Effect of Titanium Dioxide (TiO_2) Nano-Fluid on Performance and Emission Features of a Diesel Engine Operated on Aphanizomenon Flos Biodiesel-Diesel Blend

摘要

In this present investigation titanium dioxide (TiO_2) nano-fluid was blended with aphanizomenon flos (AF) biodiesel (20%)-diesel (80%) blend. Different percentages of TiO_2 such as 5%, 10%, and 15%, was added with AF-D (aphanizomenon flos-diesel) blends. The blends are named as AFD-5TiO_2, AFD-10TiO_2, and AFD-15TiO_2. The performance and emission parameters of a single cylinder CI engine fueled with AFD-TiO_2 blends were experimentally investigated. The results reveal that, with the use of TiO_2 nano particles, AFD-10TiO_2 blend gave optimum results. BSFC decreased by about 5% and BTE increased by about 2% with the addition of TiO_2 nano-particle as a catalyst. The tailpipe emissions such as CO, HC, smoke reduced drastically, but the NO emission increased, with the use of TiO_2 nano-particles.
