Abstract
A reducing agent metering system for delivering reducing agent to a lean burn internal combustion engine. The reducing agent metering system includes a metering system housing, a system for metering vaporized reducing agent to the internal combustion engine, the system positioned within the metering system housing and a system for delivering an atomized stream of liquid reducing agent to the lean burn internal combustion engine, the system positioned within the metering system housing, wherein the reducing agent metering system is operable to transition from metering vaporized reducing agent to delivering an atomized stream of liquid reducing agent to the lean burn internal combustion engine.
