Abstract: The extensive use of biodiesel as an alternate fuel has resulted in the oversupply of glycerine, leading to an increased demand to look for the use of glycerine as an alternate fuel. In this paper, multiple blends of diesel-biodiesel and their glycerine emulsions were compared to investigate the performance and emissions in a modern small diesel engine. A direct injection diesel engine was tested at different loads and speed conditions. Biodiesel was produced onsite and crude glycerine obtained as a by-product was purified using an orthogonal test method. Hydrophilic-lipophilic balance was formulated using two surfactants: Polyoxyethylene Sorbitan Monooleate and Sorbitan Monooleate, which were used in the emulsification process to attain desired stability of glycerin emulsion.
