Attaining simultaneous reduction in nox and smoke by using water-in-biodiesel emulsion fuels for diesel engine

This paper presents the study of water-in-biodiesel emulsions (WiBE) stabilized by surfactants with different hydrophiliclipophilic balance (HLB) on a single-cylinder diesel engine. The engine performance and exhaust emissions were compared against the base fuel biodiesel (B5 diesel) which contained...
