Oxygen Sensor A6365420218 For Mercedes W636

Automobile oxygen sensor is a complex device composed of multiple components, mainly including the following parts:

1. Oxygen ion conductor: the core component of oxygen sensor, usually using zirconia or yttria stabilized oxygen ion electrolyte. The oxygen ion conductor is responsible for measuring the oxygen content in the exhaust gas and generating the corresponding voltage signal.

2. Reference gas chamber: used to compare the oxygen content of exhaust gas and ambient air to ensure the accuracy and stability of the sensor.

3. Shell: it is used to protect the internal components of the sensor, and also plays the role of fixing and supporting the sensor.

4. Wiring terminal: used to connect the sensor with the electrical system of the vehicle and transmit the voltage signal generated by the sensor to the engine control unit (ECU).

5. Thermocouple: Some automobile oxygen sensors also include thermocouples to keep the working temperature of the sensor to ensure the accuracy and stability of the sensor.

Generally speaking, the main components of automobile oxygen sensor include oxygen ion conductor, reference gas chamber, shell, terminal and possible thermocouple. These components work together, so that the oxygen sensor can accurately measure the oxygen content in the exhaust gas and generate the corresponding voltage signal, which helps the engine control system to adjust the fuel mixture ratio in real time to ensure the combustion efficiency and exhaust emission of the engine meet the requirements. Each component of automobile oxygen sensor plays an important role in the whole system and is the key component to ensure the normal operation of the engine and environmental protection emission.
