| Abstract(J) | 副室ジェット燃焼方式は，超希薄燃焼を実現するために有効な技術である．本研究は，燃焼速度が速い，H2とCOを含む改質ガスを副室内で燃焼させ，主室燃焼の希薄限界を拡大することを目的とする．まず，一次元のモデルを構築し，必要の燃料噴射量，噴射時期と点火時期を調査した．そこで，調べた実験条件を，実機エンジンで評価を行い，λ=2.5の超希薄燃焼を実現し，正味効率とNOx排出濃度の目標達成が確認された． Translation |
| Abstract(E) | The pre-chamber jet combustion method is an effective technology for realizing ultra-lean combustion. The purpose of this study is to extend the dilution limit of combustion in the main chamber by burning reformed gas containing H2 and CO, which has a high combustion speed in the pre-chamber. First, a one-dimensional model was constructed, and the required fuel injection amount, injection timing, and ignition timing were investigated. Therefore, the experimental conditions investigated were evaluated using a real engine, and ultra -lean combustion with λ = 2.6 was achieved, and it was confirmed that the targets for net efficiency and NOx emission concentration were achieved. |
