Abstract
A fuel dosing system to provide a controlled level of cereum additive from an additive tank either within or external to a diesel powered vehicle's fuel storage tank. The present invention maintains a concentration of cerium that is optimized to assure proper regeneration of a particulate trap used to control particulate emissions from the vehicle's exhaust. The present invention determines the additive dosage required by monitoring the fuel added to the tank during refueling of the vehicle and responds with a proper dose of an optimized amount of additive. The present invention is self contained and imposes a minimum encroachment on the vehicle fuel and electrical system and may also provide appropriate alarm signals to warn of additive depletion and other possible malfunctions.
