<P>PROBLEM TO BE SOLVED: To improve fuel economy by restraining a fuel increase quantity for reducing the exhaust temperature. <P>SOLUTION: This control device has a supercharger 13 for supercharging intake air, an intake flow control valve 21 arranged in an intake passage 16 and imparting a flow component to the intake air flowing in a combustion chamber, and an exhaust temperature sensor 27 detecting the actual exhaust temperature. When this actual exhaust temperature is the predetermined exhaust temperature or more, the intake flow control valve 21 is closed, and the exhaust temperature is lowered by strengthening the flow component to the intake air flowing in the combustion chamber. <P>COPYRIGHT: (C)2007,JPO&INPIT |
