ABSTRACT:
A canister purge valve, and an emission control system, for regulating a fuel vapor flow between a fuel vapor collection canister and an intake manifold of an intake manifold of an internal combustion engine. The canister purge valve includes a body having a passage extending between a first port and a second port, a seat defining a portion of the passage, a member movable with respect to the seat, and an actuator that moves the member. The first port of the body is adapted to be in fluid communication with the fuel vapor collection canister, and the second port of the body is adapted to be in fluid communication with the intake manifold of the internal combustion engine. The member moves generally along an axis between a first configuration that prohibits fuel vapor flow through the seat and a second configuration that permits fuel vapor flow through the seat. And the actuator includes a piezo-electric element that moves the member from the first configuration to the second configuration.
