Effect of adding Triacetin additive with Coconut oil methyl ester (COME) in performance and emission characteristics of DI diesel engine
Pages : 100-106
With the usage of diesel fuel and neat bio-diesel to some extent knocking can be detected in all the engines. Triacetin [C9H14O6] is a good anti-knocking additive and easily soluble in biodiesel. The usage of T- additive suppressed knocking, improved the performance and reduced tail pipe emissions. Comparative study was conducted using petro-diesel, bio-diesel, and with various additive blends of bio-diesel on DI- diesel engine. Coconut oil methyl ester (COME) is used with triacetin (T) at various percentages by volume for all loads (No load, 25%, 50%, 75% and full load). The performance of engine is compared with neat diesel in respect of engine efficiency, exhaust emissions and combustion knock. Of the five Triacetin-biodiesel blends tried, 10% Triacetin combination with biodiesel proved encouraging in the performance of engine in all aspects.
