A fuel injection insert (2) is provided for injecting fuel in the channels to pre-mix air and fuel. The fuel injection in a channel is predetermined by the arrangement of a fuel injection insert in twist generator segments. Independent claims are also included for the following: (1) a fuel injection insert with an insert body; (2) a twist generator segment with a triangular cross-section; and (3) a method for injecting fuel in a gas turbine.
