Various systems and methods for an engine in a vehicle which includes an airflow generating device coupled between an alternator and a fuel vapor canister are described. In one example, airflow from the airflow generating device is directed to cool the alternator during a first mode such as when the alternator temperature is greater than a threshold temperature. During a second mode when the alternator temperature is less than the threshold temperature and the engine is boosted, for example, the airflow from the airflow generating device is directed to assist purging of fuel vapors from the fuel vapor canister.
