How does a hydrocarbon doser work?

According to the company, the hydrocarbon dosing system controls the dosing of diesel fuel into the exhaust upstream of the diesel oxidation catalyst to allow efficient regeneration of the diesel particulate filter.

What is the Bosch Departronic system?

With Departronic, Bosch offers a diesel fuel metering system for the regeneration of particulate filters especially for heavy commercial vehicles. The system allows the particulate filter to be regenerated thanks to a targeted injection of diesel fuel into the exhaust gas.

What does a dosing module do?

The dosing module is a component in the Bosch system that helps to reduce nitrogen oxide emissions in the exhaust system. Its job is to spray the urea-water solution into the exhaust system.

What pressure does adblue run?

The doser software controls the urea flow rate by adjusting the pumping frequency. The injector nozzle opens at 20 bar and achieves a peak injection pressure of 50 bar.

What is a fuel doser valve?

During active regeneration, the doser valve injects a fine mist of fuel into the exhaust stream, where it then ignites on the surface of the DOC to raise the exhaust temperature and oxidize the particulate matter in the CDPF. The Doser assembly also includes a fuel pump and filter.

What is a seventh injector used for?

The “seventh injector” mainly appears on the engine after the DPF is used to process the fuel-assisted combustion regeneration technology.

What is Dosing Control Unit?

The selective catalytic reduction (SCR) dosing control unit monitors and controls the dosing and heating elements that are vital for the working of the SCR in order to curb NOx emission. The global SCR dosing control unit market can be segmented based on vehicle type, sales channel and region.

What year did diesel exhaust fluid start?

2010
With the goal of reducing engine emissions further, specifically regarding NOx and particulate matter, the EPA introduced diesel exhaust fluid (DEF) 2010.

Can you overfill AdBlue tank?

Do not overfill the AdBlue reservoir. On some cars, the AdBlue pump and circuitry are located on top of the tank, so overfilling risks moisture contamination that can damage the circuits.

Can you clean a doser valve?

You have two options when it comes to cleaning your doser valve. You can either can get it cleaned at a dealership or repair facility, or you can do it yourself. Cleaning the doser valve yourself can be relatively straightforward and cost-effective. You just need some basic hand tools and brass bristled brush.
