Influence of Additive on the Performance and Emission of Biodiesel Fueled Diesel Engine

As an alternative fuel biodiesel can be played an important role to meet the future energy demand. Biodiesels have lot of good advantages over diesel which attract the users to use it as the substitute of diesel. It has huge biodegradability, less environmental impact, higher flash point and cetane number, higher lubricity and so on. However, for the widespread practical applicability of biodiesel more investigation is required related to the engine performance and emission. In this paper the effect of additives (1% and 2% with 20% blended biodiesel) on the performance and emission is investigated in an Isuzu 4FBI four-cylinder diesel engine. The break power and the break specific fuel consumption was measured using computer controlled eddy current dynamometer and the load cell arrangement, while the emission parameters was investigated using Bosch and Bacharach exhaust analyser. Investigations result implied that 1% additives with 20% blended biodiesel (B20+1 %.) showed better performance as compared to diesel, pure biodiesel (B100), 20% blended biodiesel (B20) and 20% biodiesel with 2% additives (B20+2%) with respect to overall engine performance and emission.
