Abstract
Results were compared with those achieved with the use of neat diesel fuel. They tested 1-butanol/diesel fuel blends and 1-pentanol/diesel fuel blends. Experimental results showed a slight engine power loss and an increase in brake thermal efficiency when the engine was fueled with higher alcohols blends instead of straight diesel fuel. However, some 1-butanol blends showed a decrease in the brake specific fuel consumption compared to the use of neat diesel fuel. After using 1-butanol blends and 1-pentanol blends, no engine performance problems were visually detected. In addition, statistical analysis showed no significant differences between tests. It can be concluded from this field trial that a diesel engine, without any modifications, can run successfully on a blend up to 30% 1-butanol/70% diesel fuel or 25% 1-pentanol/75% diesel fuel without externally apparent damage to the engine parts.
