To improve startability when low evaporation characteristic fuel is used.
The control device (electronic control device 1) for the internal combustion engine for performing combustion operation by ignition operation with respect to fuel F supplied to inside of a combustion chamber CC is provided with an engine start control means for increasing intake air amount to inside of the combustion chamber CC at start of the engine as the evaporation characteristics of the fuel F inside the combustion chamber CC are worse. The engine start control means is constituted to increase the intake air amount by performing at least one of reduction control of cranking frequency, valve opening control of a throttle valve 24, or valve opening time expansion control or lift amount increase control of an intake valve 31.
