Abstract
A system for monitoring fuel additives on board a vehicle includes a fuel line carrying fuel from a fuel source to an engine; a fuel additive sensor configured to measure concentration of additives in fuel at a point along the fuel line; a fuel additive dispenser connected in parallel to the fuel line; at least one flow control device for controlling an amount of flow from the fuel line into the fuel additive dispenser; and a controller configured to receive input from the fuel additive sensor and to control the flow control device to adjust the amount of the flow from the fuel line into the fuel additive dispenser.

A method for monitoring fuel additives on board a vehicle, comprising:
- flowing fuel from a fuel tank along a fuel line to an engine;
- sensing concentration of additives in the fuel at a point along the fuel line;
- determining whether the concentration of the additive in the fuel is less than a fuel additive specification;
- when the concentration is less than the specification, operating a flow control device to divert a portion of the fuel from the fuel line along a parallel line to a fuel additive dispenser.
