Abstract (en)
[origin: EP2014988A1] The system has an annular expansion ring (20) that is coaxial with a fuel injector, a primary spin that is coaxial with the ring, and a venturi placed downstream of the spin. The ring has an annular slot (32) that is convergent tapered towards downstream and opened towards downstream. An axis of each hole (26) of the slot forms an angle with a main axis (A) such that air releasing the holes impacts a lower wall (38) of the slot near the main axis. The angle is strictly higher than an angle formed by a cone surface defining the slot with the main axis.
