| Abstract(J) | 天然ガスディーゼルデュアルフュエル機関の量論比運転では低負荷における失火や燃焼変動の増大が課題である．本研究では，単気筒試験機関を用いて量論比運転を行い，吸気温度，圧縮比，軽油噴射時期，EGRが性能・排気に及ぼす影響を調査し，混合気の圧縮条件と低負荷限界の関係を明らかにした． Translation |
| Abstract(E) | The effect of diesel-fuel injection timing, intake temperature, compression ratio, and EGR ratio on the engine performance and emissions were investigated using single-cylinder test engine to lower the low-load operation limit. As a result, it was found that the engine could not be operated when the intake pressure (input energy) was reduced because the ignition by diesel fuel did not occur, and that the low-load operation limit was expanded by increasing the compression temperature and puressure through the increase in compression ratio and the use of EGR. And, the relationship between compression temperature and pressure at the low-load operation limit was summarized. |
