Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of engine oil temperature control, and more specifically, to a method for controlling engine temperature in an engine oil delivery system. Background Art
[0002] As a traditional power engine, the heat energy generated by the combustion of its fuel is used for work, part of which is discharged into the atmosphere through exhaust, part of which is transferred through coolant and dissipated through the vehicle's cooling system, and part of which is lost by overcoming the engine's own friction. Therefore, reducing engine friction loss is the most important means to reduce friction loss and improve the fuel economy of the whole vehicle. The National VI emission test needs to be started when the engine is cold. At this time, the post-treatment temperature, water temperature, and oil temperature are required to be less than 30°C. At present, research and development institutions and certification centers use natural cooling methods to cool the engine. This cooling method takes at least 10 hours. Even if forced cooling is used, it only uses cold air to blow the engine, and the cooling time takes about 5 hours, which causes a significant decrease in the utilization rate of the test equipment.
[0003] Therefore, it is necessary to provide a method for controlling the engine temperature in an oil delivery system to solve the above problems. Summary of the invention

[0023] A coolant inlet 20 is fixedly installed at the side end of the coolant outlet 19 , a front end pipeline of the coolant inlet 20 is connected with a liquid inlet pipe, and a front end of the liquid inlet pipe is fixedly connected to the upper end of the secondary exchanger 15 .
[0024] An oil inlet 8 is fixedly installed at the upper end of the coolant inlet 20 , a front end pipeline of the oil inlet 8 is connected to an oil inlet pipe 11 , and an oil filter element 21 is fixedly installed at the pipe mouth of the oil inlet pipe 11 .
[0025] The front end of the oil inlet pipe 11 is connected to the oil pump 10 . The upper end of the oil pump 10 is fixedly mounted with an oil inlet pipe 2 . The front end of the oil inlet pipe 2 is fixedly connected to the lower end of the secondary exchanger 15 .
[0026] The upper end of the oil inlet 8 is fixedly installed with the oil outlet 4, the front end of the oil outlet 4 is fixedly installed with the oil outlet pipe 13, the front end of the oil outlet pipe 13 is fixedly connected to the upper end of the secondary exchanger 15, the lower end of the oil outlet pipe 13 is fixedly installed with a valve port, the lower end of the valve port is fixedly connected to the pipeline of the oil inlet pipe 11, and the front end flange of the oil inlet 8 is connected to the oil guide pipe 9.
[0027] The temperature detection component includes an oil delivery port 3, which is fixedly installed on the upper end of the oil tank 2. The bottom side end of the oil tank 2 is fixedly connected with an oil leakage port 6, the side end of the oil delivery port 3 is fixedly installed with an oil circuit controller 5, and the bottom front of the oil tank 2 is fixedly installed with a temperature detection head 7.
[0028] A controller cavity 16 is provided inside the oil circuit controller 5 , an oil leakage pipe 17 is fixedly connected to the front end of the oil leakage port 6 , the lower end of the oil delivery port 3 is connected to the oil leakage pipe 17 , and a branch of the oil leakage pipe 17 is connected to the oil circuit controller 5 .
[0029] The method for controlling the engine temperature in the oil delivery system is characterized by comprising the following steps: Step 1: The oil pump draws out the oil from the oil tank, guides the oil into the oil inlet pipe through the oil guide pipe, and then transmits it to the secondary exchanger through the oil inlet pipe. After the oil is input into the secondary exchanger, it is input into the oil outlet through the oil outlet pipe and then input into the engine through the oil outlet.
[0030] Step 2: The coolant will be input into the liquid outlet pipe through the secondary exchanger, and then input into the two-way regulating valve through the liquid outlet pipe. The two-way regulating valve uses the temperature controller to continuously compare the detection value of the temperature sensor with the set value and continuously output signals.
[0031] Specifically, the staff starts the oil pump 10 to extract the oil in the oil tank 2, guides the oil into the oil inlet pipe 11 through the oil guide pipe 9, and then transmits the oil to the secondary exchanger 15 through the oil inlet pipe 11. The secondary exchanger 15 dissipates the heat of the input oil. After the oil is input into the secondary exchanger 15, it is input into the oil outlet 4 through the oil outlet pipe 13 and then input into the engine through the oil outlet 4. When the engine is used for a long time, the temperature of the oil is still too high. At this time, the staff will input the coolant into the liquid inlet pipe through the coolant inlet 20, and then enter the secondary exchanger 15 through the liquid inlet pipe to cool the oil again to prevent the oil temperature from being too high and causing the oil consumption to increase, and at the same time prevent the oil from being oxidized and deteriorated, thereby affecting the lubrication effect of the engine. The coolant will be input into the liquid outlet pipe 12 through the secondary exchanger 15, and then input into the two-way regulating valve 14 through the liquid outlet pipe 12. The two-way regulating valve 14 uses a temperature controller to continuously compare the detection value of the temperature sensor with the set value. Before the engine oil is input into the secondary exchanger 7, the oil filter element 21 at the front end of the oil inlet pipe 11 will filter the engine oil to prevent metal chips and combustion residues, such as soot and dirt, from entering the hydraulic system with friction or solid particles in the engine oil formed due to aging from entering the secondary exchanger 15 and the oil pump 10, thereby reducing the wear of parts, keeping the engine oil clean, and extending the service life of the engine.
[0032] After the engine oil is input into the secondary exchanger 7, it is transmitted to the oil outlet 4 through the oil outlet pipe 13, and then input into the engine through the oil outlet 4. When the engine is used for too long, the temperature of the engine oil is still too high. At this time, the staff will input the coolant through the coolant inlet 20, input it into the liquid inlet pipe, and then enter the secondary exchanger 7 through the liquid inlet pipe to cool and dissipate the heat of the engine oil again. The cooling hydraulic pressure and oil pressure can be observed on the operation panel 18 to prevent the oil pressure cooling hydraulic pressure from being too high and affecting the engine life. The coolant will be input into the liquid outlet pipe 12 through the secondary exchanger 15, and then input into the two-way regulating valve 14 through the liquid outlet pipe 12. The two-way regulating valve 14 uses a temperature controller to continuously compare the detection value of the temperature sensor with the set value, and continuously outputs a signal. The opening connection of the two-way regulating valve 14 is adjustable, and ultimately the ambient temperature measured by the temperature sensor is maintained within the set temperature range. Finally, it flows into the engine through the coolant outlet 19 to achieve temperature regulation.
[0033] During the process of the two-way regulating valve 14 detecting the temperature, the temperature detection head 7 on the front of the oil tank 2 will detect the temperature inside the oil tank 2 to see whether the temperature of the oil tank 2 exceeds the temperature that the oil tank 2 can withstand, and then input new oil into the oil circuit controller 5 through the oil delivery port 3, and the newly added engine oil flows into the controller cavity 16 through the oil circuit controller 5. When the temperature of the oil in the oil tank 2 exceeds the temperature set by the program, the oil is cooled at this time, and the oil pump 10 operates normally to extract the oil in the oil tank 2, and the new engine oil will flow into the oil tank 2 through the oil leakage pipe 17, so as to ensure that the oil in the oil tank 2 is always qualified, and also ensure that the oil pump 10 is not easily damaged and can operate stably for a long time. Finally, when the device is not in use, the oil in the oil tank 2 can be emptied through the oil leakage port 6 to avoid oil leakage in the oil tank 2.
