Zusammenfassung:	In a method for controlling operation of an engine (10) according to the present invention, which an EGR system (36) is incorporated therein, when the engine is in a pressure-accumulable operational state in which EGR gas can be pressure-accumulated in an EGR passage (43a) between an EGR control valve (44) and an on-off valve (45), these valves are brought into a full closed state, respectively. In addition, when an intake pressure transmitted from an air intake passage (24a) to the engine becomes more than or equal to a target value of the intake pressure set based on an operational state of the engine, the on-off valve is switched to a full open state, and then the on-off valve is switched to the full closed state again after elapse of a predetermined time, and high-pressure EGR gas of a low oxygen concentration is temporarily stored in the EGR passage.
