| Abstract(J) | CN燃料の一つであるメタノールは，燃料の初留点，気化潜熱，低位発熱量の特性から，冷機時の燃焼に課題がある．二輪車用単気筒エンジンでガソリンとメタノールの混合比を変えた燃料を用い，冷機燃焼の改善策を模索した．燃焼解析，排出ガス等の分析等のデータから，低い燃料蒸発割合を補うことが有用であることが判明した． Translation |
| Abstract(E) | Methanol is currently under investigation as a carbon-neutral fuel for engines. However, its properties, such as its low boiling point and latent heat, pose challenges for cold-start engine combustion. In this study, we investigated a production motorcycle spark-ignited (SI) engine. Our research focused on fuel vaporization in the intake port, temperature distribution around engine components, and exhaust and crankcase gas emissions, alongside combustion stability during cold start. We found that poor fuel vaporization in the intake port were the root cause and the improvement target for degraded combustion stability following engine startup. Oil dilution may constitute a separate, critical issue. |
