Where is the car oxygen sensor installed?

The oxygen sensor of a car is generally installed on the exhaust pipe of the engine, which is mainly related to its working nature. After all, the oxygen sensor belongs to the feedback sensor in the control system of the EFI engine. The sensor is mainly used for Control the emission of automobile exhaust to reduce the pollution to the external environment, so as to better improve the quality of engine fuel combustion. Moreover, the oxygen sensor installed on the general car is basically composed of two.

It's just that they are not together, most of the first oxygen sensor will basically be installed in threeYuanIn front of the catalytic converter, as for the second one, it will be installed after the three-way catalytic converter. Therefore, it also confirms what is said in the first paragraph that the sensor is not only used for feedback, but also can better improve the combustion efficiency of the engine, thereby reducing the pollution of automobile exhaust emissions.

Therefore, the owner of the oxygen sensor in the car can distinguish it in this way. It can be roughly bounded by the three-way catalytic converter. The front oxygen sensor before the three-way catalytic converter is called the front oxygen sensor. Its main job is to detect the combustion of the engine. The oxygen sensor behind the three-way catalytic converter can be called the rear oxygen sensor, and its main function is to detect the oxygen sensor behind the three-way catalytic converter.

However, in the process of use, the car owner should also check the oxygen sensor every once in a while. After all, sometimes the oxygen sensor is prone to failure after work. The most common failures are poisoning failures, ceramic fragmentation and Line disconnection etc. These failures will affect the normal use of the oxygen sensor, so the specific conditions of the two oxygen sensors should be checked at regular intervals.
