How does a broken front oxygen sensor affect the car
The broken car front oxygen sensor will not only make the vehicle exhaust emissions exceed the standard, but also worsen the engine working condition, leading to the vehicle idling stall, engine misalignment, power reduction and other symptoms, because the oxygen sensor as an important part of the electronic control fuel injection system
Function of oxygen sensor: The fundamental function of oxygen sensor is to detect the oxygen concentration in the tail gas. Then the ECU (engine system control computer) will determine the combustion condition of the engine (pre-oxygen) or the working efficiency of the catalytic converter (post-oxygen) through the oxygen concentration signal provided by the oxygen sensor. There's zirconia and titanium oxide.
Oxygen sensor poisoning is a frequent and difficult failure to prevent, especially in cars that regularly run on leaded gasoline. Even new oxygen sensors can only work for a few thousand kilometers. If it is a mild case of lead poisoning, then a tank of lead-free gasoline will remove the lead from the surface of the oxygen sensor and restore it to normal operation. But often due to too high exhaust temperature, and make lead intrude into its interior, hinder the diffusion of oxygen ions, make oxygen sensor failure, then can only be replaced.
In addition, oxygen sensor silicon poisoning is a common occurrence. Generally speaking, the silica generated after the combustion of silicon compounds contained in gasoline and lubricating oil, and the silicone gas emitted by the improper use of silicone rubber seal gaskets will make the oxygen sensor fail, so the use of good quality fuel oil and lubricating oil.
