コージェネレーション機関におけるバイオディーゼル燃料の使用 -廃食油バイオディーゼルの利用技術開発

抄録

 Yanmar has conducted the research on the utilization of the so-called “FAME” bio diesel derived from waste cooking oil whose quality is worse than European bio diesel fuel standards (EN14214). However, it is an attractive carbon-neutral fuel which does not compete with food. In this study, several endurance tests were conducted on a diesel engine co-generation system using FAME of different properties. Tests show that with FAME fuel operation, lubricant oil dilution occurs due to mixing of unburned fuel. The low quality fuel which includes tri-glyceride led to more carbon deposits around injection nozzle tip causing higher smoke emission.
