Description

Technical Field

[0002] In existing pre-chamber engine technology, the fuel in the pre-chamber is typically ignited by arc discharge from a spark plug located within the pre-chamber. The resulting high-temperature jet of free radicals ignites the fuel in the main combustion chamber, achieving engine ignition. However, in spark ignition mode, combustion in the pre-chamber develops locally and then throughout the entire pre-chamber space. The jet takes time to develop, and the flame propagates slowly. Furthermore, the size limitations of components such as the spark plug make miniaturization of the pre-chamber difficult. Summary of the Invention

[0003] The present invention aims to address at least one of the technical problems existing in the prior art. To this end, the present invention provides an ignition component that, through a catalytic layer, reduces the temperature required to ignite the fuel, shortens the flame propagation process in the heating device, increases the combustion rate, and strengthens the jet intensity of the airflow ejected from the pre-combustion chamber, thereby improving the ignition efficiency of the ignition component.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0045] The following describes an ignition component 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0046] like Figure 1 and Figure 2 As shown, the ignition component 1 according to the embodiment of the present invention includes a housing 11 and a heating device 12 .

[0047] The shell 11 has a pre-combustion chamber 111 , the inner wall of the pre-combustion chamber 111 has a catalytic layer 1111 , the catalytic layer 1111 is used to catalyze the combustion of fuel in the pre-combustion chamber 111 , and the heating device 12 is used to heat the fuel in the pre-combustion chamber 111 .

[0048] It can be understood that when the fuel in the precombustion chamber 111 needs to be burned, the fuel in the precombustion chamber 111 is heated by the heating device 12 to achieve fuel combustion. Then, the high-temperature and high-pressure gas generated by the fuel combustion can be injected from the injection hole 113 of the shell 11 to the external environment of the shell 11 to ignite the fuel in the environment where the shell 11 is located.

[0049] Compared with the prior art, the present application eliminates the spark plug and heats the fuel in the pre-combustion chamber 111 through the heating device 12 to realize the combustion of the fuel, shorten the flame propagation process, and increase the combustion rate, thereby enhancing the jet intensity of the airflow ejected from the pre-combustion chamber 111. At the same time, the size of the shell 11 of the present application is not limited by the spark plug structure, making it possible to further miniaturize the pre-combustion chamber 111, further shortening the flame propagation process of the mixture in the pre-combustion chamber 111, and even eliminating the need for a flame propagation process. Shells 11 of different sizes can be designed as needed to improve the versatility of the ignition component 1.

[0050] For example, when the volume of the precombustion chamber 111 is large, the heating device 12 heats the fuel in the precombustion chamber 111 to realize the combustion and propagation of the fuel, so that the high-temperature and high-pressure gas can be ejected from the injection hole 113 of the shell 11 to the external environment of the shell 11, effectively shortening the flame propagation process; or, when the volume of the precombustion chamber 111 is small, the heating device 12 heats the fuel in the precombustion chamber 111, causing the pressure to rise sharply, producing an explosion-like phenomenon, and instantly releasing energy so that the airflow forms a higher-speed jet and is ejected from the injection hole 113 of the shell 11 to the external environment of the shell 11.

[0051] The inner wall of the precombustion chamber 111 has a catalytic layer 1111. In the process of the heating device 12 heating the fuel in the precombustion chamber 111, the catalytic layer 1111 catalyzes the combustion of the fuel in the precombustion chamber 111. The heating device 12 can heat the fuel to 0.7 times to 0.9 times the auto-ignition temperature of the fuel to achieve combustion of the fuel, thereby reducing the temperature required to ignite the fuel through the catalytic layer 1111, thereby reducing the energy consumption of the heating device 12, and the catalytic layer 1111 can further increase the combustion (chemical reaction) rate of the mixture, further enhance the jet intensity ejected from the precombustion chamber 111, and improve the ignition effect of the ignition component 1.

[0052] At the same time, by catalyzing the combustion of fuel in the pre-combustion chamber 111 through the catalytic layer 1111, the formation of carbon deposits on the inner wall of the pre-combustion chamber 111 by incomplete combustion products can be reduced, the reliability and stability of the ignition component 1 can be improved, and the number of times the carbon deposits need to be cleaned can be reduced, thereby reducing operation and maintenance costs and downtime. In addition, even if more than a specified amount of carbon deposits are formed in the pre-combustion chamber, the carbon deposits in the shell 11 can still be eliminated by the heating device 12. The catalytic layer 1111 can reduce the temperature required to ignite the carbon deposits, so that the thermal device can heat the fuel to 0.7 to 0.9 times the auto-ignition temperature of the carbon deposits to achieve combustion of the carbon deposits, reduce energy consumption and costs, and eliminate the adverse effects of carbon deposits on the operation of the pre-combustion chamber 111 without the need to disassemble and replace the pre-combustion chamber 111.

[0053] In addition, since the heating device 12 can heat the fuel to 0.7 times to 0.9 times the auto-ignition temperature of the fuel to achieve combustion of the fuel, the degree of combustion of the fuel in the pre-combustion chamber 111 can be controlled by the heating device 12 to generate free radicals of a specific concentration and eject them from the pre-combustion chamber 111 to the outside of the shell 11 with the air flow, so that the free radicals of the specific concentration can effectively shorten the time to ignite the fuel in the environment where the shell 11 is located, thereby accelerating the combustion rate.

[0054] When the ignition component 1 of the present application is applied to the engine 100, taking the gasoline engine 100 as an example, the fuel in the pre-combustion chamber 111 is gasoline. Of course, the ignition component 1 of the present application can also be an engine 100 of other fuels, such as natural gas, methanol, ethanol, diesel, etc.

[0055] Specifically, the engine 100 includes a housing 2 and an ignition component 1. The housing 2 has a combustion chamber 21. The housing 11 is located in the combustion chamber 21, and the pre-combustion chamber 111 is connected to the combustion chamber 21. Thus, the fuel in the pre-combustion chamber 111 is heated by the heating device 12, and the catalytic layer 1111 catalyzes the combustion of the fuel in the pre-combustion chamber 111, so that the high-temperature and high-pressure gas generated by the fuel in the pre-combustion chamber 111 can be ejected from the pre-combustion chamber 111 into the combustion chamber 21 to ignite the fuel in the combustion chamber. It should be noted that before the fuel is ignited, the pre-combustion chamber 111 and the combustion chamber 21 both contain a mixture with fuel. The fuel in the pre-combustion chamber 111 is ejected into the combustion chamber 21 and ignites the fuel in the combustion chamber to push the piston of the engine 100 to perform work.

[0056] It should be noted that the auto-ignition temperature of the fuel referred to in the embodiment of the present application refers to the auto-ignition temperature of the fuel in the current state in the pre-combustion chamber 111, which is related to factors such as pressure, temperature, air volume, fuel volume, etc. in the pre-combustion chamber 111. It can be calculated in real time after collecting relevant data, or it can be obtained by calibrating the auto-ignition temperature under various working conditions through a table and querying the contents of the table.

[0057] According to the ignition component 1 of the embodiment of the present invention, the shell 11 has a pre-combustion chamber 111, and the fuel in the pre-combustion chamber 111 is heated by the heating device 12. The inner wall of the pre-combustion chamber 111 has a catalytic layer 1111. The catalytic layer 1111 catalyzes the combustion of the fuel in the pre-combustion chamber 111, so that the heating device 12 can heat the fuel to 0.7 times to 0.9 times the auto-ignition temperature of the fuel to achieve combustion of the fuel. The catalytic layer 1111 reduces the temperature required to ignite the fuel, shortens the flame propagation process, increases the combustion rate, strengthens the jet intensity of the airflow ejected from the pre-combustion chamber 111, and improves the ignition effect of the ignition component 1. At the same time, the degree of combustion of the fuel in the pre-combustion chamber 111 by the heating device 12 can be controlled to generate a specific concentration of free radicals and eject them from the pre-combustion chamber 111 with the airflow, effectively shortening the time it takes to ignite the fuel in the environment where the shell 11 is located, and further accelerating the combustion rate.

[0058] In some embodiments of the present invention, the thickness of the catalytic layer 1111 is 5 μm-20 μm. It is understandable that the thicker the catalytic layer 1111, the better the catalytic effect. However, the thicker the catalytic layer 1111, the easier it is for the catalytic layer 1111 to fall off the inner wall of the pre-combustion chamber 111, and the higher the cost. Therefore, by limiting the thickness of the catalytic layer 1111 to 5 μm-20 μm, while ensuring the catalytic effect of the catalytic layer 1111 on the fuel in the pre-combustion chamber 111, the bonding strength of the catalytic layer 1111 to the inner wall of the pre-combustion chamber 111 is ensured, thereby improving the reliability and stability of the ignition component 1.

[0059] It should be noted that the thickness of the catalytic layer 1111 can be 5μm, 6μm, 7μm, 8μm, 9μm, 10μm, 11μm, 12μm, 13μm, 14μm, 15μm, 16μm, 17μm, 18μm, 19μm or 20μm.

[0060] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the catalytic layer 1111 covers the entire inner wall surface of the pre-combustion chamber 111. Therefore, such an arrangement can further enhance the catalytic effect of the catalytic layer 1111 on the fuel in the pre-combustion chamber 111, further enhance the combustion rate and the jet intensity of the airflow ejected from the pre-combustion chamber 111, and thus further enhance the ignition effect of the ignition component 1.

[0061] In some embodiments of the present invention, the catalytic layer 1111 includes at least one of a noble metal element and a transition metal element. It is understandable that the unfilled d orbital of the noble metal element (such as platinum Pt, palladium Pd) gives it a strong redox ability, and the noble metal can effectively dissociate O2 into active oxygen atoms, thereby achieving the catalytic effect of the catalytic layer 1111 on the fuel in the pre-combustion chamber 111. The catalytic activity of the transition metal element (such as nickel Ni, iron Fe, cobalt Co) is derived from its unique d orbital electronic structure, which can independently catalyze the combustion reaction through oxygen activation, surface adsorption and anti-carbon deposition mechanisms, thereby achieving the catalytic effect of the catalytic layer 1111 on the fuel in the pre-combustion chamber 111. At the same time, the composite catalytic layer 1111 composed of the noble metal element and the transition metal element can combine the advantages of the two elements, while achieving the catalytic effect of the catalytic layer 1111 on the fuel in the pre-combustion chamber 111 while improving stability and activity. Therefore, at least one of the noble metal element and the transition metal element can be used as the catalytic layer 1111 according to the different needs of the user, thereby improving versatility.

[0062] In some embodiments of the present invention, the heating device 12 includes an electric heating wire (not shown in the figure). The electric heating wire is embedded in the shell 11. Thus, the heat energy of the electric heating wire is transferred to the shell 11 by the electric heating wire, and the heat energy is transferred to the pre-combustion chamber 111 through the shell 11 so that the pre-combustion chamber 111 can be heated to a first set temperature (the first set temperature is 0.7 times to 0.9 times the auto-ignition temperature of the fuel), thereby realizing the combustion of the fuel in the pre-combustion chamber 111. At the same time, the electric heating wire has a simple structure, does not require a complex mechanical structure, can be bent into any shape (such as spiral, wavy), is flexible to install, and is adaptable to shells 11 of different shapes, effectively reducing the cost of the ignition component 1.

[0063] Furthermore, if Figure 1 and Figure 2 As shown, the heating device 12 also includes a power supply 121, which is used to energize the electric heating wire so that current passes through the resistance wire to generate heat, so that the heat energy generated by the electric heating wire can be conducted to the pre-combustion chamber 111 through the shell 11, thereby realizing fuel combustion in the pre-combustion chamber 111.

[0064] Furthermore, if Figure 1 and Figure 2 As shown, the heating device 12 also includes a control device 122, which has functions such as temperature setting, sensor data processing, power regulation, safety protection logic, fault diagnosis and user interaction, thereby improving the reliability of the ignition component 1, and can adjust the electric energy flowing to the electric heating wire as needed, thereby adjusting the temperature in the pre-combustion chamber 111.

[0065] In some embodiments of the present invention, there are multiple electric heating wires, and the multiple electric heating wires are evenly laid in the housing 11. Therefore, when the electric heating wires heat the pre-combustion chamber 111, such an arrangement can achieve uniform heating of the entire pre-combustion chamber 111, avoiding the occurrence of local hot spots, thereby achieving uniform heating of the fuel in the pre-combustion chamber 111, so that the combustion in the pre-combustion chamber 111 is simultaneous, forming a stronger jet compared to flame propagation ignition, and improving the combustion rate.

[0066] In a specific embodiment, the plurality of electric heating wires include a first group of electric heating wires and a second group of electric heating wires, the first group of electric heating wires extending in a first direction and being a plurality of electric heating wires spaced apart along a second direction, the second group of electric heating wires extending in a second direction and being a plurality of electric heating wires spaced apart along a first direction, the first group of electric heating wires and the second group of electric heating wires being arranged crosswise in the first direction and the second direction, so that the plurality of electric heating wires are arranged in a "field shape" in the housing 11, thereby achieving uniform heating throughout the pre-combustion chamber 111. It should be noted that the manner in which the plurality of electric heating wires of the present application are laid in the housing 11 is not limited thereto, and those skilled in the art can make a choice according to actual needs in achieving uniform laying of the plurality of electric heating wires in the housing 11.

[0067] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the outer surface of the shell 11 has an insulating layer 112. Thus, the insulating layer 112 provides insulation for the shell 11, effectively preventing the heat in the pre-combustion chamber 111 from being dissipated outward, thereby concentrating the heat in the pre-combustion chamber 111, ensuring the heating efficiency of the heating device 12 on the fuel in the pre-combustion chamber 111, ensuring combustion efficiency, and improving reliability.

[0068] Furthermore, the insulating material layer is porous anodized aluminum. Porous anodized aluminum is an aluminum oxide material obtained by anodizing aluminum metal under acidic conditions. This material has a good thermal insulation effect; or, the material of the thermal insulation layer 112 is silica-reinforced porous anodized aluminum. A silica coating with a micron-level thickness is formed on the surface of the porous anodized aluminum. The silica coating can effectively improve the wear resistance of the porous anodized aluminum. This material has excellent thermal insulation properties and can effectively prevent the heat of the pre-combustion chamber 111 from dissipating outward. Of course, the material of the thermal insulation layer 112 is not limited to the above embodiment, and those skilled in the art can make a selection according to actual needs.

[0069] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the housing 11 has an injection hole 113, which connects the pre-combustion chamber 111 and the environment outside the housing 11. Therefore, the high-temperature and high-pressure gas generated by the combustion of fuel in the pre-combustion chamber 111 can be injected from the injection hole 113 to the environment outside the housing 11 to ignite the fuel in the environment where the housing 11 is located.

[0070] When the ignition component 1 of the present application is applied to an engine 100, the engine 100 includes a housing 2 and the ignition component 1. The housing 2 has a combustion chamber 21. The housing 11 is located within the combustion chamber 21, and the pre-combustion chamber 111 is connected to the combustion chamber 21. Thus, the fuel in the pre-combustion chamber 111 is heated by the heating device 12, and the catalytic layer 1111 catalyzes the combustion of the fuel in the pre-combustion chamber 111, so that high-temperature and high-pressure gas generated by the fuel in the pre-combustion chamber 111 is ejected from the injection hole 113 into the combustion chamber 21, thereby igniting the fuel in the combustion chamber.

[0071] It should be noted that the injection hole 113 penetrates the catalytic layer 1111 so that the fuel in the pre-combustion chamber 111 can be smoothly ejected from the injection hole 113. At the same time, the catalytic layer 1111 can be provided on the inner wall of the injection hole 113 to further enhance the catalytic effect of the catalytic layer 1111 on the fuel.

[0072] Furthermore, there are multiple injection holes 113, and the multiple injection holes 113 are evenly distributed on the shell 11. Therefore, the high-temperature and high-pressure gas generated by the combustion of fuel in the pre-combustion chamber 111 can be injected from the multiple injection holes 113 to the external environment of the shell 11 to ignite the fuel in the environment where the shell 11 is located, and the multiple evenly distributed injection holes 113 can make the burned fuel spray in multiple directions, so that the fuel in various parts of the combustion chamber 21 can be quickly ignited.

[0073] Figure 2 Three injection holes 113 are shown for illustrative purposes, but after reading the following technical solution, ordinary technicians can obviously understand that the solution can be applied to the technical solution of two or more injection holes 113, which also falls within the scope of protection of the present invention.

[0074] In some embodiments, as Figure 1 and Figure 2 As shown, the side of the housing 11 opposite the top of the cylinder is spherical, and the interior of the pre-combustion chamber 111 is also spherical. Of course, in other examples, the portion of the housing 11 is not limited to a spherical surface and can also be a non-spherical surface or other structure. Furthermore, those skilled in the art can adjust the volume and surface area of ​​the ignition chamber according to actual needs.

[0075] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the ignition component 1 further includes a nozzle 13. The nozzle 13 is at least partially located in the pre-combustion chamber 111 and is used to inject fuel into the pre-combustion chamber 111. Thus, through such an arrangement, the heating device 12 can heat the fuel injected into the pre-combustion chamber 111 by the nozzle 13, thereby achieving combustion of the fuel.

[0076] The following describes an ignition control method of the ignition component 1 according to an embodiment of the present invention.

[0077] According to the ignition control method of the ignition component 1 of the embodiment of the present invention, Figure 1 and Figure 2 As shown, the ignition component 1 mentioned above, as Figure 3 As shown, the ignition control method includes: obtaining the auto-ignition temperature of the fuel in the pre-combustion chamber 111. It is understandable that the auto-ignition temperature of the fuel needs to be obtained first according to the type of fuel in the pre-combustion chamber 111 (such as gasoline, diesel, natural gas, hydrogen, etc.).

[0078] The heating device 12 is controlled to heat the fuel in the pre-combustion chamber 111 to a first set temperature, the auto-ignition temperature of the fuel is a, the first set temperature is b, and the following conditions are satisfied: 0.7a≤b≤0.9a. It is understandable that, since the inner wall of the pre-combustion chamber 111 has a catalytic layer 1111, during the process of the heating device 12 heating the fuel in the pre-combustion chamber 111, the catalytic layer 1111 catalyzes the combustion of the fuel in the pre-combustion chamber 111, so that the heating device 12 heats the fuel in the pre-combustion chamber 111 to the first set temperature to achieve combustion of the fuel. Thus, after obtaining the first set temperature by obtaining the auto-ignition temperature of the fuel in the pre-combustion chamber 111 according to the previous step, the heating device 12 is controlled to heat the fuel in the pre-combustion chamber 111 to the first set temperature, so that the high-temperature and high-pressure gas generated by the combustion of the fuel in the pre-combustion chamber 111 can be ejected from the pre-combustion chamber 111 to the external environment of the shell 11, so as to ignite the fuel in the environment where the shell 11 is located.

[0079] It should be noted that the first set temperature may be 0.7 times, 0.75 times, 0.8 times, 0.85 times or 0.9 times the auto-ignition temperature of the fuel.

[0080] According to the ignition control method of the ignition component 1 of an embodiment of the present invention, the ignition control method includes obtaining the auto-ignition temperature of the fuel in the pre-combustion chamber 111; controlling the heating device 12 to heat the fuel in the pre-combustion chamber 111 to a first set temperature, the auto-ignition temperature of the fuel is a, the first set temperature is b, and satisfies: 0.7a≤b≤0.9a, so that the fuel in the pre-combustion chamber 111 burns and the high-temperature and high-pressure gas generated can be ejected from the pre-combustion chamber 111 to the external environment of the shell 11 to ignite the fuel in the environment where the shell 11 is located.

[0081] In some embodiments of the present invention, Figure 4 As shown, the ignition control method includes: obtaining the temperature within the pre-combustion chamber 111. It is understood that the temperature within the pre-combustion chamber 111 affects the combustion temperature rate of the fuel within the pre-combustion chamber 111 and the pressure within the pre-combustion chamber 111, thereby affecting the flow rate of the airflow ejected from the pre-combustion chamber 111, and the temperature within the pre-combustion chamber 111 affects the generation of free radicals in the fuel within the pre-combustion chamber 111. Therefore, after controlling the heating device 12 to heat the fuel within the pre-combustion chamber 111 to a first set temperature, the temperature within the pre-combustion chamber 111 is obtained to ensure the flow rate of the airflow ejected from the pre-combustion chamber 111 and the free radical content in the airflow.

[0082] Optionally, the temperature in the pre-combustion chamber 111 may be acquired in real time by a temperature sensor disposed in the pre-combustion chamber 111 .

[0083] The heating power of the heating device 12 is controlled according to the temperature in the pre-combustion chamber 111. Thus, the heating power of the heating device 12 can be controlled according to the temperature in the pre-combustion chamber 111 obtained in the above steps, thereby controlling the combustion of the fuel in the pre-combustion chamber 111, and further controlling the flow rate of the airflow ejected from the pre-combustion chamber 111 and the free radical content in the airflow, so as to ensure the ignition effect of the ignition component 1.

[0084] In some embodiments of the present invention, controlling the heating power of the heating device 12 based on the temperature in the pre-combustion chamber 111 includes: determining that the temperature in the pre-combustion chamber 111 is less than a first preset temperature, and increasing the heating power of the heating device 12. It is understandable that a temperature in the pre-combustion chamber 111 that is too low will result in lower fuel combustion efficiency and lower pressure in the pre-combustion chamber 111, resulting in a slower flow rate of the airflow ejected from the pre-combustion chamber 111, affecting the ignition effect of the ignition component 1. Therefore, the first preset temperature is set as the lower limit of the temperature in the pre-combustion chamber 111. If it is determined that the temperature in the pre-combustion chamber 111 is less than the first preset temperature, the heating power of the heating device 12 is increased, thereby increasing the temperature in the pre-combustion chamber 111.

[0085] If the temperature in the pre-combustion chamber 111 is determined to be greater than the second preset temperature, the heating power of the heating device 12 is reduced. The first preset temperature is less than the second preset temperature. It is understood that an excessively high temperature in the pre-combustion chamber 111 can reduce the free radical content of the fuel, thereby reducing the free radical content of the airflow ejected from the pre-combustion chamber 111 and affecting the ignition effect of the ignition component 1. Therefore, the second preset temperature is set as the upper limit of the temperature in the pre-combustion chamber 111. If the temperature in the pre-combustion chamber 111 is determined to be greater than the second preset temperature, the heating power of the heating device 12 is reduced, thereby reducing the temperature in the pre-combustion chamber 111.

[0086] Therefore, according to the above control method, the heating power of the heating device 12 is controlled according to the temperature in the pre-combustion chamber 111, thereby ensuring the flow rate of the airflow ejected from the pre-combustion chamber 111 and the free radical content in the airflow, thereby ensuring the ignition effect of the ignition component 1.

[0087] In some embodiments, the first preset temperature is 0.7 times the auto-ignition temperature of the fuel, and the second preset temperature is 0.9 times the auto-ignition temperature of the fuel.

[0088] In some embodiments of the present invention, Figure 5As shown, the ignition control method includes determining the free radical content within the pre-combustion chamber 111. It is understood that the free radical content generated by the combustion of the fuel within the pre-combustion chamber 111 affects the free radical content in the airflow ejected from the pre-combustion chamber 111. If the free radical content in the airflow ejected from the pre-combustion chamber 111 is low, it takes longer for the fuel in the environment surrounding the housing 11 to ignite. Therefore, after controlling the heating device 12 to heat the fuel within the pre-combustion chamber 111 to a first set temperature, the free radical content within the pre-combustion chamber 111 is determined to ensure a consistent free radical content in the airflow ejected from the pre-combustion chamber 111.

[0089] Optionally, the free radical content in the pre-combustion chamber 111 can be obtained by exciting the free radicals with a laser of a specific wavelength and detecting the fluorescence intensity emitted when the free radicals are de-excited; or, the free radical content in the pre-combustion chamber 111 can be obtained by covering the free radical absorption spectrum with the light wavelength and inverting the concentration by the absorbance.

[0090] The heating power of the heating device 12 is controlled according to the free radical content in the pre-combustion chamber 111. Thus, the heating power of the heating device 12 can be controlled according to the free radical content in the pre-combustion chamber 111 obtained in the above steps, thereby controlling the combustion of the fuel in the pre-combustion chamber 111, and further controlling the free radical content in the airflow ejected from the pre-combustion chamber 111, so as to ensure the ignition effect of the ignition component 1.

[0091] In some embodiments of the present invention, controlling the heating power of the heating device 12 according to the free radical content in the pre-combustion chamber 111 includes: determining that the free radical content in the pre-combustion chamber 111 is less than a first preset content, and reducing the heating power of the heating device 12.

[0092] It is understandable that the temperature within the precombustion chamber 111 is inversely proportional to the free radical content generated by the fuel within the precombustion chamber 111. Excessively high temperatures within the precombustion chamber 111 can reduce the free radical content of the fuel, thereby reducing the free radical content of the airflow ejected from the precombustion chamber 111 and affecting the ignition effect of the ignition component 1. Therefore, the first preset content is set as the lower limit of the free radical content within the precombustion chamber 111. When the free radical content within the precombustion chamber 111 is determined to be less than the first preset content, the heating power of the heating device 12 is reduced, thereby reducing the temperature within the precombustion chamber 111 and increasing the free radical content within the precombustion chamber 111 and the free radical content in the airflow ejected from the precombustion chamber 111, thereby ensuring the ignition effect of the ignition component 1.

[0093] It is determined that the free radical content in the pre-combustion chamber 111 is greater than the second preset content, and the heating power of the heating device 12 is increased. The first preset content is less than the second preset content. It can be understood that the temperature in the pre-combustion chamber 111 is inversely proportional to the free radical content generated by the fuel in the pre-combustion chamber 111. An excessively high free radical content in the pre-combustion chamber 111 indicates that the combustion temperature of the fuel is too low. An excessively low temperature in the pre-combustion chamber 111 will result in lower fuel combustion efficiency and pressure in the pre-combustion chamber 111, resulting in a slower flow rate of the airflow ejected from the pre-combustion chamber 111, affecting the ignition effect of the ignition component 1. Therefore, the second preset content is set as the upper limit of the free radical content in the pre-combustion chamber 111, and it is determined that the free radical content in the pre-combustion chamber 111 is greater than the second preset content. The heating power of the heating device 12 is increased, thereby increasing the temperature in the pre-combustion chamber 111.

[0094] Therefore, according to the above control method, the heating power of the heating device 12 is controlled according to the free radical content in the pre-combustion chamber 111, thereby ensuring the flow rate of the airflow ejected from the pre-combustion chamber 111 and the free radical content in the airflow, and ensuring the ignition effect of the ignition component 1.

[0095] The following describes a method for controlling the cleaning of the ignition component 1 according to an embodiment of the present invention.

[0096] According to the cleaning control method of the ignition component 1 of the embodiment of the present invention, Figure 1 and Figure 2 As shown, the ignition component 1 mentioned above, as Figure 6 As shown, the cleaning control method includes: determining whether the amount of carbon deposits in the pre-combustion chamber 111 exceeds a set value. It is understandable that the products of incomplete combustion of the fuel will form carbon deposits on the inner wall of the pre-combustion chamber 111. The carbon deposits covering the catalytic layer 1111 will cause the catalytic effect to deteriorate. At the same time, the carbon deposits will cause the heat transfer in the pre-combustion chamber 111 to deteriorate, affecting the heating effect of the heating device 12 on the fuel. The carbon deposits in the pre-combustion chamber 111 need to be cleaned regularly to ensure the reliability and stability of the ignition component 1. Therefore, it is first determined that the amount of carbon deposits in the pre-combustion chamber 111 exceeds the set value, and then the subsequent carbon deposit cleaning control method is executed.

[0097] Obtain the auto-ignition temperature of the carbon deposits in the pre-combustion chamber 111. After determining that the amount of carbon deposits in the pre-combustion chamber 111 exceeds a set value, it is necessary to obtain the auto-ignition temperature of the carbon deposits in the pre-combustion chamber 111 based on the type of fuel in the pre-combustion chamber 111 (such as gasoline, diesel, natural gas, hydrogen, etc.).

[0098] The heating device 12 is controlled to heat the carbon deposits in the pre-combustion chamber 111 to a second set temperature, the auto-ignition temperature of the carbon deposits c, the second set temperature is d, and satisfies: 0.7c≤d≤0.9c. It can be understood that since the inner wall of the pre-combustion chamber 111 has a catalytic layer 1111, during the process of the heating device 12 heating the carbon deposits in the pre-combustion chamber 111, the catalytic layer 1111 catalyzes the combustion of the carbon deposits in the pre-combustion chamber 111, so that the heating device 12 heats the fuel in the pre-combustion chamber 111 to the second set temperature to achieve the combustion of the carbon deposits, thereby eliminating the carbon deposits in the pre-combustion chamber 111. Therefore, after obtaining the second set temperature by obtaining the auto-ignition temperature of the carbon deposits in the pre-combustion chamber 111 according to the previous step, the heating device 12 is controlled to heat the carbon deposits in the pre-combustion chamber 111 to the second set temperature, so that the carbon deposits in the pre-combustion chamber 111 are burned, thereby eliminating the carbon deposits in the pre-combustion chamber 111 and ensuring the reliability and stability of the ignition component 1. At the same time, the catalyst layer can reduce energy consumption and cost.

[0099] It should be noted that the second set temperature may be 0.7 times, 0.75 times, 0.8 times, 0.85 times or 0.9 times the carbon deposit auto-ignition temperature.

[0100] It should be noted that when executing the cleaning control method of the ignition component 1, the ECU controls the nozzle 13 to stop spraying oil into the pre-combustion chamber 111, so that the carbon deposits are burned under the action of the heating device 12 and the catalytic layer 1111 to form gaseous carbon dioxide.

[0101] According to the cleaning control method of the ignition component 1 of an embodiment of the present invention, by determining that the amount of carbon deposits in the pre-combustion chamber 111 exceeds a set value; obtaining the auto-ignition temperature of the carbon deposits in the pre-combustion chamber 111; controlling the heating device 12 to heat the carbon deposits in the pre-combustion chamber 111 to a second set temperature, the auto-ignition temperature of the carbon deposits c, the second set temperature is d, and satisfies: 0.7c≤d≤0.9c, so that the carbon deposits in the pre-combustion chamber 111 are burned, thereby eliminating the carbon deposits in the pre-combustion chamber 111, ensuring the reliability and stability of the ignition component 1, and the catalyst layer can reduce energy consumption and cost, thereby achieving the elimination of the adverse effects of carbon deposits on the operation of the pre-combustion chamber 111 without the need to disassemble and replace the pre-combustion chamber 111.

[0102] Next, the engine 100 according to the embodiment of the present invention will be described.

[0103] According to an embodiment of the present invention, the engine 100 includes a housing 2 and an ignition component 1. The housing 2 has a combustion chamber 21. The housing 11 is located in the combustion chamber 21. The pre-combustion chamber 111 is connected to the combustion chamber 21. Thus, the fuel in the pre-combustion chamber 111 is heated by the heating device 12, and the catalytic layer 1111 catalyzes the combustion of the fuel in the pre-combustion chamber 111, so that the high-temperature and high-pressure gas generated by the fuel in the pre-combustion chamber 111 can be ejected from the pre-combustion chamber 111 into the combustion chamber 21 to ignite the fuel in the combustion chamber. It should be noted that before the fuel is ignited, the pre-combustion chamber 111 and the combustion chamber 21 both contain a mixture with fuel. The fuel in the pre-combustion chamber 111 is ejected into the combustion chamber 21 and ignites the fuel in the combustion chamber to push the piston of the engine 100 to perform work.

[0104] At the same time, the inner wall of the pre-combustion chamber 111 is provided with a catalytic layer 1111, and the catalytic layer 1111 catalyzes the combustion of the fuel in the pre-combustion chamber 111, so that the heating device 12 can heat the fuel to 0.7 times to 0.9 times the auto-ignition temperature of the fuel to achieve combustion of the fuel, thereby reducing the temperature required to ignite the fuel in the pre-combustion chamber 111 through the catalytic layer 1111, shortening the flame propagation process, increasing the combustion rate, and strengthening the jet intensity of the airflow ejected from the pre-combustion chamber 111 to the combustion value, thereby improving the combustion efficiency of the engine 100 and thus improving the ignition efficiency of the engine 100.

[0105] In addition, the degree of combustion of the fuel in the pre-combustion chamber 111 by the heating device 12 can be controlled to generate free radicals of a specific concentration and eject them from the pre-combustion chamber 111 with the air flow, thereby effectively shortening the time to ignite the fuel in the combustion chamber 21 and further accelerating the combustion rate.

[0106] According to an embodiment of the present invention, the engine 100 is provided with an ignition component 1, a housing 2 having a combustion chamber 21, a housing 11 located within the combustion chamber 21, a pre-combustion chamber 111 communicating with the combustion chamber 21, and a catalytic layer 1111 disposed on the inner wall of the pre-combustion chamber 111. The catalytic layer 1111 catalyzes the combustion of the fuel in the pre-combustion chamber 111, so that the heating device 12 can heat the fuel to 0.7 to 0.9 times the auto-ignition temperature of the fuel to achieve combustion of the fuel. The catalytic layer 1111 thereby reduces the temperature required to ignite the fuel in the pre-combustion chamber 111, shortens the flame propagation process, increases the combustion rate, strengthens the jet intensity of the airflow ejected from the pre-combustion chamber 111 to the combustion point, and thereby improves the combustion efficiency of the engine 100, thereby improving the ignition efficiency of the engine 100. Furthermore, the degree of combustion of the fuel in the pre-combustion chamber 111 by the heating device 12 can be controlled to generate a specific concentration of free radicals that are ejected from the pre-combustion chamber 111 along with the airflow, effectively shortening the time it takes to ignite the fuel in the combustion chamber 21 and further accelerating the combustion rate.

[0107] Next, a vehicle according to an embodiment of the present invention will be described.

[0108] A vehicle according to an embodiment of the present invention includes an engine 100 .

[0109] According to an embodiment of the present invention, a vehicle is provided with an engine 100, wherein the inner wall of a pre-combustion chamber 111 is provided with a catalytic layer 1111. The catalytic layer 1111 catalyzes the combustion of the fuel in the pre-combustion chamber 111, so that the heating device 12 can heat the fuel to 0.7 to 0.9 times the auto-ignition temperature of the fuel to achieve combustion of the fuel. Thus, the catalytic layer 1111 reduces the temperature required to ignite the fuel in the pre-combustion chamber 111, shortens the flame propagation process, increases the combustion rate, strengthens the jet intensity of the airflow ejected from the pre-combustion chamber 111 to the combustion point, improves the combustion efficiency of the engine 100, and thus improves the ignition efficiency of the engine 100. In addition, by controlling the degree of combustion of the fuel in the pre-combustion chamber 111 by the heating device 12, a specific concentration of free radicals can be generated and ejected from the pre-combustion chamber 111 along with the airflow, effectively shortening the time it takes to ignite the fuel in the combustion chamber 21 and further accelerating the combustion rate.
