Projected conditions for internal combustion engines in 2025 push light-duty engine exhaust temperatures into the low end of gas turbine regimes, Haynes said. The increasing piston, cylinder, head, exhaust valve and turbocharger temperatures represent significant structural materials—and cost—challenges.

The smaller size enables better heat management and retention for improved fuel economy capability, while the simple single-pass exhaust flow design delivers low back pressure, meeting the needs of end-user customers. A typical filter consists of an array of small channels for exhaust gas to flow.

Since 2017, European legislation has required that new passenger car models tested according to an RDE-compliant mix of urban, extra-urban, and freeway cycles emit no more than 168 milligrams of NO x per kilometer. A dynamic driving style demands an equally dynamic recirculation of exhaust gases. —Bosch CEO Dr. Volkmar Denner.

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.

This is a voluntary and early improvement towards the RDE (Real Driving Emissions) legislation that goes into effect in Europe in 2017. The events and discussions in the last weeks and months have shown that there is a tremendous focus on the automotive industry and it is now time to act based on the learnings. SCR technology.
