Schaeffler starts European series production of NOx sensors for gasoline vehicles ahead of EURO 7
Schaeffler has begun series production of NOx sensors for gasoline vehicles in Europe, giving automakers a tool to meet tightening emissions standards such as EURO 7.

What Happened
Schaeffler has started series production of its NOx sensors for gasoline vehicles in Europe. The company says the move helps automakers comply with future emissions standards such as EURO 7. The gasoline sensor is based on the technology of Schaeffler's diesel version, which the company says has established a leading position in the market. The start of series production is intended to strengthen Schaeffler's position as a technology partner for low-emission, future-ready powertrain systems.
“The start of production of our NOx sensors contributes to one of Schaeffler's fundamental goals: delivering reduced emissions regardless of powertrain type. We also see sensor technology as a strategic growth opportunity and are systematically expanding our capabilities in this area. In this case, the goal is to offer vehicle manufacturers precise, intelligent, and scalable solutions for efficient and reliable emissions control.”
EURO 7 significantly tightens the requirements for vehicle emissions control. The standard addresses not only compliance with limit values during testing but also real-world emissions during driving, the durability of vehicle systems, and their performance over the vehicle's entire life cycle. For vehicle manufacturers, that means the engine and the exhaust after-treatment systems must work together reliably and precisely under a wide variety of operating conditions.
“Our NOx sensors provide the necessary transparency around exhaust lines and help our customers design their systems for precision and future-proofness. The NOx sensor for gasoline vehicles is based on the technology used in our successful diesel version, which has established a leading position in the market. We are thus applying our proven technological capabilities to another key area and creating a solid foundation for meeting the requirements of future emissions standards.”
The sensor is designed to meet the demands of real-world driving conditions and to ensure reliable operation throughout the vehicle's entire life cycle. It continuously measures the amount of nitrogen oxide actually emitted from the vehicle and generates an electronic signal that correlates with the nitrogen oxide concentration in the exhaust gas. It also generates a lambda signal indicating the oxygen content in the exhaust gas. The combination of these two parameters allows precise assessment of exhaust gas composition and reliable emissions monitoring over extended periods.
- The sensor signal can be used to control exhaust after-treatment, letting the system respond immediately to changes and precisely control emissions under a variety of operating conditions.
- Depending on the system architecture, it can reduce the required catalytic converter size and precious metal content.
- It can eliminate the need for additional lambda sensors.
- It helps reduce the complexity of the overall system.
Why this matters
EURO 7 tightens vehicle emissions control and also covers real-world driving, system durability and performance over a vehicle's whole life cycle, so engine and exhaust after-treatment hardware must work together precisely. Automakers facing those rules are the customers for this sensor, and Schaeffler says the production start strengthens its role as a technology partner for low-emission powertrain systems while opening a strategic growth area for the supplier.
