A single cylinder direct injection diesel engine was fuelled with blends of biodiesel and diesel at different proportions. The engine performance and emission characteristics were determined. The engine NOX emission was noted to be higher than the diesel fuel operation with all blends. Diethyl ether was then added at different proportions to the blends. The addition of diethyl ether to the blends reduced the NOX emission at low and medium loads; however, at high loads the NOX emission was higher compared to diesel and lower compared to the corresponding biodiesel blend. The addition of diethyl ether to biodiesel blends reduced the both NOX and smoke emission further.
