Device and method for adjusting dosage of fuel additive based on in-situ measurement of additive and containment concentration

摘要

A device and method for adjusting dosage of a fuel additive is described. The device includes a fuel reservoir and an additive reservoir. A variable-flow pump is used to pump the additive into contact with the fuel to create a combined fluid. An ESR sensor is positioned downstream from the pump and fuel reservoir such that a portion of the combined fluid passes through the ESR sensor, which measures the concentration of contaminants and fuel additive in the fuel. Based on the concentrations, a controller controls the rate at which the fuel additive is pumped, thereby adjusting the dosage of the fuel additive.
