Bosch's fifth-generation SCR system's urea pump is key to overall system performance and is widely used in vehicles meeting the China VI emission standard, boasting significant technical advantages. Widely used in passenger cars and light trucks, Bosch's fifth-generation SCR system, a key component of Bosch's diesel aftertreatment system, inherits and develops the advantages of previous generations. The system's main components include the DCU (urea injection control unit), urea tank, urea supply unit (including a high-efficiency urea pump), urea metering injection unit, hydraulic lines, electrical wiring harness, and sensors.

The DeNOx 5.x system achieves efficient nitrogen oxide conversion and stable system operation by optimizing hydraulic and electronic control components. The Bosch DeNOx 5.x after-treatment system, as an important part of Bosch's diesel after-treatment system, has a schematic diagram that shows the interrelationships and working principles of the system's components. The system precisely controls the urea injection rate through the DCU and, in conjunction with an efficient urea pump, optimizes the SCR reaction. The synergy of core components such as hydraulic piping, electrical wiring, and sensors ensures the stability and reliability of the after-treatment system.

The DeNOx 3.1 system focuses on the powerful drive of the urea pump, integrating the synergistic effects of various components to achieve efficient aftertreatment. The Bosch DeNOx 3.1 aftertreatment system, another masterpiece of Bosch diesel aftertreatment technology, features a schematic diagram that deeply analyzes the linkage and operating logic of the system's various components. This system also relies on the precise control of the DCU, which powerfully drives the urea pump to promote efficient SCR reactions. Furthermore, the precise coordination of core components such as the hydraulic piping, electrical wiring harness, and sensors forms the solid foundation of the aftertreatment system.
