The function of the oxygen sensor is to measure the information of whether there is excess oxygen in the exhaust gas after combustion of the engine, that is, the oxygen content, and convert the oxygen content into a voltage signal and transmit it to the engine computer, so that the engine can achieve closed-loop control with excess air factor as the goal; Ensure that the three-way catalytic converter has the maximum conversion efficiency for the three pollutants of hydrocarbon (HC), carbon monoxide (CO) and nitrogen oxides (NOX) in the exhaust gas, and maximizes the conversion and purification of pollutants.
Simply put, the oxygen sensor is a detection tool to detect whether the vehicle exhaust emissions exceed the standard.
Hubei Tianbang Autoparts Ltd. started up manufacturing oxygen sensors since 2006. Later we set our goal for developing and innovation of new products by introducing cooperating program with Huazhong University of Science and Technology. The R&D team later developed our other products for a more diverse product line including Nox sensor, EGT sensor, ignition coil and others. Furthermore, base on the R&D team we started exporting trading to challenge global market. With our passionate and obsess with quality control we have been growing for years and thrive for markets all over the world. 
1. Industry certificate: IATF16949, CE;
2. Complete products, 99% of the world's models of oxygen sensors are produced, and there are more than 2,000 product models;
3. Master the core and check the quality from the source. The core components of the oxygen sensor, the zirconium tube and the chip core, are independently produced by our company, and the raw materials (zirconium powder, platinum paste, etc.) are imported raw materials, and adhere to the principle of quality first;
4. The inspection is fine, all products need to go through 100% inspection, the inspection items include: air tightness test, signal sensitivity test, engine simulation loading test, pressure test, salt spray test, etc., to ensure that each one is a high-quality product;
Our service don't stop at the moment we sell our product, until the warranty wares off. For any delivery method except EXW, we will contact logistic company until the product is delivered to the destination forwarder/customer.
