Automatic gas blowing device for eliminating residual engine oil in engine

Abstract

The invention discloses an automatic gas blowing device for eliminating residual engine oil in an engine. The engine comprises an engine oil adding opening which is provided with an engine oil opening cover. The automatic gas blowing device comprises a compressed gas source, a connector and a controller. The connector comprises a cover-shaped piece used for being arranged on the engine oil adding opening in a covering manner;a first connector penetrates the end face of the cover-shaped piece, and a second connector is connected with the first connector through a gas pipe. The second connector is used for being communicated with the compressed gas source. The controller comprises a timekeeper and an electromagnetic valve. The electromagnetic valve is used for controlling the second connector to be connected or disconnected with the compressed gas source. The timekeeper controls the opening and closing time of the electromagnetic valve. By means of the automatic gas blowing device, the production cost of an engine factory can be reduced, the potential hazard that an automobile factory is stained by residual engine oil when new engine oil is added can be prevented, and the quality of the new engine oil can be ensured.

Description

technical field [0001] The invention relates to the technical field, in particular to an automatic air blowing device for removing residual engine oil inside an engine. Background technique [0002] During the production process of the engine, engine oil must be added for performance adjustment. However, in order to reduce the manufacturing cost, the engine oil used for engine performance adjustment is recycled and filtered oil that has been reused many times. The reused engine oil appears darker than new engine oil. Before the engine leaves the factory, the oil used for performance debugging needs to be released. However, due to factors such as the viscosity of the engine oil, the complexity of the oil passage in the engine cavity, the different assembly positions of the oil drain plug, and the engine hanging by the suspension chain is not in a horizontal position. It is impossible to completely drain the engine oil in the engine cavity, and a certain amount of engine oil w...

Problems solved by technology

[0002] During the production process of the engine, engine oil must be added for performance adjustment, but in order to reduce manufacturing costs, the engine oil used for engine performance adjustment is recycled and filtered oil that has been reused many times, and the reused engine oil appears darker than new engine oil

Before the engine leaves the factory, the oil used for performance debugging needs to be released. However, due to factors such as the viscosity of the engine oil, the complexity of the oil passage in the engine cavity, the different assembly positions of the oil drain plug, and the engine hanging by the suspension chain is not in a horizontal position. It is impossible to completely drain the engine oil in the engine cavity, and a certain amount of engine oil will remain in the engine and be taken out of the factory

[0003] Nowadays, the natural discharge method is generally used, but the residual oil in the engine body cannot be drained cleanly. If there is too much residual oil in the engine belt, it will not only cause waste of oil and increase manufacturing costs, but also cause problems with the new oil added by the car factory. Mixed use will make the new engine oil black and affect the quality of the new engine oil
