Exhaust gas oxygen sensor for Land Rover Center oxygen sensor LR142730 Lambda sensor
Exhaust gas oxygen sensor for Land Rover Center oxygen sensor LR142730 Lambda sensor
Oxygen sensor
OE Numbers: LR142730 LR116639
Vehicle Compatibility: Land Rover
The oxygen sensor is a critical component within the exhaust system, primarily functioning to monitor the oxygen concentration in exhaust gases in real time and convert this into an electrical signal. This enables the ECU to dynamically adjust fuel injection, maintaining the air-fuel ratio at an optimal value (14.7:1 for petrol vehicles), while simultaneously monitoring the efficiency of the three-way catalytic converter.
- Closed-loop control: The output signal drives the ECU to correct fuel injection, reducing fuel consumption and CO, HC, NOₓ emissions while enhancing three-way catalytic converter efficiency (achieving over 90%).
- Operating condition adaptation: Wide-band sensors support complex conditions such as lean-burn combustion and direct injection, precisely covering the excess air ratio range λ=0.7-4.0.
- Catalytic Monitoring: The rear oxygen sensor (post-catalytic converter) compares signals with the front sensor to assess catalytic purification efficacy, triggering fault codes upon anomalies.
- Rapid Activation: The heated design rapidly reaches operating temperatures exceeding 300°C, reducing cold-start closed-loop control delays.
