Lambda-Sensor with Y2O3-Stabilized ZrO2-Ceramic for Application in Automotive Emission Control Systems 770401
A description of a closed loop fuel metering system was given in the SAE-Paper “Closed Loop Exhaust Emission Control System with Electronic Fuel Injection” (3). The component of paramount importance in the control system is the Lambda-Sensor, about which has been reported in the SAE-Paper “Ceramic Aspects of the Bosch Lambda-Sensor” (5).
The paper reports on the work recently done for optimizing the Lambda-Sensor. As a result of this work the sensor of the latest design is an Y2O3-stabilized ZrO2-sensor whose temperature response is 150 °C lower and whose time of response in the CVS-test is the half. Generally, experimental work has been concentrated on improvement of
thermal, mechanical stability and resistivity against exhaust
