This research presents the differences between the exhaust emission parameters when biodiesel and biodiesel blends are used instead of Ultra-Low Sulfur Diesel (ULSD). Measurements have been conducted on three commercial light-duty engines. The engines include an Audi 1.9 TDI that lives up to the requirements of Euro 2, a Peugeot 1.6-liter common rail with original oxidation catalyst and EGR that lives up to the requirements of Euro 4 and a Peugeot 1.6-liter common rail with original Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) that lives up to the requirements of Euro 4. Tests were performed on a dynamometer running steady state in five representative modes drawn from the ISO 8178 test procedure. The reference diesel was in accordance with EN 590. The biodiesel blends are based on a new EN 14214 animal fatty acid methyl ester (AFME).
