What is the function of NOx sensor?
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.
What does NoX sensor stand for in car?
What is a NOx Sensor? We shall begin by going over what a NOx sensor is and how it can affect your vehicle. NOx stands for nitrogen oxide, and the sensor measures the levels which your vehicle puts out into the world. Typically, you will find these indicators in vans, but they can be put into cars as well depending upon the situation.
How does a nitrogen oxide NOx sensor work?
Most NOx sensors function by initially removing oxygen before breaking down the nitrogen oxides to create a reading. If the reading is too high (or is lower than usual), the SCR system will respond by releasing more (or less) urea based on the information provided by the sensor. Why does the NOx sensor fail?
Which is the most recent area of NoX sensor application?
The most recent area of NOx sensor application are SCR systems for light and heavy duty diesel engines. To satisfy various OBD requirements, SCR systems typically use a NOx sensor downstream of the SCR catalyst.
What happens if the content of NOx still is 0 ppm?
If the content of NOx still is 0 ppm or/and becomes 0 ppm, the NOx sensor is damaged (the sensor element has aged) and it (the sensor) has to be replaced.
How does a knock sensor work?
The knock sensor works by sensing the “knocks” or noises the engine makes when the pressure and heat in the engine is too much. When this happens, the sensor picks up the noise or the vibration being made.
What does the knock sensor do?
Here is the answer for what does the knock sensor do: Diminished Power Once your car detects the bad knock sensor, you will see your vehicle losing its power. Vanished Fuel Mileage It may even slow down the acceleration of the vehicle, especially on the highway. Engine Acts Unusually
What does a knock sensor control?
The knock sensor in an engine is used to send signals to the engine-control computer if this action is detected, preventing a detonation from happening. In a sense, the knock sensor is a microphone placed in the engine to listen to any unusual noises that the engine makes. Continue reading below Our Video of the Day
Where is the knock sensor located?
Knock Sensor. The knock sensor is located on the engine block, cylinder head or intake manifold. This is because its function is to sense vibrations caused by engine knock or detonation.
