The subject of the invention is a method as well as an apparatus for suppressing flow vortices within a turbo power machine with a premix burner, into which fuel and air are introduced for mixing, which then leave the burner downstream along its burner axis in the form of a fuel/air mixture through a burner outlet and flow into a combustor located downstream from the burner in the flow direction of the fuel/air mixture. The invention is based on the basic idea of-for the fluid-mechanical stabilization of a premix burner, into which at least one combustion air stream (5) is fed tangentially into a burner chamber (6) and is mixed with an injected gaseous and/or liquid fuel (7;8) while forming a swirl flow (9) oriented coaxially to the burner axis and induces a reverse flow zone (15) at a change in the cross-section on a burner mouth (14), that is used during the operation of the burner to stabilize the flame-increasingly, radially deforming the swirl flow (9) within the burner chamber (6) in the direction of the burner mouth (14) and let it enter the combustor (12) in a non-rotation-symmetrical flow cross-section, whereby this deformation is created by reducing the free flow cross-section (18) of the burner chamber (6). The fuel/air mixture flows into the combustor with a non-rotation-symmetrical flow cross-section.

A state in which a vehicle travels while an internal combustion engine drive torque (Te) is transmitted to a driving wheel wherein, Te and a clutch torque Tc are reduced and an electric motor torque (Tm) is increased based on the fact that a shift up condition has been established (t1). Thereafter, based on the fact that Tc is zero (t2), Tc is maintained at zero, and while maintaining a state in which Tm is transmitted to the driving wheel, a shift up operation is performed (t2 - t3). Then, based on the fact that the shift up operation is complete (t3), Te and Tc are increased and Tm is reduced (T3 - T5). After the shift up condition has been established, during the time until Tc becomes zero, the load torque (Ts) of a generator rotatably driven by the power shaft of the internal combustion engine is generated. In a hybrid vehicle equipped with an AMT, the power consumption accorded to the electric motor drive when shifting up while using the assist for the electric motor torque can be reduced.
