    摘要： An object of the invention is to provide a control device for an internal combustion engine that regularly and forcefully removes deposit that is accumulated in cylinders and restrains consecutive occurrences of pre-ignition beforehand. The internal combustion engine has a low-speed pre-ignition region in which a possibility of occurrence of pre-ignition increases, in a low-rotation and high-load region. Ignition means (16) for igniting an air-fuel mixture taken into the cylinders is included. When an operation region is in a region other than the low-speed pre-ignition region and in a forceful knock enabling region with a load equivalent to or higher than a lower limit load at which knocking can be forcefully generated by advance of ignition timing, the ignition timing by the ignition means is forcefully advanced at a predetermined control interval, and a maximum in-cylinder pressure that is higher than at a time of ordinary combustion in the operation region and is lower than at a time of occurrence of pre-ignition is generated. The control interval is made longer as a load of the operation region is higher, and the control interval is made shorter as the load of the operation region is lower.

    摘要： An internal combustion engine according to the present invention includes an exhaust treatment device provided in an exhaust passage and a burner device provided upstream of the exhaust treatment device to raise exhaust temperature. The burner device includes a fuel addition valve configured to add fuel into the exhaust passage, a first ignition device configured to ignite the added fuel, a burner catalyst provided downstream of the first ignition device, and a second ignition device provided downstream of the burner catalyst. The burner catalyst partitions the exhaust passage into an infra-catalyst passage formed inside the burner catalyst and an extra-catalyst passage formed outside the burner catalyst. The second ignition means is positioned between the extra-catalyst passage and the exhaust treatment device. Generated soot can be combusted by the second ignition device.
