ABSTRACT:
A safe, reliable system for automatically dosing diesel truck fuel tanks with a fuel additive is provided. The additive, such as a concentrated solution containing fuel borne catalyst (FBC), is fed by positive feed means in pulsed doses while the engine is on. The frequency and amount of FBC injection is controlled as a function of the time the engine is operated and predetermined values for rate of fuel consumption and intended additive concentrations in the fuel.
