Control apparatus for internal combustion engine

摘要

An engine ECU executes a program including the steps of: determining presence of abnormality in a high-pressure fuel system (S100); when abnormality is sensed in the high-pressure fuel system (YES at S100), and not in an in-cylinder injector (NO at S 110), injecting fuel from the in-cylinder injector at the feed pressure (S120); selecting criteria (1) that is the restriction standard for a more gentle output restriction of the engine (S 130); when abnormality is sensed in the high-pressure fuel system (YES at S 100) and in the in-cylinder injector (YES at S110), ceasing the in-cylinder injector (S 140); selecting criteria (2) that is the restriction standard for a stricter output restriction of the engine (S150); increasing the VVT overlap (S160); retarding the ignition timing (S170); and restricting the throttle opening according to the selected criteria (S 180).
