Abstract :
An experimental investigation was carried out to evaluate the effect of using Triacetin (T) as an additive with biodiesel on direct injection diesel engine for performance and combustion characteristics. Normally in the usage of diesel fuel and neat biodiesel, knocking can be detected to some extent. By adding triacetin [C9H14O6] additive to biodiesel, this problem can be alleviated to some extent and the tail pipe emissions are reduced. Comparative study was conducted using petro-diesel, biodiesel and additive blends of biodiesel on the engine. Coconut oil methyl ester (COME) was used with additive at various percentages by volume for all load ranges of the engine viz. at no load, 25%, 50%, and 75% of full load and at full load. The performance is compared with neat diesel in respect of engine efficiency and exhaust emissions. Among the all blend fuels tried, 10% Triacetin combination with bio-diesel shows encouraging results
