[0046] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0047] Figure 1This is a flowchart illustrating an engine control method in a cold environment according to an embodiment of the present invention. This embodiment is applicable to engine operation and can be executed by an engine control device for cold environments. This engine control device can be implemented in hardware and / or software. The engine includes a cylinder block, a second oil tank surrounding the surface of the cylinder block, and a second oil tank connected to a first oil tank. Both the first and second oil tanks are used to hold lubricating oil. The second oil tank is located close to the cylinder block. Engine combustion generates heat, causing the cylinder block to heat up. The cylinder block can heat the lubricating oil in the second oil tank. The first and second oil tanks are connected, and a solenoid valve is installed between them to control the flow of lubricating oil, enabling lubricating oil exchange and ensuring the performance of the lubricating oil in low-temperature environments, thereby ensuring the reliability of engine operation. Figure 1 As shown, the method includes:

[0048] S101, Start the engine.

[0049] S102, Obtain engine environmental status information.

[0050] When an engine uses hydrogen as fuel, the water content increases, especially in cold environments, where the amount of condensate produced will further increase. This condensate will enter the lubricating oil, causing it to emulsify and thus affecting the normal operation of the engine. Therefore, it is necessary to obtain the engine's environmental status information in a timely manner to facilitate subsequent adjustments and controls and ensure the normal operation of the engine.

[0051] S103, obtain the first temperature information of the first oil tank and the second temperature information of the second oil tank based on the environmental status information.

[0052] The process involves obtaining the first temperature information of the lubricating oil in the first oil tank and the second temperature information of the lubricating oil in the second oil tank. Typically, the first oil tank is the main oil tank and the second oil tank is the auxiliary oil tank. This allows for subsequent adjustments to the operating status of the first and second oil tanks based on the engine's environmental conditions, thereby reducing the emulsifying effect of condensate on the lubricating oil.

[0053] S104, determine the operating status information of the first oil tank and the second oil tank based on the first temperature information and the second temperature information, so as to control the operating status of the engine.

[0054] Specifically, the working states of the first oil tank and the second oil tank are adjusted according to the first temperature information and the second temperature information, so as to separate the oil-water mixture generated in the cold environment and the normal waterless lubricating oil and supply them to the engine, reduce the emulsification effect of liquid water on the engine oil, and improve the engine reliability in low temperature environment.

[0055] This invention, through the following steps during engine operation: acquiring environmental state information of the engine; acquiring first temperature information of the first fuel tank and second temperature information of the second fuel tank based on the environmental state information; and then determining the operating state information of the first and second fuel tanks, thereby controlling the engine's operating state and improving the reliability of engine operation in low-temperature environments.

[0056] Optional, Figure 2 A flowchart of another engine control method in a cold environment provided by an embodiment of the present invention is shown below. Figure 2 As shown, the method includes:

[0057] S201, Start the engine.

[0058] S202, Determine whether water vapor is generated during engine operation; if yes, proceed to step S204; if no, proceed to step S203.

[0059] S203 indicates that the engine is in normal operating condition.

[0060] The system determines whether water vapor is generated during engine operation, which can condense into water in the cold environment and affect the performance of the lubricating oil in the fuel tank. If no water vapor is generated, the engine is in normal operation and continues to operate in the current mode. If water vapor is generated, the operating status of the first and second fuel tanks needs to be adjusted accordingly to ensure the performance of the lubricating oil and thus the reliability of the engine in cold environments. In addition, the second fuel tank is equipped with a one-way valve that can be opened to discharge high-pressure water vapor, thereby ensuring the normal operation of the engine.

[0061] S204, Obtain the first temperature information of the first oil tank and the second temperature information of the second oil tank.

[0062] S205, determine the operating status information of the first oil tank and the second oil tank based on the first temperature information and the second temperature information, so as to control the operating status of the engine.

[0063] This invention determines the current environmental state of the engine by judging whether water vapor is generated during engine operation, and obtains the first temperature information of the first fuel tank and the second temperature information of the second fuel tank; thereby determining the working state information of the first fuel tank and the second fuel tank to control the engine's operating state and improve the reliability of engine operation in low-temperature environments.

[0064] Optional, Figure 3 A flowchart of another engine control method in a cold environment provided by an embodiment of the present invention is shown below. Figure 3 As shown, the method includes:

[0065] S301, Start the engine.

[0066] S302, Determine whether water vapor is generated during engine operation; if yes, proceed to step S304; if no, proceed to step S303.

[0067] S303 indicates that the engine is in normal operating condition.

[0068] S304, obtain the first temperature of the lubricating oil in the first oil tank and the second temperature of the lubricating oil in the second oil tank.

[0069] Specifically, the system obtains the first temperature of the lubricating oil in the first oil tank and the second temperature of the lubricating oil in the second oil tank. The second oil tank is in contact with the cylinder block, and the second oil tank exchanges energy with the cylinder block. The cylinder block can be used to heat the lubricating oil, quickly raising the oil temperature. The second oil tank is used to assist in regulating the oil temperature, so that the first and second oil tanks can operate in the optimal state, ensuring the normal operation of the engine in low-temperature environments.

[0070] S305 determines the operating status information of the first and second oil tanks based on the first and second temperatures to control the engine's operating status.

[0071] This invention determines the current environmental state of the engine by judging whether water vapor is generated during engine operation, obtains the first temperature of the lubricating oil in the first oil tank and the second temperature of the lubricating oil in the second oil tank, and then determines the working state information of the first oil tank and the second oil tank to control the engine's operating state and improve the reliability of engine operation in low-temperature environments.

[0072] Optional, Figure 4 A flowchart of another engine control method in a cold environment provided by an embodiment of the present invention is shown below. Figure 4 As shown, the method includes:

[0073] S401, start the engine.

[0074] S402, Determine whether water vapor is generated during engine operation; if yes, proceed to step S404; if no, proceed to step S403.

[0075] S403 indicates that the engine is in normal operating condition.

[0076] S404, obtain the first temperature of the lubricating oil in the first oil tank and the second temperature of the lubricating oil in the second oil tank.

[0077] S405, determine whether the first temperature is lower than the first preset temperature; if yes, proceed to step S406; if no, proceed to step S407.

[0078] S406, the second fuel tank is started.

[0079] The first preset temperature can be set according to actual design requirements. This embodiment of the invention does not impose specific limitations; for example, the first preset temperature can be 25°C. When the first temperature of the lubricating oil in the first oil tank is lower than the first preset temperature, the lubricating oil temperature in the first oil tank is low, affecting the normal operation of the engine. Therefore, a second oil tank is needed to provide lubricating oil to the engine. At this time, the first oil tank can stop working or continue working, exchanging lubricating oil between the first and second oil tanks. This allows the warmer lubricating oil from the second oil tank to enter the first oil tank, raising the temperature of the lubricating oil in the first oil tank and ensuring a normal supply of lubricating oil to the engine, thereby ensuring the engine's reliability in cold environments. When the first temperature is not lower than the first preset temperature, it is necessary to further determine the first temperature of the lubricating oil in the first oil tank.

[0080] S407, determine whether the first temperature is less than the second preset temperature, wherein the first preset temperature is less than the second preset temperature; if yes, proceed to step S408; if no, proceed to step S409.

[0081] S408, the first and second fuel tanks start working simultaneously.

[0082] In this embodiment, when the first temperature of the lubricating oil in the first oil tank is lower than the second preset temperature (the second preset temperature can be set according to actual design requirements; this embodiment does not impose a specific limitation, but an exemplary second preset temperature could be 110°C), and the first preset temperature is lower than the second preset temperature, the first and second oil tanks operate simultaneously to provide lubricating oil to the engine. The lubricating oil in the first and second oil tanks circulates to ensure the normal operation of the engine. When the first temperature is not lower than the second preset temperature, it is necessary to further determine the second temperature of the lubricating oil in the second oil tank to ascertain the temperature state of the lubricating oil in the second oil tank.

[0083] S409, determine whether the second temperature is greater than the second preset temperature; if yes, proceed to step S410; if no, proceed to step S404.

[0084] S410, the first oil tank starts working, the second oil tank stops working and the lubricating oil in the second oil tank is emptied.

[0085] Specifically, when the second temperature of the lubricating oil in the second oil tank is greater than the second preset temperature, the lubricating oil temperature in the second oil tank is too high, which will cause the lubricating oil performance to deteriorate. Since the second oil tank is equipped with a one-way valve to discharge water vapor at all times, as the lubricating oil temperature rises, the water vapor will evaporate into the air. At the same time, when the pressure in the oil tank is high, natural venting will also be carried out to ensure the stability of the air pressure. However, when the second temperature of the lubricating oil in the second oil tank exceeds the second preset temperature, it is necessary to control the second oil tank to stop working and drain the lubricating oil in the second oil tank to ensure the reliability of engine operation. When the second temperature of the lubricating oil in the second oil tank is not greater than the second preset temperature, the lubricating oil temperature judgment can be performed normally, and the first temperature of the lubricating oil in the first oil tank and the second temperature of the lubricating oil in the second oil tank can be obtained, thereby ensuring the normal operation of the engine in cold environments.

[0086] This invention determines the current environmental state of the engine by judging whether water vapor is generated during engine operation, obtains the first temperature of the lubricating oil in the first oil tank and the second temperature of the lubricating oil in the second oil tank, and compares the first temperature, the second temperature, the first preset temperature and the second preset temperature to determine the working state information of the first oil tank and the second oil tank, thereby controlling the engine's operating state, avoiding damage to the performance of the lubricating oil, and improving the reliability of engine operation in low-temperature environments.
