Study on Low Emission Condition in Dual Fuel Engine Using Natural Gas and Diesel Fuel

天然ガスと軽油を用いたDual Fuel 機関における 低エミッション燃焼成立条件の検討

The heat release rate and emission in dual fuel operation using natural gas and diesel fuel has been studied in conventional small diesel engine. High efficiency and very low emission combustion are obtained in the case of advanced injection timing and high ratio of natural gas condition. After that, the criteria for low emission has been investigated by analyzing the diesel fuel distribution using 3D-CFD. Finally, the authors have created the engine operation map for low emission combustion.天然ガスと軽油を用いたDual Fuel機関について,小型ディーゼルエンジンを用いて軽油燃料噴射時期,および,天然ガスと軽油の燃料割合が熱発生率や排ガスなどの燃焼特性に与える影響を確認した.また,3次元CFDを用いて着火時の混合気分布を分析することで,低エミッション燃焼成立条件の検討を行った.
