Abstract
A purge valve and a fuel vapor management system for use with an engine emission control system are disclosed. The purge valve may include a first inlet for receiving a first flow of air from an air cleaner, a second inlet for receiving a second flow of purge vapors from an evaporative canister, and an outlet directing a controlled mixture of the first and second flows to an engine, upstream of an intake throttle. Relative amounts of the first flow and second flow may be selectively controlled by varying a position of the valve.
