| Abstract(J) | 希薄燃焼の実用化における課題の一つである未燃炭化水素の生成要因を明らかにし，ガソリンエンジンの熱効率向上手法を提案することを目的として，高速FIDやNDIRを含む排気ガス分析計，熱流束センサ，およびCN燃料として期待されるエタノール混合燃料を用いて，燃焼特性および未燃炭化水素の生成・排出挙動を解析した． Translation |
| Abstract(E) | Incomplete combustion and associated unburned hydrocarbon (UHC) emissions remain critical challenges limiting the application of lean-burn combustion as a high-efficiency engine operating strategy. In this study, combustion characteristics and UHC formation and emission behavior were investigated under lean-burn conditions using an exhaust gas analysis system equipped with Fast FID and NDIR, together with heat flux sensors. The dominant factors governing exhaust UHC emissions were identified. |
