Abstract
A carbon canister adapted for use in an automotive vehicle is disclosed. The system has a carbon canister housing defining a cavity adapted for holding carbon pellets with the housing including: a port and a strainer disposed between the port and the cavity with a portion of a surface of the strainer being convex with respect to the cavity wherein the strainer has a plurality of orifices. The integral strainer obviates the need for a foam filter to prevent the carbon pellets from escaping from the carbon canister housing through the port. In some applications, the carbon canister system has three ports: one to the engine, one to atmosphere, and one to a vent of the fuel tank, each having a strainer disposed in the port.
