Description

Technical Field

[0001] The present invention relates to the field of engine technology, and in particular to an engine intake control system, a control method for an engine intake control system, a control device for an engine intake control system, an electronic device, and a computer-readable storage medium. Background Art

[0002] The opposed-piston two-stroke engine works by the opposite movement of the intake piston and the exhaust piston, which can increase the power frequency and effectively improve the engine's operating efficiency. The opposed-piston two-stroke engine omits the cylinder head and valve mechanism. Eliminating the cylinder head can reduce the volume of the cooling system, reduce heat dissipation to the cooling system, and improve the engine's thermal efficiency. Eliminating the valve mechanism can reduce friction loss and improve mechanical efficiency.

[0003] However, opposed-piston two-stroke engines complete the ventilation process by having the piston sweep across the intake and exhaust ports arranged at both ends of the cylinder liner. This shortens the intake and exhaust time, and the fuel-air mixing time as well, resulting in insufficient air intake in the cylinder and uneven mixing of fuel and air. By rationally increasing the size of the intake and exhaust ports and designing the intake port angle, the intake volume and intake tumble can be increased to a certain extent, thereby enhancing the mixing of air and fuel and improving combustion efficiency. However, related technologies often use a single intake port size and angle, which cannot flexibly adjust the intake volume and intake tumble according to changes in load conditions, thus reducing the user experience.

DETAILED DESCRIPTION

[0029] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0030] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the embodiments of the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0031] As shown in the background technology section, the opposed-piston two-stroke engine works by the opposite movement of the intake piston and the exhaust piston, which can increase the power frequency and effectively improve the engine's working efficiency. The opposed-piston two-stroke engine omits the cylinder head and the valve mechanism. The elimination of the cylinder head can reduce the volume of the cooling system, reduce heat dissipation to the cooling system, and improve the thermal efficiency of the engine. The elimination of the valve mechanism can reduce friction loss and improve mechanical efficiency.

[0032] In the process of implementing the present invention, the applicant discovered that the opposed-piston two-stroke engine completes the ventilation process by having the piston sweep the intake and exhaust ports arranged at both ends of the cylinder liner. This shortens the intake and exhaust time, and the fuel-air mixing time, resulting in insufficient air intake in the cylinder and uneven mixing of fuel and air. By reasonably increasing the size of the intake and exhaust ports and designing the intake port angle, the intake volume and intake tumble can be increased to a certain extent, thereby enhancing the mixing of air and fuel and improving combustion efficiency. However, in related technologies, a single intake port size and angle are mostly used, which cannot flexibly adjust the intake volume and intake tumble according to changes in load conditions, thereby reducing the user experience.

[0033] Therefore, the present invention can solve the problem that the engine cannot achieve flexible adjustment of the intake volume and tumble flow by using a single air intake size and angle. By installing controllable guide vanes at the air intake to change the flow rate and flow direction of the intake air, the intake flow rate and tumble flow can be flexibly adjusted. For different load conditions of the engine, the target intake volume and tumble flow can be obtained, the oil-gas mixing and combustion process are optimized, and the engine performance is improved.

The shape of the sub-air inlet 2 can be changed to a certain extent by driving the opening of the third guide vane 14, thereby changing the flow direction of the gas entering the cylinder 102, thereby changing the tumble flow.

[0044] The third guide vane assembly also includes a third vane position sensor 17, which can detect a third real-time opening of the third guide vane 14.

[0047] refer to Figure 5 , which is a flow chart of a control method of an engine intake control system according to some embodiments of the present invention.

[0048] like Figure 5 As shown, the control method of the engine intake control system according to the embodiment of the present invention may include the following steps: S501 , obtaining a speed signal from an engine speed sensor, an acceleration signal from an accelerator pedal position sensor of the engine, and a temperature signal from a cooling water temperature sensor of a cooling system of the engine.

[0050] S502: Determine the engine operating condition according to the speed signal, the acceleration signal, and the temperature signal.

[0051] Specifically, after obtaining the speed signal, acceleration signal and temperature signal, the engine operating condition is determined based on the speed signal, acceleration signal and temperature signal, wherein the engine operating condition can be idle condition, low load condition, medium load condition, high load condition, full load condition, medium and high load condition and acceleration condition, etc.

[0052] S503: Determine a first target opening, a second target opening, and a third target opening according to the operating condition of the engine.

[0053] Specifically, after determining the operating conditions of the engine, the first target opening, the second target opening and the third target opening are determined according to the operating conditions of the engine, wherein the first target opening corresponds to the optimal opening to which the first guide vane needs to be adjusted, the second target opening corresponds to the optimal opening to which the second guide vane needs to be adjusted, and the third target opening corresponds to the optimal opening to which the third guide vane needs to be adjusted.

[0054] S504, controlling the first guide vane drive motor according to the first target opening, so that the first guide vane drive motor drives the first guide vane adjustment ring to rotate with the axis of the engine cylinder to drive the first guide vane drive shaft to control the first real-time opening of the first guide vane, and thereby control the intake flow of the sub-intake port.

[0055] Specifically, after obtaining the first target opening, the first guide vane drive motor is controlled according to the first target opening, so that the first guide vane drive motor drives the first guide vane adjustment ring to rotate with the axis of the engine cylinder to drive the first guide vane drive shaft to control the first real-time opening of the first guide vane, and thus control the intake flow of the sub-intake port, that is, the first guide vane drive motor drives the first guide vane adjustment ring to rotate, the first guide vane adjustment ring drives the first guide vane drive shaft to rotate, and the first guide vane drive shaft drives the first guide vane to rotate. The change in the first real-time opening of the first guide vane can change the cross-sectional area of the sub-intake port, and thus change the intake flow of the sub-intake port.

[0056] S505, controlling the second guide vane drive motor according to the second target opening, so that the second guide vane drive motor drives the second guide vane adjustment ring to rotate with the axis of the engine cylinder to drive the second guide vane drive shaft to control the second real-time opening of the second guide vane, and thereby control the intake direction of the sub-intake port.

[0057] Specifically, after obtaining the second target opening, the second guide vane drive motor is controlled according to the second target opening, so that the second guide vane drive motor drives the second guide vane adjustment ring to rotate with the axis of the engine cylinder to drive the second guide vane drive shaft to control the second real-time opening of the second guide vane, and then control the intake direction of the sub-intake port, that is, the second guide vane drive motor drives the second guide vane adjustment ring to rotate, the second guide vane adjustment ring drives the second guide vane drive shaft to rotate, and the second guide vane drive shaft drives the second guide vane to rotate. The shape of the sub-intake port can be changed to a certain extent by driving the opening of the second guide vane, thereby changing the flow direction of the gas entering the cylinder, and then changing the tumble flow.

[0058] S506, controlling the third guide vane drive motor according to the third target opening, so that the third guide vane drive motor drives the third guide vane adjustment ring to rotate with the axis of the engine cylinder to drive the third guide vane drive shaft to control the third real-time opening of the third guide vane, and thereby control the intake direction of the sub-intake port.

[0059] Specifically, after obtaining the third target opening, the third guide vane drive motor is controlled based on the third target opening, so that the third guide vane drive motor drives the third guide vane adjustment ring to rotate about the axis of the engine cylinder, thereby driving the third guide vane drive shaft to control the third real-time opening of the third guide vane, thereby controlling the intake direction of the sub-inlet. Specifically, the third guide vane drive motor drives the third guide vane adjustment ring to rotate, which in turn drives the third guide vane drive shaft to rotate, and the third guide vane drive shaft drives the third guide vane to rotate. By driving the opening of the third guide vane, the shape of the sub-inlet can be changed to a certain extent, thereby changing the flow direction of gas entering the cylinder and, in turn, changing the tumble flow. This solves the problem of the inability to flexibly adjust the intake volume and tumble flow when using a single intake port size and angle in an engine. By installing controllable guide vanes in the intake port to change the flow rate and flow direction of the intake air, flexible adjustment of the intake volume and tumble flow can be achieved. Target intake volume and tumble flow can be achieved for different engine load conditions, optimizing the fuel-gas mixing and combustion process and improving engine performance.

[0060] In some embodiments of the present invention, before controlling the first guide vane drive motor according to the first target opening, controlling the second guide vane drive motor according to the second target opening, and controlling the third guide vane drive motor according to the third target opening, the method further includes: obtaining a first real-time opening of the first guide vane, a second real-time opening of the second guide vane, and a third real-time opening of the third guide vane; calculating a difference between the first real-time opening and the first target opening, a difference between the second real-time opening and the second target opening, and a difference between the third real-time opening and the third target opening; determining whether the difference between the first real-time opening and the first target opening is less than a first preset difference, and in response to the first real-time opening, determining whether the difference between the first real-time opening and the first target opening is less than a first preset difference, and If the difference between the second real-time opening and the first target opening is greater than a first preset difference, the first guide vane drive motor is controlled according to the first target opening. If the difference between the second real-time opening and the second target opening is less than a second preset difference, the second guide vane drive motor is controlled according to the second target opening. If the difference between the second real-time opening and the second target opening is greater than the second preset difference, the second guide vane drive motor is controlled according to the second target opening. If the difference between the third real-time opening and the third target opening is greater than the third preset difference, the third guide vane drive motor is controlled according to the third target opening. The first preset difference, the second preset difference, and the third preset difference can be calibrated according to actual conditions.

[0061] Specifically, before controlling the first guide vane drive motor according to the first target opening, controlling the second guide vane drive motor according to the second target opening, and controlling the third guide vane drive motor according to the third target opening, the first real-time opening of the first guide vane can be detected by the first blade position sensor, the second real-time opening of the second guide vane can be detected by the second blade position sensor, and the third real-time opening of the third guide vane can be detected by the third blade position sensor. Calculate the difference between the first real-time opening and the first target opening, calculate the difference between the second real-time opening and the second target opening, and calculate the difference between the third real-time opening and the third target opening, compare the difference between the first real-time opening and the first target opening with a first preset difference, and determine whether the difference between the first real-time opening and the first target opening is less than the first preset difference. When the difference between the first real-time opening and the first target opening is greater than the first preset difference, it can be indicated that the first real-time opening differs greatly from the first target opening, and the first real-time opening of the first guide vane needs to be adjusted. At this time, the first guide vane drive motor is controlled according to the first target opening so that the difference between the first real-time opening and the first target opening is not greater than the first preset difference. When the difference between the first real-time opening and the first target opening is not greater than the first preset difference, it can be indicated that the difference between the first real-time opening and the first target opening is not greater than the first preset difference, and the first real-time opening of the first guide vane does not need to be adjusted.

[0062] The difference between the second real-time opening and the second target opening is compared with the second preset difference to determine whether the difference between the second real-time opening and the second target opening is less than the second preset difference. When the difference between the second real-time opening and the second target opening is greater than the second preset difference, it can be said that the second real-time opening differs greatly from the second target opening, and the second real-time opening of the second guide vane needs to be adjusted. At this time, the second guide vane drive motor is controlled according to the second target opening so that the difference between the second real-time opening and the second target opening is not greater than the second preset difference. When the difference between the second real-time opening and the second target opening is not greater than the second preset difference, it can be said that the difference between the second real-time opening and the second target opening is not greater than the second preset difference, and the second real-time opening of the second guide vane does not need to be adjusted.

[0063] The difference between the third real-time opening and the third target opening is compared with the third preset difference to determine whether the difference between the third real-time opening and the third target opening is less than the third preset difference. When the difference between the third real-time opening and the third target opening is greater than the third preset difference, it can be said that the third real-time opening differs greatly from the third target opening, and the third real-time opening of the third guide vane needs to be adjusted. At this time, the operation of the third guide vane drive motor is controlled according to the third target opening so that the difference between the third real-time opening and the third target opening is not greater than the third preset difference. When the difference between the third real-time opening and the third target opening is not greater than the third preset difference, it can be said that the difference between the third real-time opening and the third target opening is not greater than the third preset difference, and the third real-time opening of the third guide vane does not need to be adjusted.

[0064] In some embodiments of the present invention, the operating conditions of the engine include: idle condition, low load condition, medium load condition and high load condition; the first target opening, the second target opening and the third target opening are determined according to the operating conditions of the engine, including: when the operating condition of the engine is idle condition, the first target opening, the second target opening and the third target opening are determined to be initial openings; wherein, the intake flow rate of the sub-intake port is the initial flow rate, the second guide vane under the second target opening and the third guide vane under the third target opening make the gas passing through the sub-intake port have a target tumble ratio; when the operating condition of the engine is low load condition, the first target opening is increased, and the second target opening and the third target opening are kept unchanged; wherein, the intake flow rate of the sub-intake port becomes the first intake flow rate, the first intake flow rate is greater than the initial flow rate, the second guide vane under the second target opening and the third guide vane under the third target opening make the gas passing through the sub-intake port have a target tumble ratio The gas passing through the sub-intake has a target tumble ratio; when the engine is operating at a medium load, the first target opening is continued to be increased, the second target opening is continued to be increased, and the third target opening is continued to be increased; wherein, the intake flow rate of the sub-intake becomes the second intake flow rate, the second intake flow rate is greater than the first intake flow rate, the second guide vane under the second target opening and the third guide vane under the third target opening make the gas passing through the sub-intake have a first tumble ratio, and the first tumble ratio is less than the target tumble ratio; when the engine is operating at a high load, the first target opening is continued to be increased, the second target opening and the third target opening are continued to be increased; wherein, the intake flow rate of the sub-intake becomes the third intake flow rate, the third intake flow rate is greater than the second intake flow rate, the second guide vane under the second target opening and the third guide vane under the third target opening make the gas passing through the sub-intake have a second tumble ratio, and the second tumble ratio is less than the first tumble ratio.

[0065] Specifically, the engine operating conditions include idle condition, low load condition, medium load condition and high load condition. Figure 6 , is a structural schematic diagram of an engine according to some embodiments of the present invention when the operating condition is an idle condition. When the operating condition of the engine is an idle condition, the first target opening, the second target opening and the third target opening are initial openings, that is, the target opening of each guide vane is the opening corresponding to the initial state. At this time, the intake flow rate of the sub-intake port is the initial flow rate, and the air can only enter the cylinder from the gap on both sides of the first guide vane. The openings of the second guide vane and the third guide vane make the gas passing through the sub-intake port have an optimal tumble ratio. Since the engine speed is low and the load is small, the intake volume is also relatively small. The stable intake volume helps to maintain the stability of the engine at idle condition.

[0066] refer to Figure 7, is a schematic diagram of the structure of an engine according to some embodiments of the present invention when operating at a low load. When the engine is operating at a low load, the opening of the first guide vane is increased, while the openings of the second and third guide vanes remain unchanged. The intake flow rate of the sub-intake port becomes the first intake flow rate, which is greater than the initial flow rate. The second guide vane at the second target opening and the third guide vane at the third target opening ensure that the gas passing through the sub-intake port has an optimal tumble ratio, thereby increasing the intake volume to meet the engine's power output requirements. The intake tumble flow under the low load condition is the same as the intake tumble flow under the idle condition. When the engine is operating at a low load and idle condition, the tumble flow should be appropriately increased to facilitate mixing of air and fuel, promote combustion efficiency, and improve combustion stability at low speeds.

[0067] refer to Figure 8 , is a structural schematic diagram of an engine according to some embodiments of the present invention when the operating condition is a medium load condition. When the engine is operating at a medium load condition, the engine needs to output moderate power while maintaining good fuel economy. The intake volume needs to be controlled within a moderate range. At this time, the opening of the first guide vane continues to increase, and the openings of the second guide vane and the third guide vane also increase. At this time, the intake volume continues to increase, and the intake flow rate of the sub-intake port becomes a second intake flow rate, which is greater than the first intake flow rate. The second guide vane at the second target opening and the third guide vane at the third target opening make the gas passing through the sub-intake port have a first tumble ratio, which is less than the target tumble ratio, that is, the tumble ratio under the medium load condition is smaller than the tumble ratio under the idle condition.

[0068] refer to Figure 9 , is a schematic structural diagram of an engine according to some embodiments of the present invention when operating at a high load condition. When the engine is operating at a high load condition, in order to meet the maximum power output requirement of the engine, the intake volume needs to be significantly increased. At this time, the opening of the first guide vane is further increased until the opening of the first guide vane is fully open. The openings of the second guide vane and the third guide vane are further increased until the openings of the second guide vane and the third guide vane are the same as the openings of the second guide vane and the third guide vane under a medium load condition. At this time, the intake volume is maximum, and the intake flow rate of the sub-intake port becomes a third intake flow rate, which is greater than the second intake flow rate. The second guide vane at the second target opening and the third guide vane at the third target opening cause the gas passing through the sub-intake port to have a second tumble ratio, which is less than the first tumble ratio. The intake tumble ratio under the high load condition is less than the intake tumble ratio under the medium load condition.

[0069] refer to Figure 10, is a schematic diagram of the structure of an engine according to some embodiments of the present invention operating under acceleration conditions. When the engine is operating under acceleration conditions, the engine needs to meet the demand for rapid power output in a short period of time. The intake volume should be increased rapidly to meet the engine's acceleration requirements. At the same time, reducing tumble flow can effectively reduce intake resistance and improve charging efficiency. At this time, the openings of the first, second, and third guide vanes are all fully open, that is, the openings of the second and third guide vanes are further increased. At this time, the intake volume is maximized and the tumble flow is minimized. When the engine is operating under medium-to-high load conditions, excessive tumble flow will increase intake flow resistance, thereby reducing charging efficiency. Reasonable tumble flow can balance intake volume and turbulence intensity, ensuring more complete and efficient combustion.

[0070] refer to Figure 11 , is a schematic diagram of a control framework of an engine intake control system according to some embodiments of the present invention.

[0071] The control framework of the engine's intake control system may include a first guide vane drive shaft 9, a second guide vane drive shaft 10, a third guide vane drive shaft 11, a first vane position sensor 15, a second vane position sensor 16, a third vane position sensor 17, a speed sensor 18, an accelerator pedal position sensor 19, a cooling water temperature sensor 20, an operator 21, a controller 22, a first actuator 23, a second actuator 24 and a third actuator 25.

[0072] The operator 21 can receive the first real-time opening of the first guide vane 12, the second real-time opening of the second guide vane 13, and the third real-time opening of the third guide vane 14 detected by the first blade position sensor 15, the second blade position sensor 16, and the third blade position sensor 17. The operator 21 can also receive the speed signal, acceleration signal, and temperature signal detected by the speed sensor 18, the accelerator pedal position sensor 19, and the cooling water temperature sensor 20. The operator 21 can determine the operating condition of the engine based on the speed signal, acceleration signal, and temperature signal and output the optimal opening of each guide vane corresponding to the current operating condition. The arithmetic unit 21 sends the optimal opening of each guide vane corresponding to the current operating condition to the controller 22. Controller 22 receives the signal from the arithmetic unit 21 and sends the control signal to the first, second, and third actuators 23, 24, and 25, causing the controller 22 to control the first, second, and third actuators 23, 24, and 25. After receiving the control signal from the controller 22, the first, second, and third actuators 23, 24, and 25 execute the control strategy for the optimal opening of the different guide vanes. The first actuator 23 outputs a signal to control the first guide vane drive shaft 9, thereby controlling the first real-time opening of the first guide vane 12. The second actuator 24 outputs a signal to control the second guide vane drive shaft 10, thereby controlling the second real-time opening of the second guide vane 13. The third actuator 25 outputs a signal to control the third guide vane drive shaft 11, thereby controlling the third real-time opening of the third guide vane 14.

[0073] As a specific example, Figure 12 As shown, the control method of the engine intake control system of the present invention may include the following steps: S1201, the engine starts running.

[0074] S1202, determining whether the guide vane drive motor can operate normally after being powered on. If yes, proceed to step S1203; if not, proceed to step S1209.

[0075] S1203, obtaining a speed signal from an engine speed sensor, an acceleration signal from an accelerator pedal position sensor of the engine, and a temperature signal from a cooling water temperature sensor of a cooling system of the engine.

[0076] S1204: Determine the current operating condition of the engine based on the speed signal, the acceleration signal, and the temperature signal, and output the optimal opening of the guide vanes corresponding to the current operating condition.

[0077] S1205 , the first blade position sensor detects a first real-time opening of the first guide vane, the second blade position sensor detects a second real-time opening of the second guide vane, and the third blade position sensor detects a third real-time opening of the third guide vane.

[0078] S1206: Determine whether the difference between the real-time opening of each guide vane and the target opening is less than a first preset difference. If yes, end the step; if not, proceed to step S1207.

[0079] S1207: Convert the difference between the real-time opening of each guide vane and the target opening into a guide vane drive motor control signal.

[0080] S1208, the guide vane driving motor drives the guide vane adjusting ring according to the guide vane driving motor control signal, thereby adjusting the opening of each guide vane, and then continuing to execute step S1206.

[0081] S1209: The guide vane drive motor sends a fault alarm signal.

[0082] Therefore, by controlling the opening size of different guide vanes, flexible adjustment of the intake flow and intake tumble under different working conditions can be achieved. Aiming at the actual operation process of the engine, a complete intake structure control method is proposed. Based on the difference between the actual opening of the guide vane and the target opening, each guide vane is controlled in a closed loop to achieve precise control of the opening of each guide vane, thereby achieving precise control of the intake volume and tumble.

[0083] In summary, the control method of the intake control system of an engine according to an embodiment of the present invention includes: obtaining a speed signal from a speed sensor of the engine, an acceleration signal from an accelerator pedal position sensor of the engine, and a temperature signal from a cooling water temperature sensor of a cooling system of the engine; determining an operating condition of the engine according to the speed signal, the acceleration signal, and the temperature signal; determining a first target opening, a second target opening, and a third target opening according to the operating condition of the engine; controlling a first guide vane drive motor according to the first target opening, so that the first guide vane drive motor drives a first guide vane adjustment ring to rotate about the axis of a cylinder of the engine, so as to drive the first guide vane drive shaft, so as to control the first guide vane The invention relates to a method for controlling a first real-time opening of a guide vane to control the intake flow rate of the sub-intake port; controlling a second guide vane drive motor according to a second target opening, so that the second guide vane drive motor drives the second guide vane adjustment ring to rotate about the axis of the engine cylinder to drive the second guide vane drive shaft to control the second real-time opening of the second guide vane, thereby controlling the intake direction of the sub-intake port; and controlling a third guide vane drive motor according to a third target opening, so that the third guide vane drive motor drives the third guide vane adjustment ring to rotate about the axis of the engine cylinder to drive the third guide vane drive shaft to control the third real-time opening of the third guide vane, thereby controlling the intake direction of the sub-intake port. Thus, the method can solve the problem that the intake volume and tumble flow cannot be flexibly adjusted when the engine adopts a single intake port size and angle. By installing controllable guide vanes in the intake port to change the flow rate and flow direction of the intake air, the intake volume and tumble flow can be flexibly adjusted. Target intake volume and tumble flow can be obtained for different engine load conditions, optimizing the fuel-gas mixing and combustion process, and improving engine performance.

[0084] It should be noted that the method of the embodiment of the present invention can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied in a distributed scenario, where multiple devices cooperate to perform the method. In such a distributed scenario, one of the multiple devices may only perform one or more steps of the method of the embodiment of the present invention, and the multiple devices will interact with each other to complete the above method.
