This study investigates the use of two specific alcohols, octanol and deconal, alongside diesel and biodiesel derived from Cymbopogon citratus. Two ternary blends, labeled as D50-CC30-OCT20 and D50-CC30-DEC20, were formulated and analyzed to assess their engine performance compared to the D50-CC50 blend, pure diesel operation. Results indicate a decrease in peak cylinder pressure with the use of ternary blends. The maximum rate of heat release was observed to be higher in the octanol-containing blend. Furthermore, the deconal blend exhibited a 2.5% improvement in brake thermal efficiency (BTE) compared to octanol yet remained 3.5% lower than traditional diesel operation. Notably, the NOx emissions of the deconal blend were 4% lower compared to octanol. Overall, higher alcohol blends led to reduced smoke emissions compared to binary blends. Octanol, specifically, showed a 15% decrease in smoke opacity. However, the emissions of hydrocarbons (HC) and carbon monoxide (CO) increased with the use of greater alcohol blends. This research underscores the potential of 1-deconal as a viable fuel option for diesel engines running on biodiesel derived from Cymbopogon citratus oil sourced from biomass.
