Recently, the researchers is studying in-cylinder flowfield for saving the expansion and time in gasoline engine development. One of these research method, PTV(particle tracking velocity) method is used to low density flowfield. In this paper, we are studying for developing single frame-PTV algorithm. we compare invert distance interpolation method with invert distance-area interpolation one in intake valve lift 2, 4, 6, 8mm. The more the intake valve lift increases, the velocity is stronger. The tumble flow is enlarged. And the invert distance-area interpolation method is more sensitive than invert distance interpolation.<br/>
