摘要： 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.

摘要： Methods and systems are provided for operating a fuel vapor recovery system having a fuel tank isolation valve coupled between a fuel tank and a canister. Fuel vapors are purged from the fuel tank to a canister buffer over a plurality of purge pulses. The pulses are adjusted based on the buffer capacity, a purge flow rate, and a fuel tank pressure to improve control of canister loading and reduce air-to-fuel ratio disturbances.
