| Research Abstract |
In this study, using droplet dripping and evaporation test rig, over ten thousands fuel droplets were dripped on a hot surface repeatedly, and evaporation deposits formed from them were quantitatively analyzed. Then, hot surface temperature and dripping interval were discussed with formation mechanism of evaporation deposits. Under various surface temperatures with fixed dripping intervals for diesel fuel test, developed test rig showed that it could be useful for simple evaluation method of evaporation deposits. Results show that wet-dry condition and hot surface temperature were main controlling factors of deposits development. Empirical equations of deposits development were derived from the experimental results. Further carbonaceous evaporation deposits from RME were around ten times serious than diesel fuel.
