Study finds total PM10 emissions from EVs equal to those of modern ICEVs; role of weight and non-exhaust PM

Green Car Congress

A new study by a team from the University of Edinburgh and independent engineering company INNAS BV has found that, when factoring in the additional weight and non-exhaust PM factors, total PM 10 emissions from electric vehicles (EVs) are equal to those of modern internal combustion engine vehicles (ICEVs).

SwRI CAT-DEF reduces heavy-duty diesel emissions to meet CARB 2027 NOx requirements

Green Car Congress

CAT-DEF—Catalyzed Diesel Exhaust Fluid—is an SwRI-developed catalyst- and surfactant-modified diesel exhaust fluid (DEF) solution. urea-water solution—is injected into the exhaust stream and ideally decomposes to form ammonia, which reacts with NO x on the SCR catalyst to form N 2 and H 2 O. DEF—a 32.5

Westport Fuel Systems & AVL conclude high-efficiency H2 powertrain can outperform fuel cells in TCO for heavy-duty applications

Green Car Congress

In a joint publication, WFS and AVL conclude that the combined high efficiency and lower system costs relative to FCEVs make H 2 -HPDI the most capital efficient means to use hydrogen and lower CO 2 emissions near-term and that it has the potential to remain competitive with fully industrialized FCEV in the future.
