OXYGEN/LAMBDA SENSORS

PRECISE COMBUSTION

Flawless Pollution Control

To ensure the reduction of harmful emissions produced by the internal combustion engine, the lambda or oxygen sensor has become an important piece of technology. As one of the leading suppliers of oxygen sensors both for OEMs and the Aftermarket, Niterra is continually improving its oxygen sensors to make engines cleaner and more efficient.

Oxygen Sensor Technologies

With its NTK oxygen sensors launched in the 1980s, Niterra was among the pioneers in this field. Since then, the reduction of harmful emissions has made significant advances, not least thanks to the development of innovative technologies and extensive research.

Today, highly efficient ceramic heaters in lambda sensors ensure, for example, that the sensors start measuring sooner and respond faster. To achieve more accurate measurements in order to meet the ever more stringent Euro standards, huge efforts are being made in the continuous improvement of the ceramic components. In addition, a variety of sensor types have been developed catering to specific applications. They include broadband sensors and lambda sensors whose electric resistance changes depending on the air-fuel ratio.

NTK Lambda sensors for adjusting air-fuel ratio

Oxygen Sensor Requirements

Proper conversion of undesirable gases can only occur at a set air-fuel ratio. This is why an oxygen sensor has the task of precisely measuring the ratio present in exhaust gases. Moreover, the sensor informs the vehicle's ECU (Electronic Control Unit) in order to adjust the air-fuel ratio. This entire process helps firstly to effectively reduce harmful emissions. Secondly it optimises fuel consumption and ensures a long service life of the catalytic converter.
