| Abstract(J) | 水素は多様な再生可能エネルギから製造可能であり，水素エンジンはCN実現の選択肢の一つとして検討が世界的に広まっている．異常燃焼抑制や高効率化には，直噴での圧縮行程噴射が有効だが，一方で混合時間が短くなるため，混合気が不均質となりやすく，低NOxとの両立が課題である．本研究では可視化に基づいたガス噴流MBD手法を構築し，均質な混合気形成を実現する指針を検討した． Translation |
| Abstract(E) | Hydrogen can be produced with various renewable energy, so hydrogen engines are being developed worldwide as an option for the realization of Carbon Neutrality. Direct injection during compression stroke is effective for suppressing abnormal combustion and increasing efficiency, but shorter mixing time often causes inhomogeneous mixture and NOx emission. In this study, a gas jet MBD method based on visualization was developed and guidelines for achieving homogeneous mixture formation were investigated. |
