The last few years of the automotive industry were marked by the exhaust gas scandal, which is still in full legal process. The effects are long-term and sustainable. The positive aspect is that the vehicles will be much cleaner and more environmentally friendly in real operation, even in colder weather. This has its price, in particular the diesel exhaust aftertreatment becomes considerably more complex and combines more and more often the systems of NOx storage catalytic converter and SCR denitrification. This cannot hide the fact that the reputation of diesel engines among end users is permanently damaged. The consequence is a further reduction in the proportion of diesel. This has a massive impact on exhaust system manufacturers and the corresponding sensors. These influences and future trends will be highlighted at the international conference “Aftertreatment & Sensors” in Munich in September 2019.
Now that the problems of exhaust aftertreatment are largely under control, the Euro 7 is imminent. It is to be expected that the nitrogen oxide limits will be further lowered. China is a trendsetter with 35 mg NOx/km. In Europe, even stricter 30 mg NOx/km are already being discussed. Furthermore, trace gases are increasingly coming into the focus of legislators. Limits for ammonia, ethanol, nitrous oxide and formaldehyde have now also become conceivable in Europe.
A contribution from the Federal Environment Agency will deal with future emission limits. An even greater challenge for engine manufacturers lies in the CO2 problem. Almost unnoticed by the population, the introduction of limit values for heavy commercial vehicles is a small revolution. A member of the European Commission explains what this will look like. The changed laws are shifting the market for exhaust system components. The market research company IHS Global examines the market for exhaust gas sensors. CPK Automotive has developed new approaches to NOx sensors for the NRMM segment. To this day, the exhaust masses are determined by calculation. A hot-film anemometer opens up new perspectives for use in exhaust gas recirculation and as a flowmeter in PEMS […]
The conference gives these approaches a much-noticed platform. The organizers of the conference are careful to give space to the full range of developments in exhaust gas purification and sensor technology. Thus, this annual conference is an independent reflection of current topics. Between the lectures and at the evening event there will be enough time for intensive networking.
