Biodiesel was produced on site by a transesterification process from canola oil, emulsified with 5vol% and 10vol%of water. In order to prepare the emulsified fuel, two different types of emulsifiers, Sorbian Monooleate (Span 80) and Polyoxymethylene Sorbian Monooleate (Tween 80), were used. The engine was operated at three different speeds 1000, 2100 and 3000 rpm and at each speed, three loads were applied: low (≈20%), medium (≈50%) andhigh(˃80%).Properties such as density, viscosity and calorific value of emulsified fuel were measured. Brake thermal efficiency (BTE) and brake- specific energy consumption(BSEC) were tested as the performance parameters. Regulated emissions carbon monoxide (CO), hydrocarbon (HC), oxides of nitrogen (NO x ) and smoke were measured. Performance and emissions of emulsified biodiesel were compared to that of petroleum diesel. Improved NO x and smoke were achieved by using emulsified biodiesel over diesel.
