Performance and Emission Characteristics of CI Engine Using Biodiesel (Cotton Seed Oil) Blends with Titanium Oxide

In this work, experimental investigation was carried out to test the performance and emission characteristics of a CI engine using diesel and cotton seed oil methyl ester blended fuel (COSME20) along with titanium oxide nano particles as an additive in biodiesel blends. The titanium oxide nanoparticles promote the combustion process that results in more oxidation of CO and reduces HC emission. The engine test was conducted with various blends of diesel and biodiesel with and without nanoparticles, namely B20 (20% biodiesel+80% diesel), BN20 (20% biodiesel+80% diesel+20ppm), BN40 (20% biodiesel+80% diesel+40ppm) at different loads. The test results showed that the addition of titanium oxide nanoparticles in diesel and biodiesel blends improved combustion and reduced the exhaust gas emissions significantly.
