Comparative studies of a bioethanol fuelled DI diesel engine with a cetane improver

Abstract

Flowers of madhuca indica tree are found to be a potential source for bioethanol production. The present work is aimed to study the effect of diethyl ether (DEE) as a cetane improver on engine behaviour when the DEE is added to bioethanol diesel emulsion in little quantities and used as fuels. 1% and 2% of DEE were added on a volume basis to BDE15 (bioethanol-diesel emulsion up to 15%) and named as BDED1% and BDED2% respectively. The combustion, performance and emission results were compared with those of diesel operation. The results showed that the bioethanol diesel emulsion operation, with and without the cetane improver, showed a higher brake specific energy consumption and exhaust gas temperature than that of diesel operation at maximum brake power. There was a simultaneous reduction of brake specific nitric oxide (BSNO) and smoke emission with the addition of cetane improver in bioethanol diesel emulsion.

Modeling biomass-based biofuel production and developing a reference energy system for the agricultural sector in Turkey

“…Biodiesel is generally produced from the plants' oils of canola, corn, and cotton. Also, bioethanol is produced, mostly from the syrup of sugar beets and sugar cane by following some processes, as seen in Figure 4 (Hansdah & Murugan, 2016). The hexane catalyst is added as a solvent to the raw material when producing biodiesel in the biofuel production process.…”
