Technical Field

[0001] This disclosure relates to the field of vehicle control technology, and in particular to an engine oil filling control method, electronic equipment, and vehicle. Background Technology

[0002] During engine production or assembly, cleanliness issues often arise, and foreign matter on engine components can lead to a decline in engine performance. Engines are typically cleaned manually or with air guns, but residual foreign matter can remain inside the engine (e.g., on relevant components), preventing a thorough cleaning.

[0003] Therefore, how to prevent foreign objects from being present on the inner surface of the engine, which could lead to a decline in engine performance, has become an urgent technical problem to be solved. Summary of the Invention

[0004] In view of this, the purpose of this disclosure is to provide an engine oil filling control method, electronic equipment and vehicle to solve the problem of engine performance degradation caused by foreign matter on the inner surface of the engine in the prior art.

[0005] To achieve the above objectives, the first aspect of this disclosure provides an engine fuel filling control method, the method comprising:

[0006] The opening degree of the pretreatment valve in the pretreatment stage is determined, and the engine control valve is controlled according to the opening degree of the pretreatment valve to pretreat the engine; wherein, the pretreatment is a preparatory process before the engine is filled with oil.

[0007] Determine the opening degree of the oil filling valve during the oil filling stage, and control the engine control valve according to the opening degree of the oil filling valve to fill the engine with oil for cleaning.

[0008] Based on the same inventive concept, a second aspect of this disclosure proposes an electronic device including a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor implements the method described above when executing the computer program.

[0009] Based on the same inventive concept, a third aspect of this disclosure proposes a vehicle that includes the electronic equipment described in the second aspect.

[0010] As can be seen from the above, the engine oil filling control method, electronic equipment, and vehicle disclosed herein are as follows: Before filling the engine with oil, the engine control valve is adjusted to the pre-treatment valve opening, thereby utilizing the engine control valve with the pre-treatment valve opening to achieve the engine preparation process, so as to ensure the smooth progress of the subsequent oil filling process; then, during the oil filling stage, the engine control valve is adjusted to the oil filling valve opening, thereby utilizing the engine control valve with the oil filling valve opening to achieve oil filling of the engine. Oil filling cleans impurities and foreign objects in the engine, ensuring the cleanliness of the engine interior and preventing engine performance degradation or failure to start due to blockage by foreign objects.

Obviously, the accompanying drawings described below are only embodiments of this disclosure. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0016] Figure 4 This is a schematic diagram of the structure of an electronic device according to an embodiment of the present disclosure. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0018] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in the embodiments of this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0019] Based on the description of the background technology, due to the limitations of manufacturing processing level and production equipment precision, the various parts of the newly produced engine will always have surface defects or shape errors. Therefore, the engine usually needs to undergo at least one engine break-in test after assembly.

[0020] Break-in refers to the process by which the properties of the surfaces of each friction pair transition from their initial state to their operational state. Engine break-in tests can eliminate microscopic unevenness generated during machining of various components, minimize the coefficient of friction, and allow the engine to quickly reach a good working condition. At the same time, abnormal phenomena or unusual noises observed during engine break-in tests can help analyze the engine's condition and identify any assembly abnormalities.

[0021] However, in reality, cleanliness issues often arise during engine production or assembly. For example, tiny particles or metal shavings may remain in parts such as the fuel suction valve, fuel rail, or fuel lines. This can prevent the proper handling of harmful gaps between parts caused by thermal deformation, pre-tightening deformation, etc., thus failing to achieve optimal fit. At the same time, when foreign objects accumulate and become stuck in the fuel suction valve, it can cause the valve to malfunction, leading to a decrease in engine performance and, in severe cases, preventing the engine from starting.

[0022] Therefore, before the engine break-in test, i.e., before the engine's first start, it is necessary to remove any small particles or metal debris that may be present on the relevant components. Manufacturers usually use manual visual inspection or air gun spraying methods, but these methods are only effective for cleaning the engine's outer surface and cannot effectively clean the inner surfaces of the components. Since the inside of the fuel suction valve is in contact with fuel, the engine's fuel filling process can be used to flush the inner surfaces of the relevant components, thereby achieving the purpose of cleaning the engine's inner surfaces.

[0023] As mentioned above, how to avoid the presence of foreign objects on the inner surface of the engine that could lead to a decline in engine performance has become an important research question.

[0024] Based on the above description, such as Figure 1 As shown in this embodiment, the engine fuel filling control method includes:

[0025] Step 101: Determine the opening degree of the pretreatment valve in the pretreatment stage, and control the engine control valve according to the opening degree of the pretreatment valve to pretreat the engine; wherein, the pretreatment is a preparatory process before filling the engine with oil.

[0026] In specific implementation, the oil filling control method of the engine proposed in this embodiment is to pre-treat and fill the engine with oil during the first start after the engine is assembled and rolled off the production line. This generates a pressure pulse that impacts the oil suction valve, causing foreign objects such as metal particles to break free from their restraints and be flushed away. This improves the oil suction valve blockage, enhances engine cleanliness, and optimizes the engine's performance and quality, ensuring a successful engine start.

[0027] Before filling the engine with oil, the engine undergoes pretreatment. The pretreatment stage is a preparation phase for pre-treating the engine before filling it with oil. The pretreatment valve opening is the valve opening corresponding to the pretreatment stage.

[0028] There is at least one engine control valve. The determined pretreatment valve opening includes the pretreatment valve opening corresponding to each engine control valve. For example, the engine control valves include valve A and valve B. The pretreatment valve opening corresponding to valve A in the pretreatment stage is determined as a first opening, and the pretreatment valve opening corresponding to valve B in the pretreatment stage is determined as a second opening. Valve A is controlled according to the first opening, and valve B is controlled according to the second opening to achieve engine pretreatment.

[0029] Before step 101, the method further includes: determining whether the fuel filling switch is activated. The fuel filling switch is used to control whether the engine's fuel filling control method is executed. When the fuel filling switch is activated, the engine's fuel filling control method is executed; when the fuel filling switch is closed, the engine's fuel filling control method is not executed.

[0030] Step 102: Determine the opening degree of the oil filling valve during the oil filling stage, and control the engine control valve according to the opening degree of the oil filling valve to fill the engine with oil for cleaning.

[0031] In practice, after pre-treatment of the engine, it is filled with oil. This oil filling process flushes the inner surfaces of engine components, removing residual microparticles, metal shavings, and other impurities and foreign matter. The oil filling valve opening corresponds to the valve opening during the oil filling stage.

[0032] There is at least one engine control valve. The determined filling valve opening includes the filling valve opening corresponding to each engine control valve. For example, the engine control valves include valve A and valve B. The filling valve opening corresponding to valve A during the filling stage is determined to be the third opening, and the filling valve opening corresponding to valve B during the filling stage is determined to be the fourth opening. By controlling valve A according to the third opening and valve B according to the fourth opening, the engine is filled with oil.

[0033] Through the above embodiments, before filling the engine with oil, the engine control valve is adjusted to the pre-treatment valve opening, and the engine preparation process is achieved by using the engine control valve with the pre-treatment valve opening to ensure the smooth progress of the subsequent oil filling process. Then, during the oil filling stage, the engine control valve is adjusted to the oil filling valve opening, and the engine is filled with oil by using the engine control valve with the oil filling valve opening. The oil filling cleans impurities and foreign objects in the engine, ensuring the cleanliness of the engine interior and preventing the engine from deteriorating in performance or failing to start due to blockage by foreign objects.

[0034] In some embodiments, the engine control valve includes: a fuel metering proportional valve and a pressure control valve; step 101 includes:

[0035] Step 1011: Determine the pretreatment valve opening of the fuel metering proportional valve and the pretreatment valve opening of the pressure control valve in the pretreatment stage.

[0036] In practice, the engine control valves include a fuel metering proportional valve (ZME) and a pressure control valve (PCV). The fuel metering proportional valve controls the fuel flow rate, specifically the amount of fuel entering the high-pressure fuel rail. The pressure control valve controls and regulates the fuel pressure.

[0037] By controlling the fuel metering proportional valve and pressure control valve to their respective opening degrees, the flow and pressure within the engine are regulated, thereby achieving engine pretreatment and fuel filling.

[0038] The pretreatment valve openings of the fuel metering proportional valve and the pressure control valve in the pretreatment stage are determined. For example, the pretreatment valve opening of the fuel metering proportional valve in the pretreatment stage is determined to be a first opening, and the pretreatment valve opening of the pressure control valve in the pretreatment stage is determined to be a second opening. The fuel metering proportional valve is controlled according to the first opening, and the pressure control valve is controlled according to the second opening to achieve engine pretreatment.

[0039] The above scheme determines the pretreatment valve openings of both the fuel metering proportional valve and the pressure control valve. This allows for control of the fuel metering proportional valve based on its pretreatment valve opening, and the pressure control valve based on its pretreatment valve opening, thus achieving engine pretreatment. By coordinating the control of these two valves, accurate and efficient engine pretreatment can be achieved.

[0040] In some embodiments, the pretreatment stage includes: an venting stage and / or a pressure building stage; step 1011 includes:

[0041] Step 1011A: Determine that the exhaust valve opening of the fuel metering proportional valve in the exhaust stage is a partially open opening, and the exhaust valve opening of the pressure control valve is a fully open opening; wherein the partially open opening is a preset percentage of the fully open opening.

[0042] In practice, a fuel metering proportional valve typically includes a full opening, a partial opening, and a closed opening. The partial opening is a preset percentage of the full opening. For example, the partial opening includes at least one of the following: a quarter opening (one-quarter of the full opening), a half opening (half of the full opening), and a three-quarters opening (three-quarters of the full opening).

[0043] Generally, pressure control valves include a full opening degree and a closed opening degree.

[0044] For example, the exhaust valve opening of the fuel metering proportional valve in the exhaust stage is determined to be half-open, and the exhaust valve opening of the pressure control valve is determined to be fully open.

[0045] And / or, in step 1011B, determine that the pressure valve opening of the fuel metering proportional valve is partially open during the pressure establishment phase, and that the pressure valve opening of the pressure control valve is closed.

[0046] In practice, for example, the pressure valve opening of the fuel metering proportional valve during the pressure build-up phase is determined to be half-open, and the pressure valve opening of the pressure control valve is determined to be closed.

[0047] When the engine is pre-treated, the pre-treatment stage may only include the exhaust stage; the pre-treatment stage may only include the pressure build-up stage; or the pre-treatment stage may be performed sequentially, including the exhaust stage and the pressure build-up stage.

[0048] Before pre-treating the engine, step 1011A can be used to determine the exhaust valve openings corresponding to the fuel metering proportional valve and pressure control valve during the exhaust phase, in order to perform exhaust treatment on the engine and achieve engine pre-treatment. Alternatively, step 1011B can be used to determine the pressure valve openings corresponding to the fuel metering proportional valve and pressure control valve during the pressure build-up phase, in order to perform pressure build-up treatment on the engine and achieve engine pre-treatment. Another approach is to first determine the exhaust valve openings corresponding to the fuel metering proportional valve and pressure control valve during the exhaust phase using step 1011A, and then determine the pressure openings corresponding to the fuel metering proportional valve and pressure control valve during the pressure build-up phase using step 101B, in order to perform pressure build-up treatment on the engine and achieve engine pre-treatment.

[0049] The above scheme determines that the exhaust valve opening of the fuel metering proportional valve during the exhaust phase is partially open, and the exhaust valve opening of the pressure control valve is fully open. This allows for partial opening of the fuel metering proportional valve and full opening of the pressure control valve during the exhaust phase, achieving fuel filling and exhausting of the high and low pressure circuits. Similarly, the pressure valve opening of the fuel metering proportional valve during the pressure build-up phase is determined to be partially open, and the pressure valve opening of the pressure control valve is determined to be closed. This allows for partial opening of the fuel metering proportional valve and closure of the pressure control valve during the exhaust phase, building pressure in the fuel rail and balancing the pressure before and after the suction valve. Determining the opening of each valve during both the exhaust and pressure build-up phases allows for more efficient and comprehensive engine pre-treatment.

[0050] In some embodiments, step 101 includes:

[0051] Step 101A: Control the fuel metering proportional valve to a partial opening degree and control the pressure control valve to a full opening degree to perform exhaust treatment on the engine.

[0052] In practice, the fuel metering proportional valve is controlled according to the opening of the exhaust valve of the fuel metering proportional valve, and the pressure control valve is controlled according to the opening of the exhaust valve of the pressure control valve to perform exhaust treatment on the engine in order to fill and exhaust the high and low pressure circuits.

[0053] For example, the exhaust valve opening of the fuel metering proportional valve during the exhaust phase is determined to be half-open, and the exhaust valve opening of the pressure control valve is determined to be fully open. The exhaust treatment of the engine is performed by controlling the fuel metering proportional valve to be half-open and the pressure control valve to be fully open.

[0054] And / or, in step 101B, the fuel metering proportional valve is controlled according to a partial opening degree, and the pressure control valve is controlled according to a closed opening degree, to perform pressure build-up processing on the engine.

[0055] In practice, the fuel metering proportional valve is controlled according to the pressure valve opening of the fuel metering proportional valve, and the pressure control valve is controlled according to the pressure valve opening of the pressure control valve. This process is used to build up pressure in the fuel rail so that the pressures at the front and rear ends of the fuel suction valve can be balanced.

[0056] For example, during the pressure build-up phase, the pressure valve opening of the fuel metering proportional valve is determined to be half-open, and the pressure valve opening of the pressure control valve is determined to be closed. By controlling the fuel metering proportional valve to be half-open and the pressure control valve to be closed, pressure build-up is performed on the engine.

[0057] During the engine pretreatment process, exhaust treatment can be performed in step 101A to achieve engine pretreatment. Alternatively, pressure building-up treatment can be performed in step 101B to achieve engine pretreatment. Alternatively, exhaust treatment can be performed first in step 101A, followed by pressure building-up treatment in step 101B to achieve engine pretreatment.

[0058] The above scheme, through the coordinated control of the fuel metering proportional valve and the pressure control valve, enables accurate and efficient engine pretreatment. The pretreatment stage is divided into an exhaust stage and a pressure build-up stage. This process treats the engine's exhaust and pressure, achieving fuel filling and exhaust in the engine's high and low pressure circuits, and establishing pressure in the fuel rail to balance the pressure before and after the fuel suction valve.

[0059] In some embodiments, the engine control valve includes: a fuel metering proportional valve and a pressure control valve; step 102 includes:

[0060] Step 1021: Determine that the fuel metering proportional valve of the fuel filling stage is fully open and that the fuel filling valve of the pressure control valve is fully open.

[0061] In practice, the engine control valves include a fuel metering proportional valve (ZME) and a pressure control valve (PCV). The fuel metering proportional valve controls the fuel flow rate, specifically the amount of fuel entering the high-pressure fuel rail. The pressure control valve controls and regulates the fuel pressure.

[0062] By controlling the fuel metering proportional valve and pressure control valve to their respective opening degrees, the flow and pressure within the engine are regulated, thereby achieving engine pretreatment and fuel filling.

[0063] Determine the filling valve opening of the fuel metering proportional valve and the pressure control valve during the filling phase. For example, determine the filling valve opening of the fuel metering proportional valve to be the third opening and the filling valve opening of the pressure control valve to be the fourth opening. Control the fuel metering proportional valve according to the third opening and control the pressure control valve according to the fourth opening to achieve fuel filling of the engine.

[0064] For example, the filling valve opening of the fuel metering proportional valve during the filling stage is determined to be fully open, and the filling valve opening of the pressure control valve is also determined to be fully open.

[0065] The above scheme determines that the fuel metering proportional valve and the pressure control valve are both fully open during the fuel filling stage, so as to control the fuel metering proportional valve and the pressure control valve to be fully open during the fuel filling stage, thereby achieving fuel filling of the engine.

[0066] In some embodiments, step 102 includes:

[0067] Step 1022: Control the fuel metering proportional valve to its full opening degree, and control the pressure control valve to its full opening degree to fill the engine with fuel.

[0068] In practice, the fuel metering proportional valve is controlled according to the opening degree of the fuel filling valve of the fuel metering proportional valve, and the pressure control valve is controlled according to the opening degree of the fuel filling valve of the pressure control valve to fill the engine with fuel.

[0069] For example, during the filling phase, the filling valve opening of both the fuel metering proportional valve and the pressure control valve is determined to be fully open. The engine is filled with fuel by controlling both the fuel metering proportional valve and the pressure control valve to be fully open.

[0070] The above scheme, through the coordinated control of the fuel metering proportional valve and the pressure control valve, allows for accurate and efficient fuel filling of the engine. Controlling the fuel metering proportional valve to its full opening increases the pressure at the front end of the fuel suction valve. Controlling the pressure control valve to its full opening reduces the pressure at the rear end of the fuel suction valve. This creates a strong pressure differential between the front and rear ends of the fuel suction valve, resulting in a greater lift of the valve and effectively flushing away foreign particles.

[0071] During the initial start-up after engine assembly, the fuel filling process is controlled. By controlling the opening and closing of the fuel metering proportional valve and the pressure control valve, pressure pulses are generated, which impact the fuel suction valve. Foreign objects such as metal particles are released from their restraints and flushed away, improving the fuel suction valve blockage, enhancing engine cleanliness, and bringing the engine performance and quality to an optimal state, thus ensuring a successful engine start-up.

[0072] In some embodiments, step 102 includes:

[0073] Step 102A: Obtain the preprocessing time for the preprocessing stage.

[0074] Step 102B: Determine that the preprocessing time is greater than or equal to a predetermined preprocessing time threshold, and control the engine control valve according to the opening degree of the oil filling valve to fill the engine with oil.

[0075] In practice, during engine pretreatment, the pretreatment time is obtained. When the pretreatment time is greater than or equal to a predetermined pretreatment time threshold, the pretreatment stage is considered complete. Then, the engine control valve is controlled according to the opening of the fuel filling valve to fill the engine with fuel.

[0076] The predetermined pre-processing time threshold is determined by staff based on experience. The pre-processing time threshold is determined according to different engines and the condition of components such as the engine's suction valve, fuel rail, and fuel pump, to prevent false alarms caused by excessive fuel rail pressure or fuel supply.

[0077] The preprocessing time threshold is related to the engine fuel injection quantity and / or fuel pump channel parameters. Specifically, the engine fuel injection quantity and / or fuel pump channel parameters are obtained; based on the engine fuel injection quantity and / or the fuel pump channel parameters, the preprocessing time threshold is determined.

[0078] In addition, timing can be started when the engine enters the pretreatment stage to obtain the pretreatment time. When the pretreatment time reaches a predetermined pretreatment time threshold, the engine enters the oil filling stage to fill it with oil.

[0079] For example, the predetermined pretreatment time threshold is 40 seconds. The timing starts when the engine is pretreated in the pretreatment stage. When the pretreatment time reaches 40 seconds, the oil filling stage begins. The engine control valve is controlled according to the opening of the oil filling valve to fill the engine with oil.

[0080] The pretreatment stage includes: the venting stage and / or the pressure build-up stage.

[0081] For example, when the pretreatment stage is the exhaust stage, the predetermined exhaust time threshold is 40 seconds. Timing begins when the engine is venting exhaust during the exhaust stage; when the timed exhaust time reaches 40 seconds, the oil filling stage begins, and the engine control valve is controlled according to the opening of the oil filling valve to fill the engine with oil.

[0082] When the pretreatment stage is the pressure build-up stage, the predetermined pressure build-up time threshold is 40 seconds. Timing begins when the engine pressure is built up during the pressure build-up stage; when the pressure build-up time reaches 40 seconds, the oil filling stage begins, and the engine control valve is controlled according to the opening degree of the oil filling valve to fill the engine with oil.

[0083] When the pretreatment stage consists of an exhaust stage followed by a pressure build-up stage, the predetermined exhaust time threshold and the predetermined pressure build-up time threshold are both 20 seconds. Timing begins when the engine begins exhausting from the exhaust stage; when the timed exhaust time reaches 20 seconds, the pressure build-up stage begins, and timing resumes again when the engine begins pressure build-up; when the timed pressure build-up time reaches 20 seconds, the oil filling stage begins, and the engine control valve is controlled according to the opening of the oil filling valve to fill the engine with oil.

[0084] The above scheme pre-determines a pre-treatment time threshold. When the pre-treatment time reaches this threshold, the oil filling stage begins. This allows for periodic pre-treatment and oil filling of the engine, providing better control over oil filling and effectively flushing away impurities and foreign matter from the internal surfaces of engine components. The pre-determined pre-treatment time threshold is established by personnel based on the condition of the engine and its components, ensuring accuracy and preventing false alarms caused by excessive fuel rail pressure or fuel supply.

[0085] In some embodiments, after step 102, the method further includes:

[0086] Step 102a: Obtain the oil filling time during the oil filling stage.

[0087] Step 102b: Determine that the oil filling time is greater than or equal to a predetermined oil filling time threshold, and obtain the number of oil filling cycles corresponding to this oil filling stage.

[0088] Step 102c: In response to the number of oil filling cycles being less than a predetermined oil filling cycle threshold, the engine control valve is controlled according to the opening degree of the pretreatment valve to pretreatment the engine.

[0089] Step 102d: In response to the oil filling cycle count being greater than or equal to a predetermined oil filling count threshold, the oil filling control strategy is stopped.

[0090] In practice, when filling the engine with oil, the filling time of the filling stage is obtained. When the filling time is greater than or equal to a predetermined filling time threshold, it indicates that the filling stage is complete, and then it is determined whether the preset number of filling cycles has been completed.

[0091] Specifically, the number of oil filling cycles corresponding to this oil filling stage is obtained. If the number of oil filling cycles is less than a predetermined oil filling cycle threshold, it means that the preset number of oil filling cycles has not been completed. In this case, the engine control valve is controlled according to the opening of the pre-processing valve to pre-process the engine in order to prepare for the next cycle of pre-processing and oil filling. If the number of oil filling cycles is greater than or equal to the predetermined oil filling cycle threshold, it means that the preset number of oil filling cycles has been completed, and the oil filling control strategy is stopped.

[0092] The predetermined oil filling time threshold is determined by the staff based on experience. The pre-treatment time is determined according to different engines and the condition of the engine's suction valve, oil rail, oil pump, and other components to prevent false alarms caused by excessive oil rail pressure or oil supply.

[0093] The fuel filling time threshold is related to the engine fuel injection quantity and / or fuel pump channel parameters. Specifically, the engine fuel injection quantity and / or fuel pump channel parameters are obtained; based on the engine fuel injection quantity and / or the fuel pump channel parameters, the fuel filling time threshold is determined.

[0094] In addition, timing can be started when the engine enters the oil filling stage to obtain the oil filling time. When the oil filling time reaches a predetermined oil filling time threshold, it is determined whether the preset number of oil filling cycles has been completed.

[0095] For example, the predetermined filling time threshold is 20 seconds, and the predetermined filling number threshold is 2 times. Timing begins when the engine enters the filling phase; when the timed filling time reaches 20 seconds, the number of filling cycles corresponding to this filling phase is obtained. When the number of filling cycles is 1, the engine control valve is controlled according to the pre-treatment valve opening to pre-treat the engine in preparation for the next cycle of pre-treatment and filling. When the number of filling cycles is 2, the filling control strategy is stopped.

[0096] The above scheme predetermines a filling time threshold. When the filling time reaches this threshold, it checks whether a preset number of filling cycles has been completed. If the preset number of filling cycles has been completed, the filling control strategy ends; otherwise, it proceeds to the next cycle's pre-processing and filling stages. Performing the preset number of filling cycles ensures the effectiveness of impurity removal during the filling process. The predetermined filling time threshold is established by personnel based on the engine and its related components, ensuring accuracy and preventing false alarms caused by excessive fuel rail pressure or fuel supply.

[0097] Through the above embodiments, before filling the engine with oil, the engine control valve is adjusted to the pre-treatment valve opening, and the engine preparation process is achieved by using the engine control valve with the pre-treatment valve opening to ensure the smooth progress of the subsequent oil filling process. Then, during the oil filling stage, the engine control valve is adjusted to the oil filling valve opening, and the engine is filled with oil by using the engine control valve with the oil filling valve opening. The oil filling cleans impurities and foreign objects in the engine, ensuring the cleanliness of the engine interior and preventing the engine from deteriorating in performance or failing to start due to blockage by foreign objects.

[0098] It should be noted that the embodiments of this disclosure can also be further described in the following ways:

[0099] like Figure 2A As shown, Figure 2A This is a flowchart illustrating the oil filling control strategy according to an embodiment of the present disclosure. The oil filling control strategy includes:

[0100] Step 201: Turn on the oil filling switch.

[0101] Step 202: The timer starts counting.

[0102] Step 203: Control ZME to be half-open and PCV to be fully open.

[0103] Step 204: Determine whether the current timing time is greater than or equal to the set exhaust time, i.e., determine whether Time_1 ≥ set exhaust time; where Time_1 is the timing time in step 203. If Time_1 ≥ set exhaust time is satisfied, proceed to step 205; otherwise, return to step 203.

[0104] Step 205: Control ZME to be half-open and PCV to be closed.

[0105] Step 206: Determine whether the current timing time is greater than or equal to the set pressure setup time, i.e., whether Time_2 ≥ set pressure setup time is satisfied; where Time_2 is the timing time in step 205. If Time_2 ≥ set pressure setup time is satisfied, proceed to step 207; otherwise, return to step 205.

[0106] Step 207: Enable ZME and PCV.

[0107] Step 208: Determine whether the current timing time is not less than the set impact time (i.e., the filling time), that is, determine whether Time_3 ≥ the set impact time; where Time_3 is the timing time in step 207. If Time_3 ≥ the set impact time is satisfied, proceed to step 209; if Time_3 ≥ the set impact time is not satisfied, return to step 207.

[0108] Step 209: Determine if the number of impacts (i.e., the number of oil fillings) is greater than the set number. If the number of impacts is greater than or equal to the set number, end the oil filling control strategy. If the number of oil fillings is less than the set number, return to step 203.

[0109] In the above process, the fuel filling control strategy controls the opening and closing state and opening and closing time of the ZME (fuel metering proportional valve) and PCV (pressure control valve), and uses the strong pressure generated during the opening and closing process to impact foreign objects and impurities on the fuel suction valve, so as to prevent the fuel suction valve from being blocked and ensure the successful starting of the vehicle.

[0110] It should be noted that the exhaust time, pressure build-up time, and impact time set in this oil filling control strategy need to be determined based on the specific engine and the components such as the oil suction valve, oil rail, and oil pump installed in the engine, in order to prevent false alarms caused by excessive oil rail pressure or oil supply.

[0111] Similarly, the number of impacts set in this oil filling control strategy should also be determined according to the actual situation of the engine. While ensuring the effectiveness of pressure impact, the number of impacts should be reduced as much as possible.

[0112] like Figure 2B As shown, Figure 2B This is a schematic diagram of the oil filling control strategy according to an embodiment of the present disclosure.

[0113] Taking a certain engine as an example, its set exhaust time, pressure build-up time, and impact time are 10s, 10s, and 10s respectively, and the set number of impacts is 2.

[0114] When the oil filling switch is turned on, the oil filling control strategy begins. During the 0-10s of the oil filling control strategy, the ZME is partially opened and the PCV is fully opened. This step is to fill and vent the high and low pressure circuits with oil.

[0115] During the 11-20s of the oil filling control strategy, the ZME is kept in a semi-open state and the PCV is closed. This step is to build up pressure in the oil rail so that the pressure at the front and rear ends of the suction valve can be balanced.

[0116] During the 21-30s of the oil filling control strategy, the ZME and PCV are fully opened. The purpose of fully opening the ZME in this step is to increase the pressure at the front end of the suction valve, and the purpose of fully opening the PCV is to reduce the pressure at the rear end of the suction valve. This will create a high pressure difference between the front and rear ends of the suction valve, causing the suction valve to generate a greater lift and flush away foreign particles.

[0117] Meanwhile, to ensure the effectiveness of the process, the above operation is repeated twice to ensure the effectiveness of removing impurities during the oil filling process. The entire oil filling process takes a total of 60 seconds.

[0118] Through the above embodiments, by controlling the opening and closing degree of ZME and PCV during the engine's oil filling process, pressure impact can be generated on the oil suction valve to flush away adhering and residual impurities and foreign objects, preventing the engine from failing to start due to abnormal operating conditions such as blockage.

[0119] It should be noted that the method of this disclosure embodiment can be executed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method of this disclosure embodiment, and the multiple devices will interact with each other to complete the method described.
