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

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

Green Car Congress

viscosity and heat of vaporization) resulted in a negative impact on carbon monoxide emissions at low load due to combustion inefficiencies. 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. higher flame speed).

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.

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

Green Car Congress

Low Carbon Fuel Standard. The state Department of Energy Resources has authority to delay the minimum content requirements if there are no biofuels available that meet those standards. DOER will announce by 31 December 2010 whether the second-year Biofuels Mandate will be at the 2% or 3% level.
