PRODUCTS FUNCTION:

The Denoxtronic dosing system injects AdBlue®, a solution of 32.5% urea in water, into the exhaust-gas flow. The urea is then converted via thermolysis and hydrolysis into ammonia,which in turn breaks down the nitrogen oxides in the exhaust into water and nitrogen.

A supply component extracts AdBlue® from a storage tank via a diaphragm pump, which then pressurizes it to the necessary range of 4.5 to 8.5 bar for effective atomization. The dosing component determines the ideal amount of AdBlue® needed, utilizing engine performance and sensor information to enhance NOx reduction efficiency. After calculating the required amount, the dosing component injects the finely dispersed urea solution into the exhaust stream prior to the SCR catalyst. An engine or dosing control unit manages the dosing and heating processes, as well as oversees onboard diagnostics. Optimal nitrogen oxide reduction is attained through accurate operational data and adjustments to meet the specific needs of the catalytic converter. Since the AdBlue® solution solidifies at temperatures below -11°C, the supply component within the AdBlue® tank is designed to withstand ice formation. The dosing component is completely drained when the engine is turned off.
