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.

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.

EPA and California ARB charge Volkswagen with using software defeat device to circumvent NOx testing in 4-cylinder 2.0L diesels

Green Car Congress

This special cycle revealed that VW’s recall calibration did increase Diesel Exhaust Fluid (DEF) dosing upon initial startup; however, dosing was not sufficient to keep NO x emission levels from rising throughout the cycle. This resulted in uncontrolled NO x emission despite the SCR reaching sufficient operating temperatures.
