| Abstract(J) | 本研究では燃料の物理特性がディーゼル燃焼に及ぼす影響を明らかにすることを目的として，物理特性の異なる5種類の燃料を用いた実験を実施した．供試機関に単気筒ディーゼルエンジンを用い，2領域モデルで空気導入量を推算した結果，空気導入の早期化により従来よりも低い噴射圧においても微粒子低減が可能となった． Translation |
| Abstract(E) | In this study, experiments were conducted using five fuels with different physical properties in order to clarify the effects of fuel physical properties on diesel combustion. A single-cylinder diesel engine was used as the test engine, and the air entrainment rate was estimated using a two-zone model. The results showed that earlier air entrainment enabled particulate matter reduction even at lower injection pressures than those used conventionally. |
