Experimentation studies of microalgae biodiesel blends influence on variable compression ratio diesel engine performance and exhaust emission characteristics

摘要

Microalgae are found to be most competent and unswerving resource of biodiesel due to their attentional attributes like non-eatable, non-requirement of cropland for their cultivation. This work was directed to investigate the capability of novel, often overlooked biodiesel from microalgae species, which can be utilised as a substitute fuel in place of traditional diesel. The experimental investigation of the impact of biodiesel on performance along with exhaust emission characteristics of single cylinder diesel engine was researched. Various blends of microalgae biodiesel presented a reduction in torque and hence brake power resulting in average reduction of 7.14 in the BTE also 11.54 increase of BSFC as equated to petroleum diesel. With increase in blends ratio in diesel, there were considerable reductions in exhaust emission characteristics which are CO and HC. However, for all the algal biodiesel blends, NOx and CO_(2)increases but compatible and in acceptable range.
