Abstract
A method, apparatus, and fuel composition for the protection of a catalytic after treatment system and a method for protecting a catalytic after treatment system in a lean burn system are disclosed. A scavenging agent is introduced into the combustion chamber in an amount effective to complex with catalytic poisoning combustion byproducts and improve emissions system durability. In a preferred embodiment, the scavenger is an organometallic compound which also imparts additional desirable properties to the fuel.
