Description: This image shows a Fourier transform infrared spectroscopy (FTIR) chamber, where a laser light is used to probe the chemical makeup of engine exhaust gases generated in Pacific Northwest National Laboratory's Engine Emissions Laboratory. The chemistry of engine exhaust is complex; it changes with driving conditions and depends greatly on the type of engine and fuel used. Understanding the chemistry may unlock ways to reduce engine emissions and help the environment.
