| Abstract(J) | カーボンニュートラル燃料としてメタノールが注目されている．しかし，初留点，気化潜熱，低位発熱量の特性は，冷機時の燃焼安定性に大きな課題である．本研究では，燃焼改善の方向性を示唆するため，メタノール含有割合を変え，エンジン冷機始動での燃焼安定性，エンジン各所の温度分布，排出ガスの成分濃度等を調査した． Translation |
| Abstract(E) | Methanol is being studied as a carbon-neutral fuel for internal combustion engines. However, its physical properties, high latent heat of vaporization, boiling point and low specific calorific value, can present challenges for combustion during cold starts. In this study, using a spark ignited engine from a production motorcycle, we investigated fuel vaporization in the intake port, temperature distribution across engine components, and emissions from both the exhaust and crankcase, alongside combustion stability during cold starts. The results indicate that significant temperature drops and poor fuel vaporization in the intake port cause degraded combustion stability following the start-up. |
