Abstract
A other-type fuel contamination determination apparatus for an internal combustion engine includes an exhaust gas sensor. The exhaust gas sensor is configured for obtaining one of (a) an air-fuel ratio and (b) a combustion state for the internal combustion engine based on exhaust gas. The other-type fuel contamination determination apparatus determines whether other-type fuel contaminates fuel that is supplied to the internal combustion engine based on an output by the exhaust gas sensor.
