Definition and function of oxygen sensor
Definition:
An oxygen sensor is a measuring element that utilizes ceramic sensitive elements to measure the oxygen potential in heating furnaces or exhaust pipes. Based on the principle of chemical equilibrium, it calculates the corresponding oxygen concentration, enabling the monitoring and control of the air-fuel ratio during combustion within the furnace.
Function:
It determines whether there is excess oxygen in the exhaust after engine combustion. It converts the oxygen content into a voltage signal and transmits it to the Engine Control Unit (ECU), enabling the engine to achieve closed-loop control with the target of excess air factor.
It ensures that the three-way catalytic converter achieves maximum conversion efficiency for the three pollutants in the exhaust: hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx), thereby maximizing the conversion and purification of emissions pollutants.
lifespan of oxygen sensor :
100，000 kilometers is a small hurdle for a vehicle. A car that is not well maintained will enter frequent failures outbreak period. The oxygen sensor is a part that almost no one has thought of replacing., but it is the one that must be paid attention to and replaced Irregular. The main materials of the oxygen sensor are platinum and zirconium oxide. Its service life is generally 8-10 kilometers. There are three types of oxygen sensor failure modes: CO poisoning, sulfur and phosphorus poisoning, lead poisoning, silicon poisoning, and manganese poisoning. The quality of gasoline and lubricating oil has a great impact on the life of the oxygen sensor.
