Denoxtronic ­exhaust-gas ­treatment system

Denoxtronic introduces the reducing agent AdBlue into the exhaust gas flow. Media Center Download more information on this subject. The urea is then converted via thermolysis and hydrolysis into ammonia. Please try again later.

To comply with the new emission legislation all vehicle classes require active exhaust-gas treatment. The core task of the dosing module is the demand-based injection of diesel exhaust fluid into the exhaust manifold. Bosch is committed to long-term research and development, and can offer innovative solutions that make a significant contribution to meeting current legislative norms such as EU6d and EU6ff.

Without these cookies the website will not work properly. It reduces nitrogen oxides in exhaust gas and has been used in heavy commercial vehicles in Europe since To protect the dosing module in cold condition, the pressure line is purged, when engine is turned off by ignition key. Structure of the diesel exhaust fluid dosing module air-cooled. The supply module is welded on the tank bottom. System components System overview.

Many thanks for taking an interest in Bosch Mobility Solutions! Nitrogen oxides NO x are reduced in presence of oxygen. Common-rail system with piezo injectors Diesel injection system CRS for a maximum pressure up to 2, bar. D Active water cooling. The air-cooled variant of the dosing module is intended for installation underfloor.


Denoxtronic dosing control unit For efficient exhaust-gas treatment. The DEF is filtered by a lifetime filter. The concept has no backflow DEF line into the tank. A Diesel exhaust fuel intake.

The modular SCR system from Bosch is used to meter the diesel exhaust fluid reducing agent. By using SCR dosing system from Bosch, the denoxtronkc 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.

The supply module delivers the diesel exhaust fluid with required pressure into the dosing module. Press releases and pictures Visit bosch denoxtroniic portal. We will process your request promptly.

You can change this setting at any time by clicking on “change settings”. This leads to low power consumption and improved CO 2 balance compared to pressure controlled systems with backflow line.

The newest generation fulfills the strictest emission standards EU6 and US Contribution to achieve current and future emission targets The multiple spray variant of the dosing module support optimized performance for a wide variety of exhaust layouts. Latest Bosch Mobility videos on Youtube Watch now. 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.

Exhaust-gas treatment by selective catalytic reduction of nitrogen oxides SCR: Our remanufactured Bosch Denoxtronic modulessince we use only Bosch original spare parts, have the same quality as new parts. I have taken note of the privacy statement. Glow system for diesel engines From cold-start aid to adaptive glow system.


Denoxtronic 2.2: Exhaust-gas treatment to cut NOx-emissions

Latest Bosch Mobility videos on Youtube Watch now. Trade fairs and events Exchange ideas with our experts on site. The dosing module ensures a precise diesel exhaust fluid bisch control and handles its atomization and distribution in the exhaust pipe. Waiting for the Bosch put on the market the test software for the diagnostics, at the end ofour regeneration program regarding Bosch Denoxtronic modules became active.

Contribution to achieve current and future emission targets. We will process your request promptly. E Pressure sensor optional.

Electronically controlled atomization of diesel exhaust fluid in the exhaust train. Media Center Download more information on this subject. NO x sensor Outstanding regulation and diagnosis of catalytic nitrogen oxide reduction.

This pump operated only on demand, when DEF should be injected into the exhaust aftertreatment system.

Denoxtronic exhaust-gas treatment system

Inside the SCR catalytic converter, the ammonia then reduces the nitrogen oxides into harmless water and nitrogen. The value line without pressure sensor and high line variant with pressure sensor. Change settings Yes, I agree.

Operating principle of exhaust-gas treatment. High variance of hydraulic connector possibilities to install the watercooled dosing module in dnoxtronic installation spaces The DEF inlet can be manufactured out of plastic or stainless steel, to cope with high side load forces.
