Denoxtronic exhaust-gas treatment system
Trade fairs and events Exchange ideas with our experts on site. Electronically controlled delivery of diesel exhaust fluid into the denoxtroniv train. Press releases and pictures Visit Bosch press portal. Due to the flat design of the filter, the xenoxtronic volume in the tank is below ml — a big benefit for the vehicle manufacturer for tank design and usable tank volume. The supply module delivers the diesel exhaust fluid with required pressure into the dosing module. 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.
Contribution to achieve current and future emission targets. The value line without pressure sensor and high line variant with pressure sensor. Denoxtronic dosing control unit For efficient exhaust-gas treatment. Bosch understands the requirement for a coordinated system design that takes account of all interrelations and satisfies this demand with holistic solutions.
In order to restrict vehicle emissions, the emission limits are continuously being reduced worldwide. Without these cookies the website will not work properly. This pump operated only on demand, when DEF should be injected into the exhaust aftertreatment system. 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.
Change settings Yes, I agree. Inside the SCR catalytic converter, the ammonia then reduces the nitrogen oxides into harmless water and nitrogen. A Diesel exhaust fluid inlet. The main function of the supply module is to deliver the DEF form the tank to the dosing module via a precise solenoid membrane pump.
The Denoxtronic metering system injects diesel exhaust fluid DEFan aqueous urea solution of The supply module is part of the Bosch Denoxtronic system responsible for delivering diesel exhaust fluid DEF that reduces nitrogen oxide into the exhaust system.
C Cooling adapter for passive air cooling. Common-rail system with solenoid injectors Diesel injection system CRS for a maximum pressure up to 2, bar. The newest generation fulfills the strictest emission standards EU6 and US In the catalytic converter, the ammonia reduces the nitrogen oxide to water and nitrogen.

Media Center Download more information on this subject. The Denoxtronic has been developed for passenger-car and light-duty-vehicle applications. Many thanks for taking an interest in Bosch Mobility Solutions! I have taken note of the privacy statement. AdBlue is administered in the required quantity – precisely adjusted to the current operating status.
Denoxtronic introduces the reducing agent AdBlue into the exhaust gas flow.
A distinction is made between two variants. The urea is then converted via thermolysis and hydrolysis into ammonia. Please activate denoxtronnic and refresh your browser. Differential pressure sensor Different application possibilities in the vehicle. This leads to low power consumption and improved CO 2 balance compared to pressure controlled systems with backflow line. The core task of the dosing module is the demand-based injection of diesel exhaust fluid into the exhaust train.
Denoxtronic exhaust-gas treatment system
Denoxtronic dosing control unit For efficient exhaust-gas treatment. There are denpxtronic variants in the portfolio: Sprays with different spray angles and flow rates allow the perfect distribution of ammonia in the SCR catalytic converter.
The dosing module ensures a precise diesel exhaust fluid quantity control and handles its atomization and distribution in the exhaust pipe.
