Light-Duty Vehicle Emissions

The Light-Duty Vehicle Emissions Section in the Engine, Emissions and Vehicle Research Division at Southwest Research Institute (SwRI) conducts research and development on emissions from passenger cars and light trucks, specifically as affected by conventional fuel composition, or the replacement of conventional fuels by alternative fuels such as natural gas, LPG, and alcohols. In addition, the section performs detailed exhaust characterization such as hydrocarbon speciation, measurement of air toxics, and sampling and analysis of particulate matter. Evaporative as well as tailpipe emissions are measured. Test cycles include those required by the Environmental Protection Agency (EPA) and California Air Resources Board (CARB), as well as the ECE and Japan. Off-cycle conditions (hard accelerations, high power absorption, and others) can be run, and test temperatures can be controlled from 10 °F to 120 °F (-12 °C to 49 °C).
