Technical Field

The invention belongs to the technical field of quantitative extraction of engine oil, and particularly relates to a device and a method for quantitatively extracting engine oil.

Background

The export of engines and the production plants of finished vehicles in China are rising abroad, and the export quantity of the engines is increasing. Before the engine is exported, the whole engine test is carried out in China in order to ensure the quality and consistency, a certain amount of engine oil is added into the tested engines and the tested engines are subjected to a heat test, and the tested engines contain a certain amount of engine oil; at present, all imported engine countries have clear regulations on engine oil carried by the engine (all countries have different standards on the residual amount of the engine oil), and foreign whole vehicle factories also have clear requirements on the residual oil amount of the engine oil of the imported engine so as to ensure the accuracy of secondary refueling.

The existing engine oil discharge mainly comprises two types:

firstly, oil is drained from an oil drain hole of an oil pan, but oil stains are left in the drained oil, and a screw plug gasket of the oil drain hole is a disposable sealing element, so that the cost is wasted in the oil draining process;

secondly, the oil is extracted from the mouth of the oil gauge by a hydraulic pump or a diaphragm pump, and due to the change of oil viscosity caused by the change of oil temperature after the engine hot test, the internal circulation of the engine oil and the special condition of an oil pan, the phenomenon of hollow or non-well pumping in the oil pumping process can be caused, so that the residual oil after the engine pumps cannot be controlled in consistency, and the residual oil cannot be detected and passed in imported state customs and foreign whole factories, thereby causing the delivery period, the cost and the increase of the management cost.
