Performance of scaled-up sulphur traps on a diesel vehicle

Developed sulphur traps were investigated on a diesel vehicle regarding the protection of a NOx storage/reduction catalyst.

Durability tests of SOx traps and NOx trap in combination with state-of-the-art and the two new developed SOx traps were performed. For the bench-scale tests a 1.9l 74kW VW TDI Touran was used.

In the bench-scale tests the vehicle is operated for 15.000 to 20.000km in a dynamic cycle at the velocities of 50, 70 and 100km/h. Experiments at 10ppm and 30ppm S fuel were made, but in the first case the deactivation was too slow.
