NOx sensors & exhaust gas control
To improve the climate and make it more environmentally friendly, all car manufacturers are developing, testing, and producing complex exhaust systems. Advanced diesel and gasoline combustion engines ensure a clean environment. A major feat in development.
The exhaust system, consisting of numerous sensors, sensitively measures the environment and the current operating and load status of your vehicle.
The at autoteile germany NOx sensor (nitrogen oxide sensor) monitors nitrogen oxides in exhaust gases. With our at autoteile germany sensor range for exhaust gas pressure, differential pressure, exhaust gas back pressure, and exhaust gas temperature, you can continuously and accurately signal the operating status of the combustion gases to the engine control unit. Whether in city traffic, on the highway, or in the mountains at full throttle. at autoteile germany sensors stand for a perfect fit, finely tuned signal technology with precise information for a clean environment.

EGR module
Efficient exhaust gas recirculation
The EGR module precisely controls the recirculation of exhaust gases into the combustion chamber in order to optimize combustion and reduce emissions. The integrated design combines the valve mechanism, sensors, and control system in a compact unit.
Integrated control technology
Thanks to its modular design, the EGR module responds flexibly to changing engine loads, ensuring consistent combustion. The modern control unit contributes to improved engine performance and efficient fuel consumption.
Pressure transducer, exhaust gas control
Precise pressure signal conversion
Pressure transducers measure changes in pressure and convert them into precise electrical signals. These signals are important for controlling the exhaust system accurately. Thanks to their fast response, the system settings can continuously adapt to different operating conditions.
Optimized exhaust gas control
The exhaust gas control system uses these precise signals to dynamically regulate the exhaust gas flow and reduce emissions in the long term. Intelligent algorithms ensure that the system always operates optimally, even under changing loads.
Cooler, exhaust gas recirculation
Efficient temperature control
The cooler specifically reduces the temperature of the recirculated exhaust gases, thereby stabilizing the combustion process. This precise cooling minimizes the formation of nitrogen oxides (NOx) and contributes significantly to reducing pollutants.
Optimized system integration
Engine performance is optimized by introducing cooled exhaust gases into the combustion cycle in a targeted manner. This enables a harmonious balance between low-emission combustion and fuel-efficient operation, which increases the overall performance of the powertrain.
Sensor, exhaust gas temperature
Accurate temperature measurement
The sensors measure the exhaust gas temperature with maximum precision and provide important data for fine-tuning the combustion process. This optimizes engine operation and increases efficiency.
Reliable system monitoring
Thanks to fast response times, the sensors adapt flexibly to changing operating conditions. They help reduce emissions and support environmentally friendly, stable operation.
Sensor, exhaust pressure
Accurate pressure measurement
The exhaust pressure sensors measure the pressure in the exhaust system with maximum accuracy and provide essential data for engine tuning. This allows control strategies to be precisely tailored to current operating conditions.
Dynamic system adaptation
The data collected helps the engine to flexibly adjust exhaust gas purification. This reduces harmful emissions while maintaining an optimal balance between performance and environmental friendliness.
Injection unit, soot/particulate filter regeneration
Precise fuel metering
The injection unit precisely controls the fuel supply, enabling optimal combustion. This improves engine performance and efficiently regulates fuel consumption.
Targeted filter regeneration
Controlled injection triggers a regeneration process in the soot/particulate filter, which breaks down accumulated particles. This extends the service life of the filter and ensures that exhaust gas purification is carried out in an environmentally friendly and sustainable manner.
Heating, tank unit (urea injection)
Optimal system temperature control
The heating system keeps the urea solution fluid even in freezing temperatures and prevents it from solidifying. This ensures continuous operation of the injection system, which is essential for the regeneration process of the particulate filter.
Precise dosage control
The tank unit measures urea consumption and precisely regulates the injection quantity in the exhaust gas stream. In this way, it optimally supports SCR technology and makes a decisive contribution to reducing nitrogen oxide emissions.
MoreAdBlue pump
Efficient AdBlue dosing
The AdBlue pump ensures precise and continuous delivery of the urea solution to the exhaust system. Its precise control supports SCR technology and enables effective reduction of nitrogen oxide emissions.
Robust system stability
Thanks to modern technology, the pump ensures consistent operation even under demanding conditions. This ensures the long-term functional reliability of exhaust gas purification and optimizes fuel consumption.

Tank Unit, Urea Injection
Precise AdBlue Supply for Maximum Efficiency
The tank unit ensures safe storage and demand-based delivery of the urea solution. As the core of the AdBlue system, it provides a constant supply to the urea injection system and supports efficient SCR exhaust gas treatment.
Fewer Emissions. Greater Reliability.
A high-performance tank unit is essential for the reliable reduction of nitrogen oxides (NOx). High-quality components ensure trouble-free operation, help prevent failures in the AdBlue system and contribute to compliance with modern emission standards.
MoreAdBlue Feed Pump (Feed Unit/Dosing Pump)
Constant Supply for Effective Exhaust Gas Purification
The AdBlue feed pump delivers the urea solution from the tank to the injection unit with precise control and at the required operating pressure. This ensures that the SCR system is reliably pressurized with AdBlue in every driving situation from cold starts to full load for consistent and demand-based dosing throughout the vehicle’s entire service life.
Reliability as a Prerequisite
Only a flawlessly functioning feed pump ensures stable system pressure throughout the entire SCR circuit. Since the pump is in constant contact with a corrosive, crystallizing liquid, it is subjected to particularly demanding conditions. A failure inevitably leads to a loss of pressure, error messages in the exhaust system, and, as a result, a noticeable reduction in power or even the vehicle being shut down by the engine control unit.
MoreAdBlue Injection Unit (Dosing Module/Injector)
Precise Dosing for Clean Exhaust Emissions
The AdBlue injection unit precisely doses the urea solution into the exhaust system upstream of the SCR catalyst. This reliably converts NOx into nitrogen and water and is precisely calibrated for every load condition.
Safety in an Emergency
Only a fully functional injection unit ensures reliable compliance with emissions standards. Scale buildup, crystal formation, or a defective nozzle can lead to error messages, reduced performance, or in the worst case—a driving ban imposed by the engine control unit.
