Background Art

[0002] The radiator is a crucial component of the engine cooling system, responsible for maintaining the engine temperature within a reasonable range. During engine operation, parts in contact with the hot fuel gas are heated. Insufficient cooling can lead to abnormal combustion, oil deterioration, and increased component wear, impacting engine performance, fuel efficiency, and reliability. However, excessive cooling removes too much heat, resulting in poor mixture formation, fuel oil dilution, and increased component wear. Therefore, the cooling system must be able to adjust its cooling capacity to maintain the optimal engine temperature under various operating conditions—in other words, to achieve precise cooling of the engine.

[0003] In the relevant technology, the cooling system solutions currently used in the market are usually based on a water pump, a thermostat and a water tank. The thermostat is used to adjust the two branches of the radiator's large circulation and the bypass small circulation. This type of cooling system is difficult to meet the current engine's requirements for precise temperature control and cannot achieve the engine's rapid heating requirements during cold start.

[0031] As mentioned in the background technology section, the water tank is an important component of the engine cooling system, and the water tank is responsible for maintaining the temperature of the engine within a reasonable range. When the engine is running, the parts in contact with the high-temperature fuel gas are heated. Insufficient cooling will lead to abnormal combustion, oil deterioration, increased wear of parts, and the engine's power, economy and reliability will be affected. However, excessive cooling will take away too much heat, resulting in poor mixture formation, oil dilution by fuel, and increased wear of parts. Therefore, the cooling system needs to change its cooling capacity in a timely manner to maintain the engine at the optimal temperature under multiple working conditions, that is, to achieve precise cooling of the engine.

[0032] In the process of realizing the present invention, the applicant discovered that in the relevant technology, the cooling system solutions currently used on the market are usually based on a water pump, a thermostat and a water tank, and the thermostat is used to adjust the two branches of the radiator's large circulation and the bypass small circulation. This type of cooling system is difficult to meet the current engine's requirements for precise temperature control and cannot achieve the engine's rapid heating requirements during cold start.

[0033] Therefore, the present invention can adjust the cooling effect of the temperature control system according to the operating temperature of the target point of the engine, eliminate the thermostat, integrate the function of the thermostat into the water tank, reduce the failure rate of the temperature control system, solve the problems of engine starting difficulty and emission in winter, and reduce production costs.

[0051] refer to Figure 3 , which is a flow chart of a method for controlling a cooling liquid temperature regulation system according to some embodiments of the present invention.

[0052] like Figure 3 As shown, the control method of the coolant temperature regulation system according to the embodiment of the present invention may include the following steps: S301, obtaining the operating temperature of the target engine point and determining whether the operating temperature is within the optimal temperature range.

[0053] Specifically, the operating temperature of the target point of the engine can be detected by a temperature sensor installed on the engine. After obtaining the operating temperature of the target point of the engine, it is determined whether the operating temperature of the target point of the engine is within the optimal temperature range. When the operating temperature of the target point of the engine is within the optimal temperature range, it can indicate that the combustion of the engine is normal and the mixture is well formed.

[0054] S302 : In response to the operating temperature not being within the optimal temperature range, determining whether the operating temperature is higher than a preset temperature threshold, wherein the preset temperature threshold may be calibrated according to actual conditions.

[0055] Specifically, when the operating temperature of the engine target point is not within the optimal temperature range, it may indicate that the operating temperature of the engine target point is higher or lower, and it is determined again whether the operating temperature of the engine target point is higher than a preset temperature threshold.

[0056] S303, in response to the operating temperature being higher than the preset temperature threshold, controlling the first outlet of the first three-way solenoid valve to close, and opening the first inlet and the second outlet; controlling the second inlet and the third outlet of the first four-way solenoid valve to open, and closing the third inlet and the fourth outlet.

[0057] Specifically, when the operating temperature of the engine target point is higher than the preset temperature threshold, it may indicate that the operating temperature of the engine target point is high and needs to be cooled. At this time, the first outlet of the first three-way solenoid valve is controlled to be closed, and the first inlet and the second outlet are opened to prevent the heater from heating the coolant, so that the coolant flows directly to the first cooling pipe. The second inlet and the third outlet of the first four-way solenoid valve are controlled to be opened, and the third inlet and the fourth outlet are closed to direct the coolant in the first cooling pipe to the second cooling pipe, and prevent the coolant remaining in the heating pipe from flowing to the second cooling pipe and the first direct current pipe. This can reduce the temperature of the engine, reduce wear and emissions, and ensure that fuel economy, power output and emissions meet standards.

[0058] In some embodiments of the present invention, the control method for the coolant temperature regulation system further includes: in response to the operating temperature being no higher than a preset temperature threshold, determining whether the engine startup time is less than a preset time threshold; and in response to the startup time being no less than the preset time threshold, controlling the closing of the first outlet of the first three-way solenoid valve and the opening of the first inlet and the second outlet, and controlling the opening of the second inlet and the fourth outlet of the first four-way solenoid valve and the closing of the third inlet and the third outlet. The preset time thresholds may be calibrated according to actual conditions.

[0059] Specifically, when the operating temperature of the engine target point is not higher than the preset temperature threshold, it can be said that the operating temperature of the engine target point is low, and the timer set on the engine can be used to determine whether the engine start time is lower than the preset time threshold. When the engine start time is not lower than the preset time threshold, it can be said that the engine is not in a cold start state. At this time, the first outlet of the first three-way solenoid valve is controlled to close, and the first inlet and the second outlet are opened to prevent the heater from heating the coolant, so that the coolant flows directly to the first cooling pipe, and the second inlet and the fourth outlet of the first four-way solenoid valve are controlled to open, and the third inlet and the third outlet are closed to direct the coolant of the first cooling pipe to the first DC pipe, prevent the coolant of the first cooling pipe from flowing to the second cooling pipe, and prevent the coolant remaining in the heating pipe from flowing to the first DC pipe, thereby further reducing energy consumption.

[0060] In some embodiments of the present invention, the control method of the above-mentioned coolant temperature regulation system also includes: in response to the start-up time being lower than a preset time threshold, controlling the closing of the second outlet of the first three-way solenoid valve, opening the first inlet and the first outlet, controlling the opening of the third inlet and the fourth outlet of the first four-way solenoid valve, and closing the second inlet and the third outlet.

[0061] Specifically, when the engine startup time is lower than a preset time threshold, it can be indicated that the engine is in a cold start state. At this time, the second outlet of the first three-way solenoid valve is controlled to close, and the first inlet and the first outlet are opened to prevent the coolant from flowing into the first cooling pipe. The coolant in the upper water chamber flows into the heating pipe, so that the heater heats the coolant. The third inlet and the fourth outlet of the first four-way solenoid valve are controlled to open, and the second inlet and the third outlet are closed to allow the coolant in the heating pipe to flow into the first DC pipe, preventing the coolant in the heating pipe from flowing into the second cooling pipe. It can be understood that when the engine startup time is lower than the preset time threshold, the coolant in the upper water chamber flows from the heating pipe to the first DC pipe, then from the first DC pipe to the second DC pipe, and finally from the second DC pipe to the lower water chamber.

[0062] In some embodiments of the present invention, the control method of the temperature regulation system of the above-mentioned coolant further includes: in response to the operating temperature not being within the optimal temperature range, determining the range in which the operating temperature is located according to a preset range; wherein the preset range includes a first temperature range, a second temperature range and a third temperature range; the first temperature range is lower than the second temperature range, and the second temperature range is lower than the third temperature range; in response to the operating temperature being within the first temperature range, controlling the closing of the first outlet of the first three-way solenoid valve, opening the first inlet and the second outlet, controlling the opening of the second inlet and the fourth outlet of the first four-way solenoid valve, closing the third inlet and the third outlet, controlling the opening of the seventh inlet and the sixth outlet of the second four-way solenoid valve, closing the sixth inlet and the seventh outlet, controlling the closing of the fourth inlet of the second three-way solenoid valve, opening the fifth inlet and the fifth outlet; in response to the operating temperature Within the second temperature range, the first outlet of the first three-way solenoid valve is controlled to be closed, and the first inlet and the second outlet are opened; the second inlet and the third outlet of the first four-way solenoid valve are controlled to be opened, and the third inlet and the fourth outlet are closed; the sixth inlet and the sixth outlet of the second four-way solenoid valve are controlled to be opened, and the seventh inlet and the seventh outlet are closed; the fourth inlet of the second three-way solenoid valve is controlled to be closed, and the fifth inlet and the fifth outlet are opened; in response to the operating temperature being within the third temperature range, the first outlet of the first three-way solenoid valve is controlled to be closed, and the first inlet and the second outlet are opened; the second inlet and the third outlet of the first four-way solenoid valve are controlled to be opened, and the third inlet and the fourth outlet are closed; the sixth inlet and the seventh outlet of the second four-way solenoid valve are controlled to be opened, and the seventh inlet and the sixth outlet are closed; the fifth inlet of the second three-way solenoid valve is controlled to be closed, and the fourth inlet and the fifth outlet are opened.

[0063] Specifically, when the operating temperature of the target engine point is not within the optimal temperature range, it can indicate that the operating temperature of the target engine point is either too high or too low. In this case, the operating temperature range is determined based on a preset range (a first temperature range, a second temperature range, and a third temperature range). The first temperature range is lower than the second temperature range, and the second temperature range is lower than the third temperature range. In other words, the third temperature range is greater than the second temperature range, which is greater than the first temperature range. The operating temperature of the target engine point is compared with the first temperature range to determine whether the operating temperature of the target engine point is within the first temperature range. If the operating temperature of the target engine point is within the first temperature range, it can indicate that the operating temperature of the target engine point is too low. In this case, the first outlet of the first three-way solenoid valve is controlled to close, and the first and second inlets are opened to prevent coolant from entering the heating pipe, allowing coolant to flow directly into the first cooling pipe. The second and fourth inlets of the first four-way solenoid valve are controlled to open, and the third inlet and third outlet are closed to allow coolant in the first cooling pipe to flow into the first direct flow pipe, preventing coolant in the first cooling pipe from flowing into the second cooling pipe and preventing coolant in the heating pipe from flowing into the first direct flow pipe. The seventh inlet and sixth outlet of the second four-way solenoid valve are controlled to open, and the sixth inlet and seventh outlet are closed, so that the coolant in the first DC pipe flows to the second DC pipe, preventing the coolant in the second cooling pipe from flowing to the second DC pipe and preventing the coolant in the first DC pipe from flowing to the third cooling pipe. The fourth inlet of the second three-way solenoid valve is controlled to close, and the fifth inlet and fifth outlet are opened to prevent the coolant in the third cooling pipe from flowing out of the lower water chamber, so that the coolant in the second DC pipe flows out of the lower water chamber. It can be understood that when the operating temperature of the target engine point is within the first temperature range, the coolant in the upper water chamber flows from the first cooling pipe to the first DC pipe, then from the first DC pipe to the second DC pipe, and finally from the second DC pipe to the lower water chamber.

[0064] The operating temperature of the target engine point is compared with the second temperature range to determine whether the operating temperature of the target engine point is within the second temperature range. If the operating temperature of the target engine point is within the second temperature range, it can be indicated that the operating temperature of the target engine point is high and the engine needs to be cooled. At this time, the first outlet of the first three-way solenoid valve is controlled to be closed, and the first inlet and the second outlet are opened to prevent the coolant in the upper water chamber from flowing to the heating pipe, so that the coolant in the upper water chamber flows directly to the first cooling pipe. The second inlet and the third outlet of the first four-way solenoid valve are controlled to be opened, and the third inlet and the fourth outlet are closed to allow the coolant in the first cooling pipe to flow to the second cooling pipe, preventing the coolant in the first cooling pipe from flowing to the first DC pipe and preventing the coolant in the heating pipe from flowing to the second cooling pipe. The sixth inlet and the sixth outlet of the second four-way solenoid valve are controlled to be opened, and the seventh inlet and the seventh outlet are closed to allow the coolant in the second cooling pipe to flow to the second DC pipe, preventing the coolant in the first DC pipe from flowing to the second DC pipe and preventing the coolant in the second cooling pipe from flowing to the third cooling pipe. The fourth inlet of the second three-way solenoid valve is closed, and the fifth inlet and fifth outlet are opened, preventing the coolant in the third cooling pipe from flowing out of the lower water chamber and allowing the coolant in the second direct flow pipe to flow out of the lower water chamber. This means that when the operating temperature at the target engine point is within the second temperature range, the coolant in the upper water chamber flows from the first cooling pipe to the second cooling pipe, then from the second cooling pipe to the second direct flow pipe, and finally from the second direct flow pipe to the lower water chamber.

[0065] The operating temperature of the target engine point is compared with the third temperature interval to determine whether the operating temperature of the target engine point is within the third temperature interval. If the operating temperature of the target engine point is within the third temperature interval, it can be indicated that the operating temperature of the target engine point is very high and the engine needs to be cooled quickly. At this time, the first outlet of the first three-way solenoid valve is controlled to be closed, and the first inlet and the second outlet are opened to prevent the coolant in the upper water chamber from flowing into the heating pipe, and the coolant in the upper water chamber flows directly into the first cooling pipe. The second inlet and the third outlet of the first four-way solenoid valve are controlled to be opened, and the third inlet and the fourth outlet are closed to allow the coolant in the first cooling pipe to flow into the second cooling pipe, preventing the coolant in the first cooling pipe from flowing into the first direct current pipe and preventing the coolant in the heating pipe from flowing into the second cooling pipe. The sixth inlet and the seventh outlet of the second four-way solenoid valve are controlled to be opened, and the seventh inlet and the sixth outlet are closed to allow the coolant in the second cooling pipe to flow into the third cooling pipe, preventing the coolant in the first direct current pipe from flowing into the third cooling pipe and preventing the coolant in the second cooling pipe from flowing into the second direct current pipe. The fifth inlet of the second three-way solenoid valve is closed, and the fourth inlet and fifth outlet are opened, preventing the coolant in the second direct current pipe from flowing out of the lower water chamber and allowing the coolant in the third cooling pipe to flow out of the lower water chamber. This means that when the operating temperature at the target engine point is within the third temperature range, the coolant in the upper water chamber flows from the first cooling pipe to the second cooling pipe, then from the second cooling pipe to the third cooling pipe, and finally from the third cooling pipe to the lower water chamber.

[0078] In summary, the control method for a coolant temperature control system according to an embodiment of the present invention includes: obtaining the operating temperature of the target engine point and determining whether the operating temperature is within an optimal temperature range; in response to the operating temperature not being within the optimal temperature range, determining whether the operating temperature is above a preset temperature threshold; in response to the operating temperature being above the preset temperature threshold, controlling the closing of the first outlet of a first three-way solenoid valve and the opening of the first inlet and second outlet, and controlling the opening of the second inlet and third outlet of a first four-way solenoid valve and the closing of the third inlet and fourth outlet. Thus, this method can adjust the cooling effect of the temperature control system according to the operating temperature of the target engine point, eliminate the thermostat, and integrate the thermostat's functions into the water tank, thereby reducing the failure rate of the temperature control system, resolving issues such as engine starting difficulties and emissions in winter, and reducing production costs.
