Study finds clear trend of increasing NOx with higher biodiesel blends with CARB diesel; NOx neutrality achieved by blending in renewable or GTL diesel

Green Car Congress

NO x emissions results of biodiesel, renewable, and GTL diesel fuel blends, and CARB diesel fuel for 2006 Cummins ISM. They also found that increasing renewable diesel (Neste Oil’s NExBTL) and gas-to-liquids (GTL) diesel blends showed NO x reductions with rising blend level. Credit: ACS, Hajbabaei et al.

Study finds butanol-gasoline blends effective to control soot from CI engines under Low Temperature Combustion

Green Car Congress

A study by a team at Tianjin University found that the addition of n-butanol to gasoline for use in a compression ignition engine (CI) under Low Temperature Combustion (LTC) conditions has a significant effect on soot reduction. Renewable feedstock and high octane number rating make ethanol a very promising alternative fuel in CI engine.
