Combustion characteristics of diesel spray impinging on a wall were investigated. Ambient temperature was varied from 500 to 620℃. Especially, the experiments for ignition position, ignition delay and flame area were performed to understand the effect of impingement distance. As the result, the ignition position reached to wide area under the conditions of high ambient temperature and short ignition delay. In that case, it seemed that complete combustion state was achieved. On the other hand, when the combustion was to be complete and ignition position was near a wall, the flame area became large. A model of the flame developing process was proposed to explain the effect of impingement distance on ignition position, ignition delay and flame area.
