In the automotive control system, there is a very important component, which is the oxygen sensor. What is the function of an oxygen sensor and what is it? Today we are going to popularize science.

The oxygen sensor is actually a key feedback sensor in the electronic fuel injection engine control system, mainly divided into two types, namely zirconia and titanium dioxide, both of which are installed on the exhaust pipe of the engine.

The function of oxygen sensors is to control the exhaust emissions of automobiles and effectively reduce their air pollution to the environment. In addition, it can also improve the fuel combustion quality of car engines, helping to reduce fuel consumption. If there is a problem with the oxygen sensor, the computer of the electronic fuel injection system cannot obtain accurate information on the oxygen concentration in the exhaust pipe, and cannot provide feedback to control the air-fuel ratio, resulting in an increase in engine fuel consumption, exhaust emissions, and even engine idle instability, misfire, wheezing and other faults. Therefore, timely repair or replacement of oxygen sensors is very important.
