In the embodiment of the application, through being provided with radiator 1, retarber 2, first solenoid valve 3, second solenoid valve 4, engine 5, thermostat 6, water pump 7 and engine electronic control unit 8's retarber cooling system, first solenoid valve 3 and second solenoid valve 4 are used for controlling the inflow that gets into retarber 2, when detecting retarber 2 and need cool off, engine electronic control unit 8 is used for controlling the aperture of first solenoid valve 3 and second solenoid valve 4's valve, wherein, the temperature that gets into retarber 2 and intake can be adjusted through the aperture of adjusting first solenoid valve 3 and second solenoid valve 4, ensure that retarber 2 is in optimum machine oil temperature, thereby avoid appearing the problem of cold car excessive wear because of retarber 2 is not lubricated, the life of whole car retarber has been promoted.
Optionally, in the process of system operation, in order to judge whether the retarder 2 needs to be cooled, the temperature of cooling water passing through the engine 5 and the temperature of engine oil of the retarder 2 need to be sensed in real time, and whether the retarder 2 reaches the condition of needing cooling is judged according to the temperature of the cooling water and the temperature of the engine oil of the retarder 2. Therefore, the cooling system further needs to be provided with a water temperature sensor 9, an oil temperature sensor 10 and a retarder determination module 11, wherein the water temperature sensor 9 is arranged between the thermostat 6 and the retarder 2, the oil temperature sensor 10 is arranged on the retarder 2, and the retarder determination module 11 is arranged on the retarder 2.
After the retarder judgment module 11 judges whether the retarder 2 reaches the condition of cooling requirement according to the oil temperature sensed by the oil temperature sensor 10 and the water temperature sensed by the water temperature sensor 9, an electric signal capable of displaying the result is sent to the engine electronic control unit 8 according to the generated judgment result, so that the engine electronic control unit 8 adjusts the first electromagnetic valve 3 and the second electromagnetic valve 4 according to the electric signal.

In the embodiment of the present application, the process of cooling the water temperature is substantially divided into two processes, one is a data acquisition process and one is a control process. In the data acquisition process, the temperature of the cooling water flowing through the water temperature sensor 9 of the engine 5 is acquired, and the value is transmitted to the electronic engine control unit 8.

In the thermal cycle, as the temperature of the cooling water of the engine 5 rises, the thermostat 6 is opened, the small cycle is closed, and the electronic control unit 8 of the engine controls the opening degrees of the two electromagnetic valves of the first electromagnetic valve 3 or the second electromagnetic valve 4 according to the actual cooling water requirement of the retarder 2 corresponding to the temperature sensed by the oil temperature sensor 10 and the temperature acquired by the water temperature sensor 9, so that the temperature of the inlet water entering the retarder 2 is adjusted. The retarder judgment module 11 can judge whether the retarder 2 needs to be cooled in the thermal cycle process, and if the retarder 2 does not need to be cooled, the engine electronic control unit 8 controls the two electromagnetic valves of the first electromagnetic valve 3 and the second electromagnetic valve 4 to be closed according to temperature readings sensed by the oil temperature sensor 10 and the water temperature sensor 9; if cooling is needed, whether the water temperature of the cooling water passing through the engine 5 is higher than a certain preset value or not can be determined through the water temperature readings sensed by the water temperature sensor 9, if the water temperature is higher than the certain preset value, the water temperature of the cooling water passing through the engine 5 is determined to be too high, at the moment, the electronic control unit 8 of the engine can determine the closing of the first electromagnetic valve 3 and the opening degree of the second electromagnetic valve 4 according to the temperature readings sensed by the oil temperature sensor 10 and the water temperature sensor 9, so that the water inlet temperature of the retarder 2 is adjusted, and the retarder 2 is ensured to be at the optimum engine oil temperature. Furthermore, the electronic control unit 8 of the engine can adjust the cooling system of the engine to dissipate heat of the cooling water according to the temperature of the cooling water collected by the water temperature sensor 9, so that the engine is ensured to be at the optimum water temperature.
If the temperature is not higher than a certain preset value, the water temperature of the cooling water passing through the engine 5 is determined to be not high, at the moment, the electronic control unit 8 of the engine can determine that the first electromagnetic valve 3 is opened and the second electromagnetic valve 4 is closed according to temperature readings sensed by the oil temperature sensor 10 and the water temperature sensor 9. The cooling water is cooled by the retarder 2 and then cooled by the radiator 1, and finally circulates again before returning to the water pump 7.
In the embodiment of the present application, in addition to cooling the retarder 2 under a certain condition, the trigger condition for cooling the buffer 2 can be further optimized by further integrating the cooling water state of the engine 5, so that the cooling efficiency of the retarder 2 is improved.
