<p><P>PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine that properly operates an engine after refueling. <P>SOLUTION: The device specifies a cetane value region to which a cetane value of fuel supplied to the internal combustion engine belongs, and executes fuel injection control in a first execution mode corresponding to the specified cetane value region. When it is determined that refueling to a fuel tank is performed (t11, t12, t13, and t14), the device executes the fuel injection control in a second execution mode corresponding to a low cetane value region, for an execution period immediately after the refueling, without depending on the specified cetane value region. When a state where a high cetane value region is specified for a period when the refueling is repeated by a frequency of determination is continued (t15), the device inhibits the execution of the fuel injection control in the second execution mode in the execution period to execute the fuel injection control in the first execution mode. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
