Effect of Nano fuel Additives in Emission Reduction of Blended Biodiesel

Abstract
B20 has proven to be a practical fuel that can be used in any diesel engine with few precautions or changes. Most of the industry believes that blends up to 20% (B20) will cause no harm to performance. However the use of blends over 20%, can leave harmful impacts on equipment and fuel systems changing its cold flow properties, material compatibility, maintenance intervals, fuel stability, biological growth, energy content, emissions and overall handling. A successful attempt was done by adding nanoparticles (25 ppm and 50 ppm) in higher blended biodiesel (B30 and B40) using ultrasonicator for proper dispersion and for improving the stability of the blends. The results showed significant enhancement in some thermo-physical and combustion properties of the resulting suspension, where lower dosing level of NPs further improved the performance of the engine. The performance and emission is carried out in a single cylinder four stroke diesel engine for an each combinations in order to get the maximum performance and minimum emission levels. As a result of this study, engine emission values NOx and CO were decreased and engine performance values slightly increased after the successful addition of nanoparticle additives.
