<p><P>PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine that can remove a deposit adhering to the inside of a compressor without providing another member. <P>SOLUTION: The control device of an engine 1 includes a low pressure EGR system 78 for refluxing part of exhaust gas to the first intake passage 60 through an EGR passage 79, a blow-by gas reflux route 74 for refluxing blow-by gas to the first intake passage 60 through an EGR passage 34, and the compressor 65 for compressing a mixed gas containing the exhaust gas refluxed from the low pressure EGR system 78 and the blow-by gas refluxed from the blow-by gas reflux route 74, and supplying it to a combustion chamber 7. The control device further includes a temperature control part for controlling the temperature of the mixed gas sucked into the compressor 65, a compression efficiency determination part for determining the efficiency of compression by the compressor 65, and a controller for decreasing the temperature of the mixed gas sucked into the compressor 65 on condition that the compression efficiency of the compressor 65 is a predetermined value or less. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
