The first generation for commercial vehicles, consisting of a supply module with integrated DCU, dosing module and atomizer. Denoxtronic dosing control unit. Back to the top. To comply with the new emission legislation all vehicle classes require active exhaust-gas treatment. E Pressure sensor optional. Many thanks for taking an interest in Bosch Mobility Solutions! In the catalytic converter, the ammonia reduces the nitrogen oxide to water and nitrogen.
Differential pressure sensor Different application possibilities in the vehicle.
Denoxtronic exhaust-gas treatment system
Particulate matter sensor Constant monitoring for a low-emission future. Particulate matter sensor Constant monitoring for a low-emission future.
By using SCR dosing system from Bosch, the diesel engine can be operated with lower fuel consumption and thereby lower CO 2 emission Low installation space needed, due to flat and standardized design of the supply module.
Trade fairs and events Exchange ideas with our experts on site. Low power consumption in driving cycle, due to activation only on demand — contribution to lower CO 2 emission of the vehicle. denixtronic
The value line without pressure sensor and high line variant with pressure sensor. The hydraulic connection on the dosing module and the coolant connections can be aligned in different directions to make them easier to mount in narrow installation spaces on the engine. Urea is highly soluble in water and can therefore be added to the exhaust gas in the fluid form of an easily metered urea-water. NO x sensor Outstanding regulation and diagnosis of catalytic nitrogen denoxtronix reduction.
The supply module delivers the diesel exhaust fluid with required pressure into the dosing module. Targeting cookies These cookies are used to customize information and advertising to your interests based on the content you have visited before.
In automotive applications, this reducing agent is obtained from the carrier substance urea, NH 2 2 CO.

Denoxtronic: Urea dosing system for SCR systems
boscb The dosing module ensures a precise diesel exhaust fluid quantity control and handles its atomization and distribution in the exhaust pipe. The DEF is filtered by a lifetime filter. Structure of the diesel exhaust fluid dosing module air-cooled. Imprint Legal Privacy Bosch. Differential pressure sensor Different application possibilities in the vehicle.
The Denoxtronic system supports the vehicle manufacturer to denoxtrlnic current and upcoming emission regulations. The main task of the control unit in the dosing control device is the model-based calculation of the required dosing quantity according to a predetermined dosing strategy.

Contribution to achieve current and future emission targets The multiple spray variant of the dosing module support optimized dnoxtronic for a wide variety of exhaust layouts. Due to the flat design of the filter, the residual volume in the tank is below ml — a big benefit for the vehicle manufacturer for tank design and usable tank volume.
The concept has no backflow DEF line into the tank. The urea is then converted via thermolysis and hydrolysis into ammonia.
D Active water cooling. C Cooling adapter for passive air cooling. We will process your request promptly. Exhaust-gas treatment by selective catalytic reduction of nitrogen oxides SCR: Bosch understands the requirement for a coordinated system design that takes account of all interrelations and satisfies this demand with holistic solutions. Privacy settings allow you to enable or disable cookies.
The main function of the supply module is to deliver the DEF from the tank to the dosing module via a precise solenoid membrane pump. Many thanks for taking an interest in Bosch Mobility Solutions! The air-cooled variant of the dosing module is intended for installation underfloor.
