“…no exhaust flow rate effect was considered), the values found were in agreement with what could be observed with production sensors in the literature. 73 Furthermore, the aim of these delays in this specific case is not to represent precisely the dynamics of the system, but instead to ensure that the levels of N O x that will be averaged for the steady-state point do not suffer from high range and bias due to ongoing transient behavior. While this might still introduce some variation, owing to the difficulty to find proper steady-state and steps operation for sensor characterization in real-driving data, these empiric delays were regarded as adequate for this detection method.…”

As type approval driving cycles were found to be insufficient to represent the real impact of emissions from on-road vehicles, it became clear that real-driving emissions must be considered to effectively address the current transportation challenges. The expected introduction of on-board emission monitoring is believed to require tools that will evaluate the on-road emissions conformity of vehicles over their lifetime. In this regard, the significant amount of data made available from modern vehicles opens for improved emissions prediction and diagnostics opportunities. This article explores therefore the effectiveness of predicting instantaneous engine-out [Formula: see text] emissions given in-service vehicle data alone. To this end, a 9 months daily vehicle usage database was used to calibrate and evaluate a semi-empirical [Formula: see text] emission model and the results showed good agreement with measurements provided by the production sensor. This approach offers a tool for simulating real-driving engine-out [Formula: see text] emissions that could help to comply with emission standards by feeding and updating advanced emissions control strategies.
