| Abstract(J) | 代替燃料として期待されるアルコールをディーゼルと同様に拡散燃焼させるため,着火源としての軽油をエタノールと同一噴孔から噴射する2燃料噴射弁を試作した.軽油流路内に絞りを組込み,主噴射中の軽油割合を低減することで,軽油割合が高負荷より高くなる低~中負荷で,smokeを大幅に低減できることを実証した. Translation |
| Abstract(E) | Alcohol fuel, namely methanol and ethanol, are promising fuel for diffusive combustion in heavy-duty diesel engines, while they are difficult to self-ignite. In this study, a prototype dual-fuel injector that injects diesel fuel as an ignition source from the same nozzle with ethanol was developed. By installing a small orifice into the diesel flow path and reducing the diesel proportion during the main injection, we demonstrated that smoke can be significantly reduced even under medium-load conditions where the diesel proportion is relatively high. |
