摘要 选取了市场主流的6种汽油清净增效剂和6种柴油清净增效剂,研究了发动机供油系统主要零部件在含清净增效剂的燃油中浸泡28 d后的质量、体积、硬度、尺寸及表面形貌的变化,并与在基准燃油中浸泡的结果进行对比,以此提出了一种评价燃油清净增效剂对发动机供油系统影响的方法。试验结果表明,多数燃油清净增效剂对发动机供油系统零部件几乎无腐蚀影响或与基准燃油接近,部分清净增效剂对燃油供给系统略微有腐蚀溶胀影响。 Six gasoline detergent synergists and six diesel detergent synergists that are mainstream in the market are selected to study the changes in mass, volume, hardness, size and surface morphology of the main components of the engine fuel supply system after being immersed in fuel containing detergent synergists for 28 days. The results are compared with the results of immersion in the benchmark fuel. A method for evaluating the influence of fuel detergent synergist on engine fuel supply system is proposed. The results show that most of the fuel detergent synergists have almost no corrosive effect on the engine fuel supply system components or are close to the benchmark fuel, but some detergent synergists have a slight corrosive swelling effect on the fuel supply system.
