CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine, suppressing occurrence of problems when failure detection in a direct injection system is performed and fuel is injected from only one of a port injection system and the direct injection system, in the internal combustion engine having two injection systems.

SOLUTION: An engine ECU 10 performs failure detection in an injector 200 for port injection or an injector 210 for direct injection based on output torque fluctuation amount. When any failure is detected, an air flow adjusting valve 220 is controlled to increase a flow of air in a combustion chamber so as to suppress fluctuation in output torque of an engine 100.
