AI Technical Summary

Technical Problem

Existing oil pans with filler caps cannot effectively trap residues in the engine oil, causing residues to settle at the bottom of the oil pan, affecting oil change operations. Furthermore, when the oil pan is tilted or bumped, oil can easily flow back into the intake manifold, resulting in waste and engine malfunction.

Method used

An oil pan with a filter plate and an opening and closing assembly was designed. The oil filling pipe is equipped with a filter plate and a movable groove. Through the cooperation of the movable block and the orifice plate, the oil is filtered and sealed by the force of the spring and the push rod to prevent residue from clogging. At the same time, the rotating rod drives the elastic wiping plate to clean the residue on the surface of the filter plate.

Benefits of technology

It improves the precision and efficiency of oil filtration, prevents residue blockage, avoids oil spillage and backflow, and ensures the normal operation of the engine.
