Impact of rice husk nanoparticle on the performance and emission aspects of a diesel engine running on blends of pine oil-diesel.

With the increase in vehicle density, the amount of pollution along with the dependence on the diesel fuel also increases, which might be on the verge of depletion. The increase in fuel price is an important economical factor. Hence, finding a suitable substitute energy source which is economic and also meets the energy necessity is of great need. During this study, the utilization of pine oil biofuel in which rice husk (RH) nanoparticles was added as an additive was proposed. The test was carried out in a single cylinder, diesel engine at 1500 rpm. Fuel is blended at two ratios (B10, B20) and 0.1% of RH nano-additive is added with each blend and their characteristics in terms of performance and emission are analyzed for varied load conditions. At full load condition for B10-0.1% RH, there is a slight reduction of about 3.04% for BTE and 4.1% increase in BSFC than diesel fuel was observed. Likewise, for B20-0.1% RH at full load condition CO and HC decreases about 27.27% and 19.64% respectively, with a rise in CO2 and a slight increase of NOx level at 15.63%, 8.76% respectively than diesel fuel. This small replacement of diesel fuel by biodiesel helps in reducing the increasing cost and also the complete dependency on the fossil-based fuel. Thus, pine oil with additive can perform well without any engine modifications and helps in reducing the pollutions.
