In this research, optimum spray atomization is verified in the liquid injection with the microwave heating technology, the local contact microwave heating. The fuel used was ethanol, which isvaluable in biomass-origin fuel. The fuel was jetted seven times, once every five seconds. The experiment time was 30 seconds. The spray was photographed using a 130 Mpix color CMOS digital camera. The feature of the spray that could be appreciated by the pictures was defined as the droplet dispersion area. The photographs were qualitatively evaluated with simple image data prpcessing. As a result, the droplet dispersion area was increased with microwave heating. This shows that there is a possibility of change through spray atomization.
