At the very begin of automobilem, people just care about the basic function of automobile, while with the development of automobile, people begin to care about the safety, be aware of the harm of automobile exhaust to the environment. So people begin to contro the polution of exhaust.

Since Bosch Company in Germany and Toyota Company in Japan took the lead in applying oxygen sensors to automobiles in 1976, and serialized their products, in just over ten years, automobile #oxygensensors have been widely used in controlling air-fuel ratio and purifying exhaust gas in Japan, the United States and Europe, with a total of hundreds of millions of vehicles.

The main function of the automobile oxygen sensor is to monitor the oxygen content in the exhaust gas of the engine, and output signal voltage according to the measured data, which is fed back to the ECU, so as to control the amount of fuel injection, and make the automobile engine in the best combustion state at any time. Combined with three-way catalyst, the harmful components in the exhaust gas of the automobile can be reduced by more than 80%, and the oil can be saved by 5%~20%. This is a necessary means to save energy and reduce pollution, which has attracted the attention of all countries in the world.
