- In the face of tightening GHG regulations, vehicle ICE powertrains must now adopt new methods to achieve superior fuel economy and further reduce tailpipe gaseous emissions. Some recent strategies by OEMs for meeting these objectives include the downsizing of their engine displacement, the adoption of aggressive turbocharging, and the close-coupled locating of the exhaust aftertreatment. Ceramic substrates, the principal enabling technology within established aftertreatment systems, must further demonstrate enhanced performance qualities to survive and continue to perform in this more severe operating environment. This paper will summarize performance studies conducted on advanced ceramic substrates of high porosity and thin wall monolith cordierite design. The testing results correspond with OEM technical expectations and include the following: thermal shock resistance studies from engine exhaust heat up events, mechanical strength evaluation from harsh vibration exposure, and material durability observations throughout FUL aging process.
