SEAT pushes forward with CNG line-up

Green Car Congress

A CNG vehicle reduces CO 2 emissions by about 25% compared to a gasoline-driven equivalent. Only a pure electric vehicle running on 100% renewable energy would offer a better overall outcome. But even in the event of using the gasoline tank, the switch is so seamless that the driver is unlikely to notice.

Bosch says it has solved diesel NOx problem; as low as 13 mg NOx/km even under RDE; refining existing technologies

Green Car Congress

But even today, vehicles equipped with Bosch diesel technology can achieve as little as 13 milligrams of NO x in standard legally-compliant RDE cycles. A dynamic driving style demands an equally dynamic recirculation of exhaust gases. To ensure optimum NO x conversion, the exhaust gases must be hotter than 200 degrees Celsius.

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.
