What is the Nernst formula ?
A:“R”in the formula is the ideal gas constant;“T" is the absolute temperature of the sensing element; “F” is faraday constant; “p7O2)”is the oxygen partial pressure of the exhaust side;“p(O2)" is the oxygen partial pressure in air. Thus, at a certain temperature, if the reference gas is the air (ie., the reference oxygen partial pressure is known), the E value can be determined by the oxygen content of exhaust. A high voltage(0.6 ~ 1V) is generated between the electrodes when the oxygen concentration is low on the exhaust side of the substrate, and the voltage signal is sent to the ECU and amplified. The ECU processes high voltage signal as a rich mixture, and low voltage signal (about 0.1V) is considered as a dilute mixture. Based on the voltage signal feedback of the oxygen sensor, the computer will dilute or enrich mixture accordingly to reach optimal theoretical air fuel ratio.
What’s the operating principle of the Oxygen sensor?
A: The principle for concentration cell type oxygen sensor is that the difference of the Exhaust, oxygen partial pressure of the two ZrO₂ solid electrolytes provides concentration.potential. It uses the characteristics of ZrO₂ with oxygen ion conduction and no electron conduction at high temperature. Nernst formula can be used to obtain the concentration potential value.
What’s the Oxygen sensor ?
A:Oxygen sensor is the major sensor component in electronic fuel injection engine control system, and is the key part to control automobile exhaust emission, reduce pollution to the environment and improve fuel combustion quality of automotive engine. Oxygen sensor is used in the feedback control system of the electronic control fuel injection device, to detect the concentration of oxygen in the exhaust gas and whether the air fuel ratio is lean or rich. lt is also used to monitor theoretical air fuel ratio (14.7:1) combustion in the engine, and provide feedback signals to the computer.
What is “Engine Warning Lights”?
A: Perhaps the most obvious one yet, but definitely the one most people usually ignore. Although the sensor itself isn’t mounted inside the engine bay, any failure of the NOx sensor will trigger an engine warning light. It’s not a bulletproof method of finding NOx sensor faults and issues, but it does paint a much clearer picture of what your car’s experiencing. Scanning for error codes after a check engine light usually reveals whether you’re dealing with a broken NOx sensor right away.
What is “Unstable idle” ?
A: Since the ECU has no way of knowing what’s going on with the engine, it has to assume a worst-case scenario. Fuel injectors designed to maintain a constant flow of fuel to the engine will sporadically starve and/or surge, neither of which is good for your car in the long run.
What is “Higher Fuel Consumption” ?
A: If the sensor isn’t working properly the ECU isn’t getting any feedback about the status of the exhaust gasses, so there’s no way for the computer to know or work out the necessary fuel mixture or air-to-fuel ratio. This forces the ECU to assume a worst-case scenario and run a rich fuel mixture to ensure maximum power in poor conditions.
Symptoms of a bad NOX Sensor ?
A: >Higher Fuel Consumption.
> Paʻa ʻole.
> Uku Uku Enekinia
What is NOx Sensor for NOx aftertreatment system ?
A: The NOx sensor is part of the NOx reduction aftertreatment system used in diesel vehicles with urea based SCR systems. The sensor located upstream of the SCR catalyst directly measures the engine-out NOx gas concentration, which helps determine the optimum amount of urea injection.
The NOx sensor downstream of the SCR catalyst is used to monitor the performance of the catalyst. Accurate NOx measurement is in high demand to comply with increasingly strict NOx emissions regulations. The NOx sensor is also capable of measuring O2 concentration, just like a wide range air-fuel sensor.
