<P>PROBLEM TO BE SOLVED: To strike a balance between prevention of generation of abnormal combustion at low speed revolution and prevention of decrease in power performance at high speed revolution, regardless of whether an intake air temperature is high or low, in a control device of an internal combustion engine with a supercharger. <P>SOLUTION: The device includes a turbocharger 20 that supercharges intake air. A supercharging pressure is controlled so that an in-cylinder temperature during the compression stroke is substantially constant with respect to a change of the intake air temperature when an engine speed NE is a predetermined value NEt or lower. Meanwhile, the supercharging pressure is controlled so that an in-cylinder filling air amount is substantially constant with respect to the change of the intake air temperature when the engine speed NE is higher than the predetermined value NEt. <P>COPYRIGHT: (C)2012,JPO&INPIT |
