In a high-speed DI diesel engine, injected fuel sprays impinge on the wall of piston cavity. In the experiments presented here, diesel fuel was injected into a high temperature and pressure chamber in which compressed N₂ gas. In this studies, We examined about impinging spray considering ambient density(18, 24, 30 ㎏/㎥), ambient temperature(293, 473K), impingement angle(0, 30, 45˚). The images of impinging spray were obtained by the high speed video camera. After that we analyzed the impinging spray characteristics to use the images. |
