The NOx sensor is an important part of the exhaust aftertreatment system for reducing the concentration of harmful NOx substances (nitrogen oxides). It is used in diesel vehicles with an SCR (Selective Catalytic Reduction) system based on urea (AdBlue). The sensor enables compliance with stringent Euro 5 and 6 emissions standards, ensures optimal dosing of AdBlue in the engine exhaust system, and thus effectively reduces environmentally harmful nitrogen oxides. Construction, principle of operation, faults The NOx sensor consists of a probe and a controller that are permanently connected to each other by means of a wiring harness. The sensor is mounted in the exhaust system and is used to detect nitrogen oxides in the exhaust gases. It should be remembered that this liquid freezes at -11 o C. 5%. g.

We all know how important access to technical data is for a mechanic. It is no different in the case of a workshop servicing air conditioning in vehicles. Information about the size of the A/C system in the serviced car is crucial for its efficient operation. Slightly larger (up to 10%) application of too much refrigerant causes not only a drastic decrease in the cooling efficiency of the interior, but above all, it will have a catastrophic effect on the condition of the air conditioning compressor. Such action will result in a costly failure in a short time. Understanding these threats and market needs, we encourage you to use the following technical material and link.
