ABSTRACT:
A method and apparatus for operating an engine with a plurality of cylinders, which are capable of appropriately controlling the engine after the cutoff of fuel into a cylinder having heavy knock, without at once stopping the engine upon the detection of the heavy knock. The method of operating the engine, which is capable of stepwise or continuously correcting a burning state through fuel regulation including the cutoff of fuel, upon occurrence of abnormal combustion, executes a stop or output limit operation on the engine. The method includes setting a simulated abnormal combustion, and determining abnormal combustion of a cylinder by comparing a detection signal as to a burning state of a cylinder, which is sequentially selected, with the simulated abnormal combustion signal to determine abnormal combustion in order to execute a cutoff of fuel into the selected cylinder.
