Effect of Nano-TiO2 Additives Blended in Palm Biodiesel on Compression Ignition Engine Performance

Abstract—The property improvement of palm oil biodiesel (POB) was investigated by mixing a nano-TiO2 additive in order to achieve in the decrease of exhaust emissions of a diesel engine. The different POB fuel fractions were used including B10, B20, B30, B40, B50, and B100 which are compared with commercial diesel B2 as a fuel standard. The results suggested that the small amount of 0.1% wt nano-TiO2 additive provided the property improvement such as a decrease in kinematic viscosity and an increase in flash point, cetane index, and heating values. However, there are B2+0.1%TiO2 and B10+0.1%TiO2 providing their properties to be accepted in ASTM standard. The experimental results suggested that engine power and torque increased during the range of low engine speed (<2500 rpm) and became decreased during the higher range of engine speed (>3000 rpm). Carbon oxide (CO), carbon dioxide (CO2), and nitric oxide (NOx) emissions were measured directly at the tailpipe in order to observe the effect of POB fuel used on the gas emissions. It was found that nano- TiO2 additive significantly contributed the reduction of CO2 and NOx emissions.

Index Terms—Palm biodiesel, nano-TiO2 additives, compression ignition, engine performance.
