Study finds biodiesel blend reduces total particle mass in emissions but may have greater adverse health effect per mass than diesel

Green Car Congress

They found that total particulate gravimetric mass collected over the engine test cycle was more than 2 times higher for B0 than for B20 fuel. Particle number distributions aggregated over one example drive cycle indicate a unimodal B0 distribution centered at 51 nm, but a B20 distribution with a smaller diameter mode at 32.2

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

Green Car Congress

The researchers analyzed samples of PM obtained from light-duty diesel engine transient cycle emission tests with two biodiesel feedstocks—soybean (SOY) and waste vegetable oil (WVO)—blended with ultralow sulfur petrodiesel at five different volume percentages of biodiesel, Bxx (B0, B10, B20, B50, and B100).

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

Green Car Congress

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. 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.

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

Green Car Congress

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). However, NO x emissions were higher, and the engine thermal efficiency was slightly lower with higher JBD blends. Compared to FT fuel, higher JBD blends showed higher BSFC and lower thermal efficiency.

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

Green Car Congress

The 33% v/v butanol-gasoline fuel was blended at the University of Birmingham using standard EN228 gasoline with 5% (v/v) ethanol content (B0) and pure n-butanol. They found that the influence of the butanol depended on engine load. At low loads, butanol’s physical properties (e.g. higher flame speed).

Massachusetts to Accept Only Waste-Derived Biofuels to Qualify for Mandate for Diesel and Home Heating Oil

Green Car Congress

Compliance Entities (petroleum terminal operators that supply heating oil and diesel fuel consumed in MA) will have to report sales of heating fuel oil, diesel fuel, non-qualified biodiesel content in all shipments received (B0-B5 levels), and Qualified Advanced Biodiesel volume sold (gallons sold by each supply source) for Early Action Credit.

QuantumScape delivers Alpha-2 solid-state prototypes to EV automakers, moving closer to commercialization

Baua Electric

QuantumScape explained that the Alpha-2 prototype cells act as a bridge between the A0 and QSE-5 B0 prototypes Sivaram mentioned above. We are very encouraged by the initial Alpha-2 performance results and excited about the first QSE-5 cells we expect to manufacture later this year.
