Research on the influence of fuel detergent synergist on engine fuel supply system

Abstract

This paper selects 6 gasoline detergent synergists and 6 diesel detergent synergists that are mainstream in the market. 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 were studied,and these changes are compared with the benchmark fuel. 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 reference fuel, but some gasoline detergent synergists have a slight corrosive swelling effect on the gasoline fuel supply system.
