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

In a study published in the ACS journal Energy & Fuels , a team from the University of Vermont reports that particulate matter from the combustion of biodiesel blends may be 50–80% less toxic per unit PM mass emitted than PM from petroleum diesel, depending on feedstock. PM-normalized DTT Activity for biodiesel exhaust PM. to 13.6 ± 3.8

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

Green Car Congress

EGR improved both Brake Specific Fuel Consumption (BSFC) and Brake Thermal Efficiency (BTE) for the studied fuels with respect to baseline conditions. Their paper is published in the journal Fuel. On the other hand, GDI engines have reported to increase the concentration of the Particulate Matter (PM) emissions.

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.

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

Green Car Congress

Their study was published online 21 December in the ACS journal Energy & Fuels. MJ/kg vs 43 MJ/kg) brake-specific fuel consumption (BSFC) increases to attain the same power level. L inline six-cylinder turbo-diesel outfitted with common rail fuel injection, externally cooled EGR, and VGT.
