Description

Technical Field

[0001] This invention relates to the field of internal combustion engine technology, and in particular to an intake control method for an internal combustion engine power system, an atomized intake system, and a vehicle. Background Technology

[0002] To improve engine efficiency and stability, water mist is added during the intake process of an internal combustion engine to control the intake air humidity. This achieves numerous benefits through physical cooling and chemical reactions. For example, after the water mist enters the cylinder, it absorbs a large amount of heat, thereby suppressing knocking and improving power output. At the same time, under high temperature and pressure, some water molecules will decompose into hydrogen and oxygen, which will then participate in combustion, ensuring complete combustion of fuel. This helps improve combustion efficiency and reduce carbon deposits, improving fuel economy and reducing emissions, which is beneficial to environmental protection.

[0003] An existing invention patent application with publication number CN119532067A discloses an engine energy-saving device and method for producing hydrogen using ultrasonic water mist and mineral particles. The device includes a dedicated water tank, an ultrasonic water mist generator, and micro-hydrogen-producing mineral particles. The dedicated water tank is divided into an ultrasonic water mist generation chamber and a mineral particle hydrogen production chamber by a permeable partition. The ultrasonic water mist generator is placed 3mm-5mm below the liquid surface in the ultrasonic water mist generation chamber and atomizes water through an external power supply. Micro-hydrogen-producing mineral particles are placed at the bottom of the mineral particle hydrogen production chamber, which react with water to generate hydrogen gas. Some of the hydrogen gas dissolves in the water, and some is stored in a gas storage chamber above the liquid surface. The top of the dedicated water tank has an outlet connected to the engine intake pipe. The water mist and hydrogen gas enter the cylinder with the engine intake air to participate in power generation, thereby eliminating excess fuel injection and reducing in-cylinder heat transfer loss.

[0004] Existing solutions, such as those for water mist input into internal combustion engines, while all reveal the process of atomizing water and introducing it into the engine, generally lack effective mechanisms for filter condition monitoring and lifespan maintenance. This ignores the issue of filter aging due to prolonged use affecting air intake. Since the airflow for water mist input must pass through the filter, even with precise monitoring of engine parameters and accurate atomization control by the atomizer, inaccurate airflow for mist delivery after filter aging can prevent the engine from achieving ideal operating conditions. Therefore, improvements are urgently needed. Summary of the Invention

[0005] In view of this, the present invention proposes an intake control method, atomizing intake system and vehicle for an internal combustion engine power system that can effectively ensure the filter element life and make the mist delivery accurate, so as to solve the problem of inaccurate mist delivery caused by the failure of the prior art to consider the effect of filter element aging.

The multimodal sensor array transmits the data to the atomizer box control chip. Initialize and set the internal combustion engine intake cycle duration T1, backflush cycle duration T2, and filter element moisture threshold H; Start the air supply fan and the mist exhaust fan. The atomizing box continuously generates water mist, and the mist exhaust fan continuously outputs water mist. The water mist is condensed by the condenser and returned to the water tank of the atomizing box. The control chip determines the amount of mist entering the internal combustion engine based on the data transmitted by the multimodal sensor array, and inputs water mist into the intake pipe of the internal combustion engine through the mist intake fan in the manifold. During this process, the mist exhaust fan stops and the outlet of the mist exhaust fan is closed by a valve. When the filter element humidity is ≥H for 5 consecutive seconds, the pressure difference across the filter element is ≥50Pa, or the air intake cycle reaches T1, the air supply fan, mist inlet fan, and mist exhaust fan will stop. The outlets of the mist inlet fan and mist exhaust fan will be closed through valves, and the back-blowing fan will be opened to back-blow the filter element.

[0015] In another aspect, the present invention provides a vehicle including the aforementioned atomizing air intake system.

[0016] The internal combustion engine power system intake control method, atomized intake system, and vehicle of the present invention have the following advantages over the prior art: (1) By constructing a multi-modal array sensor, it can collect the intake air temperature, intake air humidity, intake air flow, exhaust temperature and fuel injection pulse width signals of the internal combustion engine, and transmit the data to the control chip of the atomizing box. In this way, the target atomization volume required by the internal combustion engine can be calculated. At the same time, this solution also collects the internal temperature of the atomizing box, filter element humidity, filter element temperature and pressure difference data. This can realize the working condition detection of the filter element, so as to control the operation of the atomizing box according to the working condition, ensure the accurate intake volume, and accurately carry water mist into the engine, thereby ensuring the working condition of the internal combustion engine and helping to ensure the service life of the filter element. (2) In this control method, the atomizing box continuously generates water mist, which is circulated through the condenser. Only when it is necessary to humidify the intake air of the internal combustion engine, the exhaust fan will stop working, and the circulated water mist will enter the internal combustion engine under the drive of the inlet fan in the manifold. This avoids the delay in fogging, and the water mist has a shorter path to enter the internal combustion engine, which optimizes the air supply efficiency and makes the adjustment of the combustion operation of the internal combustion engine more timely. (3) In this control method, by calculating the remaining life of the filter element, predicting the life of the filter element, dynamically optimizing the backflushing cycle, and compensating the backflushing intensity for the filter element temperature, the service life of the filter element can be effectively improved, while reducing energy consumption and reducing sudden failures and maintenance costs. Because it effectively controls the working conditions of the filter element, the control of the intake air humidity of the internal combustion engine is more precise, which helps to ensure complete fuel combustion. (4) In the air intake system of the present invention, an atomizing module and an air intake module are provided. The atomizing module and the air intake module are connected by an elastic connecting pipe with elasticity. At the same time, the atomizing module is connected to the bracket by a sliding component and supported by an elastic seat. In this way, when vibration is caused by factors such as vehicle driving, the atomizing module can float up and down to buffer by relying on the buffer of the elastic seat, which can avoid the coupling effect between external vibration and ultrasonic atomization and reduce liquid surface vibration, so as to ensure ultrasonic energy transmission efficiency and thus ensure a stable atomization output. (5) Heating pipes are provided in the atomization module and the intake module. Firstly, the heating pipes can heat the water and water mist in the atomization module, thereby avoiding the freezing problem in low temperature environment and also avoiding the condensation rate of water mist in the intake pipe of the internal combustion engine, so as to ensure the stable input of water mist. Secondly, the heating pipes can heat the gas in the atomization module and the intake module, so as to improve the impurity desorption ability and ensure cleaning efficiency during backflushing. Thirdly, the heat of the heating pipes can continue to diffuse through the heat conduction pipe, thereby avoiding the failure or slow response of the elastic seat in low temperature environment, and thus ensuring the good working condition of this intake system. (6) The heating pipe of this atomizing air intake system adopts an integrated structure design. It is distributed in the atomizing module and the air intake module in a through structure, which effectively reduces the integration difficulty. At the same time, the heating pipe can heat the filter element, which can not only optimize the air intake temperature, but also improve the back-flushing drying effect, thus ensuring the integration of functions.

Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0025] like Figures 1-8 As shown, the atomizing air intake system of the present invention includes an atomizing box 100, an internal combustion engine intake pipe 200, and an internal combustion engine 300. The atomizing port of the atomizing box 100 is connected to the middle section of the internal combustion engine intake pipe 200; the air intake port of the internal combustion engine 300 is connected to one end of the internal combustion engine intake pipe 200, and the other end of the internal combustion engine intake pipe 200 is a free end. As described above, the atomizing box 100 is used to generate water mist, and the internal combustion engine intake pipe 200 is used to input gas into the internal combustion engine 300 for combustion. During the intake process of the internal combustion engine 300, the water mist generated by the atomizing box 100 enters the internal combustion engine 300 through the internal combustion engine intake pipe 200 to promote combustion efficiency and achieve technical effects such as cooling and suppressing knocking.

[0026] like Figures 2-5 As shown, the atomizing box 100 includes a support 1, an atomizing module 2, an air intake module 3, an elastic connecting tube 4, and an elastic seat 5. The support 1 is L-shaped, and a sliding component 11 is provided inside one side of the support 1. The atomizing module 2 is connected to the sliding component 11. The air intake module 3 is connected to the side of the support 1 where the sliding component 11 is located, and the atomizing module 2 is closer to the other side of the support 1 than the air intake module 3. The elastic connecting tube 4 is located between the atomizing module 2 and the air intake module 3, with one end of the elastic connecting tube 4 connected to the atomizing module 2 and the other end connected to the air intake module 3. One end of the elastic seat 5 is connected to the atomizing module 2, and the other end of the elastic seat 5 is connected to the side of the support 1 away from the sliding component 11. As described above, bracket 1 is used to connect the vehicle, and atomizing module 2 and air intake module 3 are mounted on bracket 1. The atomizing module 2 needs to store water and generate water mist. Therefore, the atomizing module 2 is connected to the bracket 1 through the sliding component 11, and the bottom of the atomizing module 2 is connected to the bracket 1 through the elastic seat 5 to achieve buffering. In this way, when vibration is caused by factors such as vehicle movement, the atomizing module 2 can float up and down to buffer the vibration by relying on the buffer of the elastic seat 5. This can avoid the coupling effect between external vibration and ultrasonic atomization, and can reduce liquid surface vibration to ensure ultrasonic energy transmission efficiency, thereby ensuring a stable atomization output. The air intake module 3 is used for air intake to drive the airflow to carry water mist for delivery. The air intake module 3 is fixedly connected to the bracket 1. Since the air intake module 3 needs to be connected to the atomizing module 2, the atomizing module 2 is connected by an elastic connecting pipe 4. In this way, even if the atomizing module 2 moves up and down due to vibration, it will not disconnect from the air intake module 3, thus ensuring good airflow. Preferably, the flexible connecting pipe 4 is a corrugated pipe, and a membrane layer is set inside the corrugated pipe to seal the tortuous surface of the corrugated pipe, thereby ensuring the smooth flow of air.

[0027] like Figure 6 and Figure 7As shown, the air intake module 3 includes a first housing 31, a filter element 32, an air supply fan 33, an isolation power supply 34, an air box 35, an air inlet 36, an air outlet 37, and a back-blowing fan 38. The first housing 31 is connected to the bracket 1, and a temperature sensor is installed inside the first housing 31. The filter element 32 is installed inside the first housing 31, corresponding to the air box 35. Differential pressure sensors are installed on both the air inlet and outlet sides of the filter element 32, and a humidity sensor and a temperature sensor are embedded inside the filter element 32. The air supply fan 33 is located on one side of the filter element 32. The isolation power supply 34 is located inside the first housing 31. The air box 35 is located on the outer wall of the first housing 31 and is connected to the first housing 31. The air inlet 36 and the air outlet 37 are both connected to the air box 35, and both the air inlet 36 and the air outlet 37 are equipped with switching valves. The back-blowing fan 38 is located inside the air outlet 37. As described above, the intake module 3 is used for airflow input, which carries water mist into the engine. The first box 31 serves as a carrier for mounting other components; The air box 35 is connected to the first box 31, and the air box 35 is provided with an air inlet 36. The first box 31 is provided with a filter element 32. So that after the external airflow enters the air box 35, it will be filtered by the filter element 32 before entering the first box 31, so as to avoid external impurities from entering and affecting the combustion gas supply of the internal combustion engine. The air supply fan 33 is located on one side of the filter element 32. When it is necessary to input airflow to carry water mist, the air supply fan 33 is started to generate negative pressure so that airflow can be input through the air inlet 36. The air box 35 is also equipped with an exhaust port 37, and a back-blowing fan 38 is installed inside the exhaust port 37. When the filter element needs to be back-blown to clean debris or dry, the air supply fan 33 stops and the back-blowing fan 38 starts to draw air outward, thereby realizing the back-blowing cleaning and drying of the filter element 32. In order to avoid the air inlet 36 and the exhaust port 37 from affecting the normal flow of air, both the air inlet 36 and the exhaust port 37 are equipped with on / off valves for on / off control. The first housing 31 is equipped with a temperature sensor to detect the temperature of the input airflow. Since the water and airflow used to prepare the water mist are at basically the same temperature, the temperature sensor can be used for temperature detection. Furthermore, a temperature sensor is also installed in the intake pipe 200 of the internal combustion engine. This allows for a comprehensive judgment of the intake temperature of the internal combustion engine 300. The temperature data can then be used as a reference to adaptively adjust the water mist supply of the internal combustion engine 300. The filter element 32 is equipped with differential pressure sensors on both the inlet and outlet sides, and a humidity sensor and a temperature sensor are embedded inside the filter element 32. Through the differential pressure sensor, humidity sensor and temperature sensor, the working condition of the filter element 32 can be effectively judged by the pressure difference change. At the same time, the humidity data and temperature data of the filter element 32 can also be obtained. This allows the input size of the water mist flow to be determined, which facilitates the subsequent adjustment of the power of the air supply fan 33 to achieve a stable and accurate input of water mist into the internal combustion engine 300. Furthermore, the humidity data from the humidity sensor and the temperature data from the temperature sensor can help determine the differential pressure data of the filter element 32, and also determine the condition of the filter element 32 itself. This data is helpful for predicting the service life of the filter element 32 and adjusting the backflushing cycle, which helps reduce maintenance costs and reduce sudden failures. The isolation power supply 34 is used for the electrical connection of various electrical components to supply electrical energy, such as connecting various fans.

[0028] In some embodiments, if the filter element 32 is damp during long-term use, a humidity sensor is added to the first housing 31 to detect the humidity of the input airflow, thereby controlling the amount of air entering the internal combustion engine intake pipe 200; a humidity sensor is also provided in the internal combustion engine intake pipe 200.

[0029] like Figure 6 and Figure 7 As shown, the atomizing module 2 includes a second housing 21, an ultrasonic atomizing component 22, a return mist pipe 23, a manifold 24, a back-blowing air inlet pipe 25, a partition plate 26, an exhaust fan 27, an inlet fan 28, and a water baffle 29. The second housing 21 is connected to the sliding component 11 and the elastic seat 5. The second housing 21 is connected to the first housing 31 through an elastic connecting pipe 4. A heat-conducting pipe 211 is provided at the bottom of the second housing 21. One end of the heat-conducting pipe 211 is connected to the second housing 21, and the other end of the heat-conducting pipe 211 surrounds the elastic seat 5. The heat-conducting pipe 211 is spaced apart from the support 1. The support 1 has a groove plate structure to form an L-shaped flow channel. The heat-conducting pipe 211 and the elastic seat 5 are located in the L-shaped flow channel. As described above, the second box 21 is used to accommodate other components. The second box 21 is connected to the support 1 via the sliding component 11 so that it can float up and down during vibration. At the same time, the second box 21 is made with an elastic seat 5 to achieve a vibration reduction and buffering effect. The second housing 21 of the atomizing module 2 also contains water for atomization. To prevent the water from freezing in low-temperature environments, a heating component is installed inside to heat the water. Specifically, a heat pipe 211 is provided at the bottom of the second box 21, and the heat pipe 211 surrounds the elastic seat 5. In this way, after the water is heated, the heat will be transferred to the second box 21, and then the heat will be transferred to the heat pipe 211. At this time, the heat pipe 211 heats the surrounding gas, which helps to increase the temperature of the elastic seat 5, so as to avoid the problem of failure and slow response of the elastic seat 5 in low temperature environment. Specifically, the bracket 1 is designed in an L-shape, which facilitates the installation of the atomizing module 2 and the air intake module 3, and also enables connection with the elastic seat 5. At the same time, the bracket 1 forms an L-shaped flow channel. In some embodiments, the vehicle's air conditioning flow channel leads out to the corresponding L-shaped flow channel, thereby drawing out cold air in a high-temperature environment to cool the elastic seat 5 and ensure the working condition of the elastic seat 5.

[0030] like Figure 7 As shown, the ultrasonic atomizing component 22 is disposed inside the second housing 21, and the ultrasonic atomizing component 22 is located at the bottom of the second housing 21; one end of the return mist pipe 23, the manifold 24, and the backflush air intake pipe 25 are all connected to the second housing 21, and the other end of the return mist pipe 23, the manifold 24, and the backflush air intake pipe 25 are all free ends; the de-fogging fan 27 is disposed inside the return mist pipe 23; the de-fogging fan 28 is disposed inside the manifold 24. As described above, the ultrasonic atomizing component 22 is disposed inside the second housing 21 and is used for water atomization. After the water is atomized, it is guided by the continuous airflow input from the air supply fan 33 and the continuous airflow output from the mist exhaust fan 27 in the return mist pipe 23, and the water mist will be continuously output through the return mist pipe 23. Specifically, the return mist pipe 23 is connected to a condenser to condense the water mist and return it to the second housing 21, thereby realizing the real-time preparation of water mist. When humidity compensation is required for the internal combustion engine intake manifold 200, the de-fogging fan 27 stops, and the intake fan 28 in the manifold 24 starts. The intake fan 28 carries the water mist into the internal combustion engine intake manifold 200 and then into the internal combustion engine 300. When it is necessary to backflush the filter element 32, the air supply fan 33, the de-fogging fan 27, and the mist inlet fan 28 all stop working. At this time, the backflush air inlet pipe 25 is opened and the backflush fan 38 is opened to achieve backflushing of the filter element 32.

[0031] In some embodiments, instead of a mist inlet fan 28, an air compressor is provided. The air compressor has the functions of compressing air, storing air, and releasing air. The air outlet of the air compressor corresponds to the manifold 24 and is equipped with a switch valve. In this way, the air compressor compresses air in advance, and when water mist needs to be supplied, the switch valve can be opened. Compared with the mist inlet fan 28, it has the advantage of faster response speed.

[0032] like Figure 7As shown, the partition plate 26 has a connecting portion 261 extending into the second box 21. The connecting portion 261 extends to both sides within the second box 21 to form a first windbreak portion 262 and a second windbreak portion 263. The first windbreak portion 262 corresponds to the inlet of the elastic connecting pipe 4, and the second windbreak portion 263 corresponds to the inlet of the manifold 24 and the backflush air inlet pipe 25. The end of the second windbreak portion 263 corresponds to the return mist pipe 23. The water baffle 29 is disposed within the second box 21 and is arranged in a stepped manner. As described above, the partition plate 26 is used to separate the internal space of the second box 21 to form a flow channel for airflow. Furthermore, the connecting portion 261 of the partition plate 26 extends into the second housing 21, forming a first windbreak portion 262 and a second windbreak portion 263. Thus, during air intake, the first windbreak portion 262 prevents the airflow from directly blowing onto the ultrasonic atomizing component 22, thereby ensuring the stability of water mist preparation. The second windbreak portion 263 allows the water mist to be stably output through the return mist pipe 23. That is, when the water mist is circulating, the water mist will only flow through the lower side of the second windbreak portion 263 to avoid interference from the back-blowing air intake pipe 25 and manifold 24. The water baffle 29 is used to block water to prevent excessive water accumulation on the ultrasonic atomizing component 22 from affecting the normal preparation of water mist. Specifically, the water baffle 29 is set with a stepped structure to reduce the impact on the input airflow.

[0033] like Figures 2-8 As shown, it also includes a heating element 6, which includes a coiled portion 61, a connecting section 62, and a heat dissipation plate 63. The coiled portion 61 is disposed inside the second housing 21 and surrounds the ultrasonic atomizing component 22. The coiled portion 61 has a heat medium inlet and a heat medium outlet. Both ends of the connecting section 62 are connected to the coiled portion 61. One end of the connecting section 62 is connected to the inlet of the coiled portion 61, and the other end of the connecting section 62 is connected to the outlet of the coiled portion 61. The connecting section 62 bends through the elastic connecting tube 4 and is introduced into the first housing 31. The portion of the connecting section 62 located inside the first housing 31 is provided with an outlet tube 621. One end of the outlet tube 621 is connected to the connecting section 62, and the other end of the outlet tube 621 extends to the outside of the first housing 31 and corresponds to the back-blowing air inlet tube 25. One end of the heat dissipation plate 63 is attached to the connecting section 62, and the other end of the heat dissipation plate 63 is embedded in the filter element 32. As described above, the heating element 6 is used to heat the water in the second housing 21, and also provides heat to the heating elastic seat 5 and the drying filter element 32; the heating element 6 includes a coiled part 61, a connecting section 62 and a heat dissipation plate 63. The coiled part 61 is located inside the second box 21 and is surrounded by the ultrasonic atomizing component 22. The water can be atomized by the ultrasonic atomizing component 22 after heating, which can avoid the freezing problem in low temperature environment and also avoid the condensation rate of water mist in the intake pipe 200 of the internal combustion engine, so as to ensure the stable input of water mist. Meanwhile, since the coiled part 61 heats the water, the heat will be transferred to the second box 21. The heat from the heating pipe can continue to diffuse through the heat conduction pipe 211 to heat the surrounding gas, thereby avoiding the failure or slow response of the elastic seat 5 in the low temperature environment, thus ensuring the good working condition of this air intake system. Among them, the connecting section 62 can heat the gas in the atomization module and the intake module, so that the impurity desorption capacity can be improved during backflushing and the cleaning efficiency can be ensured; at the same time, it can also adjust the temperature of the airflow input to the air supply fan 33 so that the temperature of the water-carrying mist can meet the working conditions of the internal combustion engine 300 after carrying water mist. The filter element 32 has a heat dissipation plate 63 inside, which is fitted to the connecting section 62. The connecting section 62 and the heat dissipation plate 63 are separate structures, so the heat dissipation plate 63 can be integrated with the filter element 32. When assembling the filter element 32, the heat dissipation plate 63 can be fitted to the connecting section 62, which improves the convenience of integration. In practical applications, this structure allows the heating element 6 to heat the filter element 32, thereby improving the drying efficiency and ensuring the service life of the filter element 32. The connecting section 62 is provided with an outlet pipe 621, and the outlet of the outlet pipe 621 corresponds to the backflush intake pipe 25. Thus, when the filter element 32 needs to be backflushed, the filter element 32 can be backflushed directly by the hot airflow output from the outlet pipe 621. Under this condition, the heating medium in the heating pipe 6 is gas, such as the airflow after heat exchange with the engine exhaust, to achieve the heat supply of the heating pipe 6. The heating medium inlet and outlet are both located on the coiled part 61 to improve the convenience of pipeline connection and integration.

[0034] like Figure 7 and Figure 8 As shown, the connecting segment 62 extends from the second box 21 into the first box 31. The connecting segment 62 has a three-section bending structure. The part located inside the second box 21 has a horizontally arranged section, which is set as an elastic section. Alternatively, the corner point of the connecting segment 62 can be set as an elastic structure to compensate for the relative displacement between the second box 21 and the first box 31 during vibration.

[0035] The vehicle of the present invention includes the above-described atomizing air intake system.

[0036] The intake control method for an internal combustion engine power system of the present invention includes the following steps: A multimodal sensor array is constructed to synchronously collect data on the intake air temperature, intake air humidity, intake air flow, exhaust air temperature, fuel injection pulse width signal, atomizer box internal temperature, filter element humidity, filter element temperature and differential pressure at a sampling frequency of 100Hz. The multimodal sensor array transmits the data to the atomizer box control chip. Initialize and set the internal combustion engine intake cycle duration T1, backflush cycle duration T2, and filter element moisture threshold H; Start the air supply fan and the mist exhaust fan. The atomizing box continuously generates water mist, and the mist exhaust fan continuously outputs water mist. The water mist is condensed by the condenser and returned to the water tank of the atomizing box. The control chip determines the amount of mist entering the internal combustion engine based on the data transmitted by the multimodal sensor array, and inputs water mist into the intake pipe of the internal combustion engine through the mist intake fan in the manifold. During this process, the mist exhaust fan stops and the outlet of the mist exhaust fan is closed by a valve. When the filter element humidity is ≥H for 5 consecutive seconds, the pressure difference across the filter element is ≥50Pa, or the air intake cycle reaches T1, the air supply fan, mist inlet fan, and mist exhaust fan will stop. The outlets of the mist inlet fan and mist exhaust fan will be closed through valves, and the back-blowing fan will be opened to back-blow the filter element.

[0037] As described above, this intake control method collects the intake air temperature, intake air humidity, intake air flow, exhaust air temperature and fuel injection pulse width signals of the internal combustion engine, and transmits the data to the control chip of the atomizing box 100. In this way, the target atomization amount required by the internal combustion engine 300 can be calculated. In this scheme, water mist is continuously generated. When mist is needed, the exhaust fan 27 stops, and the mist intake fan 28 in the manifold 24 starts. The mist intake fan 28 carries the airflow carrying water mist into the intake pipe 200 of the internal combustion engine, and then into the internal combustion engine 300. This control process does not affect the operation of the ultrasonic atomizing component 22, which helps to ensure sufficient mist volume and improve response speed. Furthermore, the vehicle is equipped with a humidity sensor to monitor changes in external humidity in real time, thereby controlling the atomizing box to start producing mist in advance to avoid energy waste caused by starting too early. It can be turned on a period of time before the internal combustion engine needs to supply water mist.

[0038] Meanwhile, this solution also collects data on the internal temperature of the atomizing box 100, the humidity of the filter element, the temperature of the filter element, and the pressure difference. This enables the detection of the working condition of the filter element 32, so as to control the operation of the atomizing box 100 according to the working condition, ensure accurate air intake, and accurately carry water mist into the engine, thereby ensuring the working condition of the internal combustion engine. In this solution, the intake cycle duration T1 of the internal combustion engine, the backflush cycle duration T2, and the filter element moisture threshold H are preset. Once any of the above conditions are met, the backflush function of the filter element 32 is activated, thereby ensuring the service life of the filter element 32 and guaranteeing that the filter element 32 has good working conditions during application.

[0039] In this control method, the filter element health is calculated in real time. Actual observed lifespan can be inferred from health status. and the predicted remaining life of the filter cartridge. Comparative analysis is conducted; based on the difference between prediction and observation, the lifespan model parameters are adaptively updated to achieve the remaining lifespan of the filter element. Accurate predictions.

[0040] , in, This refers to the actual observed lifespan of filter element 32; This is the initial design life of filter element 32; The health index of filter element 32.

[0041] Specifically, in this control method, the formula for calculating filter element health is as follows: +0.3 +0.3 , in, The health index of the filter element; This represents the initial pressure difference of the filter element; This represents the current pressure difference of the filter element; This is the initial flow rate of the filter element; This represents the current flow rate of the filter element. This refers to the initial filtration efficiency of the filter element. The current filtration efficiency of the filter element is 0.4; the pressure difference weight is 0.4, and the flow rate weight and efficiency weight are 0.3. The weighting coefficients can be adjusted according to the importance of the parameters. As described above, the health calculation module serves as the system's sensing foundation. It uses a multimodal sensor array to collect key parameters such as pressure difference changes, flow rate attenuation, and filtration efficiency of filter element 32 in real time, and comprehensively calculates quantitative indicators reflecting the current health status of the filter element. Specifically, flow rate attenuation is correlated with pressure difference changes and these are detected simultaneously. The filtration efficiency detection response is handled by sensors, such as particle sensors. This health level provides a realistic calibration benchmark for remaining life prediction, ensuring that the life prediction model is always based on actual operating data rather than purely theoretical calculations. Continuous monitoring of the health level provides dynamically changing input for life prediction, enabling the prediction results to reflect the actual degradation of the filter element in a timely manner.

[0042] Furthermore, based on the Arrhenius equation and Miner's linear cumulative damage theory, a formula for calculating the remaining life of the filter element is established by coupling multiple parameters. , in, Predict the remaining life of the filter element; This refers to the initial design life of the filter element; It is a constant, with a value of 2.71828; This represents the backflush damage coefficient. This refers to the temperature aging coefficient. The coupling damage coefficient; To accumulate backflush counts; This represents the average temperature inside the atomizing chamber. As described above, this scheme is used to calculate the remaining lifespan of filter element 32. The lifespan of filter element 32 is mainly affected by thermal aging and mechanical fatigue. Therefore, when calculating the remaining lifespan of filter element 32, these factors are taken into account. This multi-parameter coupled lifespan model is used to calculate the remaining lifespan of filter element 32, providing a control basis for each module, such as adjusting parameters like temperature and backflushing intensity based on the predicted lifespan. This scheme reflects the remaining lifespan of filter element 32 based on a value at a certain moment. This value is compared with the actual observed lifespan to drive the model to perform adaptive correction, and also provides a benchmark value for optimizing the backflushing strategy.

[0043] The adaptive lifetime model update formula is as follows: , in, This is the corrected backflush damage coefficient; The damage coefficient currently in use; This is the predicted lifespan of the filter element; 1 represents the actual observed lifespan of filter element 32; 1 is the baseline coefficient; 0.1 is the learning rate coefficient.

[0044] This solution uses an adaptive lifespan model update formula and achieves autonomous evolution of model parameters through a data-driven closed loop. By comparing the predicted lifespan with the actual observed lifespan, this solution automatically corrects the backflush damage coefficient and temperature aging coefficient, which can effectively reduce prediction errors and achieve accurate perception of filter lifespan.

[0045] Furthermore, this method dynamically optimizes the backflushing cycle and introduces a temperature compensation mechanism to ensure that the backflushing operation matches the actual working conditions, so that the filter element 32 maintains its optimal condition throughout its entire lifespan and is conducive to extending the lifespan of the filter element 32. Specifically, based on the predicted lifespan of filter element 32, the backflushing cycle is dynamically optimized, the backflushing intensity is compensated by the temperature of filter element 32, the health index of filter element 32 is calculated, the health status of filter element is evaluated in real time, and the adaptive lifespan model is updated, thereby realizing closed-loop control of filter element 32 in application. The dynamic optimization formula for the backflush cycle is as follows: = , in, The optimized backflush cycle duration; Basic backflush cycle; This is the adaptive adjustment coefficient, with a value of 0.3. Predict the remaining life of the filter element; This refers to the initial design life of the filter element; Backflush strength compensation formula is , in, The reverse airflow speed after compensation for the reverse airflow; The base reverse airflow speed for the reverse air blower; 1 represents the temperature of the filter element; 1 represents the reference coefficient; 0.002 represents the temperature compensation coefficient; and 25 represents the reference reference temperature.

[0046] As described above, this method is based on the accurate prediction of the filter element's lifespan. The system dynamically optimizes the backflushing cycle and introduces a temperature compensation mechanism as an execution and feedback link to ensure that the control strategy matches the filter element's state. The operating status data is further collected and fed back through a multi-modal sensor array to generate new observed lifespans, providing real data for model evolution and driving continuous closed-loop optimization. This solution correlates material fatigue data with data collected by multimodal sensors to establish a dynamic prediction model. At the same time, through the backflushing intensity temperature compensation formula and continuous dynamic optimization, it can solve environmental factors. While ensuring the service life of the filter element, it also ensures the intake volume of the internal combustion engine, which not only reduces maintenance costs but also ensures the combustion efficiency and good operating conditions of the engine.
