Abstract

Oxygen sensors taken from the aftertreatment systems of 4 vehicles which had been aged in domestic filed were examined for aging pattern using a idle engine bench. The sensors were then cut into each layers along their components and characterized for poisoning, surface area and morphology. This study shows that amplitude and mean value of aged sensors are seriously affected by high temperature and oil components of exhaust gas.
