小型高速機関でのいわし油燃焼試験 漁船機関への代替燃料としての魚油の可能性 Study on Fish Oil as a Fuel Substitute for Diesel Engines Hasegawa, Katsuo 589 長谷川, 勝男 10372070 ハセガワ, カツオ Oda, Ken-ichi 2031 小田, 健一 80372077 オダ, ケンイチ Yamada, Toshio 3525 山田, 敏夫 ヤマダ, トシオ Engine tests were carried out with several mixing ratios of fuel between fish oil and diesel oil on a small high speed diesel engine. The results obtained from the combustion analysis were not influenced by the mixing ratio on combustion characteristics. Still the period of starting up was longer as the mixing ratio increased. Piston ring wear and carbon deposit in combustion chamber were increased with the mixing ratio of fish oil on the continuous operation test. Also, lubricating oil showed deterioration for some properties by using fuel blended fish oil. These appearances were more notable when the mixing ratio was made larger. It was showed that the combustion performance of fish oil could be sufficiently adapted as a fuel substitute for diesel engines. However, an engine is influenced by means of fish oil when the long continuous operation so that it needs cares to avoid troubles in the practical use of it. (1) 燃焼に関しては着火遅れ等の燃焼状態は魚油混合率に依存せず,軽油と比較して顕著な差はなかった。しかし,起動性,燃費率は若干悪くなった。(2) 耐久試験では魚油混合率が20%,80%と大きくなるほどピストンリングの摩耗,燃焼室周りの汚れとも増加した。潤滑油の全塩基価の低下と不溶分の増加がみられた。また,燃料希釈による動粘度と引火点の低下が起こった。(3) 耐久試験中,魚油80%の低負荷運転において,燃費率が運転時間の経過とともに大きくなるなど,魚油燃料燃焼の影響は特に低負荷運転時に顕著であった。 departmental bulletin paper 水産工学研究所 National Research Institute of Fisheries Engineering 1990-03 水産工学研究所研究報告 11 161 172 Bulletin of National Research Institute of Fisheries Engineering AN00332937 0388-9718 https://fra.repo.nii.ac.jp/records/2007813 jpn nrife_k_11_161 日本農学文献記事索引(agriknowledge) https://agriknowledge.affrc.go.jp/RN/2010460576 metadata only access
