    • 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。

    • The rotor blades (11) and hub (10) of the compressor wheel (1) are cleaned by means of a cleaning fluid stream (72) directed along the rotational axis (A) of the compressor wheel onto the compressor wheel. The cleaning fluid stream is run towards or sprayed at the compressor wheel by a supply nozzle (51) arranged on the axis and directed along the axis in the direction of the compressor wheel. The supply stream (72) thus follows the axis and hits the rotational centre of the compressor wheel on the hub of the compressor wheel. The cleaning fluid is thus introduced on the compressor wheel at the rotational centre of the compressor wheel. The cleaning fluid thus runs along the surface of the hub and is carried radially to the radially outer regions by the centrifugal forces.
    • 压缩机叶轮(1)的转子叶片(11)和轮毂(10)通过沿着压缩机叶轮的旋转轴线(A)指向压缩机叶轮的清洁流体流(72)来清洁。 清洁流体流通过布置在轴线上的供应喷嘴(51)朝向压缩机叶轮或喷射在压缩机叶轮上并沿着轴向在压缩机叶轮的方向上引导。 供应流(72)因此遵循轴线并且撞击在压缩机叶轮的轮毂上的压缩机叶轮的旋转中心。 因此,清洁流体在压缩机叶轮的旋转中心处被引入到压缩机叶轮上。 清洁液因此沿着轮毂的表面延伸并且通过离心力径向地径向延伸到径向外部区域。
