exhaust gas sensor.

other concepts in the future, the installation space for exhaust gas sensors will be increasingly narrower. In addition, the sensors are exposed to increasingly higher temperatures. Have to be smaller, versatile and, above all, faster: These will be the salient features of future developments. For compliance of emissions that will harden permanently will require high quality materials that allow higher temperatures, even at hotspots. Application

Engine Management Function

• Measuring the concentration of oxygen in the exhaust gases. This magnitude of measurement is the basis for the three-way catalyst (gasoline engine) and Lambda control function (diesel).
