“…The diesel particulate filter (DPF) model simulates the filtration and pressure drop behavior as well as the thermal and catalytic regeneration of the filter. The model has been presented and validated in numerous previous publications. − It solves the transient mass, momentum, species, and energy balances in the channels of after-treatment devices, accounting for the catalytic surface reactions. axisuite uses differential and algebraic equations for the heat and mass transfer in the converter and is equipped with intralayer washcoat discretization to account for the coupling between reaction and diffusion phenomena.…”

Hybridization offers great potential for decreasing pollutant and carbon dioxide emissions of diesel cars. However, an assessment of the real-world emissions performance of modern diesel hybrids is missing. Here, we test three diesel-hybrid cars on the road and benchmark our findings with two cars against tests on the chassis dynamometer and model simulations. The pollutant emissions of the two cars tested on the chassis dynamometer were in compliance with the relevant Euro standards over the New European Driving Cycle and Worldwide harmonized Light vehicles Test Procedure. On the road, all three diesel-hybrids exceeded the regulatory NO limits (average exceedance for all trips: +150% for the Volvo, +510% for the Peugeot, and +550% for the Mercedes-Benz) and also showed elevated on-road CO emissions (average exceedance of certification values: +178, +77, and +52%, respectively). These findings point to a wide discrepancy between certified and on-road CO and suggest that hybridization alone is insufficient to achieve low-NO emissions of diesel powertrains. Instead, our simulation suggests that properly calibrated selective catalytic reduction filter and lean-NO trap after-treatment technologies can reduce the on-road NO emissions to 0.023 and 0.068 g/km on average, respectively, well below the Euro 6 limit (0.080 g/km).
