Product Description
The working principle of the post-oxygen sensor is based on the influence of oxygen concentration on the sensor voltage. When the engine is running, the post-oxygen sensor will monitor the oxygen content in the exhaust gas and convert this information into a voltage signal. According to the change of oxygen content in the exhaust gas, the post-oxygen sensor will generate different voltage signals, reflecting the oxygen concentration in the exhaust gas.
The computer system of the vehicle will adjust the fuel mixture ratio and ignition timing of the engine according to the oxygen content information provided by the rear oxygen sensor to ensure the best combustion efficiency and reduce the emission of harmful gases. If the rear oxygen sensor detects that the oxygen content in the exhaust gas is abnormally high or low, the computer system of the vehicle will give an alarm and record the fault code for timely maintenance and adjustment.
Generally speaking, the function of automobile post-oxygen sensor is to monitor and control the oxygen content in vehicle exhaust emissions, help vehicles keep emissions in line with environmental standards, and also help to improve combustion efficiency and reduce fuel consumption. The normal operation of the post-oxygen sensor plays an important role in vehicle performance and environmental protection emissions.
