Effect of Traditionally Synthesized Carbon Nano Particles as Bio-Fuel Blend on the Engine Performance

The demand for non-renewable energy resources is created due to the increase in number of vehicles and its pollution problems. This has been led to search for alternative and renewable energy resources. Different methods have been adopted to reduce emissions and to increase the efficiency of engines include, modification in engine, fuel alteration, and exhaust gas treatment. Recently it was reported that blending of nanoparticles with biodiesel to has brought about alteration in chemical and electrical properties which resulted in increased engine efficiency and decreased emission level. In the current study, carbon nanoparticles were synthesized by a simple traditional method. The structural characterization was done using SEM has revealed the average size of the particles in the range of 80.3–88.6 nm. The blend of carbon nanoparticle-biodiesel was utilized to evaluate the engine characteristics. Due to nano-additive biodiesel blend, a significant enhancement in the brake thermal efficiency with substantial reduction in the harmful pollutants from the engine was observed. Maximum brake thermal efficiency of 25 % was obtained for biodiesel blended with 50 mg of carbon nanoparticles with considerable reduction in hydrocarbons, smoke capacity, NOx emissions compared to 25 mg blend, biodiesel and diesel.
