The growing environmental concerns and the depletion of petroleum reserves have caused the development of alternative fuels. Biodiesel and alcohols are receiving increasing attention as alternative fuels for diesel engines due to well oxygenated, renewable fuels. In this study, a single cylinder, naturally aspirated, direct injection diesel engine has been experimentally investigated using ethanol-blended waste cooking oil methyl ester. Various proportion of biodiesel-ethanol blends were used in stability test at the different temperatures from 10 °C to 40 °C in the increment of 10°C. Based on the stability tests and improvement in fuel properties, B90E10 (90% biodiesel and 10% ethanol) and B80E20 (80% biodiesel and 20% ethanol) were selected for this investigation. Test results revealed that the improved engine characteristics with the use of B9E10 especially in comparison with B80E20. Reduction in brake thermal efficiency by 3.8% and slightly higher brake specific energy consumption of 15.1% were observed with B90E10 when compared to diesel at 100% load condition. Carbon monoxide, unburnt hydrocarbon, nitric oxide and smoke emission of B90E10 were reduced by 0.09% by vol., 10 ppm, 187 ppm and 12.9%, respectively compared to diesel. B90E10 exhibited lower peak pressure of 70.5 bar, slightly longer ignition delay of 14.2 °CA, and combustion duration of 43.3 °CA was also observed at 100% load condition.
