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.

Polycyclic aromatic hydrocarbons (PAHs) and nitrated PAHs were quantified in both the vapor and particle phases of the PM, with the GPF-equipped vehicles practically eliminating most of these species in the exhaust. The rapid market penetration of GDI vehicles has led governments to impose stricter standards to control PM emissions.

A study by a team from North Carolina State University, with colleagues from the Urban Air Initiative and 3DATX Corporation, has shown that non-FFVs (flexible-fuel vehicles) can adapt to a mid-level ethanol blend—specifically E27. The modes were then weighted according to real-world standard driving cycles.

Traffic contributes more to NO x emissions in Europe than previously thought, according to a new study by a team at the University of Innsbruck. Generally, different combustion and exhaust treatment characteristics result in significantly higher NO x /CO 2 emission ratios for diesel powered cars than for gasoline.
