5. General conclusion

Since each manufacturer has its own customer targets, vehicle design choices and industrial strategy, a single optimal aftertreatment solution applicable to all vehicles is not realistic. This has led to the emergence of different configurations of pollution control systems, depending on the manufacturer and range targeted.

The final step in the design process for a pollution control system is to identify the possibilities for compacting the device to create multi-functional systems that keep size and footprint (and, if possible, cost) under control.

Once the quality of the fuels and lubricants has been adjusted, the quality of the catalytic post-treatment relies on the design of the catalyst and, more specifically, its formulation. The "catalytic design" approach is complex and multifaceted. Just as there is no single type of engine, there...
