Internal Combustion Engines Laboratory

Research in the Internal Combustion Engines Laboratory includes projects ranging from ammoniacombustion experiments to experiments using alternative fuels in compression ignition engines that have been funded by private industry and the federal government. The laboratory contains a large engine test cell capable of testing medium-duty engines. Representative engines in the lab are a Cummins 4BT3.9 turbocharged engine and a General Motors Quad-4 fuel injected engine. The lab houses a state-of-the-art emissions sampling system, consisting of CO, CO2, NOx, NH3, O2, SO2, and hydrocarbon analyzers.
