Replacing QLS sensor in SCR system

The system uses a chemical reducer called DEF, also known as Diesel Exhaust fluid, to reduce harmful nitrogen oxides and make them harmless. The SCR system not only reduces nitrogen oxides but also has a control system that monitors engine temperature and pressure to maintain peak performance.

The Aftertreatment Control Module, or ACM, is responsible for ensuring that the SCR system works efficiently. It controls the NOx levels in the system and determines if the DPF should be cleaned. In some embodiments, an input function is provided by the ACM module to determine if please click the up coming website page DPF must clean to meet emission thresholds. Other embodiments of the ACM module include fewer features and functionality.
