The fuel break up and atomisation processes in the near nozzle region of a second generation high pressure-swirl direct injection gasoline fuel injector have been characterised. The Phase Doppler technique has been used to measure the axial and radial droplet velocities and the resultant flow angles of the fuel droplets. Mean estimates based on time bin averaging the data over 20 microsecond time bins have shown that, during the transient formation of the hollow fuel cone there is a distinct high frequency fluctuation in the mean flow angle. Images of the spray cone have confirmed the fluctuations found by the PDA analysis and suggest that the phenomenon is due to waves in the spray cone which can be attributed to the instabilities behind the break up of the conical liquid sheet.
