Abstract: PROBLEM TO BE SOLVED: To provide a method of sequentially supercharging an internal combustion engine so as to assure a stable operation characteristic of the entire turbo supercharger of an internal combustion engine and match the turbo supercharger always to the optimum operating condition of the internal combustion engine. SOLUTION: When a load variation of an internal combustion engine is small, first the turbine lateral cross-section of at least a first exhaust gas turbo supercharger 3 is increased or decreased accordingly, and then aligned with a single or a plurality of turbine lateral cross-section. By this, when a specified switching time point where a load variation is not compensated for, one of the other exhaust gas turbochargers 4 is switched on or off. Upon one of the other exhaust gas turbochargers 4 is switched on or off, at least one turbine cross-section of the first exhaust gas turbochargers 3 is decreased or increased accordingly. Then, a produced load variation is adjusted accordingly to the turbine lateral cross-section of at least the first exhaust gas turbocharger 3 for new compensation.
