[0002] EGR (Exhaust Gas Re-circulation) is a technology widely used in internal combustion engines to reduce the emission of nitrogen oxides. By returning part of the exhaust gas discharged by the engine to the intake manifold and re-entering the cylinder together with the fresh mixture, the combustion temperature in the cylinder can be reduced, thereby reducing the generation of NOx. Since the exhaust gas contains a large amount of polyatomic gases such as carbon dioxide, these gases cannot burn but have a high specific heat capacity and can absorb a large amount of heat, which reduces the maximum combustion temperature of the mixture in the cylinder.

[0023] 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.

[0024] The following describes the engine exhaust treatment structure, system, method, vehicle and storage medium of the embodiment of the present application with reference to the accompanying drawings. In response to the problems mentioned in the above background technology, the present application provides an engine exhaust treatment structure, which adds an ionization component to ionize the exhaust gas, decompose the water vapor in the exhaust gas, prevent the generation of condensed water, and improve the combustion efficiency of the engine. The power component receives the treated exhaust gas and re-enters the cylinder with the fresh mixed gas for combustion. In this way, the problem of water vapor condensation during the exhaust gas recirculation process is solved, the stability and combustion efficiency of the engine are improved, and the emission of harmful substances is reduced.

[0025] Specifically, Figure 1 It is a block diagram of the engine exhaust treatment structure of an embodiment of the present application.

[0026] like Figure 1 As shown, the engine exhaust treatment structure 10 includes: a power component 100 , an exhaust gas recirculation component 200 , a power battery 300 and an ionization component 400 .

[0027] The ionization component 400 is respectively connected to the power component 100, the exhaust gas recirculation component 200 and the power battery 300, and is used to ionize the circulating exhaust gas of the exhaust gas recirculation component and send the ionized circulating exhaust gas to the power component.

[0028] It can be understood that the exhaust gas recirculation component 200 of the embodiment of the present application is responsible for returning part of the exhaust gas discharged by the engine to the intake manifold to reduce the combustion temperature in the cylinder and reduce the generation of NOx. The ionization component 400 is used to ionize the exhaust gas, decompose the water vapor in the exhaust gas into hydrogen and oxygen, prevent the generation of condensed water, and improve the combustion efficiency of the engine. The power component 100 receives the treated exhaust gas and re-enters the cylinder with the fresh mixed gas for combustion. In this way, the problem of water vapor condensation in the exhaust gas recirculation process is solved, the stability and combustion efficiency of the engine are improved, and the emission of harmful substances is reduced.

[0029] In one embodiment of the present application, Figure 2 As shown, the ionization component 400 includes: a boosting device 401 and an electric shock device 402, wherein the boosting device 401 is connected to the power battery 300, respectively, and is used to increase the voltage of the positive and negative currents generated by the power battery 300; the electric shock device 402 is connected to the boosting device, and is used to generate a high-voltage arc based on the increased voltage to ionize water vapor in the circulating exhaust gas into hydrogen and oxygen.

[0030] The ionization assembly 400 of the embodiment of the present application is a core component, which decomposes the water vapor in the exhaust gas into hydrogen and oxygen by ionizing the exhaust gas, and mainly includes a booster 401 and an electric shock device 402. The booster 401 is connected to the power battery 300, receives the current provided by the battery, and outputs the current to the electric shock device 402 after boosting the voltage. The electric shock device 402 receives the high voltage after boosting, and uses the voltage to generate a high-voltage arc. Among them, the electric shock device 402 is provided with a positive electrode and a negative electrode inside, which is used to generate a high-voltage arc.

[0031] In the actual implementation process, the boost device 401 increases the voltage of the positive and negative currents provided by the power battery 300 to the target voltage value to ensure that an effective high-voltage arc can be generated in the electric shock device 402. The electric shock device 402 generates a high-voltage arc between the positive and negative electrodes based on the high voltage provided by the boost device 401. The energy of the high-voltage arc decomposes the water vapor molecules in the exhaust gas into hydrogen and oxygen. Among them, the target voltage value can be determined according to the exhaust gas flow entering the electric shock device.

[0032] In one embodiment of the present application, the exhaust gas recirculation component 200 includes: a turbine 201, a three-way catalytic converter 202 and an exhaust gas recirculation valve 203, wherein the three-way catalytic converter 202 is connected to the turbine 201 and the exhaust gas recirculation valve 203 respectively, and the exhaust gas recirculation valve 203 is connected to the inlet of the electric shock device 402 for adjusting the flow of circulating exhaust gas entering the electric shock device 402.

[0033] In the actual implementation process, the three-way catalytic converter 202 is further used to: divide the engine exhaust gas into a first branch and a second branch, the first branch discharges a part of the circulating exhaust gas to the outside air, and the second branch directs the other part of the circulating exhaust gas into the electric shock device 401 through the exhaust gas recirculation valve.

[0034] Specifically, the turbine 201 of the embodiment of the present application is used to preliminarily process the exhaust gas discharged by the engine, and the inlet of the three-way catalytic converter 202 is connected to the turbine 201 to receive the exhaust gas processed by the turbine. The main function of the three-way catalytic converter 202 is to purify the exhaust gas and reduce the emission of harmful substances, and to directly discharge a part of the purified exhaust gas into the external atmospheric environment, and to send another part of the purified exhaust gas into the electric shock device 402 through the exhaust gas recirculation valve 203. In the actual implementation process, the exhaust gas recirculation valve 203 can dynamically adjust the exhaust gas flow entering the electric shock device 402 according to the engine operating conditions and the requirements of the control system.

[0035] In one embodiment of the present application, the power assembly 100 includes: a compressor 101, an intercooler 102 and an engine cylinder 103, wherein the inlet of the compressor 101 is connected to the outlet of the electric shock device 402, the outlet of the compressor 101 is connected to the intercooler 102, and the intercooler 102 is connected to the engine cylinder 103.

[0036] In the actual implementation process, the compressor 101 sucks the hydrogen and oxygen output by the electric shock device 402 and the outside air into the intercooler 102. Through compression, the intake density can be increased, thereby increasing the air quality entering the engine cylinder and improving the combustion efficiency. The intercooler 102 cools the hydrogen, oxygen and outside air and sends them to the engine cylinder 103 for combustion. Therefore, by cooling the high-temperature compressed gas coming out of the compressor 101, its temperature is reduced, thereby increasing the intake density and further improving the combustion efficiency.

[0037] According to the engine exhaust treatment structure proposed in the embodiment of the present application, an ionization component is added to ionize the exhaust gas, decompose the water vapor in the exhaust gas, prevent the generation of condensed water, and improve the combustion efficiency of the engine. The power component receives the treated exhaust gas and re-enters the cylinder with the fresh mixed gas for combustion. In this way, the problem of water vapor condensation in the exhaust gas recirculation process is solved, the stability and combustion efficiency of the engine are improved, and the emission of harmful substances is reduced.

[0038] Next, the engine exhaust treatment system proposed according to the embodiment of the present application is described with reference to the accompanying drawings.

[0039] Figure 3 A block diagram of an engine exhaust treatment system provided in an embodiment of the present application.

[0040] like Figure 3 As shown, the engine exhaust treatment system 20 includes: the engine exhaust treatment structure 10 of the above embodiment, a detection component 500 and a controller 600

[0041] Among them, the detection component 500 is used to detect the circulating waste flow entering the motor device; the controller 600 is used to control the motor device to generate a high-voltage arc according to the circulating exhaust gas flow, and ionize the circulating exhaust gas based on the high-voltage arc, and send the ionized circulating exhaust gas into the power component.

[0042] It is understandable that the detection component 500 of the embodiment of the present application monitors the exhaust gas flow entering the electric shock device 402 in real time and transmits the data to the controller 600. The controller 600 dynamically adjusts the output voltage of the boost device 401 according to the detected exhaust gas flow data to ensure that the electric shock device 402 can generate an effective high-voltage arc, thereby achieving precise control of the ionization process and ensuring efficient operation of the system.
