CORTEA: Analysis of Pollutant Emissions in Light Vehicles
CORTEA : measuring pollutant emissions on light vehicles
PROBLEM Vehicle emissions, while largely regulated for certain gases such as NOx and CO2, do not take into account a large number of unregulated pollutants that are just as harmful to health and the environment. Volatile organic compounds (VOCs), sulfur compounds, aromatic hydrocarbons (such as toluene and benzene), as well as products such as formaldehyde and formic acid, are neglected by current standards. Yet these substances have a significant impact on air quality, and measuring them is crucial to establishing future, stricter regulations in the automotive sector.
CRMT SOLUTION As part of the CORTEA project, partly funded by ADEME, CRMT is developing an innovative solution to address this issue: an on-board FTIR (Fourier Transform Infrared Spectroscopy) analyzer capable of simultaneously measuring regulated pollutants (NO, NO2, CO, CO2, THC, NH3) as well as non-regulated pollutants such as VOCs, sulfur compounds, and various cyclic and aromatic compounds. Unlike current PEMS analyzers, which are compact but not on-board, this FTIR analyzer is designed to be integrated directly into vehicles for real-time measurements during real-life driving cycles (RDE) on diesel, gasoline and natural gas vehicles.
THE PLUS Thanks to this cutting-edge technology, CRMT is once again demonstrating its ability to innovate in the measurement of pollutant emissions. The results obtained from these measurements will contribute directly to the definition of new vehicle certification criteria, thus influencing future environmental standards in the automotive sector. This project will broaden the scope of current regulations, by including pollutants that were previously ignored, but which are critical for public health and environmental protection.
