B5.1 - Recent Developments in Automotive Exhaust Gas Sensing

Ralf Moos
Increasing fuel costs combined with the pressure on the automotive industry to reduce CO2 emissions lead to booming market shares for Diesel passenger cars. They are operated leanly. Therefore, nitrogen oxide (NOx) removal with conventional three way catalysts (TWC) is not possible. At the same time, NOx emission limits have been strongly reduced. Leanly operated gasoline direct injection engines are another way for reducing fuel consumption. Both lean concepts require novel exhaust gas aftertreatment concepts,...
