An experimental investigation was carried out to evaluate performance and emission characteristics of single cylinder, air cooled diesel engine running at constant speed of 1500 rpm using multiwalled carbon nanotube (MWCNT) blended diesel and karanja biodiesel. The multiwalled carbon nanotubes are blended with diesel and biodiesel in three different proportions of 50mg/lit, 100 mg/lit and 150 mg/lit. The stable and homogeneous blends of diesel and biodiesel with MWCNT were prepared using ultrasonic bath stabilizer. The whole experiment was carried out using following fuels: neat diesel, biodiesel and MWCNT blended diesel and biodiesel accordingly. The experimental results showed that addition of MWCNT in fuel results in increase brake thermal efficiency and reduced brake specific fuel consumption. At full load, brake thermal efficiency for diesel and biodiesel was 29.13% and 32.92% respectively, where as it was 32.92% and 27.48% for Diesel+MWCNT150 (150 mg/lit MWCNT blended diesel) and KME+MWCNT150 (150 mg/lit MWCNT blended biodiesel) respectively. The hydrocarbon emission reduced by 23.07% and 27.58% for Diesel+MWCNT150 compare to neat diesel and KME+MWCNT150 compared to neat biodiesel respectively. There was also reduction in carbon monoxide emission with a reduction of 35.13% and 38.89% with Diesel+MWCNT150 compare to neat diesel and KME+MWCNT150 compared to pure biodiesel respectively at full load. There was slight increase in oxide of nitrogen and carbon dioxide emission with MWCNT blended diesel and biodiesel.
