Make ABAKUS

The ABAKUS NOx Sensor and Catalyst (134-02-021) is a crucial component for modern vehicle emission control systems. It plays a vital role in reducing harmful nitrogen oxide (NOx) emissions released into the atmosphere. This assembly integrates both a NOx sensor and a catalytic converter specifically designed to work together. The sensor accurately measures the level of NOx in the exhaust gases, providing real-time data to the vehicle's engine control unit (ECU). This data allows the ECU to adjust engine parameters and activate the catalytic converter for effective NOx reduction. The catalytic converter component within this unit converts harmful NOx into less harmful nitrogen gas (N2) and oxygen (O2). By ensuring the efficient operation of this system, you contribute to cleaner air and meet increasingly stringent environmental regulations. This part is engineered for reliable performance and durability.
