Light Based Fuel Sulfur Sensor and System

摘要

An ultraviolet sensor arrangement detects the amount of sulfur in a fuel of an internal combustion engine by emitting an ultraviolet light field in the presence of the fuel. A detector is disposed to detect a responsive amount of fluorescent light and provide a sensing signal indicative of the amount of sulfur in the fuel. A filter (or filters) receives the sensing signal and provides a filtered sensing signal to a sensing circuit.
