PROBLEM TO BE SOLVED: To provide a simulation method and a device of a four-cycle multi-cylinder gas engine capable of performing real-time simulation calculation of a performance of the four-cycle multi-cylinder gas engine by simulating operation of an actual engine by using a small-sized computer, and thereby optimizing easily a control function. SOLUTION: A cylinder model is used, wherein a cycle of each cylinder of the four-cycle multi-cylinder gas engine is classified into an intake stroke S1, a compression stroke S2, an expansion stroke S3 and an exhaust stroke S4, and the performance per cylinder in each cycle timeΔt is calculated. The engine performance of each cylinder portion is calculated simultaneously by shifting as much as the cycle time by using a shift function corresponding to the stroke order of each cylinder relative to all the cylinders of the four-cycle multi-cylinder gas engine, and results are integrated, to thereby calculate and realize the engine performance of the four-cycle multi-cylinder gas engine.
