An emission analysis on the role of TiO2 additives in kusum oil methyl esters on working characteristics of CI engine

sathasivam, karthikeyan


The role of emission characteristics of a diesel engine has been investigated when titanium dioxide (TiO2) nano additive blended with Kusum oil methyl ester (KOME) are used as a fuel. Biodiesels produced from kusum oil by transesterification process. The additive ((TiO2) is added to B20 at a dosage of 50 ppm and 100 ppm. The kusum oilmethylester (KOME) is mixed with TiO2 nanoparticles with the aid of an ultrasonicator. The fuel properties of B20, (80% Diesel + 20% KOME), B20TiO2 50 (80% Diesel+20% KOME+50ppm TiO2) and B20TiO2 100 (80% Diesel+20% KOME+100ppm TiO2) have been studied and compared according to ASTM standard test methods for biodiesel. Tests are performed at full load CI (Compression Ignition) engine operation with a constant speed of 1500 rpm. The results show that the compression ignition engine works well and the power outputs are steady running with the selected biodiesels blends at different loads. The acquired data are studied for various parameters, such as exhaust emission of Hydro Carbon (HC), Carbon monoxide (CO), Carbon dioxide (CO2), Oxides of nitrogen gases (NOx) and smoke opacity.
