PROBLEM TO BE SOLVED: To maintain an air-fuel ratio for preventing deterioration of an exhaust gas noxious component value and improving operability at the time of starting an engine, in a start time fuel injection control device for the engine. SOLUTION: In the case that correction factor acquisition condition for star time is satisfied at a previous operation of the engine, a control means stores an air-fuel ratio feedback correction factor and an air-fuel ratio learning correction factor and calculates a start-time fuel injection correction factor from the stored air-fuel ratio feedback correction factor and the air-fuel ratio learning correction factor and, at the time of starting the engine, calculates a start time injection quantity by using a start time basic fuel injection quantity and the start-time fuel injection correction factor.
