Abstract
The present study investigates the suitability of marine microalga Chlorella vulgaris BDUG 91771 biodiesel to curb the fuel crisis, based on engine performance and emission profile. Initially, biodiesel was produced from outdoor grown Chlorella vulgaris BDUG 91771 and its fuel properties accorded with ASTM D6571 and EN 14214 standards. To evaluate performance and emission characteristics, various Chlorella vulgaris BDUG 91771 biodiesel-diesel blends were prepared and tested in single-cylinder Kirloskar engine under four different load operations (0%, 50%, 75%, 100%). Compression ignition engine fuelled with B40 or B50 biodiesel-diesel blend showed specific fuel consumption (SFC), and brake thermal efficiency (BTE) of 0.306Â kg/kWh and 26% respectively at 100% load, which is on par with diesel fuel. Further, engine operated with B50 biodiesel blend evidently reduced the carbon monoxide (CO) and hydrocarbon (HC) emissions by 0.1% and 102Â ppm respectively compared to baseline diesel. Notably, diesel emitted 7.5% carbon dioxide (CO2) and 380Â ppm nitrogen oxides (NOx) at 100% load, while the optimal blends B40 or B50 reduced CO2 and NOx emissions by 6.1% and 376Â ppm respectively. Based on results, present work suggests either B40 or B50 Chlorella vulgaris BDUG 91771 biodiesel - diesel blend could serve as eco-friendly, alternative fuel.
