ABSTRACT:
A system and method for measuring tip velocity of sprayed fuel in an engine includes a light source, a lens, a Charge-Coupled Device (CCD) camera, and a control unit. The lens allows light, which is emitted from the light source, to enter into a combustion chamber. The CCD camera photographs the shapes of the dispersion of the sprayed fuel. The control unit causes the light source to emit light two times by controlling the light source, acquiring a single frame image of the shapes of the dispersion of the sprayed fuel by controlling the CCD camera, and calculates the tip velocity of the sprayed fuel by processing the acquired image.
