Study finds propane school buses significantly decrease NOx emissions compared to diesel

Green Car Congress

The study was conducted in 2018 by West Virginia University’s Center of Alternatives Fuels, Engines, and Emissions (CAFEE). West Virginia University’s Center for Alternative Fuels Engines and Emissions (CAFEE) completed two types of tests at different times of the year during 2018 on four Blue Bird school buses.

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

Green Car Congress

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 entire extracted gas volume then is reintroduced into the FGD outlet transition duct where it is mixed with the FGD exhaust gas. As the next step in demonstrations of increasing size, the first of two product validation facilities recently began at the American Electric Power (AEP) Mountaineer Plant in New Haven, West Virginia.

ICCT-sponsored study of in-use testing of 3 Tier2-Bin5, CA LEV-II light-duty diesels finds wide variation of emissions against the limits

Green Car Congress

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.

UCLA, ARB, WVU measure on-road particle numbers for heavy-duty diesel and CNG trucks in California

Green Car Congress

In a new study, a team from UCLA, with colleagues from the California Air Resources Board (ARB) and West Virginia University, measured total particle number emission factors (PNEFs) from six newly certified heavy-duty vehicles (HDVs) powered by diesel and CNG totaling over 6,800 miles of on-road operation in California.
