摘要： Embodiments for controlling fuel vapors are disclosed. In one example, a method comprises during a purge of a fuel vapor canister, adjusting a heater of the fuel vapor canister based on a rate of a purge flow exiting the fuel vapor canister and a concentration of hydrocarbons released from the fuel vapor canister. In this way, a fuel vapor canister purge efficiency may be increased.

摘要翻译： 公开了用于控制燃料蒸气的实施例。 在一个示例中，一种方法包括在吹扫燃料蒸气罐的同时，基于从燃料蒸气罐排出的吹扫流的速率和从燃料蒸气罐释放的烃的浓度来调节燃料蒸汽罐的加热器。 以这种方式，可以增加燃料蒸汽罐吹扫效率。

摘要： Methods and systems are provided for purging a multi-port canister into an engine intake. Air is circulated through the canister and a resulting purge air is directed to an intake passage upstream of a throttle in engine configured with a throttle body. An amount of fresh intake air received at the intake passage is corresponding decreased.
