Identifying high-emitting Euro 7 vehicles with the NOx-to-fuel mass ratio
[EN] This paper examines the introduction of the NOx-to-fuel mass ratio in the Euro 7 regulation, a parameter designed to evaluate the effectiveness of the vehicle emission control by assessing the mass of NOx emitted relative to fuel consumption. This approach has been selected for its potential to...

| Sumario: | [EN] This paper examines the introduction of the NOx-to-fuel mass ratio in the Euro 7 regulation, a parameter designed to evaluate the effectiveness of the vehicle emission control by assessing the mass of NOx emitted relative to fuel consumption. This approach has been selected for its potential to identify high-emitting vehicles, which may result from malfunctioning or manipulated emission control systems. This study reviews in detail the methodology proposed by the European Commission for this parameter utilizing data from an on-road Euro 6d-Temp diesel vehicle, anticipating its outcomes within the Euro 7 framework and highlighting some potential limitations. |
