High-Accuracy Emissions Measurement
The future of engine emissions measurement must account for more innovative after treatment devices, the introduction of alternative fuels, and the ability to simultaneously measure a multitude of different gas components. Over the last decades conventional analyzer systems have been tailored to measure regulated gases. Adding the ability to measure non-regulated gases is difficult and expensive. Portable Emission Measurement Systems (PEMS) are similar to conventional analyzer systems, but as these systems are used under real-world conditions, they are exposed to vibrations caused by theroads or the terrain on which the vehicle is tested. In order to overcome the vibration issues, most of these systems use garage-type NDIR analyzers for CO measurements, limiting the ability to accurately measure low CO concentrations. For measuring NO/NO2, PEMS usually utilize NDUV=type analyzers that use a completely different measurement principle than the commonly-used CLDs.
A&D Technology’s highly accurate FTIR systems are the ideal solution for today’s and future emissions testing requirements, specifically addressing all of these concerns by:
- Using identical technology for measuring exhaust emissions in the test cell environment or under real-world conditions
- Measuring up to 40 gases simultaneously with one detector
- Providing optimized gas analysis methods for different fuel types, including Gasoline, Diesel, CNG and other alternative fuels
