Oxygen sensor failure performance


The fundamental effect of the oxygen sensor is to detect the oxygen concentration in the tail gas, and then the ECU (engine system control computer) will determine the combustion status of the engine (front oxygen) or the working efficiency of the catalyst (postponomy (postponed) provided by the oxygen sensor (post -oxygen)oxygen).Aerobic ingredients and titanium oxide.


Failure method:


If the oxygen sensor fails, the engine performance is poor, the λ adjustment is fixed, the idle speed is unstable, the emission value is abnormal, the fuel consumption is increased, and the spark plugs are charcoal.Oxygen sensor poisoning is a frequent and difficult to prevent and control, especially cars with lead -containing gasoline.

The above is the introduction and description of 12V Xin Xin Nox Sensor 5WK9 6680A For Fuso, I hope it can be helpful to you.
