氧化石墨烯对正己醇/柴油混合燃料喷雾与燃烧特性的影响
Influences of Graphene Oxide on the Spray and Combustion Characteristics of n-Hexanol/Diesel Blended Fuel
摘要
Abstract
The effects of adding different contents of graphene oxide on the spray and combustion performance of n-hexanol/diesel blended fuels were studied under different injection pressures.After adding n-hexanol to diesel at a volume fraction of 20%to configure the liquid component,graphene oxide with mass fractions of 20×10-6、40×10-6 and 60×10-6 was added to it respectively to obtain three kinds of blended fuels.The results indicate that the blended fuels exhibit optimal atomization performance at an injection pressure of 160 MPa.Among them,the fuel containing 40×10-6 mass fraction of graphene oxide demonstrates the farthest spray penetration distance,the largest spray angle,and the largest spray area.Furthermore,an appropriate increase in the graphene oxide content enhances the efficiency of fuel-air mixing,improves combustion efficiency,and reduces soot formation.Under the same injection pressure,the fuel with 40×10-6 mass fraction of graphene oxide exhibits the best emission reduction performance and the longest flame lift-off length.关键词
