Description

Technical Field

[0002] With the increase in the use of internal combustion engines, petrochemical fuels, as their main energy source, are facing serious problems such as increasing shortages and rising costs. At the same time, the exhaust gas emitted during the operation of internal combustion engines is increasingly deteriorating the environment. Nowadays, in order to further save oil resources, reduce fuel usage costs, and reduce emission pollution, many new technologies and devices for energy saving and emission reduction of internal combustion engines have emerged on the basis of continuously optimizing the technical performance of the internal combustion engine itself, especially the hydrogen and oxygen mixing auxiliary fuel saving and emission reduction technology and its device for automotive internal combustion engines are the most representative.

[0003] In the prior art, hydrogen and oxygen gas is introduced into the cylinder of the internal combustion engine through the vehicle intake pipe by means of the energy-saving and emission-reduction device for the internal combustion engine for vehicles. The hydrogen gas has good diffusion and fast combustion speed. After being fully mixed with the compressed air and fuel in the cylinder, the combustion is more complete and the explosive force is increased, thereby improving the fuel combustion efficiency and achieving the effect of saving fuel and reducing emissions. The existing energy-saving and emission-reduction device for the internal combustion engine for vehicles produces hydrogen and oxygen gas through a water electrolyzer (hydrogen and oxygen generator), and uses a liquid storage tank with a common structure to collect the high-temperature electrolyte of the gas-liquid mixture that undergoes electrochemical reaction in the water electrolyzer. During the driving process of the vehicle, as the vehicle speed and road conditions change, the electrolyte in the liquid storage tank will shake and the liquid level will fluctuate up and down, resulting in the inability of the pressure and liquid level monitoring sensor device in the liquid storage tank to normally, objectively or accurately feedback signal data. Therefore, it is particularly important to seek a sway-resistant circulation liquid storage tank for a hydrogen and oxygen generator for vehicles that prevents the shaking of the liquid in the tank, the fluctuation of the liquid level, and avoids detection errors.

[0081] When the staff puts the desiccant 404.21 into the gas drying device kettle body 404.1, the gas drying device kettle body 404.1 needs to be placed upside down, and the first partition plate 404.18 of the gas drying device is used to prevent the desiccant 404.21 from entering the central air chamber 404.4 of the gas drying device. The second partition plate 404.19 of the gas drying device makes the gas drying device air inlet chamber 404.12 form an independent water accumulation space, and prevents the desiccant 404.21 from entering the gas drying device air inlet chamber 404.12. The fourth partition plate 404.21 of the gas drying device is used to block the desiccant 404.21 from entering the upper cavity of the gas drying device outlet chamber 404.13 to prevent the desiccant 404.21 from blocking the gas drying device outlet port 404.6. The third partition plate 404.20 of the gas drying device is used to block the desiccant 404.21 in the corresponding gas drying device air chamber 404.14 from entering the gas drying device inlet chamber 404.12 to prevent the desiccant 404.21 from blocking the gas drying device inlet port 404.5.

[0082] Gas drying device sealing gaskets 404.22 are provided between the top and bottom ends of the gas drying device body 404.1 and the gas drying device upper cover 404.2 and the gas drying device lower cover 404.3 respectively;

[0083] The upper and lower end surfaces of the central air chamber 404.4 of the gas drying device, the air inlet chamber 404.12 of the gas drying device, the air outlet chamber 404.13 of the gas drying device, and the air chamber 404.14 of the gas drying device are all provided with gas drying device sealing strips 404.23. The independence of each air chamber is ensured by the sealing cooperation between the gas drying device sealing strips 404.23 and the gas drying device sealing gaskets 404.22.

[0084] The working principle of the gas drying device 404 is as follows: the hydrogen and oxygen gas with water vapor enters the gas drying device air inlet chamber 404.12 through the gas drying device air inlet port 404.5, and part of the water vapor is cooled to form small water droplets and deposited in the gas drying device air inlet chamber 404.12. The hydrogen and oxygen gas with water vapor flows up and down in an S shape through the first notch 404.10 and the second notch 404.11 of the gas drying device, and then flows through the gas drying device air chamber 404.14 of the rear section of the gas drying device kettle body 404.1, and then flows through the fourth notch 404.10 of the gas drying device. 4.16 enters the central air chamber 404.4 of the gas drying device, enters the air chamber 404.14 of the gas drying device adjacent to the front side of the air inlet chamber 404.12 of the gas drying device through the third notch 404.15 of the gas drying device, flows up and down in an S shape through the first notch 404.10 of the gas drying device and the second notch 404.11 of the gas drying device through the air chamber 404.14 of the front section of the gas drying device kettle body 404.1, and finally enters the air outlet chamber 404.13 of the gas drying device, and is output through the air outlet 404.6 of the gas drying device. When the desiccant 404.21 fails or the drying capacity is insufficient, the water vapor in the hydrogen and oxygen gas cannot be sucked out in time. Over time, the water level in the central air chamber 404.4 of the gas drying device gradually rises. When the float in the gas drying device liquid level sensor 404.17 reaches the high liquid level, the gas drying device liquid level sensor 404.17 feeds back a signal to the control unit 100, starts the alarm function and triggers further protection measures. The gas drying device 404 has both gas drying and failure alarm functions. While ensuring a small size, it increases the effective path and area of ​​contact between the desiccant and the gas, prolongs the replacement cycle of the desiccant, and its structural design facilitates the replacement of the desiccant. When the desiccant fails or the drying capacity is insufficient, it can automatically alarm and trigger further protection measures.

[0086] The liquid replenishing tank body 405.1 is filled with raw water at room temperature, and the cooling spiral tube 405.4 is immersed in the raw water at room temperature.

[0087] The connection relationship between the water electrolyzer 401, the circulating liquid storage tank 402, the gas cooling and water filtering device 403, the gas drying device 404 and the liquid replenishing tank 405 is as follows:

[0088] The water electrolyzer gas outlet 401.11 is connected to the circulating liquid storage tank gas inlet 402.8 via a first pipeline, the circulating liquid storage tank gas outlet 402.9 is connected to the gas cooling water filter device gas inlet 403.2 via a second pipeline, the gas cooling water filter device gas outlet 403.3 is connected to the gas drying device gas inlet 404.5 via a third pipeline, the gas drying device gas outlet 404.6 introduces the dried hydrogen and oxygen gas into the intake pipe of the engine 102, and the gas cooling water filter device liquid return port 403.4, the liquid outlet 402.10 of the circulating liquid storage tank and the liquid inlet 405.5 of the cooling spiral tube are connected by a fourth pipeline, the liquid outlet 405.6 of the cooling spiral tube and the liquid return port 401.9 of the water electrolyzer are connected by a fifth pipeline, the liquid discharge port 401.10 of the water electrolyzer is connected with a liquid discharge valve 406 through a sixth pipeline, the water outlet 405.3 of the liquid replenishing tank and the bottom end of the liquid adding pipe 402.13 of the circulating liquid storage tank are connected by a seventh pipeline, and a water adding pump 407 and an electric stop valve 408 are arranged on the seventh pipeline.

[0089] Working principle of a fuel saving and emission reduction device for a vehicle internal combustion engine:

[0090] The water electrolyzer 401 starts to electrolyze water and generates hydrogen and oxygen gas with water vapor in time. The hydrogen and oxygen gas with water vapor gathers at the top and enters the circulating liquid storage tank 402 from the water electrolyzer outlet 401.11 through the first pipeline through the circulating liquid storage tank inlet 402.8. After passing through the electrolyte in the circulating liquid storage tank 402, it gathers at the top of the circulating liquid storage tank 402 and enters from the circulating liquid storage tank outlet 402.9 through the second pipeline through the gas cooling water filter inlet 403.2. The hydrogen and oxygen gases are then introduced into the gas cooling and water filtering device 403. The cooled hydrogen and oxygen gases are introduced into the gas drying device 404 from the gas cooling and water filtering device outlet 403.3 through the third pipeline and the gas drying device inlet 404.5. The hydrogen and oxygen gases are dried by the desiccant 404.21 in the drying device 404. The dried hydrogen and oxygen gases are then outputted from the gas drying device outlet 404.6 to the intake pipe of the engine 102, and finally enter the engine cylinder along with the air.

[0091] When the hydrogen and oxygen gas with water vapor enters the gas cooling water filter device 403, the water vapor is cooled and condensed into liquid, and gathers at the bottom of the gas cooling water filter device 403, and enters the cooling spiral tube 405.4 through the gas cooling water filter device liquid return port 403.4 through the fourth pipeline and the cooling spiral tube liquid inlet 405.5, and flows back to the water electrolyzer 401 through the cooling spiral tube liquid outlet 405.6 through the fifth pipeline and the water electrolyzer liquid return port 401.9;

[0092] Since a large amount of heat energy is released during the electrochemical reaction of water electrolysis, the temperature of the electrolyte in the water electrolyzer 401 continues to rise. The hydrogen and oxygen gases generated in the water electrolyzer 401 enter the circulating liquid storage tank 402 from the water electrolyzer outlet 401.11 through the first pipeline and the circulating liquid storage tank air inlet 402.8. At the same time, due to the internal pressure and airflow of the water electrolyzer 401, the high-temperature electrolyte in the upper part of the water electrolyzer 401 is brought into the circulating liquid storage tank 402 in the form of a gas-liquid mixture. After the electrolyte in the circulating liquid storage tank 402 is slightly cooled, it enters the cooling spiral tube 405.4 from the circulating liquid storage tank outlet 402.10 through the fourth pipeline and the cooling spiral tube inlet 405.5 under the action of its own gravity. Since the replenishing tank 405 is filled with room temperature raw water, the high temperature electrolyte in the cooling spiral tube 405.4 can be fully cooled, and the cooled electrolyte flows back to the water electrolyzer 401 through the cooling spiral tube outlet 405.6 and the fifth pipeline through the water electrolyzer return port 401.9 for electrolysis reaction. The cooling cycle continues in this way.

[0093] As the electrolysis reaction continues, the electrolyte in the water electrolytic cell 401 is continuously consumed, causing the electrolyte level in the circulating liquid storage tank 402 to continuously drop. When the electrolyte level drops to a set low level, an alarm signal is triggered, and the control unit 200 controls the water pump 407 to start, and at the same time controls the electric stop valve 408 to open, and the room temperature raw water in the replenishment tank 405 is pumped into the circulating liquid storage tank 402 through the replenishment tank outlet 405.3 and the seventh pipeline from the bottom end of the circulating liquid storage tank replenishment pipe 402.13. As the liquid level in the circulating liquid storage tank 402 rises, when the liquid level reaches a set high level, an alarm signal is triggered, and the control unit 200 controls the water pump 407 to close, and at the same time controls the electric stop valve 408 to close, and water addition stops.

[0094] During the output process of hydrogen and oxygen gas, if the pipeline is blocked, resulting in poor gas output, the gas pressure in the circulating liquid storage tank 402 and the gas cooling and water filtering device 403 will continue to increase. The circulating liquid storage tank pressure sensor 402.14 is used to monitor the gas pressure change in the circulating liquid storage tank 402 in real time. When the gas pressure in the circulating liquid storage tank 402 reaches the alarm upper limit pressure value, a signal alarm is triggered, and the control unit 200 controls the intelligent controllable electrolytic power supply 300 to stop power supply in time, and the entire vehicle internal combustion engine energy-saving and emission reduction device 400 is turned off to stop generating gas; when the circulating liquid storage tank pressure sensor 402.14 fails or the control unit 200 fails, and the pressure cannot be protected and monitored, since a circulating liquid storage tank pressure relief cover 402.11 is provided on the top of the circulating liquid storage tank 402, when the gas pressure in the circulating liquid storage tank 402 reaches the alarm upper limit pressure value, the protective spring in the circulating liquid storage tank pressure relief cover 402.11 is compressed under the action of pressure, so that the pressure relief port is opened, and it automatically resets after the pressure is released.

[0095] Working principle of an automatic control system for an energy-saving device for an internal combustion engine of a vehicle:

[0096] The control unit first detects the vehicle start-stop state, and when the vehicle is powered on, performs parameter pre-detection on the vehicle and the hydrogen-oxygen-assisted fuel-saving and emission-reduction device for the vehicle internal combustion engine;

[0097] When the engine is in the starting state, the control unit enters the normal operation mode and judges the engine's operating conditions (idling, normal driving) based on the detection information of the vehicle's own sensors and external sensors;

[0098] When the vehicle starts to drive normally, the control unit collects, analyzes and calculates the data from each sensor in real time, and judges the vehicle's working condition, driving environment, road and traffic conditions in real time (the vehicle's working condition includes: the vehicle's starting, acceleration, constant speed, deceleration and other driving conditions; the driving environment includes: weather conditions, ambient temperature, air humidity, ambient wind force, atmospheric pressure, etc.; the road and traffic conditions include: flat, ramp or rugged road conditions, urban, suburban or highway roads, smooth or congested traffic, etc.);

[0099] At the same time, the control unit collects the voltage and current values ​​of the intelligent controllable electrolytic power supply in real time, and through the collection and analysis of the above parameters, according to the strategy set by the program, the calibrated current value under different conditions such as the vehicle's working condition, driving environment, road and traffic conditions is output. When the electrolysis current value changes, the gas production of the water electrolyzer also changes accordingly, thereby realizing the control of the air supply of the vehicle internal combustion engine fuel-saving and emission reduction device.

[0100] The control unit collects, analyzes and calculates the data of each sensor in the vehicle internal combustion engine fuel saving and emission reduction device in real time, judges the operation status of the device in real time, identifies various alarms and fault conditions, and promptly controls each actuator to perform corresponding processing actions to ensure the normal operation of the entire device and fault alarms.

[0101] Among them, the control unit can maintain real-time communication connection with the background data server through the network, and record the relevant information of the vehicle (such as vehicle speed, position, interval trajectory, etc.), various parameters in the vehicle internal combustion engine fuel-saving and emission reduction device (such as operation start and stop status, internal component execution action records, alarms and fault codes, etc.), device maintenance records and other data in real time, and push the items that need to be processed to sales and after-sales service network terminals in a timely manner.
