Spray and combustion characteristics in biodiesel fuels / バイオディーゼル燃料の噴霧および燃焼特性 / バイオディーゼル ネンリョウ ノ フンム オヨビ ネンショウ トクセイ

Annisa Bhikuning 22 March 2020 (has links)
バイオディーゼルは、メタノールと触媒を使用したエステル交換プロセスによって製造されます。バイオディーゼルには、高セタン価、酸化安定性、低排出など、いくつかの利点があります。ただし、バイオディーゼルの高粘度と沸騰温度は、ディーゼルエンジンの噴霧燃焼に影響を与える可能性があります。したがって、高燃料と低沸点燃料を混合することでバイオディーゼルの特性を改善するために、新しい燃料設計法が適用されます。 / Biodiesel is one of the promising alternative fuels in the future. Biodiesel is made from the trans-esterification process that uses methanol or alcohol and catalyst. The use of biodiesel in diesel engine has some advantages such as high cetane number, oxidation stability and can reduce some emissions. However, high viscosity, boiling temperatures and surface tension in biodiesel may affect the spray characteristics as compared to diesel oil. To overcome the unbenefited in biodiesel, therefore, the new fuel designed method that high-boiling point fuel is mixed to a low-boiling point fuel is applied in order to improve the properties in biodiesels. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University
