Study finds PM from biodiesel blends may be 50-80% less toxic per unit PM mass than from petroleum diesel

Green Car Congress

OP in oxidized aerosols, including engine exhaust, is commonly quantified using the DTT (dithiothreitol) assay. nmol/min/mg PM for B0 and B100, respectively, and from 22.6 ± 4.5 In the study, the team examined the relationships between biodiesel fuel blend, exhaust particle oxidative potential (OP), and PM composition. to 13.6 ± 3.8

Birmingham study finds butanol-gasoline blend reduces GDI engine-out carbonaceous emissions; similar NOx

Green Car Congress

A team at the University of Birmingham reports that a blend of 33% v/v of butanol in EN228 commercial gasoline containing 5% of ethanol (B33) reduces GDI (gasoline direct injection) engine-out carbonaceous emissions, while maintaining similar levels of NO x emissions when compared to standard gasoline combustion at low and medium engine loads.

AvtoVAZ launches 3 concepts at Moscow Motor Show; collaboration with Renault-Nissan

Green Car Congress

LADA Vesta, based on a new Russian platform B/C and developed by AvtoVAZ engineers in collaboration with the Renault-Nissan Alliance, will be produced in Izhevsk, Russia starting fall 2015. LADA XRAY, a hatchback SUV based on the B0 platform, was developed by AvtoVAZ stylists while its body was developed jointly by Renault and AvtoVAZ.

Jatropha Biodiesel-FT Blends Reduce Most Criteria Pollutants Compared to Neat FT; Higher NOx

Green Car Congress

However, NO x emissions were higher, and the engine thermal efficiency was slightly lower with higher JBD blends. The authors tested JBD blended with FT fuel in volumetric ratios of 0:100, 25:75, 50:50, 75:25, and 100:0 (B0, B25, B50, B75, and B100). Energy Fuels , 24 (5), pp 2868–2874 doi: 10.1021/ef901317u.

Optimizing Turbo Diesels for Emissions and Performance with 5% and 20% Biodiesel Blends

Green Car Congress

When used in diesel engines, biodiesel usually exhibits several combustion-related advantages, including reductions in CO, UHC and PM emissions, as well as a net CO 2 reduction. The engine used in the study was a 2007 Cummins ISB 6.7 Their study was published online 21 December in the ACS journal Energy & Fuels.
