Virginia Tech team developing intelligent wearable analyzer for pollutants in transportation-related workplaces

Green Car Congress

Truck drivers have a higher risk of lung cancer that is associated with exposure to diesel exhaust. Diesel exhaust is a complex mixture of particles and gases and the specific component responsible for health effects has not been identified. Some of the gaseous compounds are known or suspected carcinogens.

U. Houston-led project looking for new exhaust treatment catalysts for low-temperature lean-burn combustion engines

Green Car Congress

million project to find new catalytic materials that work at lower exhaust temperatures, allowing automakers to build vehicles that operate more efficiently while retaining the ability to clean emissions before they leave the tailpipe. Catalytic converters clean vehicle exhaust into nitrogen, water and carbon dioxide.

No More Leg Day: South Carolina Squat Ban Goes Into Effect Soon

The Truth About Cars

South Carolina now joins North Carolina, Tennessee, and Virginia with the ban. People still alter diesel trucks to “roll coal,” and loud exhausts – not always a bad thing – remain a problem for some communities.

NSF and DOE Award Virginia Tech $1.5M for Thermoelectric Materials Work

Green Car Congress

A team of Virginia Tech engineers has received a three-year, $1.5 These new materials will be integrated into optimized heat exchanger modules that will extract heat from the vehicle exhaust, allowing for the thermoelectric materials to generate useful electric power from energy in the exhaust that currently is wasted.

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.

NASA selects four university teams for aviation projects; eliminating emissions and autonomy research

Green Car Congress

The team will explore using liquid ammonia as fuel for a jet engine and generating electricity from the engine’s exhaust heat, reducing emissions, and saving on fuel. The four teams and their research topics are: University of Central Florida. University of Illinois, Urbana-Champaign.
