Background Technology

[0002] Cooling nozzles are part of the engine's cooling system, and are generally found on engines with high heat loads. They are usually fixedly mounted on the engine's oil passages. During engine operation, the cooling nozzles spray cooling oil onto the piston. The cooler oil carries away the piston's heat through heat exchange, thus cooling the piston.

[0003] Existing piston cooling nozzle control is only related to oil pressure and cannot infinitely control the amount of oil injected through the piston cooling nozzle, resulting in a poor user experience. Summary of the Invention

[0004] To address the aforementioned technical problems, embodiments of this application provide a method for controlling the amount of oil injected through a piston cooling nozzle, a device for controlling the amount of oil injected through a piston cooling nozzle, an electronic device, and a computer-readable storage medium, which can infinitely control the amount of oil injected through the piston cooling nozzle.

[0005] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0006] According to one aspect of the present application, a method for controlling the injection quantity of a piston cooling nozzle is provided, comprising: receiving target pressure data for the piston cooling nozzle and acquiring current pressure data of the piston cooling nozzle; obtaining a target duty cycle based on the target pressure data and the current pressure data; and controlling the injection quantity of the piston cooling nozzle based on the target duty cycle.

[0007] In an exemplary embodiment, controlling the amount of fuel injected through the piston cooling nozzle based on the target duty cycle includes: generating a PWM signal based on the target duty cycle; and controlling the opening of a proportional solenoid valve based on the PWM signal, wherein the proportional solenoid valve is used to control the amount of fuel injected through the piston cooling nozzle.

[0008] In an exemplary embodiment, before controlling the opening of the proportional solenoid valve based on the PWM signal, the method further includes: amplifying the PWM signal; and sending the amplified PWM signal to the proportional solenoid valve.

[0009] In one exemplary embodiment, acquiring the current pressure data of the piston cooling nozzle includes detecting the current pressure data using a pressure sensor disposed at the piston cooling nozzle.

[0010] In an exemplary embodiment, the method further includes: detecting oil temperature data at the piston cooling nozzle; and sending the oil temperature data and the current pressure data to a host computer so that the host computer displays the oil temperature data and the current pressure data.

[0011] In an exemplary embodiment, the method further includes: determining the current fuel injection quantity flowing through the piston cooling nozzle based on the oil temperature data and the oil pressure data; and sending the current fuel injection quantity to a host computer so that the host computer displays the current fuel injection quantity.

[0012] In an exemplary embodiment, determining the current injection quantity of the piston cooling nozzle based on the oil temperature data and the oil pressure data includes: matching the oil temperature data and the current pressure data with a pre-built injection quantity data table to determine the oil flow rate, wherein the injection quantity data table includes multiple sets of oil temperature data, pressure data, and corresponding injection quantity data.

[0013] According to one aspect of the present application, a fuel injection quantity control device for a piston cooling nozzle is provided, comprising: a receiving and acquisition module for receiving target pressure data for the piston cooling nozzle and acquiring current pressure data of the piston cooling nozzle; a calculation module for obtaining a target duty cycle based on the target pressure data and the current pressure data; and a control module for controlling the fuel injection quantity flowing through the piston cooling nozzle based on the target duty cycle.

[0014] According to one aspect of the embodiments of this application, an electronic device is provided, including a processor and a memory, wherein computer-readable instructions are stored in the memory, and when the computer-readable instructions are executed by the processor, the above-described method for controlling the amount of oil injected into a piston cooling nozzle is implemented.

[0015] According to one aspect of the embodiments of this application, a computer-readable storage medium is provided, on which computer-readable instructions are stored, which, when executed by a computer processor, cause the computer to perform the previously provided method for controlling the amount of oil injected into a piston cooling nozzle.

[0016] According to one aspect of the embodiments of this application, a computer program product or computer program is provided, which includes computer instructions stored in a computer-readable storage medium. A processor of a computer device reads the computer instructions from the computer-readable storage medium and executes the computer instructions, causing the computer device to perform the oil injection quantity control method for the piston cooling nozzle provided in the various alternative embodiments described above.

[0017] The technical solution provided in the embodiments of this application considers that the greater the amount of oil injected through the piston cooling nozzle per unit time, the greater the pressure at the piston cooling nozzle. Therefore, by controlling the amount of oil injected through the piston cooling nozzle through the target duty cycle determined by the target pressure data and the current pressure data, the amount of oil injected through the piston cooling nozzle can be infinitely controlled. This solves the problem that the current piston cooling nozzle control system can only control the opening and closing of the cooling nozzle according to the engine operating conditions (such as speed, load, etc.) and cannot infinitely adjust the inlet pressure of the cooling nozzle.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0032] It should also be noted that "multiple" as mentioned in this application refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0033] Through long-term research, the inventors of this application have discovered that the current piston cooling nozzle control system is integrated into the vehicle ECU (Electronic Control Unit). It can only control the switching of the cooling nozzle according to the engine operating conditions (such as speed, load, etc.), and cannot infinitely adjust the inlet pressure of the cooling nozzle, nor can it collect the oil temperature at the inlet of the cooling nozzle.

[0034] To address at least the aforementioned problems in the prior art, embodiments of this application propose a method for controlling the amount of fuel injected into a piston cooling nozzle, a device for controlling the amount of fuel injected into a piston cooling nozzle, an electronic device, and a computer-readable storage medium. These embodiments will be described in detail below.

[0035] Please see Figure 1 , Figure 1 This is a flowchart illustrating an exemplary embodiment of the fuel injection quantity control method for a piston cooling nozzle, as shown in the following example. Figure 1 As shown, the piston cooling nozzle oil injection quantity control method provided in this embodiment includes steps S101 to S103, which are described in detail below:

[0036] Step S101: Receive target pressure data for the piston cooling nozzle and acquire current pressure data for the piston cooling nozzle.

[0037] In this embodiment, the current pressure data of the piston cooling nozzle is the current pressure of the engine oil flowing through the piston cooling nozzle.

[0038] In this embodiment, a target pressure data for the oil flowing through the piston cooling nozzle is preset, and the target pressure data is sent from the host computer to the slave computer. For example, the target pressure data for the piston cooling nozzle is preset based on empirical data. For instance, the empirical data may include multiple injection quantities within a preset time period and the ideal pressure data corresponding to each injection quantity. Data fitting is performed on the empirical data to determine the fitting curve of the ideal pressure data for the injection quantity. The ideal pressure data corresponding to each injection quantity is the oil injection quantity of the piston cooling nozzle that achieves the ideal cooling effect under the corresponding pressure data. In practical applications, the target injection quantity for the piston cooling nozzle is predetermined, and then the target pressure data corresponding to the target injection quantity is determined based on the fitting curve.

[0039] The current pressure data of the piston cooling nozzle is related to the current fuel injection quantity of the piston cooling nozzle. That is, if the current fuel injection quantity of the piston cooling nozzle is larger, the current pressure data of the piston cooling nozzle will be larger, and vice versa.

[0040] For example, current pressure data is detected by a pressure sensor located at the piston cooling nozzle.

[0041] Step S102: Obtain the target duty cycle based on the target pressure data and the current pressure data.

[0042] For example, PID calculations are performed on the target pressure data and the current pressure data to obtain the target duty cycle.

[0043] This embodiment uses a PID (Proportion-Integral-Differential Coefficient) control algorithm to perform closed-loop control of the pressure at the piston cooling nozzle.

[0044] Closed-loop control is a control method that corrects for deviations based on the output feedback of the controlled object. It corrects deviations according to quotas or standards when a discrepancy is detected between the actual and planned output. For example, controlling the speed of a motor requires a speed sensor, and the result is fed back to the control path. When discussing closed-loop control algorithms, the PID control algorithm is essential. PID stands for Proportional, Integral, and Differential, representing three control algorithms. Combining these three algorithms can effectively correct deviations in the controlled object, thereby achieving a stable state. The PID control algorithm integrates proportional, integral, and derivative components, and it is the most mature and widely used control algorithm in continuous systems. This algorithm is suitable for situations where the model of the controlled object is unclear. Essentially, PID control calculates the input deviation value according to the proportional, integral, and derivative functional relationships, and the result is used to control the output.

[0045] For example, in this embodiment, the target duty cycle can be obtained by performing PID calculation on the target pressure data and the current pressure data using the following formula:

[0046]

[0047] Among them, K p For proportional gain, K p It is inversely proportional to the scale; T t T is the integration time constant; D is the differential time constant; u(t) is the output signal of the PID controller, i.e., the target duty cycle; e(t) is the difference between the target pressure data and the current pressure data.

[0048] It is understood that this embodiment can also use PI control method, PD control method and ID control method to perform PID calculation on target pressure data and current pressure data according to actual application scenarios to obtain target duty cycle.

[0049] Step S103: Control the amount of oil injected through the piston cooling nozzle based on the target duty cycle.

[0050] In this embodiment, considering that the greater the amount of fuel injected through the piston cooling nozzle per unit time, the greater the pressure at the piston cooling nozzle, the amount of fuel injected through the piston cooling nozzle is controlled by the target duty cycle determined by the target pressure data and the current pressure data. This enables stepless control of the amount of fuel injected through the piston cooling nozzle, solving the problem that the current piston cooling nozzle control system can only control the opening and closing of the cooling nozzle according to the engine operating conditions (such as speed, load, etc.) and cannot steplessly adjust the inlet pressure of the cooling nozzle.

[0051] See Figure 2 , Figure 2 yes Figure 1 Step S103 in the illustrated embodiment is shown in a flowchart of an exemplary embodiment, as follows: Figure 2 As shown, step S103 includes steps S201-S202, which are described in detail below:

[0052] Step S201: Generate a PWM signal based on the target duty cycle.

[0053] This embodiment combines pulse width modulation and target duty cycle to control the amount of oil injected through the piston cooling nozzle.

[0054] Pulse width modulation (PWM) is an analog control method that modulates the bias of the base of a transistor or the gate of a MOSFET according to changes in the load, thereby altering the conduction time of the transistor or MOSFET and thus changing the output of a switching power supply. This method allows the power supply's output voltage to remain constant under varying operating conditions and is a highly effective technique for controlling analog circuits using digital signals from a microprocessor. It is widely used in many fields, from measurement and communication to power control and conversion.

[0055] In this embodiment, the target duty cycle is used as the duty cycle of the generated PWM signal.

[0056] Step S202: Control the opening degree of the proportional solenoid valve based on the PWM signal.

[0057] In this embodiment, a proportional solenoid valve is provided to control the amount of oil injected through the piston cooling nozzle. A proportional control valve is a hydraulic control valve that makes the parameters of the output oil, such as pressure, flow rate, and direction, proportional to changes in the input electrical signal parameters, thereby achieving continuous proportional control. The proportional solenoid valve is a new type of hydraulic control element that integrates the advantages of on / off electro-hydraulic control elements and servo electro-hydraulic control elements. This proportional solenoid valve can be used for open-loop control or, with the addition of a feedback loop, to form closed-loop control, exhibiting good static performance and dynamic performance that meets general industrial control requirements.

[0058] Since the distance between the target pressure data and the current pressure data is related to the pulse width of the PWM signal, and the pulse width of the PWM signal is related to the opening degree of the proportional solenoid valve, in this embodiment, the opening degree of the proportional solenoid valve is determined by the pulse width of the PWM signal, so that the amount of oil injected through the piston cooling nozzle is positively correlated with the target pressure data.

[0059] For example, see Figure 3 , Figure 3 Is Figure 2 A flowchart of an exemplary embodiment of the piston cooling nozzle oil injection quantity control method proposed based on the illustrated embodiment is shown below. Figure 3 As shown, before step S202, the piston cooling nozzle oil injection quantity control method provided in this embodiment further includes steps S301 to S302, which are described in detail below:

[0060] Step S301: Amplify the power of the PWM signal.

[0061] For example, the PWM signal is input to a MOSFET power amplifier to amplify the power of the PWM signal. For example, the power amplification of the PWM signal is adapted to the operating voltage of the proportional solenoid valve.

[0062] Step S302: Send the amplified PWM signal to the proportional solenoid valve.

[0063] In this embodiment, a power-amplified PWM signal is sent to a proportional solenoid valve to control the opening degree of the proportional solenoid valve using the power-amplified PWM signal.

[0064] For example, see Figure 4 , Figure 4 Is Figure 1 A flowchart of an exemplary embodiment of the piston cooling nozzle oil injection quantity control method proposed based on the illustrated embodiment is shown below. Figure 4 As shown, the piston cooling nozzle oil injection quantity control method provided in this embodiment further includes steps S401 to S402, which are described in detail below:

[0065] Step S401: Detect the oil temperature data at the piston cooling nozzle.

[0066] Considering that oil temperature affects oil viscosity, it also affects the flow rate and velocity of the oil passing through the piston cooling nozzle. Therefore, this embodiment detects the oil temperature data at the piston cooling nozzle and combines it with oil pressure data to determine the flow rate and velocity of the oil passing through the piston cooling nozzle.

[0067] For example, the oil temperature at the piston cooling nozzle is detected using a type K thermocouple. A type K thermocouple is a temperature sensor typically used in conjunction with display instruments, recording instruments, and electronic controllers. A type K thermocouple generally consists of a sensing element, mounting hardware, and a junction box. Type K thermocouples offer advantages such as good linearity, high thermoelectric potential, high sensitivity, good stability and uniformity, strong oxidation resistance, and low cost.

[0068] Step S402: Send the oil temperature data and current pressure data to the host computer so that the host computer can display the oil temperature data and current pressure data.

[0069] In this embodiment, the oil temperature data and current pressure data are sent to a host computer so that the host computer can display these data, thus clearly presenting them to the user and improving the user experience. Additionally, the user can refer to the oil temperature and current pressure data to determine the target pressure data. For example, if the current pressure and oil temperature data are high, the target pressure data is determined to be low to reduce the oil pressure and temperature. Conversely, if the current pressure and oil temperature data are low, the target pressure data is determined to be high to increase the oil pressure and temperature.

[0070] For example, see Figure 5 , Figure 5 Is Figure 4 A flowchart of an exemplary embodiment of the piston cooling nozzle oil injection quantity control method proposed based on the illustrated embodiment is shown below. Figure 5 As shown, the piston cooling nozzle oil injection quantity control method provided in this embodiment further includes steps S501 to S502, which are described in detail below:

[0071] Step S501: Determine the current amount of oil injected through the piston cooling nozzle based on the oil temperature data and oil pressure data.

[0072] For example, empirical data is subjected to data fitting processing to determine the correspondence curve between oil temperature data, oil pressure data, and the current fuel injection quantity flowing through the piston cooling nozzle. In this embodiment, the above-mentioned correspondence curve is a bivariate curve, that is, the current fuel injection quantity flowing through the piston cooling nozzle is related to two dimensions: oil temperature data and oil pressure data.

[0073] In practical applications, the current amount of oil injected through the piston cooling nozzle can be obtained by substituting the oil temperature data and oil pressure data into the corresponding curve mentioned above.

[0074] For example, the oil temperature data and current pressure data are matched with a pre-built fuel injection quantity data table to determine the oil flow rate. The fuel injection quantity data table includes multiple sets of oil temperature data, pressure data, and corresponding fuel injection quantities. In this embodiment, a pre-built fuel injection quantity data table is constructed, including multiple sets of oil temperature data, pressure data, and corresponding fuel injection quantities. For example, the fuel injection quantity under each oil temperature and pressure data is determined based on experimental data. For example, to more accurately determine the fuel injection quantity under each oil temperature and pressure data, multiple experiments are performed for each set of oil temperature and pressure data, and the average of the multiple fuel injection quantities corresponding to the multiple experiments is taken as the final fuel injection quantity.

[0075] Step S502: Send the current fuel injection quantity to the host computer so that the host computer can display the current fuel injection quantity.

[0076] This embodiment sends the current fuel injection quantity to the host computer, so that the host computer can display the current fuel injection quantity to the user. This allows the user to clearly understand the current fuel injection quantity, which in turn facilitates the user to determine target pressure data and perform other operations based on the current fuel injection quantity.

[0077] For example, see Figure 6 , Figure 6 This is a block diagram illustrating an exemplary embodiment of a piston cooling nozzle fuel injection quantity control system, as shown below. Figure 6 As shown, the piston cooling nozzle oil injection quantity control system provided in this embodiment includes a host computer and a slave computer, wherein the slave computer is used to perform the following steps:

[0078] Receive target hydraulic pressure data from the host computer.

[0079] Analyze the target oil pressure data.

[0080] Collect oil pressure and oil temperature.

[0081] The target duty cycle is calculated using PID control based on the actual oil pressure and the target oil pressure.

[0082] The duty cycle is output to the PWM pin to control the solenoid valve.

[0083] The collected actual oil pressure and oil temperature are sent to the host computer via serial port.

[0084] The host computer is used to execute the following steps:

[0085] Send the target hydraulic pressure data via serial port.

[0086] Receive oil pressure and oil temperature data sent by the lower-level machine.

[0087] Search for matching oil pressure and oil temperature data.

[0088] It displays the oil pressure and oil temperature data.

Figure 7 As shown, the piston cooling nozzle oil injection quantity control device 600 includes a receiving and acquisition module 601, a calculation module 602, and a control module 603.

[0090] The receiving and acquisition module 601 is used to receive target pressure data for the piston cooling nozzle and acquire current pressure data of the piston cooling nozzle; the calculation module 602 is used to obtain the target duty cycle based on the target pressure data and the current pressure data; and the control module 603 is used to control the amount of oil injected through the piston cooling nozzle based on the target duty cycle.

[0091] In another exemplary embodiment, the control module 603 includes a signal generation unit and a control unit, wherein the signal generation unit is used to generate a PWM signal based on a target duty cycle; the control unit is used to control the opening degree of a proportional solenoid valve based on the PWM signal, wherein the proportional solenoid valve is used to control the amount of oil injected through the piston cooling nozzle.

[0092] In another exemplary embodiment, the piston cooling nozzle oil injection quantity control device 600 provided in this embodiment further includes a power amplification module and a first transmission module, wherein the power amplification module is used to amplify the power of the PWM signal; and the first transmission module is used to send the amplified PWM signal to the proportional solenoid valve.

[0093] In another exemplary embodiment, the receiving and acquisition module 601 is used to detect current pressure data via a pressure sensor disposed at the piston cooling nozzle.

[0094] In another exemplary embodiment, the piston cooling nozzle oil injection quantity control device 600 provided in this embodiment further includes a detection module and a second sending module, wherein the detection module is used to detect the oil temperature data at the piston cooling nozzle; the second sending module is used to send the oil temperature data and current pressure data to the host computer so that the host computer can display the oil temperature data and current pressure data.

[0095] In another exemplary embodiment, the piston cooling nozzle oil injection quantity control device 600 provided in this embodiment further includes a determining module and a third sending module, wherein the determining module is used to determine the current oil injection quantity flowing through the piston cooling nozzle based on oil temperature data and oil pressure data; the third sending module is used to send the current oil injection quantity to the host computer so that the host computer can display the current oil injection quantity.

[0096] In another exemplary embodiment, the determining module is used to match the oil temperature data and current pressure data with a pre-built fuel injection quantity data table to determine the oil flow rate. The fuel injection quantity data table includes multiple sets of oil temperature data, pressure data, and corresponding fuel injection quantity data.

Figure 8 As shown, the fuel injection quantity control device for the piston cooling nozzle includes a pressure sensor, a temperature sensor, a proportional solenoid valve, a PID calculation processor, a PWM signal generator, and a MOSFET. The temperature sensor and the pressure sensor are connected to the piston cooling nozzle.

[0099] The temperature sensor is used to detect the temperature of the oil flowing through the piston cooling nozzle, and the pressure sensor is used to detect the temperature and pressure of the oil flowing through the piston cooling nozzle.

[0100] The system comprises a PID processor, a PWM signal generator, a MOSFET, and a proportional solenoid valve connected in sequence, with the proportional solenoid valve connected to the piston cooling nozzle. The PID processor receives target pressure data and current pressure data for the piston cooling nozzle; it then performs PID calculations on the target and current pressure data to obtain the target duty cycle.

[0101] A PWM signal generator is used to generate a PWM signal based on a target duty cycle, and a MOSFET is used to amplify the power of the PWM signal. The amplified PWM signal is then sent to a proportional solenoid valve. The proportional solenoid valve determines its opening degree based on the amplified PWM signal, thereby controlling the amount of fuel injected through the piston cooling nozzle.
