Center for Alternative Fuels, Engines, and Emissions

Researchers in our Department of Mechanical and Aerospace Engineering's Center for Alternative Fuels, Engines, and Emissions (CAFEE) have built an internationally recognized research program aimed at reducing exhaust emissions and consumption of petroleum-based fuels. CAFEE's focus is on heavy-duty vehicles such as trucks, buses, locomotives, and ships, where improvements have traditionally lagged behind lighter-duty vehicles.

CAFEE has some of the nation's most extensive experience in measuring exhaust emissions from conventionally and alternatively-fueled, heavy-duty vehicles. Founded in 1989, CAFEE conducts approximately $5 million per year in research, with funding from the U.S. Departments of Energy and Transportation, and from companies, states and municipalities around the nation.

CAFEE offers the unique ability to travel throughout North America to conduct emissions testing, thanks to its three Transportable Vehicle Emissions Testing Laboratories, including a new low-emissions measurement laboratory.
