Summary

This paper describes the implementation of an advanced emission control system on a gasoline demonstrator vehicle and the validation of the ultra-low pollutant emissions on sustainable renewable fuels. The gasoline demonstrator vehicle is equipped with a 48 V mild-hybrid powertrain with a turbocharged 1.5 l direct injection engine. The emission control system consists of a three-way catalyst (TWC) in close-coupled position, in combination with an underfloor catalysed gasoline particulate filter (cGPF), a second TWC and an ammonia slip catalyst (ASC). In a second phase, an electrically heated catalyst (EHC) is included as the first part within the close-coupled TWC.

The first part of the paper on pollutant emissions investigates the potential of the emission control system to reduce the initial cold-start emissions directly after engine start and the operation strategy of the ASC for a gasoline application. In addition to regulated pollutants, currently non-regulated emissions of PN10, NH3 and N2O are measured. Pollutant emission tests are conducted over a variety of conditions, beyond the Euro 6d RDE boundary conditions. This paper presents ultra-low pollutant emissions measured on an exemplary RDE aggressive test on the chassis dyno at ambient temperatures of 23 °C and -10 °C.
