2.1.4 Automotive Exhaust Gas Sensing – Current Trends

Kathy Sahner
Robust chemical sensors are required to efficiently control automotive combustion engines. For both gasoline and diesel applications, various types of the ceramic lambda probe for oxygen monitoring are well established. In the event of tighter limits of emission legislation and on-board diagnostics, interest in monitoring additional exhaust gas species grows continuously. This development leads to new generations of exhaust gas sensors, in particular for Diesel applications.
