Abstract
In this present research, investigate the performance, combustion and emission characteristics of variable compression ratio (VCR) engine fuelled with spirulina micro algae biodiesel(SMABD) (Arthrospira platensis and A. maxima) blends(B9, B18 and B27)for different compression ratio(14, 16 and 18) and loading conditions are studied. Different performance parameters such as brake power(BP), brake thermal efficiency(BTHE), brake specific fuel consumption(BSFC), emission parameters (CO,CO2,HC,NOx) has been compared with petro-diesel. BTHE is increased with compression ratio (CR) but it is higher for blend B18 at CR18 compared to other blends and diesel. BSFC is reduced when CR increases however it is lower for biodiesel blends than diesel. Emissions are greatly reduces for biodiesel blends. Finally it reveals that blend B18 at CR18 shown best results.
