Nox Sensor
A nox sensor is a type of automotive sensor that detects and measures the levels of nitrogen oxide (NOx) in the exhaust system of a vehicle. It is an important component of modern vehicles' emission control systems, as NOx emissions can contribute to air pollution and smog. The sensor works by analyzing the amount of oxygen and NOx in the exhaust gas, and sends signals to the engine's computer to adjust fuel injection and ignition timing accordingly. This helps to reduce NOx emissions and improve fuel efficiency. NOx sensors are typically found in diesel engines, but can also be used in gasoline engines with lean-burn technology.
