European market surveillance of motor vehicles - Altitude Simulation Dataset

This dataset was produced by the JRC while conducting the very first experiments with an Altimetric Constant Volume Sampler. This system simulates driving at different altitudes through changes of ambient temperature, humidity and pressure conditions at the vehicle’s engine air intake and tailpipe. It aims at increasing the technical capacity of the JRC to strengthen its tasks within the market surveillance of light-duty vehicles according to Regulation (EU) 2018/858. This new facility will support the verification of the environmental performance of light-duty vehicles, and the identification of Auxiliary Emission Strategies (AES). This dataset includes the emission results from the testing of three vehicles featuring different engine technologies.
