Tri-fuel emulsion with secondary atomization attributes for greener diesel engine – a critical review

Utilization of tri-fuel emulsion (a composition of diesel, biodiesel, and alcohol) has been introduced to alleviate existing drawbacks of diesel engines by means of reducing the level of emissions without compromising its power output. Tri-fuel is proposed to facilitate the efficient performance of...
