Motorists are no longer surprised that vehicles are constantly being modernized. Many interesting technical solutions that are found today in almost all passenger vehicles were developed back in the nineties - that time was rich in innovations in the automotive industry. However, there are many such solutions that many motorists might not know about. One of them is the MEAT & DORIA brand NOx Sensor, NOx Catalyst, otherwise called the nitrogen oxides sensor or the lean mixture sensor. Today, more and more cars are equipped with such devices, which is explained by the increased requirements for environmental friendliness.

The operation of NOx sensor

The current requirements for the environmental performance of internal combustion engines are strict. Most of the cars with gasoline engines have so-called. direct injection, and the engine itself at partial load consumes a lean mixture. Let us explain: the minimum required amount of oxygen, in fact, atmospheric air, is used to prepare a lean mixture. Even when burning a lean mixture, a large amount of oxides with a carbon and nitrogen base is formed. Conventional catalysts capture the former, while the latter can become a problem - it is much more difficult to neutralize nitrogen oxides. Additional storage catalysts for nitrogen oxides help to solve the problem partially. Such catalysts have a certain storage capacity, which must be recorded. This task the NOx sensor takes on.
