<p><P>PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of preventing a leakage of particulates and blocking of a DPF by appropriately estimating the amount of particulates collected by the DPF. <P>SOLUTION: Immediately after oil supply, a third DPT map with the largest set value is selected as a map for computing a particulate emission amount DPT per unit time (S14), and the collected particulate amount QPT of the DPF 32 is computed. When the operation frequency N of idling leaning value CETIDL in an idling operation state reaches the predetermined frequency NO, a cetane value leaning value CETLRN is set as the idling learning value CETIDL, and a DPT map corresponding to the cetane value learning value CETLRN is selected (S19, S23, S24). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
