CPT, TU Wien study finds 48V mild diesel hybrid cuts engine-out NOx 9%, 4.5% fuel economy improvement

Green Car Congress

The cost effectiveness of this approach is further underscored by its impact on lean NO x trap (LNT) and selective catalytic reduction (SCR) aftertreatment systems, which have less raw NOx emissions to process, potentially allowing for a reduction in exhaust system cost and complexity, and a longer service life. —Paul Bloore.
