<P>PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of suitably restraining oil leakage into an intake passage from a supercharger. <P>SOLUTION: A compressor impeller and a throttle valve of the supercharger are arranged in order from the upstream side in the intake passage of the internal combustion engine. An oil supply device for supplying oil in a housing of the supercharger is installed in the internal combustion engine. A rotary shaft of the compressor impeller is rotatably supported in the housing, and a seal member for sealing the oil leakage to the intake passage via a clearance is arranged in the clearance between the rotary shaft and an inner surface of the housing. When throttle downstream pressure PA1 is lower than first determining pressure J1 and throttle upstream pressure PA2 is lower than second determining pressure J2 (S11: YES, and S12: YES), the pressure of the oil supplied in the housing of the supercharger is reduced by the oil supply device (S14) as compared with the case that the pressure is not so lowered (S11: NO, or S12: NO). <P>COPYRIGHT: (C)2013,JPO&INPIT |
