Efficient exhaust gas purification for your truck
Urea injection, often also known as the AdBlue system or SCR technology, is at the heart of modern exhaust gas aftertreatment in commercial vehicles. It drastically reduces the emission of nitrogen oxides (NOx) and ensures compliance with strict emission limits. Precise control of the urea dosage is essential for the longevity of the catalytic converter. At FZB Fahrzeugbedarf you will find all relevant components for urea injection – from the robust AdBlue pump to highly sensitive NOx sensors. Our spare parts in OEM quality guarantee error-free communication with the engine management system and prevent costly downtimes due to defective exhaust systems.
Reliable spare parts for all components
Our range covers all elements of urea injection: Dosing modules, feed modules, injection valves, filters, sensors, control units and tank units. All components impress with their high precision, durability and temperature resistance. Thanks to the exact fit of the spare parts, you can quickly maintain or repair your SCR system, minimize downtimes and ensure the full performance of your truck.
What should you look out for when buying:
From the pump to the NOx sensor: precision for exhaust gas purification
A functioning urea injection system consists of a large number of complex individual parts. The AdBlue pump conveys the urea solution from the tank to the dosing unit, which injects the exact quantity into the exhaust gas flow. Sensors play a decisive role here: NOx sensors continuously monitor the nitrogen oxide concentration before and after the catalytic converter. At FZB, we rely on components that have been specially developed for the thermal and chemical requirements in trucks. Regular filter maintenance and the use of certified components prevent the nozzles from becoming encrusted and ensure long-lasting performance.
Avoid error messages: Maintenance of the urea injection system
Defects in the urea injection system often lead directly to a reduction in engine performance in modern commercial vehicles. Common causes are defective heating elements in the AdBlue tank (frost protection), clogged injection valves or failed feed modules. As the system reacts very sensitively to contamination, the use of high-quality filters and precisely fitting lines is essential. By replacing worn components with our tested spare parts, you can ensure that your vehicle passes the emissions test without any problems and that fuel consumption remains stable thanks to an optimally functioning SCR system.
