    • Depending on the actual operating situation and the composition of the fuels used for driving the internal combustion engine, contamination of the moving blades, of the guide device and of the turbine casing parts occurs sooner or later in the exhaust gas turbine. According to the invention, a small quantity of cleaning fluid is fed continuously or cyclically into the exhaust gas flow of an exhaust gas turbine and is directed onto the components to be cleaned. The small quantity of cleaning fluid can be fed in with unchanged operation of the internal combustion engine, such that the exhaust gas turbine can be cleaned or kept clean within the entire operating range of the internal combustion engine. Fluctuations in the power output of the internal combustion engine on account of requisite cleaning of the exhaust gas turbine therefore do not occur. Furthermore, the formation of thermostress cracks in the critical turbine casing parts is largely avoided.
    • 根据实际操作情况和用于驱动内燃机的燃料的组成,引导装置和涡轮机壳体部件的动叶片的污染早在废气涡轮机中发生。 根据本发明,少量的清洁流体被连续地或循环地进料到废气涡轮机的废气流中,并被引导到待清洁的部件上。 能够以不变的内燃机的动作供给少量的清洗液,从而能够在内燃机的整个工作范围内清洁或保持排气涡轮。 因此,由于排气涡轮机的必要清洁,内燃机的动力输出的波动不会发生。 此外,在很大程度上避免了临界涡轮机壳体部件中的起火器裂缝的形成。
