Detailed Implementation

[0047] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1

[0049] Please see Figure 1 - Figure 5 This application provides a diesel rotary engine, comprising:

[0050] An engine housing 100 has a combustion chamber inside it, and an exhaust port 103 is provided on the side of the combustion chamber.

[0051] A circulating cooling mechanism 200, installed on the outer surface of the engine housing 100, utilizes the exhaust gas from the engine. By providing this circulating cooling mechanism 200, the exhaust gas is collected and cooled by the piston cylinder 201 and cooling cylinder 203. The cooled exhaust gas first enters the internal cooling passage 205, where the flowing cooled exhaust gas provides internal cooling to the engine. Simultaneously, the exhaust gas entering the piston cylinder 201 drives the piston plate 2012 to move back and forth, simultaneously drawing in outside air for cooling. This cooled air then acts on the outer surface of the engine housing 100 for external cooling. This multiple circulation improves the cooling effect. Furthermore, the internally cooled exhaust gas is reused in the engine intake system. The circulating cooling mechanism 200 includes:

[0052] The piston cylinder 201 is installed on the outer surface of the engine housing 100 and aligned with the exhaust port 103. The overall structure of the piston cylinder 201 integrates functions such as exhaust gas drive, air cooling, and airflow delivery. It does not require additional power to drive the piston plate 2012 to move, making full use of the energy of the exhaust gas itself, thus achieving the purpose of energy saving and consumption reduction. The exhaust port 103 is coaxially aligned with the piston cylinder 201, and the piston plate 2012 that can move back and forth is provided inside the piston cylinder 201.

[0053] Multiple internal cooling channels 205 are opened inside the engine housing 100. The inner diameter of the channels is reasonably designed according to the thickness of the housing and the heat exchange requirements to ensure that the exhaust gas flow speed is moderate, so as to achieve sufficient heat exchange without generating excessive resistance.

[0054] Cooling cylinder 203 installed above piston cylinder 201 to cool the exhaust gas;

[0055] A circulating internal cooling component 202 is installed on the outside of the engine housing 100 and communicates with the internal cooling passage 205. The piston cylinder 201 sends the cooled exhaust gas into the circulating internal cooling component 202.

[0056] An external cooling component 204 is installed on the outside of the engine housing 100 to cool the outer surface of the engine housing 100. The external cooling component 204 is connected to the piston cylinder 201.

[0057] In this embodiment, preferably, the piston cylinder 201 for cooling the air entering the piston cylinder 201 includes:

[0058] An internal piston plate 2012 is provided, and an internal cooling plate 2013 is provided on the rear surface of the piston plate 2012. A cooling chamber is formed between the internal cooling plate 2013 and the rear end of the piston cylinder 201.

[0059] Two bellows 2033 are installed on the rear surface of the inner cooling plate 2013 and the inner surface of the rear end of the piston cylinder 201. The bellows 2033 can be unfolded or folded.

[0060] The exhaust pipes 2011 are installed on both sides of the front end of the piston cylinder 201 and are connected to the circulating internal cooling component 202.

[0061] In this embodiment, preferably, a connector 2018 is provided on the rear surface of the inner cooling plate 2013, and a valve 2019 is provided on the connector 2018. The application of the valve 2019 realizes the precise control of the airflow channel opening and closing, ensuring the orderly progress of the entire gas circulation process. An L-shaped air passage 20110 is opened inside the piston plate 2012 and the inner cooling plate 2013.

[0062] In this embodiment, preferably, the circulating internal cooling component 202 for circulating cooling within the engine housing 100 includes:

[0063] The rear air distribution pipe 2021 is located behind the engine housing 100. The shape and size of the rear air distribution pipe 2021 and the front collection distribution pipe 2023 are matched with the engine housing 100 and fixed by stainless steel brackets. The front surface of the rear air distribution pipe 2021 is provided with an air supply branch pipe 2022 that communicates with the rear end of the internal cooling channel 205. The number of air supply branch pipes 2022 and collection branch pipes 2024 matches the number of internal cooling channels 205.

[0064] A front collection and distribution pipe 2023 is located in front of the engine housing 100. A collection branch pipe 2024 communicating with the front end of the internal cooling channel 205 is provided on the rear surface of the front collection and distribution pipe 2023. An air supply pipe 2025 is connected to the side of the collection branch pipe 2024.

[0065] The main air pipe 2026 is connected to the rear air distribution pipe 2021. A T-shaped pipe 2015 is provided between the other end of the main air pipe 2026 and the exhaust pipe 2011 to facilitate control of the flow direction of the exhaust gas.

[0066] In summary, during use, the piston plate 2012 is initially positioned at the front end of the piston cylinder 201. At this time, the piston plate 2012 is located in front of the primary intake pipe 304, and the bellows 2033, connector 2018, air passage 20110, and exhaust pipe 2011 are connected. However, valve 20111 on the exhaust pipe 2011 is closed, while the valve on the primary intake pipe 304 is closed, and the valve on the U-shaped pipe 2041 is open. The internal cooling plate 2013 is activated, storing cooled air between the rear surface of the internal cooling plate 2013 and the piston cylinder 201. The combustion exhaust gas from the engine enters the piston cylinder 201, and the impact force pushes the piston plate 2012 backward. The bellows 2033 gradually folds, and the piston plate 2012... The material can withstand the high temperature of the exhaust gas. When the piston plate 2012 moves backward and is located behind the primary intake pipe 304, the valve on the primary intake pipe 304 opens, and the exhaust gas enters the cooling cylinder 203 through the primary intake pipe 304. It is cooled and filtered by the cooling component 300 to remove particles from the exhaust gas. The filtered and cooled exhaust gas enters the pressurization pipe 2031 (at this time, valve 1 2016 and valve 2 2017 are closed). The pressurization pipe 2031 is connected to an external pressurization pump, which applies pressure, causing the exhaust gas to enter the connecting pipe 2032 and then the bellows 2033. The bellows 2033 is located in the cooling chamber and is cooled and carries the low temperature. The exhaust gas enters the bellows 2033 and can pass through the bellows 2033. 3. As the temperature drops again, the incoming exhaust gas gradually increases, pushing the bellows 2033 to gradually unfold and move forward from behind the piston plate 2012. When the piston plate 2012 is in front of the primary intake pipe 304, the valve on it closes again. When the piston plate 2012 moves forward to its initial position, valve four 20111 on the exhaust pipe 2011 opens, connecting the bellows 2033, connector 2018, air passage 20110, and exhaust pipe 2011. Exhaust gas enters the exhaust pipe 2011. If the exhaust gas temperature drops sufficiently, valve one 2016 can be opened and valve two 2017 closed, allowing the exhaust gas to directly enter the main air pipe 2026, and then the rear air distribution pipe 2021, passing through multiple air supply branches. Pipe 2022 enters the internal cooling channel 205 and flows forward along the length of the internal cooling channel 205 to cool the inside of the engine casing 100. The exhaust gas flows forward and enters the front collection and distribution pipe 2023, and finally enters the engine intake system through the air supply pipe 2025 to achieve internal cooling of the engine and improve engine cooling efficiency. At the same time, the exhaust gas can be cooled and then sent back into the air supply system for reuse, improving exhaust gas utilization. If the temperature of the exhaust gas is not sufficiently cooled, valve 1 2016 can be closed and valve 2 2017 can be opened, and the exhaust gas can re-enter the cooling cylinder 203 and piston cylinder 201 for cooling, extending the exhaust gas cooling time and facilitating the subsequent exhaust gas to reach the temperature required to enter the intake system.

[0067] Example 2

[0068] Based on Example 1, refer to Figure 4 - Figure 7 This is the second embodiment of the present invention.

[0069] In this embodiment, preferably, a primary air inlet pipe 304 is provided between the cooling cylinder 203 and the piston cylinder 201, a pressurizing pipe 2031 is provided at the upper end of the cooling cylinder 203, and a connecting pipe 2032 is provided at the lower end of the pressurizing pipe 2031, which passes through the piston cylinder 201 and connects to the bellows 2033.

[0070] In this embodiment, preferably, by providing an external cooling component 204, the external components of the engine can be cooled without conflicting with the engine's own operation and exhaust gas utilization. Combined with internal cooling, this forms a multi-cooling method, improving the engine's heat dissipation efficiency and keeping it at a relatively suitable operating temperature. The external cooling component 204, which cools the outer surface of the engine casing 100, includes:

[0071] An arc-shaped pipe 2043 is located on the outer side of the middle part of the engine housing 100. An extension branch pipe 2044 is provided on the side of the arc-shaped pipe 2043. The extension branch pipe 2044 is distributed along the axial direction of the engine housing 100 and covers the main heat-generating area of ​​the housing. Each extension branch pipe 2044 is equipped with an independent control valve, which can adjust the air flow according to the temperature of different areas of the housing. An air outlet 2045 is opened on the surface of the extension branch pipe 2044.

[0072] A U-shaped tube 2041 is installed on the rear surface of the two piston cylinders 201, and the U-shaped tube 2041 is located below the connecting tube 2032;

[0073] Connecting pipe 2042 is installed between U-shaped pipe 2041 and arc-shaped pipe 2043.

[0074] In summary, during operation, the initial cooling chamber of the piston cylinder 201 retains air. When the piston plate 2012 moves backward due to the impact of combustion exhaust gas, it forces the air in the cooling chamber into the U-shaped pipe 2041 and connecting pipe 2042, and then into the arc-shaped pipe 2043. From there, the air is distributed to multiple extension pipes 2044. Valves can be installed on the extension pipes 2044, and the number of valves can be set as needed. Finally, the air is discharged from the outlet 2045 on the extension pipes 2044, acting on the outer surface of the engine housing 100 to cool the exterior of the engine housing 100. The number and distribution of the extension pipes 2044 can be set as needed. During the forward resetting process of the piston plate 2012, the cooling chamber space gradually increases, and air can be drawn in reverse using the outlet 2045 to be sent back into the cooling chamber for further cooling, facilitating the next cooling of the exterior of the engine housing 100. Combined with the internal cooling of the engine, this creates a simultaneous cooling effect on both the interior and exterior of the engine, keeping the engine at a suitable operating temperature.

[0075] Example 3

[0076] Based on Example 2, refer to Figure 1 , Figure 5 and Figure 8 This is the third embodiment of the present invention.

[0077] In this embodiment, preferably, the cooling cylinder 203 is provided with a cooling component 300 for cooling the exhaust gas. By providing the cooling component 300, the exhaust gas entering the cooling cylinder 203 can be cooled, reducing the initial temperature of the exhaust gas and performing multi-stage filtration to eliminate large particles in the exhaust gas, thus facilitating the subsequent entry of the exhaust gas into the intake system and preventing the exhaust gas from affecting the components in the engine combustion chamber when it is reused for combustion. The cooling component 300 includes:

[0078] Multiple arc-shaped cooling plates 301 are distributed circumferentially on the inner wall of the cooling cylinder 203. The plates are made of semiconductor cooling materials, have an integrated cooling circuit, and are connected to an external power supply. They can quickly reduce the surface temperature. The surface of the plates is treated with anti-corrosion and high-temperature resistance to resist the corrosion of exhaust gas.

[0079] The stirring fan blade 305 is located above the primary air inlet pipe 304 and below the arc-shaped cooling plate 301. A circular support frame 303 is provided inside the lower end of the cooling cylinder 203. A support shaft supporting the stirring fan blade 305 is provided at the center of the circular support frame 303. The support shaft is rotatably connected to the stirring fan blade 305.

[0080] The filter assembly 302 is located above the filter assembly 302 and is used for filtering exhaust gas.

[0081] In this embodiment, preferably, the horizontal ends of the T-shaped tube 2015 are connected to the main air pipe 2026 and the cooling cylinder 203, respectively, and the horizontal ends of the T-shaped tube 2015 are respectively provided with valve 2017 and valve 1016. Valve 2017 and valve 1016 can automatically switch the airflow direction according to the exhaust gas temperature. The vertical end of the T-shaped tube 2015 is connected to the exhaust pipe 2011.

[0082] In this embodiment, preferably, multiple cooling columns 2014 are provided on the rear surface of the cooling column 2014, and the cooling column 2014 can conduct heat to facilitate sufficient cooling of the air in the cooling chamber. The length of the cooling column 2014 is matched with the folding length of the bellows 2033, so it will not affect the movement of the piston plate 2012.

[0083] In this embodiment, preferably, an eccentric shaft 101 is provided inside the engine housing 100, a triangular rotor 102 is provided on the eccentric shaft 101, and a spark plug 104 is provided on the side of the engine housing 100.

[0084] In summary, during use, exhaust gas enters the primary intake pipe 304 and impacts the agitator blades 305, causing the exhaust gas to rotate and agitate, fully contacting the distributed arc-shaped cooling plates 301 to cool the exhaust gas. The cooled exhaust gas then flows upward through the filter assembly 302. The filter assembly 302 can be a combination of various ceramic filter plates, providing multiple filtrations. The filtration principle is existing technology and will not be described in detail in this application. After filtration through the filter assembly 302, the filtered gas enters the pressurization pipe 2031 for further cooling and filtration, which facilitates its entry into the intake system and reduces the amount of particulate matter entering the combustion chamber with the intake system.

[0085] The working principle of this invention is as follows: During operation, the exhaust gas from the engine enters the piston cylinder 201. The impact force pushes the piston plate 2012 backward, and the bellows 2033 gradually folds. When the piston plate 2012 moves backward and is located behind the primary intake pipe 304, the valve on the primary intake pipe 304 opens, and the exhaust gas enters the cooling cylinder 203 for cooling through the primary intake pipe 304. The exhaust gas then enters the pressurization pipe 2031 and finally enters the bellows 2033. The piston plate 2012 is pushed forward and reset. After resetting, the exhaust gas enters the exhaust pipe 2011 and the main air pipe 2026 through the air passage 20110, then enters the rear air distribution pipe 2021, and enters the internal cooling channel 205 through multiple air branch pipes 2022, flowing forward along the length of the internal cooling channel 205. The combustion exhaust gas moves forward, cooling the interior of the engine casing 100. The exhaust gas flows forward and enters the front collection and distribution pipe 2023, eventually being sent into the engine intake system through the air supply pipe 2025. The impact force of the combustion exhaust gas pushes the piston plate 2012 backward, squeezing air from the cooling chamber into the U-shaped pipe 2041 and connecting pipe 2042, and then into the arc-shaped pipe 2043. From there, it is distributed to multiple extension pipes 2044, and finally discharged from the outlet holes 2045 on the extension pipes 2044. This cooling effect acts on the outer surface of the engine casing 100, achieving simultaneous cooling of the engine's interior and exterior, keeping the engine at a suitable operating temperature. Furthermore, the cooled exhaust gas can be easily reused in the intake system.

[0086] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
