PROBLEM TO BE SOLVED: To inhibit that quantity of fuel injected at a time of cold start after stopping an engine once is insufficient and that air fuel ratio becomes lean as compared to target air fuel ratio by using learning value of feed back correction quantity of fuel injection quantity obtained when degree of oil dilution by fuel is large. SOLUTION: An engine ECU executes a program including a step (S100) executing degree of oil dilution calculation process, a step (S200) determining whether degree of oil dilution is large or not, and a step (S300) prohibiting store of the learning value when oil dilution is large (YES in S200).
