The study was conducted in 2018 by WestVirginia University’s Center of Alternatives Fuels, Engines, and Emissions (CAFEE). WestVirginia 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.
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.
A number of research groups have explored the development of a free-piston linear generator, including work at WestVirginia University (WVU), Sandia National Laboratory (SNL), Chalmers University of Technology ( earlier post ), and Shanghai Jiaotong University ( earlier post ), among others. —Ling Huang 2012.
A number of groups have recently or are currently investigating the use of free piston engine power generation applications with a focus on automotive, including academic work at WestVirginia University (WVU), Sandia National Laboratory (SNL), Chalmers University of Technology (Sweden), and Shanghai Jiaotong University. Scavenging.
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, WestVirginia.
The International Council on Clean Transportation (ICCT) contracted with the Center for Alternative Fuels, Engines and Emissions at WestVirginia 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.
In a new study, a team from UCLA, with colleagues from the California Air Resources Board (ARB) and WestVirginia 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.
Ultra-High Temperature Anode Recycle Blower for Solid Oxide Fuel Cell Mohawk Innovative Technology aims to develop an oil-free anode recycle blower capable of using uncooled SOFC exhaust gas directly at temperatures up to 700 °C. WestVirginia University. DOE: $299,055; Non-DOE: $74,764; Total: $373,819.
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.
Breeding High Yielding Bioenergy Sorghum for the New Bioenergy Belt Clemson University, along with the Carnegie Mellon Robotics Institute and partners, will phenotype an exhaustive set of international germplasm and plant varieties. WestVirginia University Research Corporation. Clemson University. Tour Engine. Earlier post.)
WestVirginia University. WestVirginia University (WVU) will develop a new class of ultra-high temperature Refractory Complex Concentrated Alloys-based Composites (RCCC) for high temperature applications such as combustion turbines used in the aerospace and energy industries.
WestVirginia University Research Corporation. valve faces, piston crowns, and exhaust ports) to improve fuel economy. Develop advanced solutions for Class 7 and Class 8 heavy‐duty vehicles that eliminates or mitigates the negative effects of current diesel exhaust after‐treatment equipment systems on dual fuel trucks.
VW engineers believed the increased stress on the exhaust system from being driven in the “dyno mode” could be the cause of the hardware failures. With these alterations, it was believed the stress on the exhaust system would be reduced because the engine would not be operating for as long in “dyno mode.”
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.
