<P>PROBLEM TO BE SOLVED: To provide an oil supply system of an internal combustion engine which can inhibit deterioration of durability in an exhaust emission control device due to generation of a phenomenon of misfire. <P>SOLUTION: The system includes: an oil supply passage which supplies oil force-fed by an oil pump to components of the internal combustion engine; an oil jet which communicates to the oil supply passage to jet oil in the same supply passage toward a piston of the internal combustion engine; and the exhaust emission control device which is provided in an exhaust passage of the internal combustion engine to purify exhaust gas. Through operation control of a pressure modification device, when the internal combustion engine generates the phenomenon of misfire in (S101: YES), compared with the case where no phenomenon of misfire occurs (S101: NO), pressure of the oil in the oil supply passage is set to high pressure (S103). <P>COPYRIGHT: (C)2013,JPO&INPIT |
