PROBLEM TO BE SOLVED: To provide an on-board control device for an internal combustion engine that prevents an occupant from building a feeling of discomfort, caused by a blowing rate of fuel injected from a port injection valve and an in-cylinder injection valve during an idle operation being changed.SOLUTION: When the port injection valve 14 is set as an injection valve for injecting fuel during the idle operation, an electronic control unit 100 allows the injection valve for injecting fuel to be changed from the port injection valve 14 to the in-cylinder injection valve 12 if a deposit accumulation amount DP is larger than a predetermined amount DPth. Meanwhile, the unit prohibits the injection valve for injecting fuel after this change from being changed to the port injection valve 14. |
