A Novel Comparative Study of Nanoparticles and EGR in DI CI Engine Fuelled by Biodiesels

Increasing energy demands, depletion of fossil fuels and stringent emission norm surged the scientific community to search for alternate fuels such as biodiesel for diesel engine applications which bridge the gap between demand and energy source for automotive sector. The quench of man’s desire of alternate fuel for current diesel engine and stringent emission norms of internal combustion engine are a challenging task that are brought in deep thought. Bio-fuels like ethanol and bio-diesel being environment friendly, will help us to conform to the stricter emission norms. International experience has demonstrated the advantages of using ethanol and methanol as automotive fuel. Since blends below 10% of ethanol do not present any problem and reduce harmful emission. The gases emitted by petrol and diesel driven vehicles have an adverse effect on the environment and human health. There is universal acceptance of the need for reducing such emissions. Biodiesel is one of the promising substitute source of energy fuel in the transportation sector due to rapid depletion of petroleum reserves on one side and increased energy demand as well as environmental pollution hazards on the other side, metal based additives along with the variations in physio-chemical properties, and its effect on performance and emission aspects.
