Description

Technical Field

[0001] This invention relates to the field of engine intake system technology, and in particular to an intake manifold pressure regulating chamber condensate distribution and guiding device, method, engine, and vehicle. Background Technology

[0002] The engine's EGR (Exhaust Gas Recirculation) system redirects a portion of the combusted exhaust gases back into the intake manifold, where they mix with fresh air and are then re-entered for combustion in the cylinders. This process achieves two main objectives: ① reducing the combustion temperature within the cylinders and decreasing nitrogen oxide (NOx) levels. x ① Emissions; ② In some operating conditions, it can slightly reduce fuel consumption and suppress knocking.

[0003] However, since the exhaust gas after combustion contains a large amount of water vapor, the high-temperature exhaust gas will produce a large amount of condensate after passing through the EGR cooler. If the amount of condensate entering each cylinder is uneven, it will cause misfires in some cylinders. In summary, the existing technology cannot achieve real-time monitoring of condensate in each cylinder, automatic adjustment of the guide angle, and adaptive distribution under multiple operating conditions, which can easily lead to uneven distribution, engine misfires, vibration, accelerated wear, and deterioration of emissions. Summary of the Invention

The actuator body drives the rotating shaft to rotate, which in turn drives the flow guide baffle to reciprocate on the flow guide groove through the transmission device. The rotating shaft is parallel to the plane where the outlet is located.

[0020] Furthermore, the number of the flow guiding components is the same as the number of outlets.

[0021] Furthermore, the transmission device is a lead screw assembly or a chain assembly.

[0025] S3: Obtain the second water volume signal at the outlet of the pressure stabilizing chamber;

[0026] S4: Repeat steps S1 to S3. When the second water volume signal meets the preset conditions, the controller stops control.

[0027] Furthermore, the flow guiding component guides the gas-liquid mixture into the outlet of the pressure stabilizing chamber by rotating or moving it.

[0028] Furthermore, when there are multiple actuators, the controller controls each actuator individually.

[0046] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please refer to Figure 1 and Figure 2 In one embodiment of the present invention, the intake manifold pressure regulating chamber condensate distribution and guiding device includes:

[0048] Voltage stabilizing chamber 1;

[0049] The flow guiding component 2 is disposed inside the pressure stabilizing chamber 1;

[0050] A water volume sensor 3 is installed at the outlet 11 of the pressure stabilizing chamber, and the water volume sensor 3 measures the water volume at the outlet 11;

[0051] Actuating device 4 is connected to the flow guiding component 2, and the actuating device 4 controls the flow guiding component 2 to guide the flow;

[0052] The controller (not shown in the figure) is connected to the water volume sensor 3 and the actuator 4. The controller controls the actuator 4 according to the water volume signal of the water volume sensor 3, and then controls the flow guiding component 2 to guide the flow.

[0053] In this embodiment, the actuator is electrically driven, but this is not a limitation. Those skilled in the art can use any known method for driving, such as electric, hydraulic, pneumatic, electromagnetic, or servo motors, depending on the specific circumstances. Furthermore, when different driving methods are used, the actuator of this invention will include corresponding accessories. For example, when the driving method is hydraulic, this invention will include oil circuits, electrical circuits, etc., corresponding to the hydraulic drive system; or when the driving method is pneumatic, this invention will include air circuits, etc., corresponding to the start-up drive system. All of the above fall within the scope of protection claimed by this invention.

[0054] Furthermore, in this embodiment, the water volume sensor is a liquid level sensor, and the data it detects is also liquid level data; however, this is not a limitation. Those skilled in the art can use any known sensor to detect the liquid volume at the outlet, depending on the actual situation. For example, flow rate, humidity, image recognition, etc. Simultaneously, when different sensors are used to detect different data, the water volume sensor of this invention will include corresponding accessories. For example, when the water volume sensor uses image recognition to detect water volume, this invention will include accessories corresponding to image recognition, such as an image acquisition device, an image analysis device, etc. When the water volume sensor uses flow rate recognition to detect water volume, this invention will include accessories corresponding to flow rate recognition, such as a flow meter, etc. When the water volume sensor uses humidity to detect water volume, this invention will include accessories corresponding to humidity, such as a hygrometer, etc. All of the above fall within the scope of protection claimed by this invention.

[0055] Furthermore, while the controller described in this application is an independent MCU, it is not a limitation. Those skilled in the art can change the type of controller according to actual needs, such as integrating an ECU, all of which fall within the scope of protection claimed by this invention.

[0056] In one embodiment of the present invention, the execution device 4 includes:

[0057] The actuator body 41 is disposed outside the voltage stabilizing chamber 1;

[0058] A rotating shaft 42 is inserted through the housing 12 of the pressure stabilizing chamber 1. One end of the rotating shaft 42 located outside the housing 12 is connected to the actuator body 41, and the other end of the rotating shaft 42 located inside the housing 12 is connected to the flow guiding assembly 2. The actuator body 41 drives the rotating shaft 42 to rotate, thereby driving the flow guiding assembly 2 to rotate. The rotating shaft 42 is perpendicular to the plane where the outlet 11 is located.

[0059] The flow guiding structure is installed inside the pressure stabilizing chamber via a rotating shaft, which extends out of the housing and is fixedly connected to the output end of the external actuator. A water volume sensor is installed in the intake branch corresponding to each cylinder. The water volume sensor signal is connected to the controller, and the controller output is connected to the actuator to form a closed-loop control circuit.

[0060] When the engine is running, the water level sensors of each cylinder collect the condensate flow / level signal of the intake branch in real time and upload it to the controller. The controller combines the engine speed, load, water temperature, EGR rate and other operating conditions to determine the condensate distribution status. When the distribution is uneven or the operating conditions change, the controller drives the actuator to deflect the guide structure to adjust the angle, thereby changing the condensate flow direction and distribution ratio in real time to achieve adaptive optimal distribution under multiple operating conditions.

[0061] In this embodiment, the flow guiding component 2 includes only the first flow baffle 21. However, in other embodiments of the invention, the flow guiding component 2 also includes a second flow guiding baffle 22.

[0062] The second flow guide baffle 22 extends from the inlet of the pressure stabilizing chamber all the way to the innermost part of the chamber. The end closer to the inlet is higher than the end furthest from the inlet. Its function is to guide the flow deeper while preventing excessive condensate from flowing into the outlet 11 near the inlet.

[0063] In one embodiment of the present invention, the flow guiding component includes:

[0064] A flow guide rail is disposed inside the pressure stabilizing chamber;

[0065] A flow guide baffle is movably mounted on the flow guide slide rail;

[0066] The conduction device is connected to the flow guide baffle;

[0067] The actuator includes:

[0068] The actuator body is located outside the voltage stabilizing chamber;

[0069] A rotating shaft is installed on the housing of the pressure stabilizing chamber. One end of the rotating shaft located on the outside of the housing is connected to the actuator body, and the other end of the rotating shaft located on the inside of the housing is connected to the transmission device. The actuator body drives the rotating shaft to rotate, which in turn drives the flow guide baffle to reciprocate on the flow guide groove through the transmission device. The rotating shaft is parallel to the plane where the outlet is located.

[0070] In this invention, the number of flow guiding components can be the same as or different from the number of outlets. When the number of flow guiding components is the same as the number of outlets, one flow guiding component corresponds to one outlet. When the number of flow guiding components is different from the number of outlets, one flow guiding component corresponds to multiple outlets, or multiple flow guiding components correspond to one outlet. Under certain extreme ideal conditions, the water volume of all outlets can be adjusted by controlling one flow guiding component. Whether the number is the same or different, there is no difference in the technical solution and usage method. When the numbers are the same, the angle or position of each flow guiding component is controlled to achieve the purpose of controlling the water volume of its corresponding outlet. This invention has been described in the above embodiments; in different cases, an extreme example is when there is only one flow guiding component corresponding to four outlets, the water volume of all outlets is also adjusted by controlling the angle or position of this one flow guiding component. Because the pressure stabilizing chamber is relatively sealed, adjusting the angle or position of the flow guiding component located inside it can achieve the purpose of changing the water volume of all outlets, regardless of the number of these flow guiding components.

[0071] In this embodiment, the transmission device is a lead screw assembly. However, this is not a limitation. Those skilled in the art can use any consistent method according to actual needs, as long as it can convert the rotation of the shaft into the movement of the guide baffle, all of which fall within the scope of protection claimed by this invention. For example, a chain assembly, etc. However, when different methods are used, the technical solutions included in this invention are also different. For example, when a lead screw assembly is used, this invention includes the components corresponding to the lead screw assembly. When a chain assembly is used, this invention includes the components corresponding to the chain assembly, such as gears, etc.

[0072] The present invention also provides a method for distributing and guiding condensate in the intake manifold pressure regulating chamber, comprising:

[0073] S1: The water flow sensor acquires the first water flow signal at the outlet of the pressure regulating chamber;

[0074] S2: The controller controls the actuator according to the water volume signal and preset conditions, and then controls the flow guiding component to guide the gas-liquid mixture that enters from the pressure stabilizing chamber inlet to the pressure stabilizing chamber outlet;

[0075] S3: Obtain the second water volume signal at the outlet of the pressure stabilizing chamber;

[0076] S4: Repeat steps S1 to S3. When the second water volume signal meets the preset conditions, the controller stops control.

[0077] In this embodiment, the actuator is electrically driven, but this is not a limitation. Those skilled in the art can use any known method for driving, such as electric, hydraulic, pneumatic, electromagnetic, or servo motors, depending on the specific circumstances. Furthermore, when different driving methods are used, the actuator of this invention will include corresponding accessories. For example, when the driving method is hydraulic, this invention will include oil circuits, electrical circuits, etc., corresponding to the hydraulic drive system; or when the driving method is pneumatic, this invention will include air circuits, etc., corresponding to the start-up drive system. All of the above fall within the scope of protection claimed by this invention.

[0078] Furthermore, in this embodiment, the water volume sensor is a liquid level sensor, and the data it detects is also liquid level data; however, it is not limited to this. Those skilled in the art can use any known sensor to detect the volume of liquid exiting the outlet, depending on the actual situation. For example, flow rate, humidity, image recognition, etc. Simultaneously, when different sensors are used to detect different data, the water volume sensor of this invention will include corresponding accessories. For example, when the water volume sensor uses image recognition to detect water volume, this invention will include accessories corresponding to image recognition, such as an image acquisition device, an image analysis device, etc. When the water volume sensor uses flow rate recognition to detect water volume, this invention will include accessories corresponding to flow rate recognition, such as a flow meter, etc. When the water volume sensor uses humidity to detect water volume, this invention will include accessories corresponding to humidity, such as a hygrometer, etc. All of the above fall within the scope of protection claimed by this invention.
