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. nmol/min/mg PM for B0 and B100, respectively, and from 22.6 ± 4.5

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.
