The oxygen sensor works similarly to a battery, with the element zirconia in the sensor acting like an electrolyte. The basic automobile oxygen sensor is the key feedback sensor in the EFI engine control system, and is the key part to control automobile exhaust emissions, reduce automobile environmental pollution and improve the fuel combustion quality of automobile engine. The oxygen sensor is installed on the engine exhaust pipe.
When installing automotive oxygen sensors, the following points need to be noted:
1. When installing the wiring harness, the Angle must not exceed 60°, and the bending rate of the wiring harness must be greater than R20 (radius ≥20mm) to avoid deformation or damage to the wiring harness.
2. The oxygen sensor should not be installed at the turn of the exhaust pipe to avoid affecting its normal operation.
3. The oxygen sensor should be installed away from the engine and exhaust pipe, as close to the turbocharger as possible, and downstream of the exhaust brake valve if one exists.
4. It is best to have a heat insulation device such as a heat shield between the oxygen sensor and the engine to prevent overheating from damaging the sensor.
