A distinction is made between two variants.

The core task of the dosing module is the demand-based injection of denoxtromic exhaust fluid into the exhaust manifold. Denoxtronic dosing control unit For efficient exhaust-gas treatment. 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.

E Pressure sensor optional. The Denoxtronic metering system injects diesel exhaust fluid DEFan aqueous urea solution of Trade fairs and events Exchange ideas with our experts on site.

Inside the SCR catalytic converter, the ammonia then reduces the nitrogen oxides into harmless water and nitrogen. High variance of hydraulic connector possibilities to install the watercooled dosing module in narrow installation spaces The DEF inlet can be manufactured out of plastic or stainless steel, to cope with high side load forces.

To comply with the new emission legislation all ddenoxtronic classes require active exhaust-gas treatment. Media Center Download more information on this subject. This leads to low power consumption and improved CO 2 balance compared to pressure controlled systems with backflow line. Ddenoxtronic lambda sensor For use in gasoline and diesel engines. The system consists of supply and dosing modules in addition to the optional DCU.


The water-cooled dosing module is actively flushed with coolant. To protect the dosing module in cold condition, the pressure line is purged, when engine is turned dwnoxtronic by ignition key. Overview all system components. Please try again later. Operating principle of exhaust-gas treatment. The concept has no backflow DEF line into the tank.

The value line without pressure sensor and high line variant with pressure sensor. Denoxtronic dosing module For efficient exhaust-gas treatment. Common-rail system with solenoid injectors Diesel injection system CRS for a maximum pressure up to 2, bar. The second generation for commercial vehicles: Electronically controlled atomization of diesel exhaust fluid in the exhaust train.

All products Operation System benefits Contact Other systems. Low power consumption in driving cycle, due to activation only on demand — contribution to lower CO 2 emission of the vehicle.

In automotive applications, this reducing agent is obtained from the carrier substance urea, NH 2 2 CO. Differential pressure sensor Different application possibilities in the vehicle. Denoxtronic introduces the reducing agent AdBlue into the exhaust gas flow. Privacy settings allow you to enable or disable cookies.

This website uses cookies for functional, comfort and statistics purposes. 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.

Indue to the future legislation about restriction of vehicle emissions and the rapid increase of the Bosch Denoxtronic moduleswe made the decision to extend our remanufactured products to them. Due to the flat design of the filter, the residual volume in dejoxtronic tank is below ml — a big benefit for the vehicle manufacturer for tank design and usable tank volume. Comfort cookies These cookies offer additional functionality or make the website easier to use. Structure of the diesel exhaust fluid dosing module water-cooled.

We will process your request promptly. It sprays the required diesel exhaust fluid DEF into the exhaust system. Bosch understands the requirement for a coordinated system design that boosch account of all interrelations and satisfies this demand with holistic solutions.

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. D Active water cooling. The air-cooled variant of the dosing module is intended for installation underfloor. Latest Bosch Mobility videos on Youtube Watch now.
