AI Technical Summary

Technical Problem

Existing diesel engine oil-water separators are ineffective at separating emulsified or finely dispersed water, which affects fuel quality and engine stability.

Method used

It adopts a multi-stage filtration and adsorption structure, including baffles, filter plates, cylinder push plates, and adsorption plates. It utilizes the difference in oil and water density to achieve natural stratification, and the oil and water are separated by the cylinder. Combined with the filtration of the filter plates and the adsorption of the adsorption plates, multi-stage separation is achieved.

Benefits of technology

It improves the thoroughness and rate of oil-water separation, ensures fuel quality, avoids the residue of emulsified water, and enhances engine operating stability and fuel quality.
