1. The method of operation of a large two-stroke diesel engine (1) with longitudinal blowing of cylinders having a piston (20), made with the possibility of reciprocating movement in the cylinder (2) on the working surface between the bottom dead center (UT) and top dead center (OT ), while the fuel is supplied to the cylinder (2) of a large diesel engine (1) with an injection nozzle, and purge slots (3) are provided in the inlet region of the cylinder (2) to supply a predetermined amount of purge air (4), and in the cylinder cover, in the cylinder re (2), there is an exhaust valve (5) for the release of gaseous products of combustion (6), and when implementing the above method, fresh air (7) coming in at ambient pressure is sucked in by the first exhaust gas turbocharger (8, 81) and / or a second exhaust turbocharger (8, 82), and the aforementioned fresh air (7) is supplied to the cylinder (2) as purge air (4) at a given pressure of the charge air through the purge slots (3), so that in the cylinder (2) a flammable gas mixture is formed from the purge about air (4) and fuel, characterized in that at least one reduction means (9, 91, 92, 93) is provided for reducing the exhaust gas flow rate through the first exhaust gas turbocharger (8, 81) and / or through the second exhaust gas turbocharger (8, 82), as a result of which, when implementing the aforementioned method, the exhaust gas flow rate through the first exhaust gas turbocharger (8, 81) and / or through the second exhaust gas turbocharger (8, 82) is reduced depending on the set value of the operating parameter of a large diesel engine (1
