ABSTRACT:
A method is described for identifying fuel composition from an index ratio of oxygen sensors upstream and downstream of a catalyst of the engine. Different index ratios are achieved for different fuel compositions, and thus it is possible to identify fuel composition, such as fuel alcohol content, based on changes in the index ratio.
