Zusammenfassung:	An internal combustion engine uses gaseous main fuel and liquid pilot fuel and has a plurality of cylinders and an engine controller capable of adjusting a burning state of each cylinder through fuel regulation, including fuel cut off, upon occurrence of abnormal combustion. A method of operating the internal combustion engine includes, upon occurrence of abnormal combustion in a cylinder in a gaseous mode, cutting off the main fuel into only the cylinder and the fuel injection is kept partially active with a pilot fuel injected by a pilot nozzle of the cylinder.
