The liquid storage device is controlled to deliver engine oil with a predetermined water content to the reaction device. The separated water content corresponding to the water separated in the reaction device can be measured in real time by the measuring device to obtain a first separated water content. When the reaction time of the reaction device is equal to the maximum water separation time of the engine, if the first separated water content is greater than or equal to the separation water content threshold, it indicates that the water separation performance is qualified and the engine oil will not emulsify after water separation, causing engine wear. That is, at the current reaction temperature, the engine can achieve water separation equilibrium by separating the engine oil with the predetermined water content. Since the higher the temperature, the easier it is to achieve water evaporation and separation, the reaction temperature at which the first separated water content is equal to the separation water content threshold is the minimum temperature achieved by the engine when using the engine oil with the predetermined water content. The engine temperature must reach the minimum temperature to avoid engine wear when using the engine oil with the predetermined water content. Otherwise, the water content of the engine oil must be controlled to not reach the predetermined water content. This solves the problem in the prior art of difficulty in determining the water separation performance of the engine after emulsification of the engine oil, which leads to engine wear.

[0030] In this embodiment, a simulation test method for the water separation performance of oil emulsification running on a mobile terminal, a computer terminal or a similar computing device is provided. Figure 2 As shown, the simulation test equipment includes a liquid storage device 10, a reaction device 20 and a measuring device 30 connected in sequence, the liquid storage device 10 is used to store the emulsified engine oil, the reaction device 20 is used to adjust the temperature to simulate the environment of the engine oil when the engine is running, and the measuring device 30 is used to measure the water content separated from the emulsified engine oil. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0031] Figure 3 Flowchart of the simulation test method of the water separation performance of the engine oil after emulsification according to the embodiment of the present application. Figure 3 As shown, the method includes the following steps:

[0032] Step S201, adjusting the reaction temperature of the reaction device;

[0033] Specifically, the reaction device adjusts the temperature to simulate the environment in which the above-mentioned engine oil is located when the engine is running, so as to perform simulation tests on the water separation performance of the engine at different temperatures.

[0034] Step S202, controlling the liquid storage device to deliver the engine oil with a predetermined water content to the reaction device;

[0035] Specifically, if Figure 2 As shown, the above-mentioned simulation test equipment also includes a water storage device 40, a pump 50 and a nozzle 21. A pump 50 is installed on the pipeline between the water storage device 40 and the liquid storage device 10, and a pump 50 is installed on the pipeline between the measuring device 30 and the liquid storage device 10. The water storage device 40 adds water to the engine oil in the liquid storage device 10 through the pump 50 to adjust the water content of the engine oil in the liquid storage device to a predetermined water content. Another pump 50 transports the above-mentioned engine oil with a predetermined water content in the liquid storage device 10 to the above-mentioned reaction device. The engine oil is atomized into different states through the nozzle to simulate the state of the engine oil when it flows through different positions during the operation of the engine, and its atomized components are output from the top of the reaction device to the measuring device.

[0036] Step S203, controlling the measuring device to measure in real time the separated water content corresponding to the water separated in the reaction device to obtain a first separated water content, wherein the separated water content is the ratio of the mass of the separated water to the mass of the water in the engine oil at the predetermined water content;

[0037] Specifically, the water in the reaction device evaporates to the measuring device, and the measuring device measures the separated water to obtain a first separated water content, that is, the ratio of the mass of the separated water to the mass of the water in the engine oil of the predetermined water content.

[0038] Step S204, when the reaction time of the above-mentioned reaction device is equal to the maximum water separation time of the above-mentioned engine and the above-mentioned first separation water content is equal to the separation water content threshold, the current above-mentioned reaction temperature is determined as the lowest temperature of the above-mentioned engine when using the above-mentioned engine oil with the above-mentioned predetermined water content, and the above-mentioned maximum water separation time is the maximum time of the above-mentioned engine to separate water from the above-mentioned engine oil.

[0039] Specifically, generally, the longer the reaction time is, the more water evaporates. When the reaction time of the above-mentioned reaction device is equal to the maximum water separation time of the above-mentioned engine, the first separation water content at this time is the maximum separation water content. If the above-mentioned first separation water content is greater than or equal to the separation water content threshold, water separation balance is achieved. The higher the temperature, the easier it is to achieve water separation balance. If the above-mentioned first separation water content is equal to the separation water content threshold, the current above-mentioned reaction temperature is determined to be the lowest temperature of the above-mentioned engine when using the above-mentioned engine oil with the above-mentioned predetermined water content.

[0040] In the above-mentioned simulation test method for the water separation performance of engine oil after emulsification, the reaction temperature of the reaction device is adjusted to simulate the environment in which the engine oil is located during engine operation. The liquid storage device is controlled to deliver engine oil with a predetermined water content to the reaction device. The separated water content corresponding to the water separated in the reaction device can be measured in real time by the measuring device to obtain a first separated water content. If the reaction time of the reaction device is equal to the maximum water separation time of the engine, and the first separated water content is greater than or equal to the separation water content threshold, it indicates that the water separation performance is qualified and the engine oil will not emulsify after water separation, causing engine wear. In other words, at the current reaction temperature, the engine can achieve water separation equilibrium when separating oil with a predetermined water content. Since higher temperatures facilitate water evaporation and separation, the reaction temperature at which the first separated water content equals the separation water content threshold is the minimum temperature achieved by the engine when using the engine oil with the predetermined water content. The engine temperature must reach the minimum temperature to avoid engine wear when using the engine oil with the predetermined water content. Otherwise, the oil water content must be controlled to not reach the predetermined water content. This solves the problem in the prior art of difficulty in determining the water separation performance of the engine after emulsification, which can lead to engine wear.

[0041] In order to ensure that the water separation performance is qualified, in an optional embodiment, as Figure 4As shown, when the reaction time of the reaction device is equal to the maximum water separation time of the engine and the separated water content is equal to the separated water content threshold, after determining the current reaction temperature as the lowest temperature of the engine when using the engine oil with the predetermined water content, the method includes:

[0042] Step S301, a first control step, controlling the reaction device to deliver the engine oil after water separation to the liquid storage device and controlling the liquid storage device to add a predetermined mass of water when the reaction time of the reaction device is equal to the maximum water separation time of the engine and the separated water content is equal to the separated water content threshold;

[0043] Step S302, an adjustment step, adjusting the reaction temperature of the reaction device;

[0044] Step S303, a second control step, controlling the liquid storage device to deliver the current emulsified oil to the reaction device;

[0045] Step S304, a third control step, controlling the measuring device to measure in real time the separated water content corresponding to the water separated in the reaction device to obtain a second separated water content;

[0046] Step S305, an acquisition step, in which, when the reaction time of the reaction device is equal to the maximum water separation time and the second separated water content is equal to the separated water content threshold, the current reaction temperature is acquired to obtain an updated reaction temperature;

[0047] Step S306, an updating step, in which, when the updated reaction temperature is greater than the minimum temperature, the minimum temperature is updated to the updated reaction temperature;

[0048] Step S307, repeating the first control step, the adjustment step, the second control step, the third control step, the acquisition step and the update step in sequence at least once, until the number of repetitions reaches a predetermined number.

[0049] In the above embodiment, when the reaction time of the above reaction device is equal to the maximum water separation time of the above engine and the above separation water content is equal to the separation water content threshold, the current temperature is the lowest temperature for reaching water separation equilibrium, but one measurement does not represent that the water separation performance is qualified, and water needs to be added multiple times to test the water separation performance multiple times. After multiple additions of water, the water separation performance is qualified, and the maximum value of the lowest temperature measured multiple times is the lowest temperature for reaching the water separation performance, that is, the updated reaction temperature. When the temperature of the engine reaches the updated reaction temperature, it can be ensured that the above-mentioned engine oil with a predetermined water content will not emulsify and affect the lubricating properties of the engine oil, thereby causing engine wear.

[0050] In order to prevent oil stratification, in an optional embodiment, before adjusting the liquid storage temperature of the liquid storage device and the reaction temperature of the reaction device, the method further includes:

[0051] Step S401, adjusting the liquid storage temperature of the liquid storage device until the engine oil with the predetermined water content is stratified;

[0052] Step S402, determining the maximum storage temperature of the liquid at which the engine oil with the predetermined water content in the liquid storage device is not stratified as the maximum ambient temperature of the engine when using the engine oil with the predetermined water content;

[0053] Step S403: When the ambient temperature of the engine is greater than the maximum ambient temperature, an excessively high ambient temperature warning is issued.

[0054] In the above embodiment, there is water in the engine oil and stratification may occur. Of course, whether stratification occurs is related to the ambient temperature. By adjusting the storage temperature of the above-mentioned liquid storage device until the above-mentioned engine oil with the predetermined water content is stratified, the maximum storage temperature at which the above-mentioned engine oil with the predetermined water content is not stratified can be obtained, that is, the maximum ambient temperature. If the ambient temperature exceeds the maximum ambient temperature, an excessively high ambient temperature warning is issued, and the engine oil can be replaced to reduce the water content to prevent the engine oil from stratifying. The predetermined water content corresponds to the maximum ambient temperature.

[0055] In order to prevent the oil from stratifying before testing, in an optional embodiment, before adjusting the liquid storage temperature of the liquid storage device and the reaction temperature of the reaction device, the method further includes:

[0056] Step S501 : adjusting the liquid storage temperature of the liquid storage device so that the liquid storage temperature of the liquid storage device is lower than the maximum ambient temperature.

[0057] In the above embodiment, the liquid storage temperature of the liquid storage device is adjusted so that the liquid storage temperature of the liquid storage device is lower than the maximum ambient temperature, so as to prevent the oil from stratifying before the test and causing inaccurate test results.

[0058] In order to prevent oil stratification before testing, in an optional embodiment, after controlling the measuring device to measure in real time the separated water content corresponding to the water separated in the reaction device to obtain the first separated water content, the method further includes:

[0059] Step S601: When the minimum temperature is greater than the maximum temperature of the engine, it is determined that the engine oil with the predetermined water content cannot reach a water separation equilibrium.

[0060] In the above embodiment, the higher the water content in the engine oil, the higher the temperature requirement for achieving water separation balance. The above minimum temperature is greater than the maximum temperature of the above engine, indicating that the engine temperature cannot reach the minimum temperature for achieving water separation balance. If the engine uses engine oil with a predetermined water content, engine wear problems will occur. Therefore, the engine oil needs to be replaced to reduce the water content in the engine oil.

[0061] To prevent engine wear, in an optional embodiment, when the minimum temperature is greater than the maximum temperature of the engine, after determining that the engine oil having the predetermined water content cannot reach water separation equilibrium, the method includes:

[0062] Step S701, reducing the predetermined water content until the minimum temperature is equal to the maximum temperature of the engine, and determining the current predetermined water content as the maximum water content of the engine oil;

[0063] Step S702: When the water content of the oil in the oil storage device of the engine is greater than the maximum water content, an oil change reminder is issued.

[0064] In the above embodiment, the above-mentioned predetermined water content is reduced, thereby reducing the minimum temperature corresponding to the predetermined water content, until the above-mentioned minimum temperature is equal to the maximum temperature of the above-mentioned engine. The current above-mentioned predetermined water content is the maximum water content of the engine oil of the above-mentioned engine. If the water content of the above-mentioned engine oil storage device is greater than the above-mentioned maximum water content, it indicates that the engine cannot achieve the water separation balance of the engine oil, which will cause engine wear. Therefore, an oil change reminder is issued to prevent engine wear.

[0065] In order to simulate the oil circulation water adding process, an optional embodiment is as follows: Figure 2 As shown, the simulation test equipment further includes a water storage device 40, which is connected to the liquid storage device 10. Step S301 includes:

[0066] Step S3011: Control the water storage device to add the predetermined mass of water into the liquid storage device.

[0067] In the above embodiment, the water storage device 40 adds water to the oil in the liquid storage device 10 through the pump 50, simulating the process of oil circulation and water addition during actual engine operation, so as to further detect the engine's oil-water separation performance during circulation and water addition.

[0068] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the simulation test method for the water separation performance of the engine oil after emulsification of the present application will be described in detail below with reference to specific embodiments.

[0069] This embodiment relates to a specific simulation test method for the water separation performance of engine oil after emulsification, such as Figure 5 As shown, the following steps are included:

[0070] Step S1: Engine oils with different water contents are placed in a liquid storage device, controlled at different temperatures and continuously stirred to simulate the state of the engine oil in the oil pan. The engine oil is pumped to a reaction device via a pumping device. The reaction device can be set to different temperatures and pressures. The engine oil is atomized into different states through a nozzle to simulate the state of the engine oil flowing through different positions during engine operation. The atomized components are output from the top of the reaction device to a measuring device, and the separated water content is measured by the measuring device. At the same time, condensed liquid engine oil is collected at the bottom of the reaction device and returned to the liquid storage device through an oil return pipe.

[0071] Step S2: To simulate the continuous addition of water during the operation of the engine, a water storage device is added, and water can be extracted from the water storage device to the liquid storage device according to different reaction conditions;

[0072] Step S3: Setting an initial water content in the engine oil, and continuously adjusting the liquid storage temperature and reaction temperature to conduct the test until the separated water content is ≥80%, or water separation equilibrium is reached under the condition of continuous water addition. Then, the test is stopped, and the minimum temperature and maximum ambient temperature corresponding to the maximum reaction time are determined;

[0073] Step S4: Then, the test is repeated with different water contents set until the separated water content cannot be ≥80%, or the water separation equilibrium cannot be reached under the condition of continuous water addition, thereby determining the maximum water content in the engine oil, which serves as a control condition to determine whether the engine oil needs to be replaced.

[0074] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

A pump 50 is installed on the pipeline between the water storage device 40 and the liquid storage device 10, and a pump 50 is installed on the pipeline between the measuring device 30 and the liquid storage device 10. The water storage device 40 adds water to the engine oil in the liquid storage device 10 through the pump 50 to adjust the water content of the engine oil in the liquid storage device to a predetermined water content. Another pump 50 transports the above-mentioned engine oil with a predetermined water content in the liquid storage device 10 to the above-mentioned reaction device. The engine oil is atomized into different states through the nozzle to simulate the state of the engine oil when it flows through different positions during the operation of the engine, and its atomized components are output from the top of the reaction device to the measuring device.

[0082] a second control unit 300, configured to control the measuring device to measure in real time a separated water content corresponding to the water separated in the reaction device, to obtain a first separated water content, wherein the separated water content is a ratio of the mass of the separated water to the mass of the water in the engine oil at the predetermined water content;

[0083] Specifically, the water in the reaction device evaporates to the measuring device, and the measuring device measures the separated water to obtain a first separated water content, that is, the ratio of the mass of the separated water to the mass of the water in the engine oil of the predetermined water content.

[0084] The first determination unit 400 is used to determine the current reaction temperature as the lowest temperature of the engine when using the engine oil with the predetermined water content when the reaction time of the reaction device is equal to the maximum water separation time of the engine and the first separation water content is equal to the separation water content threshold. The maximum water separation time is the maximum time for the engine to separate water from the engine oil.

[0085] Specifically, generally, the longer the reaction time is, the more water evaporates. When the reaction time of the above-mentioned reaction device is equal to the maximum water separation time of the above-mentioned engine, the first separation water content at this time is the maximum separation water content. If the above-mentioned first separation water content is greater than or equal to the separation water content threshold, water separation balance is achieved. The higher the temperature, the easier it is to achieve water separation balance. If the above-mentioned first separation water content is equal to the separation water content threshold, the current above-mentioned reaction temperature is determined to be the lowest temperature of the above-mentioned engine when using the above-mentioned engine oil with the above-mentioned predetermined water content.

[0086] In the simulation test device for the water separation performance of emulsified engine oil, the reaction temperature of the reaction device is adjusted to simulate the environment of the engine oil during engine operation. The liquid storage device is controlled to deliver engine oil with a predetermined water content to the reaction device. The separated water content corresponding to the water separated in the reaction device can be measured in real time by the measuring device to obtain a first separated water content. If the reaction time of the reaction device is equal to the maximum water separation time of the engine, and the first separated water content is greater than or equal to the separation water content threshold, it indicates that the water separation performance is qualified and the engine oil will not emulsify after water separation, causing engine wear. In other words, at the current reaction temperature, the engine can achieve water separation equilibrium when separating oil with the predetermined water content. Since higher temperatures facilitate water evaporation and separation, the reaction temperature at which the first separated water content equals the separation water content threshold is the minimum temperature achieved by the engine when using the engine oil with the predetermined water content. The engine temperature must reach the minimum temperature to avoid engine wear when using the engine oil with the predetermined water content. Otherwise, the oil water content must be controlled to not reach the predetermined water content. This solves the problem in the prior art of difficulty in determining the water separation performance of the engine after emulsification, which can lead to engine wear.

[0087] In order to ensure that the water separation performance is qualified, in an optional embodiment, as Figure 4 As shown, the above device includes:

[0088] a third control unit, configured to, when the reaction time of the reaction device is equal to the maximum water separation time of the engine and the separated water content is equal to the separation water content threshold, determine the current reaction temperature as the lowest temperature of the engine when the engine oil with the predetermined water content is used, and then execute a first control step of controlling the reaction device to transport the engine oil after water separation to the liquid storage device and controlling the liquid storage device to add a predetermined mass of water, when the reaction time of the reaction device is equal to the maximum water separation time of the engine and the separated water content is equal to the separation water content threshold;

[0089] A second adjusting unit is used for adjusting the reaction temperature of the reaction device in the adjustment step;

[0090] a fourth control unit, configured to execute the second control step, controlling the liquid storage device to deliver the current emulsified oil to the reaction device;

[0091] a fifth control unit, configured to control the measuring device to measure in real time the separated water content corresponding to the water separated from the reaction device in the third control step, to obtain a second separated water content;

[0092] an acquiring unit, configured to acquire, in an acquiring step, the current reaction temperature to obtain an updated reaction temperature when the reaction time of the reaction device is equal to the maximum water separation time and the second separated water content is equal to the separated water content threshold;

[0093] an updating unit, configured to update the minimum temperature to the updated reaction temperature in the updating step if the updated reaction temperature is greater than the minimum temperature;

[0094] A repeating unit is used to sequentially repeat the first control step, the adjustment step, the second control step, the third control step, the acquisition step and the update step at least once until the number of repetitions reaches a predetermined number.

[0095] In the above embodiment, when the reaction time of the above reaction device is equal to the maximum water separation time of the above engine and the above separation water content is equal to the separation water content threshold, the current temperature is the lowest temperature for reaching water separation equilibrium, but one measurement does not represent that the water separation performance is qualified, and water needs to be added multiple times to test the water separation performance multiple times. After multiple additions of water, the water separation performance is qualified, and the maximum value of the lowest temperature measured multiple times is the lowest temperature for reaching the water separation performance, that is, the updated reaction temperature. When the temperature of the engine reaches the updated reaction temperature, it can be ensured that the above-mentioned engine oil with a predetermined water content will not emulsify and affect the lubricating properties of the engine oil, thereby causing engine wear.

[0096] In order to prevent oil stratification, in an optional embodiment, the above device further includes:

[0097] a third adjusting unit, configured to adjust the liquid storage temperature of the liquid storage device until the engine oil having the predetermined water content is stratified before adjusting the liquid storage temperature of the liquid storage device and the reaction temperature of the reaction device;

[0098] a second determining unit, configured to determine the maximum liquid storage temperature at which the engine oil having the predetermined water content in the liquid storage device is not stratified as the maximum ambient temperature of the engine when using the engine oil having the predetermined water content;

[0099] The first warning unit is used to issue an environmental temperature over-high warning when the ambient temperature of the engine is greater than the maximum ambient temperature.

[0100] In the above embodiment, there is water in the engine oil and stratification may occur. Of course, whether stratification occurs is related to the ambient temperature. By adjusting the storage temperature of the above-mentioned liquid storage device until the above-mentioned engine oil with the predetermined water content is stratified, the maximum storage temperature at which the above-mentioned engine oil with the predetermined water content is not stratified can be obtained, that is, the maximum ambient temperature. If the ambient temperature exceeds the maximum ambient temperature, an excessively high ambient temperature warning is issued, and the engine oil can be replaced to reduce the water content to prevent the engine oil from stratifying. The predetermined water content corresponds to the maximum ambient temperature.

[0101] In order to prevent the oil from stratifying before testing, in an optional embodiment, the device further includes:

[0102] The fourth adjustment unit is used to adjust the liquid storage temperature of the liquid storage device before adjusting the liquid storage temperature of the liquid storage device and the reaction temperature of the reaction device, so that the liquid storage temperature of the liquid storage device is lower than the maximum ambient temperature.

[0103] In the above embodiment, the liquid storage temperature of the liquid storage device is adjusted so that the liquid storage temperature of the liquid storage device is lower than the maximum ambient temperature, so as to prevent the oil from stratifying before the test and causing inaccurate test results.

[0104] In order to prevent the oil from stratifying before testing, in an optional embodiment, the device further includes:

[0105] The third determination unit is used to control the above-mentioned measuring device to measure the separated water content corresponding to the water separated in the above-mentioned reaction device in real time, and after obtaining the first separated water content, when the above-mentioned minimum temperature is greater than the maximum temperature of the above-mentioned engine, determine that the above-mentioned engine oil with the above-mentioned predetermined water content cannot reach the water separation equilibrium.

[0106] In the above embodiment, the higher the water content in the engine oil, the higher the temperature requirement for achieving water separation balance. The above minimum temperature is greater than the maximum temperature of the above engine, indicating that the engine temperature cannot reach the minimum temperature for achieving water separation balance. If the engine uses engine oil with a predetermined water content, engine wear problems will occur. Therefore, the engine oil needs to be replaced to reduce the water content in the engine oil.

[0107] In order to prevent engine wear, in an optional embodiment, the above device includes:

[0108] a fourth adjusting unit, configured to, when the minimum temperature is greater than the maximum temperature of the engine, determine that the engine oil with the predetermined water content cannot reach water separation equilibrium, reduce the predetermined water content until the minimum temperature is equal to the maximum temperature of the engine, and determine the current predetermined water content as the maximum water content of the engine oil;

[0109] The second warning unit is used to issue an oil change reminder when the water content of the oil in the oil storage device of the engine is greater than the maximum water content.

[0110] In the above embodiment, the above-mentioned predetermined water content is reduced, thereby reducing the minimum temperature corresponding to the predetermined water content, until the above-mentioned minimum temperature is equal to the maximum temperature of the above-mentioned engine. The current above-mentioned predetermined water content is the maximum water content of the engine oil of the above-mentioned engine. If the water content of the above-mentioned engine oil storage device is greater than the above-mentioned maximum water content, it indicates that the engine cannot achieve the water separation balance of the engine oil, which will cause engine wear. Therefore, an oil change reminder is issued to prevent engine wear.

[0111] In order to simulate the oil circulation water adding process, an optional embodiment is as follows: Figure 2 As shown, the simulation test device further includes a water storage device 40, which is connected to the liquid storage device 10. The third control unit includes:

[0112] The control module is used to control the water storage device to add the predetermined mass of water to the liquid storage device.

[0113] In the above embodiment, the water storage device 40 adds water to the oil in the liquid storage device 10 through the pump 50, simulating the process of oil circulation and water addition during actual engine operation, so as to further detect the engine's oil-water separation performance during circulation and water addition.

[0114] The simulation test device for the water separation performance of emulsified engine oil includes a processor and memory. The first adjustment unit, first control unit, second control unit, and first determination unit are all stored as program units in the memory. The processor executes the program units stored in the memory to implement the corresponding functions. All of the above modules are located in the same processor; alternatively, the above modules can be located in different processors in any combination.

[0115] The processor includes a kernel, which retrieves the corresponding program unit from memory. One or more kernels can be configured, and kernel parameters can be adjusted to address the prior art issue of difficulty determining the water separation performance of an engine after oil emulsification, which can lead to engine wear.

[0148] From the above description, it can be seen that the above embodiments of the present application achieve the following technical effects:

[0149] 1) In the simulation test method for the water separation performance of engine oil after emulsification of the present application, the reaction temperature of the reaction device is adjusted to simulate the environment of the engine oil during engine operation. The liquid storage device is controlled to deliver engine oil with a predetermined water content to the reaction device. The separated water content corresponding to the water separated in the reaction device can be measured in real time by a measuring device to obtain a first separated water content. If the reaction time of the reaction device is equal to the maximum water separation time of the engine, and the first separated water content is greater than or equal to the separation water content threshold, it indicates that the water separation performance is qualified and the engine oil will not emulsify and cause engine wear after water separation. In other words, at the current reaction temperature, the engine can achieve water separation equilibrium when separating oil with a predetermined water content. Since higher temperatures make it easier to achieve water evaporation and separation, the reaction temperature at which the first separated water content equals the separation water content threshold is the minimum temperature achieved by the engine when using the engine oil with the predetermined water content. The engine temperature must reach the minimum temperature to avoid engine wear when using the engine oil with the predetermined water content. Otherwise, the water content of the engine oil must be controlled to not reach the predetermined water content. This solves the problem in the prior art of difficulty in determining the water separation performance of the engine after emulsification of the engine oil, which can lead to engine wear.

[0150] 2) In the simulation test device for the water separation performance of the emulsified engine oil of the present application, the reaction temperature of the reaction device is adjusted to simulate the environment of the engine oil during engine operation. The liquid storage device is controlled to deliver engine oil with a predetermined water content to the reaction device. The separated water content corresponding to the water separated in the reaction device can be measured in real time by the measuring device to obtain a first separated water content. If the reaction time of the reaction device is equal to the maximum water separation time of the engine, and the first separated water content is greater than or equal to the separation water content threshold, it indicates that the water separation performance is qualified and the engine oil will not emulsify after water separation, causing engine wear. In other words, at the current reaction temperature, the engine can achieve water separation equilibrium when separating oil with a predetermined water content. Since higher temperatures facilitate water evaporation and separation, the reaction temperature at which the first separated water content equals the separation water content threshold is the minimum temperature achieved by the engine when using the engine oil with the predetermined water content. The engine temperature must reach the minimum temperature to avoid engine wear when using the engine oil with the predetermined water content. Otherwise, the oil water content must be controlled to not reach the predetermined water content. This solves the problem in the prior art of difficulty in determining the water separation performance of the engine after emulsification of the engine oil, which can lead to engine wear.
