Description

Technical Field

[0001] The present application relates to the field of engine technology, and in particular to an oil mist concentration control system, method, device and storage medium. Background Art

[0002] Methanol engines produce formic acid, water and other components during the combustion process. In actual applications, a small amount of formic acid and water will enter the crankcase of the methanol engine through the combustion chamber and mix with the engine oil in the crankcase, causing oil emulsification. This not only affects the service life of the engine oil, but also reduces the performance of the engine oil, seriously affecting the reliability of the engine.

[0003] In order to solve the above problems, in the related art, the crankcase is connected to an intercooler, and the intercooler is used to supplement high-pressure air to the crankcase, thereby increasing the crankcase awakening efficiency and accelerating the discharge of formic acid and water vapor. However, the amount of high-pressure air supplemented to the crankcase in the above method changes with the engine load. Since the volume of the crankcase does not change, the air pressure in the crankcase changes with the change of the air volume, resulting in the air pressure entering the crankcase being in a fluctuating state, and the oil mist concentration in the crankcase also fluctuates accordingly, and it is still impossible to effectively avoid oil emulsification during the operation of the engine.

[0086] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the technical solution of the present application, rather than all of the embodiments. Based on the embodiments recorded in the application documents, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the technical solution of the present application.

[0087] The following is an introduction to some concepts involved in the embodiments of the present application.

[0088] Crankcase: It is a closed space at the bottom of the engine that contains the crankshaft, connecting rods and other related mechanical parts. Its main function is to accommodate the above parts and provide them with necessary lubrication and cooling. In addition, the crankcase is also responsible for sealing to prevent oil leakage.

[0089] Oil emulsification: refers to the phenomenon that cooling water or water-based substances enter the engine oil. The lubricating performance of the emulsified oil is reduced, and the water in the emulsified oil will accelerate the corrosion of metal parts, thereby affecting the performance and reliability of the engine.

[0090] Intercooler: It is a device used to cool the intake system of an internal combustion engine. Its main function is to reduce the temperature of the air entering the engine cylinder in a supercharged engine. When the air is compressed, its temperature rises, and the higher intake temperature causes the air density to decrease, thereby reducing the efficiency and power output of the engine. By using an intercooler to reduce the intake temperature, the density of the air can be increased, thereby increasing the charging efficiency of the engine, and ultimately increasing the power output of the engine and improving fuel economy. In the embodiment of the present application, high-pressure air is added to the crankcase through the intercooler to avoid the problem of oil emulsification in the crankcase.

[0091] The following is a brief introduction to the design concept of the embodiment of the present application:

[0092] Methanol engines produce formic acid, water and other components during the combustion process. In actual applications, a small amount of formic acid and water will enter the engine crankcase through the combustion chamber and mix with the engine oil in the crankcase, causing the engine oil to emulsify. Figure 1 As shown, it is a schematic diagram of an engine oil emulsification provided by an embodiment of the present application. Engine oil emulsification not only affects the service life of the engine oil, but also reduces the performance of the engine oil, seriously affecting the reliability of the engine.

[0093] In order to solve the above problems, in the related technology, the intercooler is directly connected to the crankcase of the engine, and the high-pressure air supplied to the crankcase is supplied through the intercooler to increase the crankcase ventilation efficiency and accelerate the discharge of formic acid and water vapor. Figure 2 As shown in FIG. 1 , it is a schematic diagram of a related technology provided by an embodiment of the present application. However, the amount of high-pressure air added to the crankcase in the above method changes with the engine load. Since the crankcase volume does not change, the air pressure in the crankcase changes with the change of the air amount, resulting in the air pressure entering the crankcase being in a fluctuating state, and the oil mist concentration in the crankcase also fluctuates accordingly, and it is still impossible to effectively avoid oil emulsification during the operation of the engine.

[0094] In view of this, the embodiments of the present application provide an oil mist concentration control system, method, device and storage medium. By connecting a one-way stop valve between the intercooler and the crankcase and setting an oil mist concentration sensor on the crankcase, the oil mist concentration in the crankcase is continuously detected, and an oil mist concentration signal representing the oil mist concentration is sent to the controller. The controller generates a control signal based on the oil mist concentration signal to adjust the working state of the one-way stop valve, thereby controlling the flow rate of high-pressure air supplemented by the intercooler to the crankcase, and controlling the oil mist concentration in the crankcase within a reasonable range.

[0095] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.

[0096] like Figure 3 , which is a schematic diagram of an oil mist concentration control system provided in an embodiment of the present application. The oil mist concentration control system includes an intercooler 301 , a crankcase 302 , an oil mist concentration sensor 303 , a controller 304 and a one-way stop valve 305 .

[0097] The crankcase 302 is provided with an oil mist concentration sensor 303, a first end of a one-way stop valve 305 is connected to the intercooler 301, a second end of the one-way stop valve 305 is connected to the controller 304, a third end of the one-way stop valve 305 is connected to the crankcase 302, and the controller 304 is also connected to the oil mist concentration sensor 303;

[0098] Among them, the intercooler 301 is used to supplement high-pressure air to the crankcase 302 when the engine is running;

[0099] The oil mist concentration sensor 303 is used to detect the oil mist concentration in the crankcase 302, generate an oil mist concentration signal representing the oil mist concentration, and send the oil mist concentration signal to the controller 304;

[0100] The controller 304 is used to generate a control signal for the one-way stop valve 305 according to the oil mist concentration signal, and send the control signal to the one-way stop valve 305;

[0101] The one-way stop valve 305 is used to adjust the working state according to the control signal to change the flow rate of the high-pressure air supplemented by the intercooler 301 to the crankcase 302 .

[0102] In an optional implementation, the oil mist concentration sensor 303, the controller 304 and the one-way stop valve 305 can communicate with each other through a communication network.

[0103] In an optional implementation, the communication network is a wired network or a wireless network.

[0104] The oil mist concentration control method provided by the exemplary embodiment of the present application is described below in combination with the application scenarios described above and with reference to the accompanying drawings. It should be noted that the above application scenarios are only shown to facilitate understanding of the spirit and principles of the present application, and the implementation methods of the present application are not limited in this regard.

[0105] Figure 4 A flow chart of an oil mist concentration control method provided in an embodiment of the present application is shown. Figure 4 As shown, the method may include the following steps S41 to S44:

[0106] S41: Intercooler, used to add high-pressure air to the crankcase when the engine is running.

[0107] S42: an oil mist concentration sensor, used for detecting the oil mist concentration in the crankcase, generating an oil mist concentration signal representing the oil mist concentration, and sending the oil mist concentration signal to the controller.

[0108] Specifically, when the engine is running, the oil mist concentration sensor detects the oil mist concentration in the crankcase in real time, and synchronously sends an oil mist concentration control signal representing the oil mist concentration to the controller.

[0109] S43: A controller, used for generating a control signal for the one-way stop valve according to the oil mist concentration signal, and sending the control signal to the one-way stop valve.

[0110] Specifically, the controller receives the oil mist concentration signal detected by the oil mist concentration sensor, generates a control signal according to the oil mist concentration represented by the sensor and a preset concentration threshold, and controls the working state of the one-way stop valve through the control signal, so that the one-way stop valve is opened when the oil mist concentration in the crankcase is high and is closed when the oil mist concentration in the crankcase is low.

[0111] In the embodiment of the present application, when the controller generates a control signal, an optional implementation is as follows:

[0112] Analyze whether the oil mist concentration represented by the oil mist concentration signal reaches a first preset concentration threshold; if the oil mist concentration reaches the first preset concentration threshold, generate an opening control signal for the one-way stop valve; if the oil mist concentration does not reach the first preset concentration threshold, generate a closing control signal for the one-way stop valve.

[0113] Among them, the first preset concentration threshold is a value obtained after multiple experiments. When the oil mist concentration detected by the oil mist concentration sensor reaches the threshold, the controller sends an opening control signal to the one-way stop valve. When the oil mist concentration detected by the oil mist concentration sensor does not reach the threshold, the controller sends a closing control signal to the one-way stop valve to keep the one-way stop valve in a closed state.

[0114] For example, during a detection process, the oil mist concentration sensor detects an oil mist concentration of 1 and sends the corresponding oil mist concentration signal 1 to the controller. After comparing the oil mist concentration 1 with the first preset concentration threshold, the controller determines that the oil mist concentration 1 has reached the first preset concentration threshold, and then generates an opening control signal for the one-way stop valve. Furthermore, the oil mist concentration sensor continues to detect the crankcase, and detects an oil mist concentration of 2 during a certain detection, and sends the corresponding oil mist concentration signal 2 to the controller. After comparing the oil mist concentration 2 with the first preset concentration threshold, the controller determines that the oil mist concentration 1 no longer reaches the first preset concentration threshold, and then generates a closing control signal for the one-way stop valve.

[0115] In addition, considering that the oil mist concentration in the crankcase and the air pressure added to the intercooler will change with the load of the engine, the opening control signal in the embodiment of the present application includes a first opening control signal and a second opening control signal. In an optional implementation, the embodiment of the present application adjusts the opened one-way stop valve in the following manner:

[0116] If the oil mist concentration reaches the first preset concentration threshold and does not reach the second preset concentration threshold, a first opening control signal for the one-way stop valve is generated; if the oil mist concentration reaches the second preset concentration threshold, a second opening control signal for the one-way stop valve is generated;

[0117] Among them, the second preset concentration threshold is greater than the first preset concentration threshold; the first opening control signal and the second opening control signal are used to control at least one of the opening degree and opening duration of the one-way stop valve, and the first opening control signal and the second opening control signal have different degrees of control over the one-way stop valve.

[0118] Specifically, the second preset concentration threshold is also a value obtained through multiple experiments, and both the first preset concentration threshold and the second preset concentration threshold are not fixed.

[0119] For example, during a detection process, the oil mist concentration sensor detects an oil mist concentration of 3, and sends the corresponding oil mist concentration signal 3 to the controller. After comparing the oil mist concentration 3 with the first preset concentration threshold, the controller determines that the oil mist concentration 3 has reached the first preset concentration threshold, and then compares the oil mist concentration 3 with the second preset concentration threshold, and determines that the oil mist concentration 3 has not reached the second preset concentration threshold, and then generates a first opening control signal for the one-way stop valve. Furthermore, the oil mist concentration sensor continues to detect the crankcase, and detects an oil mist concentration of 4 during a certain detection, and sends the corresponding oil mist concentration signal 4 to the controller. After comparing the oil mist concentration 4 with the first preset concentration threshold, the controller determines that the oil mist concentration 4 has reached the first preset concentration threshold, and then compares the oil mist concentration 4 with the second preset concentration threshold, and determines that the oil mist concentration 4 has reached the second preset concentration threshold, and then generates a second opening control signal for the one-way stop valve.

[0120] In the above-mentioned implementation mode, the embodiment of the present application sets a controller so that the one-way stop valve and the oil mist concentration signal are synchronously controlled to ensure synchronization, so that the high-pressure air supplemented by the intercooler to the crankcase can be adjusted in real time according to the oil mist concentration of the crankcase.

[0121] S44: One-way stop valve, used to adjust the working state according to the control signal to change the flow rate of high-pressure air supplemented by the intercooler to the crankcase.

[0122] Specifically, by sending a control signal to the one-way stop valve through the controller, the working state of the one-way stop valve is adjusted in real time, thereby adjusting the flow state of the high-pressure air supplied from the intercooler to the crankcase in real time, thereby achieving dynamic control of the oil mist concentration in the crankcase.

[0123] The working state includes the opening degree and the opening time, and the one-way stop valve can adjust the opening degree and / or the opening time in the opening state according to the control signal.

[0124] In the embodiment of the present application, when the opening of the one-way stop valve is adjusted, an optional implementation method is as follows:

[0125] According to the first opening control signal, the opening is adjusted to a first opening so that the intercooler supplies the high-pressure air at a first flow rate to the crankcase; according to the second opening control signal, the opening is adjusted to a second opening so that the intercooler supplies the high-pressure air at a second flow rate to the crankcase;

[0126] The first opening is smaller than the second opening, and the first flow rate is smaller than the second flow rate.

[0127] Specifically, when the oil mist concentration reaches the first preset concentration threshold but has not reached the second preset concentration threshold, the one-way stop valve, according to the first opening control signal, reduces the amount of high-pressure air supplied from the intercooler to the crankcase, thereby avoiding the occurrence of oil emulsification. Therefore, if the opening of the one-way stop valve is adjusted based on the first opening control signal, the one-way stop valve will be adjusted to the first opening with a smaller opening, at which time the flow rate of high-pressure air supplied from the intercooler to the crankcase is smaller.

[0128] When the oil mist concentration reaches the second preset concentration threshold, the one-way stop valve, according to the second opening control signal, makes the high-pressure air supplied from the intercooler to the crankcase larger, so as to avoid the occurrence of oil emulsification. Therefore, if the opening of the one-way stop valve is adjusted based on the second opening control signal, the one-way stop valve will be adjusted to the second larger opening, at which time, the high-pressure air flow supplied from the intercooler to the crankcase is larger.

[0129] In addition, more preset concentration thresholds and corresponding opening control signals for controlling other openings of the one-way stop valve may be set according to experimental results or experience.

[0130] It should be noted that when only the opening of the one-way stop valve is controlled by the control signal, the same opening time will be opened at the first opening and the second opening. For example, when only the opening is controlled, the first opening time or the second opening time can be opened at different openings by default, etc. At this time, at different openings, the high-pressure air flow of the intercooler to supplement the crankcase is different.

[0131] Similarly, in the embodiment of the present application, when the one-way stop valve adjusts the opening time, an optional implementation method is as follows:

[0132] According to the first opening control signal, the opening duration is adjusted to the first opening duration, so that the intercooler replenishes the third flow of high-pressure air to the crankcase; according to the second opening control signal, the opening duration is adjusted to the second opening duration, so that the intercooler replenishes the fourth flow of high-pressure air to the crankcase;

[0133] Among them, the first opening duration is shorter than the second opening duration, and the third flow rate is shorter than the fourth flow rate.

[0134] It should be noted that the first flow rate and the third flow rate may be the same or different, and the second flow rate and the fourth flow rate may be the same or different.

[0135] Specifically, when the oil mist concentration reaches the first preset concentration threshold but has not yet reached the second preset concentration threshold, the one-way stop valve, according to the first opening control signal, reduces the amount of high-pressure air supplied to the crankcase by the intercooler, thereby avoiding the occurrence of engine oil emulsification. Therefore, if the opening duration of the one-way stop valve is adjusted based on the first opening control signal, the one-way stop valve will be adjusted to the first opening duration, which is shorter. At this time, the flow rate of high-pressure air supplied to the crankcase by the intercooler is smaller, thereby reducing the oil mist concentration in the crankcase to below the first preset concentration threshold.

[0136] When the oil mist concentration reaches the second preset concentration threshold, the one-way stop valve, according to the second opening control signal, allows the intercooler to replenish more high-pressure air to the crankcase, so as to avoid the occurrence of oil emulsification. Therefore, if the opening time of the one-way stop valve is adjusted based on the second opening control signal, the one-way stop valve will be adjusted to the second opening time, which is longer. At this time, the flow rate of high-pressure air replenished from the intercooler to the crankcase is larger, so that the oil mist concentration in the crankcase can be reduced to below the first preset concentration threshold.

[0137] In addition, more preset concentration thresholds and corresponding opening control signals for controlling other opening time lengths of the one-way stop valve may be set according to experimental results or experience.

[0138] It should be noted that when only the opening time of the one-way stop valve is controlled by the control signal, the same opening degree will be opened at the first opening time and the second opening time. For example, when only the opening time is controlled, the first opening degree or the second opening degree can be opened at different opening times by default, etc. At this time, at different opening times, the high-pressure air flow of the intercooler to supplement the crankcase is different.

[0139] In addition, when the one-way stop valve receives the first opening control signal, it can also control the opening degree and the opening time at the same time, so that the one-way stop valve opens for the first opening time at the first opening degree; similarly, when the one-way stop valve receives the second opening control signal, it can also control the opening degree and the opening time at the same time, so that the one-way stop valve opens for the second opening time at the second opening degree.

[0140] The embodiment of the present application provides an oil mist concentration control system, method, device and storage medium. By connecting a one-way stop valve between the intercooler and the crankcase and setting an oil mist concentration sensor on the crankcase, the oil mist concentration in the crankcase is continuously detected, and an oil mist concentration signal representing the oil mist concentration is sent to a controller. The controller generates a control signal to adjust the working state of the one-way stop valve according to the oil mist concentration signal, thereby controlling the flow rate of high-pressure air supplemented by the intercooler to the crankcase and controlling the oil mist concentration in the crankcase within a reasonable range. The controller controls the flow rate or flow rate of high-pressure air allowed to pass through the one-way stop valve through the difference between the oil mist signal in the crankcase and the preset oil mist concentration signal threshold, so that the one-way stop valve and the oil mist concentration sensor work in conjunction.

[0141] In addition, the embodiments of the present application require relatively minor changes to existing components. It is only necessary to add pin functions to the controller and connect the oil mist concentration sensor and the one-way stop valve to implement the above-mentioned oil mist concentration control method.
