Description

Reciprocating piston type rotor engine

One, the technical field

The invention relates to a novel internal combustion engine, and belongs to the field of power machinery.

Second, background Art

The key technical key points of the internal combustion engines widely used in the world are that a variable volume mechanism is required, a proper enough compression ratio can be generated, a thermal power cycle is completed, and work is done on external output torque, and the key core technology is the problems of the sealing between a piston and a cylinder wall in an element volume, the shape and the dynamic property of a combustion chamber, the fuel economy, the emission cleanness and other technical performance indexes. For over a hundred years, crank-connecting rod piston internal combustion engines, which have dominated internal combustion engines, have become technically very mature. In recent years, engines have entered the "electronic age" and their development has progressed almost to the perfection. However, at the same time it brings with it structural disadvantages which are difficult to overcome. The first is that the structure is complex, heavy, the number of parts is large, the precision requirement is high, and the processing and manufacturing cost is high. Secondly, the crankshaft and the piston have upper and lower dead points, so that high-speed reciprocating inertia impact vibration is generated, torsional vibration of a crankshaft shaft system is large, the damage to the engine body is large, and the damage is more and more prominent along with the improvement of the strengthening degree. Thirdly, the left and right swinging of the connecting rod in the structure inevitably causes the machine body to eat more than 40 percent of energy in the working process for the inclined strut of the piston and the crankshaft, which is the consumption of useless work, so that the heat efficiency of the machine type is inevitably low, and the 50 percent of the heat is always not broken through, in other words, the heat efficiency cannot be broken through by 50 percent as long as the piston structure of the crankshaft connecting rod is adopted, and the continuous improvement and development of the internal combustion engine are seriously hindered, thereby directly influencing the development of the world economy. Fourth, it is known that the reciprocating linear motion of the piston of the internal combustion engine in the cylinder is converted into a rotational motion by the crankshaft connecting rod transmission mechanism to output work to the outside, and the crankshaft connecting rod mechanism can convert less than 50% of the expansion force into rotational power at best during the conversion process, so that it has poor dynamic properties. Fifthly, the volume power is not high, the specific gravity is large, the large-power marine transport vehicle is particularly remarkable in the case of ultrahigh power, the maximum power of the marine transport vehicle can only reach 48000PS, the weight of the marine transport vehicle can reach 1700 tons, the vehicle is enlarged, the parts are difficult to process, install and maintain, and a single vehicle power cannot be enlarged, so that the marine transport vehicle is a great obstacle to increasingly developed marine transport industry. Sixth, the crankshaft is difficult to process, especially the multi-cylinder and high-power machine type is more prominent, and the difficulty in processing makes the crankshaft difficult to become a bottleneck technology in the manufacturing industry of the internal combustion engine.

The defects are caused by the structure of the crank-connecting rod piston engine and are difficult to overcome for a long time, and the problems are known to all people, so that a plurality of scientific research institutions, colleges and universities, military equipment institutions and thousands of expert and scholars all want to break through the structure of the traditional engine, but the defects are not successful for more than one hundred years.

Compared with the traditional crank connecting rod piston engine, the 'Wankel' triangular piston rotary engine which is gradually matured omits a heavy transmission mechanism of a crank connecting rod and a complex gas distribution mechanism and the like, has simple structure and light weight, can directly convert combustion expansion force into rotary power of a main shaft, has stable operation, small vibration and low noise, has the performance characteristics of great progress compared with the traditional crank connecting rod piston engine, but can not replace the traditional crank connecting rod piston engine. This is due to a serious drawback of its own structure. Firstly, it has high processing technical requirements, great difficulty and high manufacturing cost. Secondly, the oil consumption is large, the heat efficiency is low, and the dynamic property is poor. Thirdly, the sealing performance in the cylinder is poor, the pressure ratio is small, the combustion is insufficient, the emission performance is poor and the pollution is serious. And fourthly, the air chamber sealing device is only suitable for high-speed occasions such as light low-power plug cars, motorcycles and the like, and has the defects of reduced sealing property between air chambers and serious air leakage and smoke leakage during slow speed and idling. The requirements for the emission cleanness and the fuel economy of the engine are higher and higher all over the world at present, and in addition, the oil crisis is one wave to one wave, the oil price is high, and the harsh market rule forces the engine to be eliminated quickly.

Fourthly, beneficial effects

The invention has innovation and breakthrough on the whole structure, and carries out the replacement and reconstruction of the heart of the existing engine in a way of removing fetus and changing bones. The invention breaks through the structure of the reciprocating piston type of the crank connecting rod of the 'Otto' machine, breaks through the structure of the triangular piston rotary engine of the German Wankel doctor of the inventor of the talent, and independently creates a new machine type, so that all the defects caused by the structure of the existing engine are relieved or radically treated. The four-stroke mechanism has clear boundary line, smooth transition and stability, eliminates the upper and lower dead points of a crank-connecting rod transmission mechanism and the left and right swinging of a connecting rod, and the machine head tray drives the machine head to rotate in one direction all the time, so that two major hazards of high-speed reciprocating inertial impact vibration and torsional vibration, which are hidden dangers of equipment accidents, are thoroughly solved on the basis of the structural function principle, the old problem that scientists all over the world have headache for more than one hundred years is solved, and the service life of the machine can be effectively prolonged by removing the two vibrations. The method eliminates vibration and vibration noise pollution, is beneficial to environmental protection, is revolutionary technical innovation by replacing the traditional crank connecting rod transmission with the elliptic track groove double-T-shaped rolling connecting rod, is a technological progress which cannot be achieved, and has the greatest work that the structural principle of an internal combustion engine is liberated from the traditional Otto crank connecting rod reciprocating piston type, so that the regeneration is obtained, and the crank connecting rod reciprocating piston machine is changed into a reciprocating piston rotor machine.

The structural characteristics of the double-elliptic-track-groove double-T-shaped rolling connecting rod enable the main shaft to complete one-time four-stroke thermal power cycle working once after rotating one circle, and compared with the traditional crank connecting rod reciprocating piston engine which can complete one-time four-stroke thermal power cycle working once after rotating two circles by the main shaft, the working efficiency of the engine is improved by one time in an integral way.

The effective thermal efficiency is an important technical performance index of an engine for converting chemical energy of fuel into mechanical energy, the effective thermal efficiency of the existing engine is 20-30% of that of a gasoline engine, 30-40% of that of a diesel engine, and the highest value of a supercharged diesel engine is only 46% and is far less than 50%. Scientific technology is developed all the time, but the effective thermal efficiency of the engine cannot be improved continuously, and the 50% of the major factor cannot be broken through all the time. This is because the reciprocating piston type structure of the crank connecting rod of the current engine has limited digestion and absorption capacity in the process of function conversion, and can only convert less than 50% of energy into useful work. The rotor structure machine head cylinder is arranged in the tangential direction of the machine head tray, and can directly convert most of combustion expansion force into the rotary power of the main shaft except a small amount of heat transfer loss, so that the middle conversion link of a crankshaft is omitted, and the useless power loss caused by the left-right swinging of a connecting rod and the diagonal bracing is also eliminated. Therefore, the effective thermal efficiency of the engine can be greatly improved compared with the existing engine according to the theory, the fuel oil can be saved by more than 50%, the dynamic property can be doubled, and the engine can save energy and reduce the emission at the same time in the theory, which is a hard index determined by the structural principle.

The invention has simple structure, few parts and easy processing, removes not only a heavy crankshaft connecting rod flywheel mechanism, but also a complex gas distribution mechanism, has the number of the parts being 50 percent of that of the traditional engine with the same power, reduces the parts, and brings great benefits to the reduction of machine faults, the increase of working reliability and maintenance convenience and the reduction of manufacturing cost. The invention has few parts and is easy to process, suitable for mass production, and can be processed and manufactured in any engine plant without increasing equipment.

The invention has wide application and modification range, can be made into a gasoline rotor engine and a diesel rotor engine, can use various fuels, and has strong applicability. All advanced technologies of modern automobile engines can be grafted and checked into seats. This is also a hard technology determined by the structural principle.

And (VI) the rotating speed is high, the speed is increased quickly, and the acceleration is good. The rotor structure of the invention is very beneficial to improving the rotating speed: 1. the piston of the invention is subjected to pure straight line push-pull force in the cylinder, and does not have the connecting rod swinging left and right and inclined pull inclined strut, so the pressure to the cylinder wall is uniform all around, and deflection phenomenon does not exist, so after the speed is improved, the friction force is far not as large as that of a traditional engine, and the generated noise is lower; 2. the upper dead point and the lower dead point are not arranged and no vibration is generated in the working and running process; the machine head drives the tray and the main shaft to rotate only in one direction all the time, so that the speed is increased quickly and the acceleration is good; 3. the working efficiency is doubled; 4. the dynamic performance is doubled; 5. the invention replaces the traditional engine mushroom-shaped valve with the steam inlet reed valve steam exhaust rotary valve, which not only solves the problem that the valve inertia obstructs the air flow and the sealing problem of the air valve at high speed, but also solves the problems that the mushroom-shaped exhaust valve is easy to overheat and the sealing, lubrication, engine oil consumption and the like caused by the tempering phenomenon of the mushroom-shaped valve. The rotation speed is increased, which is very beneficial to improving the power of a single machine and speeding up transportation and military equipment. The rotor rotates in one direction all the time, and the machine head continuously and alternately works, so that the speed of the machine is high, the speed is fast, the acceleration is good, and the machine can greatly meet the modern needs of people and the needs of military skills, which is a hard technology determined by the structural principle.

And (seventhly), breaking through the ultra-high power limit. At present, the maximum value of the power of marine engines in the world is 48000PS, which is limited by the limitation that the weight is large, the weight of the 48000PS engine reaches 1700 tons, the weight is large, the manufacturing, the installation and the maintenance are difficult, in addition, the crankshaft is difficult to process, which is the bottleneck of the manufacturing of the engine with the super-high power, and in order to break through the technology, China collects the national technical power and costs billions of RMB, the power is finished in large-scale shipyards in the previous year.

The structure of the invention can easily break through the limit of high power. Compared with the traditional crank connecting rod piston engine with the same power, the weight of the invention is only half of the weight of the traditional crank connecting rod piston engine, so from the angle of the weight, the limit of 48000PS can be broken through by using the engine type of the invention, from the angle of the crankshaft processing technology, the invention does not use the crankshaft at all, the main shaft is cylindrical, the problem that more main shafts can be easily solved by using a ten thousand two thousand tons hydraulic press can be easily solved, and more importantly, the rotor structure of the invention can be connected in series in multiple stages, so that more favorable conditions are created for breaking through the 48000PS super large internal combustion engine, and the engine is a hard technology determined by the structural principle.

In conclusion, it is obvious that the invention is a new idea, a new starting point, strong innovation, novel and ingenious conception, brings out the best in combination, is scientific and reasonable, and successfully solves the structural principle of the fourth generation internal combustion engine, thereby opening up a new era of the forward development of the internal combustion engine, and leading the development of the world engine to be a new trend, so that the economic benefit and the social benefit of the invention are obvious and huge.
