number of injection cavities and combustion chambers of the turbine rotor is different in design, thereby forming a different synchronization between the injection cavities and the combustion chambers in space, and forming the opening or closing between certain injection cavities and combustion chambers. Therefore, ignition must be performed at the appropriate time, otherwise it will cause the same problems as the piston internal combustion engine due to inaccurate ignition timing, resulting in low efficiency and even damage to the engine. Therefore, it is necessary to set up an ignition system and a fuel injection system in each combustion chamber, so this part of the technology needs to be improved. Technical solutions

[0026] The cage-type engine can be manufactured by sequentially inserting the innermost cage-type cylinder block into the rotating shaft. The cage-type cylinder block can be formed by CNC machining of a sphere with a certain thickness, including blade forming, blade rib forming, and holes for rotating shaft mounting.

During the actual mass production and use of the cage engine, only the temperature detection on the outside of the cage engine can be performed, such as using an infrared laser temperature sensor arranged on the base to detect the temperature outside the cage engine, without detecting the temperature in the harsh environment of high temperature and high pressure inside the cage engine.

[0036] The cage engine is provided with an ECU controller, which is electrically connected to the combustion-supporting agent temperature sensor, the combustion-supporting agent pressure sensor, the oxygen sensor, the throttle opening sensor and the engine temperature sensor arranged in the combustion-supporting agent channel.

There are many variations in existing technologies, which will not be described here. Those skilled in the art can understand and implement them according to the principle.

[0039] In addition to using the connection and arrangement technology provided in this application, which is different from the existing technology, the connection and control of the igniter, fuel nozzle and combustion-supporting agent of the cage engine can be realized by referring to the existing internal combustion engine technology, such as the fixation and working arrangement of the igniter and fuel nozzle with the rotating shaft, which can be realized by referring to the fixation and working arrangement of the igniter and fuel nozzle with the cylinder of the existing internal combustion engine.

[0040] The engine setting shell has the advantages of protection and support, and the reaction force generated by the resistance to the internal jet, which is the conventional setting of the prior art engine, but it also increases the weight, and the resistance problem of the internal jet needing to be discharged to the outside through a specific passage of the shell, especially in the field of aerospace, the power-to-weight ratio of the engine is particularly important and needs to be prioritized, and often needs to be set to sacrifice part of the efficiency of the engine to ensure the highest power-to-weight ratio, for example, the jet engine in the prior art, which has lower working efficiency than the piston engine, but its power-to-weight ratio is much higher than that of the piston engine, so it is applied to air passenger planes, fighter planes, etc. The working efficiency of the embodiment of the technical scheme provided in the application is different from that of the embodiment with the shell structure according to the specific environment, but the shell structure is particularly suitable for the field of aerospace, and the finally ejected gas has a higher speed due to the absence of the shell, and can generate a certain working power and improve the overall engine efficiency.

[0041] The beneficial effects of the present application are that the cage engine has the following advantages: the prior art engine with radial and axial arrangement of impellers only discharges working fluid in one direction, and the other directions and parts are used to maintain structural sealing, so the output energy is concentrated, and the material and processing technology requirements for pistons and impeller blades are very high. The cage cylinder is adopted in the present application to maximize the area of the working part in the entire engine body, so that the gas fluid ejected from the inside can act on almost the entire cage cylinder except a small area near the shaft to drive the cage cylinder to rotate, and the force is dispersed to the engine parts, thereby greatly reducing the material and processing technology requirements for the engine parts, facilitating processing and production, and reducing costs.

[0042] Further, the prior art can increase the length of the blades to improve efficiency and power, but the radial or axial blades of the prior art are subjected to the force of the gas acting vertically on their surfaces, and the requirement for the blade root to withstand the tangential force is greatly increased with the increase in the length of the blades, which limits the use requirements. The blade structure of the cage engine provided in the present application is in the shape of a circular arc, and the blade itself is both a power conversion device and a cylinder device. When the high-pressure gas in the cage engine expands outward, it is converted into a pulling force at the root of the blade near the shaft. In the case of using conventional materials, it can withstand more force than the radial or axial blades of the prior art, and it can also be made lighter and thinner, reducing the weight of the engine and improving the instantaneous performance and explosive force of the engine.

[0043] Further, the technical scheme of the present application greatly reduces the use of components compared with the prior art, has a simple structure, is more reliable, and is easy to maintain.

[0044] Further, the technical scheme of the present application greatly reduces the weight of the engine due to the increase in working area and the substantial reduction in components, improves the power-to-weight ratio of the engine, and can work uninterruptedly using the earth's atmosphere and outer space, especially suitable for aerospace.

[0045] Further, the technical scheme of the present application adopts a one-way valve structure for air intake and / or air outlet, overcoming the complex mechanical structure of the existing piston engine intake valve and exhaust valve, and the complex mechanical structure of the existing jet engine with multiple turbine blade auxiliary air intake, and is more simple and durable because there is no moving part.

[0046] Further, the technical scheme of the present application does not need piston sealing, does not use lubricating oil and its circulation system, and does not have a fixed stroke limit for the piston, so it is suitable for various combustion states without worrying about the hazards of knock, etc., on the contrary, the more intense the internal combustion of the engine of the present application, the higher the power and efficiency, and the fuel requirement is extremely low, and the applicable fuel includes combustible gas, liquid fuel and solid powder fuel, i.e. gas phase, liquid phase and solid phase fuel.

[0047] Further, in the structure of the technical scheme of the present application, the multi-layer structure of the cage engine is collectively transmitted outward by setting different shaft and cage body connection schemes and internal shaft setting schemes.

[0048] Jet engines have both constant pressure combustion and constant volume combustion, and the constant volume combustion is more efficient, the cage engine of the present application belongs to the constant volume combustion engine, if it works in the way of deflagration, combined with the above advantages, the advantages of the present technical scheme can be better played.
