<P>PROBLEM TO BE SOLVED: To prevent the occurrence of a trouble when performing purge processing of fuel vapor gas in an internal combustion engine equipped with injectors for cylinder injection and for intake passage injection. <P>SOLUTION: An engine ECU 300 executes a program including a step (S410) for calculating an injection sharing ratio (DI ratio) r and a step (S420) for calculating basic injection amounts of injectors for cylinder injection and for intake passage injection when purge control execution flag is in an ON state (YES in S400), and a step (S480) for substituting 0 into purge reduction amount calculation value fpgd on the injector side for cylinder injection and substituting a purge reduction amount calculation value fpg into the purge reduction amount calculation value fpgp on the injector side for intake passage injection and a step (S490) for calculating the final injection amounts of the injectors for cylinder injection and for intake passage injection when the injection sharing ratio r is neither 0 (NO in S430) nor 1 (NO in S460). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
