Abstract:
This study is focused on second generation biodiesel obtained from palm oil fatty acid distilled (PFAD) and Used Cooking Oil (UCO) blended with EN 590 diesel and heating oil, to verify the effects on particulate and gaseous exhaust emissions of a light commercial vehicles (LCV) fleet composed of one Euro 3, one Euro 4 (without DPF) and one Euro 5b LCV and small heating boilers used for residential heating. Vehicles without DPF showed a slight decrease, by increasing the biodiesel content, for the soot fraction and for total particle number emissions. Euro 5 showed lower differences than the other two LCVs about particulate emissions, due to DPF efficiency hiding the emission reduction effect of the biodiesel fraction. Two boilers were fed with pure biodiesel and heating oil/biodiesel blends, showing a decrease of nano-particulate and PAHs emissions, increasing the biodiesel content, using both second-generation biofuels. The biodiesel from PFAD showed a better emission performance blended with the heating oil, and its use as B100 fuel was more difficult due of its high pour point that does not facilitate the feeding of the boiler above all in the winter months. The study confirms the effectiveness of second-generation biodiesel blends in reducing pollutants emissions from pre-Euro 6 LCVs and heating boilers.
