Nox Sensors

NOx sensors, also known as nitrogen oxides sensors, are devices that are installed on heavy goods vehicles (HGVs) to measure the levels of nitrogen oxides (NOx) in the exhaust gases. NOx is a group of highly reactive gases that are produced during the combustion of diesel fuel and can contribute to air pollution and negative health effects. NOx sensors work by measuring the amount of NOx in the exhaust gases and sending that information to the engine control module (ECM). The ECM then uses that information to adjust the air-fuel mixture and the timing of the fuel injection to reduce the amount of NOx that is produced. NOx sensors are an important component of the emissions control systems of HGVs, as they help to ensure that the vehicle is emitting low levels of pollutants. They are typically located in the exhaust system, close to the engine. It's worth mentioning that NOx emissions have been heavily regulated in recent years and have become a major focus in the efforts to reduce air pollution. NOx sensors are therefore becoming increasingly important in order to meet the emissions standards of different regions and countries.
