Fehlerbetrachtung bei der Messung von Gastemperaturen

In den letzten Jahren wurden auf dem Gebiet der Abgasreinigung dominante Fortschritte erzielt. Infolge der sich weltweit verscharfenden Abgasgrenzwerte mussen die Abgasemissionen zukunftig noch weiter gesenkt werden. Der Weiterentwicklung der Abgasnachbehandlung mit innovativer Katalysatortechnologie kommt dabei eine entscheidende Bedeutung zu, wie dieser Beitrag der Audi AG zeigt.

Session OBD – OBD für Pkw und Nfz

All current OBD legislation worldwide are based on either the European or the US legislation. Emission limits for combustion engines are the basis for the OBD regulations. New technologies, e.g. the electrification, place other components as air conditioning system, brake system, electric motor and HV-battery in the USA directly or indirectly into the OBD focus. The influence of the network topology raised because the number of the electric control units cross-linked under OBD criteria increased, especially as only a limited number of legally allowed diagnostics addresses are available.

A discussion of errors in the measurement of gas temperatures

Over the last few years, major progress has been made in the field of cleaning exhaust gases. As a result of the increasingly tighter limits on exhaust gases, emissions have to be lowered even further in the future. Great importance is now being placed on the further development of after treatment of exhaust gases using innovative catalytic conversion technology, as shown in this article by Audi.
