Abstract
A prefilmer (26) for a fuel injection arrangement (10) comprising a body (50) having a fluid flow surface (80, 81, 82, 83) and a downstream edge (44), the prefilmer (26) arranged so that when working in operative association with the fuel injection arrangement (10) fuel flows over the surface (80, 81, 82, 83), by means of a passing airflow, to the downstream edge (44), from where the fuel is shed, characterised in that the prefilmer (26) further comprises a fluid flow mixing means (34) to, in use, enhance the mixing of fuel and air.
