<P>PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine preventing deterioration such as a lowering in the performance of the internal combustion engine at the time of executing a purge processing, in a multiple cylinder internal combustion engine sharing injection fuel with a first fuel injection means to inject fuel to the inside of a cylinder and a second fuel injection means to inject fuel to an intake passage. <P>SOLUTION: When a direct injection ratio is not 1 (NO in S430) at the time of purge execution (YES in S400), an engine ECU executes a program including a step (S460) of determining whether or not a ratio of a purge correction amount fpg × maximum purge variation PGERR to a PFI basic injection amount taupb is at a constant α or more, and a step (S480) of calculating a purge correction amount fpgd on a cylinder injection injector side and a purge correction amount fpgp on an intake passage injection injector side so that when the ratio is at the constant α or more (YES in S460), the purge correction amount in the intake passage injection injector is strictly limited if its sharing ratio is smaller and an insufficient amount is purged and compensated by using the cylinder injection injector. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
