摘要
汽车的燃油加注管的结构决定了燃油加注过程的顺畅性,设计结构不好的燃油加注管容易引起反喷或提前"跳枪"现象。文章运用CFD软件对某一乘用车燃油加注过程进行模拟分析,获得了不同时刻加注管内油气分布的状态。根据分析结果对加注管结构进行优化,使加注过程更加顺畅,降低了跳枪和反喷的风险,为燃油系统优化设计提供了参考。
The structure of fuel-filling pipe was very important for the smoothness in the fuel filling process,a bad design of oil-filling pipe could cause fuel spilling or injector shut-off.Simulation of fuel-filling base on one vehicle was performed using the CFD software in this paper.The fuel and gas distribution of filling pipe is obtained in this simulation.According the result,then,the design of fuel-filling pipe was improved,the smoothness was better,and decrease fuel spilling risk,providing a basis for optimization design of a fuel-tank system.
