<P>PROBLEM TO BE SOLVED: To burn deposit fuel while avoiding occurrence of knocking and suppressing discharge of smoke, in an internal combustion engine with both port injection and in-cylinder injection performed. <P>SOLUTION: This control device (1) for the internal combustion engine controlling the internal combustion engine provided with a supercharger (22 or the like) includes: a first fuel injection means (11d) injecting a first predetermined amount of fuel into a cylinder; a second fuel injection means (11p) injecting a second predetermined amount of fuel into an intake passage; an ignition means (13) performing ignition at a predetermined ignition timing; and a control means (30) which, when raising temperature of the injection port of the first fuel injection means, controls at least one of the first fuel injection means and the second fuel injection means so that the first rate of the first predetermined amount to the total amount of fuel injected and the second rate of the second predetermined amount to the total amount of fuel injected are changed based on supercharging pressure by the supercharger, and also controls the ignition means to change the predetermined ignition timing based on the supercharging pressure, the first rate, and the second rate. <P>COPYRIGHT: (C)2009,JPO&INPIT |
