In the traditional engine lubrication system function test mechanism, the oil pressure in the main oil gallery cannot be adjusted greatly, and when the oil pressure in the main oil gallery does not meet the design requirement, the flow target of design optimization of the oil pump cannot be determined.
In order to solve the above problems, the present invention provides a function test mechanism for an engine lubrication system, as shown in fig. 1, the function test mechanism for an engine lubrication system at least includes components such as an engine oil pan 1, a process oil tank 2, a main oil pipeline 3, and a process oil pipeline 4.

The main oil pump 13, the check valve 32, the oil cooler 33, the filter 34, and the main oil gallery flow meter 35 are sequentially disposed in the main oil pipe 3.
The engine oil in the engine oil pan 1 flows into each passage inside the engine through the main oil pipe 3 by driving of the main oil pump 13. In the test process, the flow value in the main oil pipeline 3 is obtained through the main oil passage flowmeter 35, so that the performance test of the main engine oil pump 13 under different flow rates is realized, and the optimal design of the main engine oil pump 13 is realized.

When the oil pressure in the main oil pipeline 3 cannot meet the preset design requirement, the process oil pump 41 drives the engine oil in the process oil tank 2 to flow into the main oil pipeline 3, so that the flow in the main oil pipeline 3 is increased, the oil pressure in the main oil pipeline 3 finally meets the preset design requirement, and the flow target of the design optimization of the main oil pump 13 is determined.
Therefore, the engine lubrication system function test mechanism provided by the invention is provided with the process engine oil tank and the process engine oil pipeline communicated with the process engine oil tank and the main oil pipeline. When the oil pressure of the main oil pipeline is insufficient, the oil pipeline of the process engine can supplement oil to the main oil pipeline, so that the oil pressure of the main oil channel meets the design requirement, and finally the flow target of the design optimization of the engine oil pump is determined.
Optionally, the process oil pump 41 is a displacement type oil pump with adjustable flow, and the process oil pump 41 is controlled by a servo motor. Through the control of the servo motor, the process oil pump 41 can flexibly control the flow in the process oil pipeline 4, thereby ensuring that the oil pressure of the main oil gallery is increased to a preset value.

When the oil pressure in the main oil conduit 3 is too high, the relief valve 61 is opened, and part of the engine oil in the main oil conduit 3 flows back to the engine oil pan 1 through the relief pipeline 6, so that the pressure relief is realized.
With reference to fig. 1, optionally, the engine lubrication system function testing mechanism in the present invention further includes a bypass pipeline 7, an oil inlet end of the bypass pipeline 7 is connected to the main oil pipeline 3 between the check valve 32 and the oil cooler 33, an oil outlet end of the bypass pipeline 7 is connected to an oil inlet of the filter 34, and the bypass pipeline 7 is provided with a bypass valve 71.
