Abstract
An absorbent, such as, for example, an active carbon, is provided in an intake air passage, for example, in an air cleaner, to efficiently adsorb fuel vapor. To ensure that fuel vapor adsorbed into the intake air passage can be efficiently desorbed even when there is only a small amount of the intake air, an intake throttle valve is provided upstream of the adsorbent and an opening of the intake throttle valve is throttled so as to decompress an area near the adsorbent. Desorption of fuel vapor also can be efficiently promoted by using a heater to directly heat the adsorbent in the intake air passage or by heating the intake air to indirectly heat the adsorbent.
