Abstract

An ignition timing control device for an internal combustion engine includes a retarding portion and a prohibiting portion. The retarding portion retards ignition timing according to a parameter that correlates with temperature inside a combustion chamber. The prohibiting portion prohibits the retarding portion from retarding the ignition timing when alcohol concentration in blended fuel is greater than or equal to a predetermined value. The internal combustion engine uses the blended fuel in which an alcohol fuel and a gasoline fuel are blended at arbitrary proportion.
