CAFEE

Center for Alternative Fuels Engines and Emissions

Engines and Emissions
Research Laboratory

Located on West Virginia University's Evansdale Campus, the Engines and Emissions Research Laboratory is CAFEE's primary research facility. The main thrust of this laboratory is to perform emissions research for heavy-duty engines fueled from diesel or natural gas.

While the majority of the work performed in the EERL has historically involved on-road, diesel engines with a power range of 150 horsepower to 700 horsepower, the laboratory is capable of measuring raw and dilute emissions for a wide range on engines and fuels. Previous projects have involved engines as small as 1 horsepower and as large as 1000 horsepower, operating on fuels from standard commercially available gasoline and diesel, to natural gas, propane, methanol, di-methyl ether and a multitude of alternative fuels.

The facility houses two constant volume sampling full-flow dilution tunnels and two independent emissions measurement systems, as well as several engine dynamometers. The laboratory is configured to perform the full spectrum of dynamometer tests: EPA transient certification emissions tests, steady-state tests such as the Supplemental Emissions Test and Ramped Modal Cycle and simulated in-use cycles tests. Regulated emissions from these tests are measured following 40 CFR Part 1065, Part 1066 and Part 86 Subpart N. All tests are performed following 40 CFR with the exception of California testing, which is performed under the California Code of Regulations Title 13.
