Abstract

Abstract:

To understand the mechanism of the different wettability of surfaces on the spreading behavior and evaporation process of attached oil film， which effectively further improves the problem of wet wall of fuel spray in compression-ignition engines， various wettability experimental surfaces were prepared using a surface wettability modification technique， and the spreading behavior and evaporation process of the oil film of n-butanol droplets after impacting the wall were investigated using laser-induced fluorescence. The results showed that the hydrophilicity of the laser-etched surface was substantially increased， resulting in an increase in the spreading area and a decrease in the spreading thickness of the attached oil film. While the chemically etched surface with low surface energy modification significantly enhances the hydrophobicity properties. Which weakens the droplet spreading ability， thus reducing the spreading area and increasing the spreading thickness. In addition， under the same experimental conditions， the oil film evaporation rate was the fastest on the laser-etched surface， while the evaporation time on the smooth surface and the chemically etched surface was increased sequentially. The present study results support critical data for the optimal design of combustion chamber material surfaces for internal combustion engines.
