Diesel engines are highly preferred for transportation since they are highly efficient and durable in the long run. However, because of the lack of crude oil reserves, fuel cost and emission norms, alternative fuels are of high interest to replace diesel fuel in diesel engines. Many alternative liquid fuels for diesel engines such as bio-diesel, alcohol have been introduced in the recent past. Today Most of the alternative fuels are biomass-derived and easily available. Many alternative fuel blends have been introduced in the past and they gave very satisfying results. Therefore, in this project, the eucalyptus oil which is high octane biomass-derived fuel is blended with diesel in different proportions by volume and used as fuel in the four-stroke single-cylinder diesel engine. The performance and emission characteristics of the engine were studied. The results show the reduction in consumption of fuel as the brake specific fuel consumption was found to decrease. The improvement in brake thermal efficiency is also observed. While the emission parameters were also improved, emissions were significantly reduced as the load was increasing.

Diesel engines are used in a wide range of industry such as agriculture, transportation, building and energy production due to their high efficiency. Besides, with the development in electronics technology diesel engines are being more and more used in automobiles. Because a good many of diesel engines are being used, we are in need of petroleum more than ever. On the other hand, it is also commonly recognized today that the world petroleum energy resources are finite, thus many researchers have been carried out to find suitable alternative fuels to petroleum products. Researches, on alternative fuels to petroleum based fuels, are increased since petroleum fuels are finite, as well as pollution resulted from their combustion have sincere affects on environments. It is important for an alternative diesel fuels to be technically acceptable, economically competitive, environmentally acceptable and easily available. Many researchers have concluded that biodiesel holds promise as an alternative fuel for diesel engines. Therefore, biodiesel can be used in diesel engines with few or no modifications. Diesel-fuel blends with biodiesel have superior lubricity, which reduces wear and tear
