| 摘要 |
The present invention relates to a method for regulating the turbine power of a turbo (7) in an internal combustion engine (1), the internal combustion engine comprising an exhaust-driven turbine (9) with elements (30) for guiding the exhaust gas flow to the turbine wheel (31), which guide elements (30) are adjustable within a range defined by a first end position (A) and a second end position (C) for the purpose of regulating the quantity of exhaust gases through the turbine (9). The method is characterized in that, when there is a medium to large exhaust gas flow, the guide elements are adjusted into a guide element position (F) which lies within a subrange (D, E) of the range (A, C), which subrange (D, E) includes at least one guide element position with a higher turbine efficiency than the guide element positions outside the subrange have, and exhaust gases which are regarded as superfluous when the guide elements (30) have been adjusted into the guide element position (F) are bypassed past the turbine (9) in order for it to be possible for the desired turbine power to be obtained.
