The main conclusions of the report include: Compared to emission controls on MY 2010 US diesel trucks, today’s compact aftertreatment systems are 40% lighter, 60% smaller, and substantially less expensive. This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010.

Theoretically, cars operating on higher ethanol blends than the design point could emit greater concentrations of pollutants in exhaust gas. In the cylinder where combustion takes place, the fuel evaporates before it is burned, and this evaporation helps cool off the air/fuel mixture and exhaust gas. 25% E85 in 2022.
