Abstract
In an internal combustion engine equipped with an adsorbent for adsorbing unburned fuel components, the amount of unburned fuel components adsorbed to the adsorbent is determined with good precision. The amount of fuel components adhered in a passage that is located upstream of the adsorbent and that conducts fuel components is determined. By taking into consideration the determined amount of adhered fuel components, the amount of fuel components adsorbed to the adsorbent is determined.
