<div class="section abstract"><div class="htmlview paragraph">In internal combustion engine, it is necessary to grasp droplet evaporation for using liquid fuel efficiency and improving exhaust gas composition. However, it has not known completely yet. In this study, fuel droplet of approximately 20μm diameter that is assumed to be in combustion chamber is injected by experimental apparatus. After that, droplet goes to butane flame. We observed by high-speed camera, and experimentally considered the effects of heat flux on the fuel droplet evaporation and breakup phenomenon. For the sample fuel, we use kerosene and diesel oil. It is important for understanding evaporation condition to know temperature around droplet in butane flame. Thus, flame temperature is measured by sheathed thermocouple. Heat flux is changed by initial velocity. From experiment, we found some result. Time that from injector tube to location of breakup of the droplet is short by increasing heat flux. In terms of breakup phenomenon, it is found that kerosene is broken up in relatively small heat flux condition. The breakup diameter is not dependent on heat flux. Evaporation rate is increased linearly by increase in heat flux. The value of evaporation rate that kerosene and diesel oil is almost equal.</div></div>
