Claims5
A turbine unit of a turbocompressor, the turbine unit comprising:
- a turbine wheel having blades, each blade having a tip, a means defining a flow passage for directing exhaust gas to the turbine wheel, the flow passage having a surface surrounding the tips of the turbine, blades, and
- an injection means for injecting carbon build-up preventing substance into the flow passage, the injection means defining channels opening into the flow passage at the surface surrounding the tips of the turbine blades in an area between front and rear parts of said tips.
A method of operating a turbine unit of a turbocompressor, the turbine unit comprising a turbine wheel having blades and a means defining a flow passage for directing exhaust gas onto the turbine wheel, said method comprising injecting carbon build-up preventing substance into the flow passage through channels that open into the flow passage at a surface surrounding tips of the turbine blades in an area between front and rear parts of said tips.
