Abstract:
Control apparatus for an engine includes a failure determination unit which determines whether there is a failure in an operating engine, and an A/F (air-fuel ratio) feedback control unit which performs feedback control to bring actual A/F in the engine to a target set in advance. The failure determination unit includes a failure determination section, a failure code storing section, a similar operating condition recording section, and a return-to-normal control section. The A/F feedback control unit includes an A/F target setting section, and the target set is stored in the similar operating condition recording section as a factor defining the operating condition of the engine. The return-to-normal control section eliminates the failure code if the failure determination section does not determine that there is a failure when the engine is operating in an operating condition similar to that recorded in the similar operating condition recording section.

Claim (Index 4):
The control apparatus according to  claim 3 , wherein the failure determination section determines whether there is a failure in the engine based on accumulated difference obtained by summing differences between actual A/F and the target set by the A/F target setting section, and learned A/F value updated to curb an increase in the accumulated difference on a \u201crich\u201d or \u201clean\u201d side.
