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

viscosity and heat of vaporization) resulted in a negative impact on carbon monoxide emissions at low load due to combustion inefficiencies. EGR improved both Brake Specific Fuel Consumption (BSFC) and Brake Thermal Efficiency (BTE) for the studied fuels with respect to baseline conditions. higher flame speed).

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

Green Car Congress

Blending jatropha biodiesel (JBD) with Fischer-Tropsch synthetic diesel (FT) results in lower CO, THC, smoke and PM emissions compared to neat FT, according to a study by researchers at the Norwegian University of Science and Technology (NTNU) published in the ACS journal Energy & Fuels.

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

Green Car Congress

For consideration as a qualifying fuel, the waste-derived biofuel must yield a 50% greenhouse gas reduction threshold required in the Massachusetts law as determined by a preliminary analysis based on both CARB and EPA methodologies. Massachusetts was the first state in the nation to require biofuel in home heating fuel.
