DETAILED DESCRIPTION

[0030] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0031] The following describes an engine exhaust gas recirculation ultra-high temperature heating system and a vehicle according to an embodiment of the present application with reference to the accompanying drawings. First, the engine exhaust gas recirculation ultra-high temperature heating system according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0032] Figure 1 It is a block diagram of an engine exhaust gas recirculation ultra-high temperature heating system according to an embodiment of the present application.

[0033] For example, Figure 1 As shown, the engine exhaust gas recirculation ultra-high temperature heating system 10 includes: an energy conversion component 100 , a catalytic component 200 and a heating component 300 .

[0034] Among them, the energy conversion component 100 is used to convert the energy generated by the fuel combustion process into mechanical energy and generate exhaust gas; the input end of the catalytic component 200 is connected to the first output end of the energy conversion component 100, and is used to catalytically decompose the exhaust gas to obtain water vapor and gas to be discharged, so as to discharge the gas to be discharged through the first output end of the catalytic component 200; the heating component 300 includes a heating unit 301, the input end of the heating component 300 is connected to the second output end of the catalytic component 200, and the heating unit 301 is connected to the second output end of the energy conversion component 100. The heating unit 301 heats the water vapor based on the heat generated by the second output end of the energy conversion component 100 to generate hydrogen and oxygen.

[0035] In the field of modern industry and energy utilization, energy conversion and efficient utilization have always been key issues in promoting scientific and technological progress and environmental protection. The engine exhaust gas recirculation ultra-high temperature heating system 10 proposed in the embodiment of the present application cleverly integrates the energy conversion component 100, the catalytic component 200 and the heating component 300, realizing a closed-loop process from fuel combustion to clean energy generation.

[0036] Specifically, the energy conversion component 100, as the cornerstone of the entire system, has the core function of efficiently converting the chemical energy of the fuel into mechanical energy, while using the exhaust gas generated during the fuel combustion process as a byproduct. The relevant technology can ensure that the fuel burns under optimal conditions, maximizes energy output, and minimizes the generation of harmful substances by optimizing the combustion chamber design, introducing advanced ignition systems and precise fuel injection control technology. As a key link in the energy conversion chain, the catalytic component 200 can receive the exhaust gas generated by the energy conversion component 100 and use advanced catalyst technology to catalytically decompose the harmful gases in the exhaust gas. In this process, complex chemical reactions cause harmful substances in the exhaust gas, such as nitrogen oxides, sulfides, etc., to be converted into green and harmless water vapor and gases to be discharged (such as carbon dioxide, etc.). The catalytic component 200 uses existing catalytic materials, such as precious metal catalysts, rare earth-based catalysts, etc., which can not only improve the catalytic efficiency, but also broaden the range of types of exhaust gases that can be treated. The heating component 300 utilizes the waste heat generated by the combustion of the fuel in the energy conversion component 100 and the water vapor obtained after the treatment of the catalytic component 200. Through the precise control of the heating unit 301, the water vapor is efficiently heated. This process can not only recycle the waste heat, but also decompose the water vapor into hydrogen and oxygen. The introduction of the heating component 300 not only improves the energy utilization efficiency of the entire system, but also makes it possible to achieve a diversified and clean energy structure.

[0037] In summary, the engine exhaust gas recirculation ultra-high temperature heating system 10 realizes a complete closed loop from fuel combustion to clean energy generation through the close cooperation of three components, which not only improves the fuel utilization efficiency and reduces the emission of harmful gases, but also reduces the overall energy consumption and cost through energy recycling.

[0038] Optionally, in some embodiments, the catalytic component 300 is a three-way catalyst.

[0039] It is understandable that the three-way catalytic converter, as the core of the exhaust gas purification system, is filled with a honeycomb carrier made of special ceramic materials, and the surface of the carrier is coated with precious metal catalysts such as platinum, rhodium, and palladium. When the exhaust gas after fuel combustion passes through these precious metal catalysts, a series of complex chemical reactions, such as redox reactions, will occur, thereby converting harmful substances such as carbon monoxide, hydrocarbons and nitrogen oxides in the exhaust gas into harmless carbon dioxide, nitrogen, water and oxygen. The wide application of three-way catalytic converters has played a vital role in improving air quality and protecting human health.

[0040] Optionally, in some embodiments, the energy conversion assembly 100 is an engine cylinder.

[0041] As the source of vehicle power, the performance of the engine cylinder directly affects the vehicle's acceleration, fuel economy and overall performance. In related technologies, the design of vehicle engine cylinders uses a variety of advanced technologies, such as direct injection and turbocharging, to improve combustion efficiency and power output.

[0042] Take direct injection technology as an example. This technology achieves more precise fuel control and a more efficient combustion process by injecting fuel directly into the cylinder to mix with air. It can not only improve the power and response speed of the engine, but also significantly reduce fuel consumption and exhaust emissions.

[0043] It can be seen that the catalytic component (i.e. the three-way catalytic converter) and the energy conversion component (i.e. the engine cylinder) each undertake the important tasks of purifying exhaust gas and converting energy, and together provide the vehicle with powerful power support and environmental protection performance guarantee.

[0044] Optionally, in some embodiments, Figure 2 As shown, the engine exhaust gas recirculation ultra-high temperature heating system 10 further includes: a power supply component 400 , which is connected to the heating unit 301 and is used to supply power to the heating unit 301 .

[0045] Optionally, in some embodiments, the heating unit 301 is a heating wire.

[0046] It is understandable that the core of the engine exhaust gas recirculation ultra-high temperature heating system 10 lies in its unique ultra-high temperature heating unit 301. This design solves the problems that may exist in the traditional EGR system, such as insufficient exhaust gas temperature and limited recirculation effect. The heating unit 301 is the "heart" of the entire system, and its performance is directly related to the overall operating efficiency and environmental protection effect of the system.

[0047] As one of the energy sources of the heating unit 301, the power supply component 400 can stably and efficiently provide the required electrical energy for the heating unit 301. The introduction of this component not only simplifies the system structure, but also significantly improves the response speed and stability of the system. In the specific implementation, the power supply component 400 realizes precise control of the heating unit 301 through precise circuit design. Whether it is started, run or stopped, the command response can be completed in the shortest time, thereby ensuring that the heating unit can always remain in the best working state. The heating unit 301 is a core component, and in some embodiments, it uses a heating wire as a heating element. This design not only has the advantages of small size, light weight, and fast heating speed, but also can effectively avoid the energy loss and safety hazards that may be caused by traditional heating methods. The heating wire is preferably made of high temperature resistant, corrosion resistant, and conductive materials to ensure that the heating unit 301 can maintain stable performance output under long-term, high-load operation.

[0048] By introducing ultra-high temperature heating technology, the engine exhaust gas recirculation ultra-high temperature heating system 10 significantly improves the effect of exhaust gas recirculation. Under the action of the heating unit 301, the harmful substances in the exhaust gas are further decomposed and converted, thereby effectively reducing the emission of pollutants such as nitrogen oxides. At the same time, due to the improvement of exhaust gas recirculation efficiency, the utilization rate of fuel is also improved. This means that the vehicle can consume less fuel during driving, thereby reducing operating costs.

[0049] Optionally, in some embodiments, Figure 2 As shown, the engine exhaust gas recirculation ultra-high temperature heating system 10 also includes: a switch component 500 arranged between the input end of the heating component 300 and the second output end of the catalytic component 200, and the switch component 500 is used to adjust the air intake amount of the pipeline to input water vapor into the heating component 300.

[0050] It is understandable that the switch assembly 500, as a bridge connecting the heating assembly 300 and the catalytic assembly 200, mainly functions to adjust the amount of water vapor entering the heating assembly 300. In specific implementation, the switch assembly 500 can be an exhaust gas recirculation valve. By precisely controlling the opening angle and response time of the valve, the system can dynamically adjust the intake amount of water vapor according to actual working conditions, such as engine load, speed, exhaust gas temperature, etc. In this way, the temperature in the heating assembly 300 can be kept stable and efficient, and energy waste or system overheating caused by excessive water vapor can be avoided.

[0051] In order to further understand the switch assembly 500, some specific examples can be cited. For example, in a certain brand of engine system, the switch assembly 500 uses an advanced electronic control unit (ECU) for precise control. The ECU quickly calculates the optimal water vapor intake volume by receiving real-time data from multiple sensors, such as engine speed, intake pressure, coolant temperature, etc., and controls the switch assembly 500 to make corresponding adjustments. This intelligent control method significantly improves the response speed of the entire exhaust gas recirculation ultra-high temperature heating system, while effectively reducing fuel consumption and emissions.

[0052] It can be seen that the design and application of the switch assembly 500 as an important component of the engine exhaust gas recirculation ultra-high temperature heating system 10 play an important role in improving system efficiency, reducing energy consumption and emissions. By accurately controlling the intake volume of water vapor, the temperature in the heating assembly 300 can be ensured to be stable and efficient, thereby promoting the full progress of the chemical reaction in the catalytic assembly 200.

[0053] Optionally, in some embodiments, Figure 2As shown, the engine exhaust gas recirculation ultra-high temperature heating system 10 also includes: a turbine 600, the input end of the turbine 600 is connected to the first output end of the energy conversion component 100, and the output end of the turbine 600 is connected to the input end of the catalytic component 200.

[0054] It is understandable that the turbine 600, as an important part of the internal combustion engine technology, has a working principle based on the ingenious application of fluid mechanics. In the embodiment of the present application, the turbine 600 is arranged between the energy conversion component 100 and the catalytic component 200, forming a key node that connects the upper and lower parts. Specifically, the input end of the turbine 600 is closely connected to the first output end of the energy conversion component 100, thereby ensuring that the high-temperature and high-pressure exhaust gas discharged from the energy conversion component 100 can flow smoothly into the turbine 600, thereby driving it to rotate at high speed. As the turbine 600 rotates rapidly, its internal complex blade structure begins to convert the kinetic energy of the exhaust gas into mechanical energy. This process not only effectively utilizes the exhaust gas energy that may have been wasted, but also provides power support for the subsequent catalytic process, and significantly improves the fuel economy of the engine. The output end of the turbine 600 is connected to the input end of the catalytic component 200, thereby ensuring that the exhaust gas fully compressed and heated by the turbine 600 can be directly sent to the catalytic component 200 for a more efficient chemical reaction. The interior of the catalytic component 200 is filled with specially prepared catalysts, which can accelerate the decomposition and conversion of harmful substances in the exhaust gas at high temperatures, thereby significantly reducing the pollution emissions of the vehicle's exhaust gas.

[0055] It is worth mentioning that the seamless connection between the turbine 600 and the catalytic assembly 200 can further optimize the thermal efficiency of the system. When the high-temperature exhaust gas flows through the turbine 600, its temperature is further increased. This preheating effect allows the catalytic reaction to start at a lower temperature, thereby reducing the preheating time and energy loss of the system.

[0056] It can be seen that the application of the turbine 600 in the engine exhaust gas recirculation ultra-high temperature heating system 10 not only realizes the efficient recovery and utilization of exhaust gas energy, but also promotes the clean treatment of exhaust emissions.

[0057] Optionally, in some embodiments, Figure 2 As shown, the engine exhaust gas recirculation ultra-high temperature heating system 10 also includes: a compressor 700, the input end of the compressor 700 is connected to the external atmospheric environment and the output end of the heating component 300 respectively, and the compressor 700 is used to absorb and compress the first mixed gas generated by the external air and the heating component 300 to obtain a compressed second mixed gas.

[0058] It is understandable that the input end of the compressor 700 is designed with two interfaces, one end is closely connected to the external atmospheric environment, and the other end is connected to the output end of the heating component 300, so as to ensure that the entire system can continuously inhale fresh air from the outside, and at the same time inhale the first mixed gas (i.e., hydrogen and oxygen) generated in the heating component 300. Under the powerful power of the compressor 700, the outside air and the first mixed gas are quickly inhaled and tightly compressed to form a compressed second mixed gas.

[0059] Optionally, in some embodiments, Figure 2 As shown, the engine exhaust gas recirculation ultra-high temperature heating system 10 also includes: an intercooler 800, the input end of the intercooler 800 is connected to the output end of the compressor 700, and the output end of the intercooler 800 is connected to the input end of the energy conversion component 100. The intercooler 800 is used to cool the compressed second mixed gas so that the cooled second mixed gas enters the energy conversion component 100 and burns together with the fuel.

[0060] Specifically, the intercooler 800, as an important part of the system, can quickly and effectively cool the high-temperature and high-pressure mixed gas output by the compressor 700. The intercooler 800 adopts advanced heat exchange technology, such as absorbing the heat in the high-temperature mixed gas through the circulation of coolant (such as water or ethylene glycol solution), thereby reducing the temperature of the mixed gas and increasing its density, thereby increasing the oxygen content when entering the combustion chamber, providing a strong guarantee for the full combustion of the fuel.

[0061] The second mixed gas cooled by the intercooler 800 is then sent to the energy conversion component 100 to be mixed with the fuel for combustion, thereby effectively reducing the emission of unburned hydrocarbons and nitrogen oxides, which is of great significance for improving air quality and reducing environmental pollution.

[0062] In order to facilitate those skilled in the art to further understand the engine exhaust gas recirculation ultra-high temperature heating system proposed in the embodiment of the present application, it is further elaborated below in conjunction with a specific implementation method.

[0063] For example, the exhaust gas generated after combustion in the engine cylinder flows through the turbine and is divided into two paths under the action of the three-way catalytic converter. One path is directly discharged to the outside atmosphere, while the other path re-enters the heating device through the fine adjustment of the exhaust gas recirculation valve. The heating device contains a heating wire. In the heating device, the heat source of the heating wire is divided into two parts, one of which comes from the vehicle battery, and the battery power is transmitted to the heating wire through the power line and converted into heat energy; the other part comes from the heat generated by the engine cylinder, and the heat is introduced into the heating wire through the high-temperature heat pipe. The water vapor in the exhaust gas discharged from the engine cylinder encounters the high temperature of the heating wire in the heating device and decomposes into hydrogen and oxygen. These gases can be sucked into the intercooler by the compressor together with the air from the outside atmosphere. Since the water vapor is decomposed during the heating process, no cooling water will enter the engine cylinder, thereby avoiding adverse effects on the fuel combustion process. The mixed gas cooled by the intercooler (i.e. hydrogen and oxygen obtained by decomposing water vapor, and air from the external atmospheric environment) then enters the engine cylinder and burns together with the fuel. This not only increases the engine's torque, but also shortens the combustion period, thereby improving thermal efficiency.

[0064] According to the engine exhaust gas recirculation ultra-high temperature heating system proposed in the embodiment of the present application, the energy generated by the fuel combustion process is converted into mechanical energy through the energy conversion component to generate exhaust gas; the exhaust gas is catalytically decomposed by the catalytic component to obtain water vapor and gas to be discharged; the water vapor is heated by the heating component based on the heat generated by the second output end of the energy conversion component to generate hydrogen and oxygen. Therefore, the engine exhaust gas recirculation ultra-high temperature heating system can heat the exhaust gas, decompose the water vapor in the exhaust gas into hydrogen and oxygen, and no cooling water is precipitated after cooling, which solves the problem of cooling water entering the engine cylinder and affecting fuel combustion, thereby improving thermal efficiency.

[0065] The present application also provides a vehicle, which includes Figure 1 An engine exhaust gas recirculation ultra-high temperature heating system of an embodiment.

[0066] According to the vehicle proposed in the embodiment of the present application, the exhaust gas can be heated by the engine exhaust gas recirculation ultra-high temperature heating system, so that the water vapor in the exhaust gas is decomposed into hydrogen and oxygen, and no cooling water is precipitated after cooling, which solves the problem of cooling water entering the engine cylinder and affecting fuel combustion, thereby improving thermal efficiency.
