Exhaust, Pollution and West Virginia

Study finds high exhaust temperatures within NTE operation for heavy-duty diesels with aftertreatment systems contribute to high nanoparticle concentrations

The transient results illustrate the gradual formation of the nucleation mode particles with continuous increase in exhaust temperatures. Diesel particulate filters (DPF) and urea-based selective catalytic reduction (SCR) exhaust after-treatment systems thus have emerged as feasible strategies to meet the 2010 USEPA regulations.

The International Council on Clean Transportation (ICCT) contracted with the Center for Alternative Fuels, Engines and Emissions at West Virginia University to conduct in-use testing of three light-duty diesel vehicles (two 2.0L diesels and one 3.0L diesel) over pre-defined test routes exhibiting diverse driving conditions.

The Clean Air Act requires vehicle manufacturers to certify to EPA that their products will meet applicable federal emission standards to control air pollution, and every vehicle sold in the US must be covered by an EPA-issued certificate of conformity. The software produced by Volkswagen is a “defeat device,” as defined by the Clean Air Act.

The gas is first cooled to condense and remove moisture and residual pollutants before it enters the CO 2 absorber. The entire extracted gas volume then is reintroduced into the FGD outlet transition duct where it is mixed with the FGD exhaust gas. The three-step carbon capture process at Pleasant Prairie.

ICCT study finds real-world NOx emissions from Euro 6 diesels ~7x higher than Euro 6 regulatory levels

The study is based on on-road tests of 15 vehicles—12 certified to the Euro 6 standard and three to the US equivalent (Tier 2 Bin 5) using Portable Emissions Measurement Systems (PEMS), which provide a continuous stream of vehicle data signals including emission rates, velocity, acceleration, road gradient and exhaust temperature.
