Description

Linear reciprocating four-stroke bow i-Qing's compound cycle power system

The present invention relates to a recirculating power system of a linear reciprocating four-stroke engine, and more particularly to a new engine system that saves energy, increases efficiency, is small in size, and is relatively easy to maintain. Background technique

Since the industrial revolution, human beings have become more and more demanding for energy, which has greatly increased the exploitation of various natural resources such as oil, natural gas and coal. Although these behaviors have greatly improved the quality of life of human beings, they have caused it to be difficult to recover from the earth. In particular, the earth's resources are bound to be limited, but human needs for energy are infinite. After the exploitation of natural resources, human life will eventually return to the original, which is unacceptable to most humans. fact.

Therefore, countries do not focus on the development of new energy, especially environmental energy research. These include the use of historic hydropower, wind power, and the recent popularity of solar energy, all of which are good energy for future needs. However, the aforementioned energy use efficiency is far less than the traditional fuel method. Although the future is promising, it cannot be effectively utilized in the short term. It is very likely that the traditional energy generation method cannot be completely replaced before the oil consumption is completed.

Therefore, only by saving energy can we ensure that the quality of human life is maintained to meet the arrival of energy in the new era. The inventor of this case upholds this belief and accumulates the engine's power operation method to reduce unnecessary losses and increase the energy efficiency of fuel generation.

As far as current engine technology is concerned, the kinetic energy generated by its fuel loss is far from the theoretical value. Even a more efficient four-stroke engine will waste a lot of resources. The reason for the loss may be due to various factors such as incomplete combustion, mechanical consumption, and heat consumption. These factors may not be solved at one time, but require long-term research and development. However, some design problems should be solved immediately. We know that the power of the four-stroke engine must pass through the process of intake, compression, explosion, and exhaust, and then convert the linear motion of the cylinder into a rotary motion through a crankshaft, thereby driving the gearbox to transmit. When the power is transmitted through the crankshaft, due to the change of direction, some of the power will be lost due to the lateral component force transmitted to the outside, and the ratio of these power losses will change at any time due to the rotation angle of the crankshaft, resulting in the traditional engine. The power is reduced and unstable.

In addition, the four-stroke engine only explodes once after two revolutions of the crankshaft. Although the mixing and combustion are relatively complete, it is environmentally friendly, but the power output efficiency is further reduced. Therefore, the four-stroke engine needs to achieve a large horsepower. Only by increasing the cylinder capacity or increasing the number of cylinders, the energy consumption is even more alarming. The crankshaft itself also increases the size of the engine, making it take up space.

In addition, engine waste heat is generated when the engine is running. These waste heat is also a loss of energy. If it can be effectively utilized, it will be an effective method to improve engine efficiency.

It can be seen that there is still much room for improvement in the well-known engine technology, and the industry is actively researching and improving it.

In view of the lack of the above-mentioned known structure in actual use, the inventor of the present invention conceived to maintain the power output in the reciprocating motion mode of the piston, avoid the loss of the lateral component force, maintain the stability of the power, and effectively reduce the engine waste heat. Reuse. Through long-term research and development and implementation, as well as years of experience in the development of relevant industry development practices, we have finally developed a recirculating power system for this linear reciprocating four-stroke engine. Summary of the invention

The main object of the present invention is to provide a recirculating power system of a linear reciprocating four-stroke engine, wherein the power output strokes are all linear reciprocating motions, so that the cylinder generating power can be completely outputted, reducing losses and improving engine performance.

Another object of the present invention is to provide a recirculating power system of a linear reciprocating four-stroke engine, which adopts multiple sets of cylinder configuration modes, and each group of cylinders can adjust the stroke according to the situation, and even partially stop and rest, and only maintain part of the movement, Enable the entire engine system to maintain effective operation for a long time, It can also reduce the loss accident caused by overheating. Since no crankshaft is required, even if multiple cylinders are configured, it does not add much volume.

It is still another object of the present invention to provide a recirculating power system for a linear reciprocating four-stroke engine that further collects residual heat generated by engine operation and reuses it to improve engine output performance.

The above object of the present invention can be achieved by the following technical solution, a recirculating power system of a linear reciprocating four-stroke engine, comprising a reciprocating cylinder group and a transmission shaft, each of the reciprocating cylinder groups being provided with two cylinders, The cylinder has a piston that pushes a piston rod to move, and the two cylinders are oppositely disposed. The piston rods of the two cylinders are integrated and linearly moved back and forth between the two cylinders, and the piston rod has upper and lower racks. The transmission shaft is disposed between the upper and lower racks, and the surface of the transmission shaft is matched with the upper and lower racks with a quarter-outer tooth belt of the circumference of the transmission shaft, so that the tooth belt can only be used at any time. One of the upper and lower racks is engaged. Thus, when the upper rack is moved by the explosive stroke, the drive shaft can be engaged to rotate, and when the tooth strip is disengaged from the upper rack, the lower rack just enters the explosion stroke and the meshing drive shaft continues to rotate. The cylinder has an exhaust port connected to a double cycle cylinder, the exhaust end of the double cycle cylinder is provided with a rotating blade, and the double cycle cylinder has water storage, and the water storage will reciprocate The high-heat exhaust gas discharged from the cylinder group is rapidly expanded into a high-pressure water stream or water vapor to generate kinetic energy by impacting the rotation of the rotating blade. For example, with a hydrogen engine, the exhaust gas temperature can be as high as 2,000 °C, which is optimal. Reuse, forming a complex cycle power system. DRAWINGS

1 and 2 show a recirculating power system of a linear reciprocating four-stroke engine, which includes a reciprocating cylinder group 1 and a transmission shaft 2. The reciprocating cylinder group 1 is configured in at least two groups, and each group of reciprocating cylinder groups 1 is provided with two cylinders 11 to form four cylinders 11 to match the intake, compression, explosion, and exhaust strokes of the four-stroke engine. The cylinder has a piston 3 which urges a piston rod 4 to move, and the two cylinders 11 are disposed oppositely, and the piston rods 4 of the two cylinders 11 are integrated and linearly moved back and forth between the two cylinders 11.

The piston rod 4 has upper and lower racks 41, 42, and the transmission shaft 2 is disposed between the upper and lower racks 41, 42. The surface of the transmission shaft 2 is matched with the upper and lower racks 41, 42. 21, the toothed belt 21 occupies only a quarter of the outer diameter of the circumference of the transmission shaft 2, the purpose of which is to enable the toothed belt 21 to engage only one of the upper and lower racks 41, 42 at any time, that is, the present When the rack 42 is moved by the explosion stroke, the drive shaft 2 can be engaged to rotate; and when the tooth belt 21 is disengaged from the lower rack 42, the upper rack 41 just enters the explosion stroke and the meshing drive shaft 2 continues to rotate. Therefore, the present invention eliminates the need for a complicated mechanical structure such as a ratchet, that is, maintains the drive shaft 2 to continuously rotate in the same direction, and maintains a stable power output.

Therefore, the operation mode thereof will be described with reference to FIG. 1, which is provided with four cylinders A, B, C, and D. When the cylinder A enters the explosion stroke, its power is maximum, so the gear shaft 2 is meshed through the lower rack 42. The row rotates while pushing the cylinder B to compress; ⁵ At this time, the cylinder C starts the intake stroke at the same time, so the synchronization and the transmission shaft 2 move without interfering, and the cylinder D enters the exhaust stroke. Then, each cylinder A, B, C, D simultaneously performs the next stroke, and meshes with the transmission shaft 2 via the upper rack 41 to continue the rotation. Therefore, the present invention can configure the most cylinders 11 in a limited space to increase power efficiency.

According to the foregoing structure, the cylinder 11 has an exhaust port 12 that is connected to a recirculation cylinder 5, and the exhaust end of the recirculation cylinder 5 is provided with a rotary vane 6 in which the recirculation cylinder 5 is disposed. There is a water storage 51 (fresh water) having an axis 52 therein. In the case of the double cycle cylinder E, when the cylinder B is exhausted, its exhaust entrains waste heat into the double cycle cylinder E. As shown in the double cycle cylinder F, when the exhaust stroke is completed, the shaft 52 in the double cycle cylinder F is pushed down to mix the high heat exhaust gas with the water storage 51 and rapidly expand into a high pressure water flow or water vapor. Then, the shaft 52 in the double-cycle cylinder F is pushed to be guided to the rotating blade 6 to impact the rotation of the rotating blade 6 to generate kinetic energy, and the rotating blade 6 can drive the generator to generate electricity, and effectively use the energy. .

Referring to FIG. 2, in actual application, the present invention can be used in two or three sets of engines. When the first engine 71 is overheated, the second engine 72 can be used to continue working, and the first engine 71 is rested; when the second engine 72 is overheated, the third engine 73 is switched to continue working. Therefore, multiple sets of engines 71, 72, and 73 can make the system run smoothly, drive a generator 8 to generate electricity, and because the crankshaft design of the conventional engine is not required, the number of engines is increased, but the excess volume is not increased.

The above is a specific description of a possible embodiment of the present invention, and the embodiment is not intended to limit the scope of the invention, and the equivalent implementation or modification of the present invention should be included in the patent of the present invention. In the scope.
