ENGINE-ON PULSED FUEL ADDITIVE CONCENTRATE DOSING SYSTEM AND CONTROLLER

摘要

A safe, reliable system for automatically dosing diesel truck fuel tanks with a fuel additive is provided. The additive (14), such as a concentrated solution containing fuel borne catalyst (FBC), is fed by a positive feed means (18) 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.
