An advanced laser 2-focus velocimeter (L2F) has been applied to the measurement of droplet velocities and sizes in a dense region of diesel fuel spray. The maximum rate of data sampling of the L2F was set at 15 MHz. The fuel was injected into the atmosphere by using a common rail injector. The rail pressure was set at 40 and 70 MPa. The nozzle hole diameter of the injector was 0.113 mm. The L2F can detect droplets just after the spray tip reaches the measurement position 30 mm downstream from the nozzle. The result of the measurement shows that the higher injection pressure leads the higher droplet velocity in the core of the spray. It is clearly shown that the smaller droplets after active disintegration are dispersed spatially under higher injection pressure.
