System Requirements Length [mm]: 810 Number of circuits: 3 Product Description Niterra is a leading manufacturer of oxygen sensors for original equipment and the aftermarket. Car and motorbike manufacturers, dealers and workshops have been relying on the sensor specialist's expertise for decades. Oxygen sensors are one of the most important technologies for reducing pollutant emissions. The oxygen sensor determines the residual oxygen content in the exhaust gas and provides the vehicle's engine control unit (ECU) with precise information about the current mixing ratio of air and fuel, the so-called oxygen value (λ). Based on this information, the control unit can optimise the fuel-air ratio. The oxygen sensor therefore not only contributes to the effective reduction of pollutant emissions, but also optimises fuel consumption and ensures a long service life for the catalytic converter. As the oxygen sensor is subject to a certain amount of ageing, it should be checked at regular intervals to ensure that it is working properly and replaced if necessary. Any malfunctions are noticeable through higher fuel consumption, lower engine performance and increased exhaust emissions. If a vehicle fails the exhaust emissions test (AU), replacing the oxygen sensor could reduce the exhaust emission values to the prescribed values.
