Function of oxygen sensor：
Oxygen sensors are used to detect the oxygen content of mixture after the air and fuel mixed combustion in the automotive engine.
The oxygen content with electrical signals is then fed back to the engine electronic control unit (ECU).
ECU adjusts the engine’s air and fuel ratio according to the signals of oxygen sensor, thereby improving the engine’s performance, saving fuel and reducing emissions.
Product advantages：
Owned R&D capabilities independently of the core components：
Now we have mastered the whole-process manufacturing technology of core components of thimble oxygen sensors, planar oxygen sensors, wide-band oxygen sensors and A/F rate sensors (AFR).These technologies of advanced oxygen sensor are in the leading in China.
High-quality raw materials, with independent formula：
High-quality raw materials are sourced from the same supplier which supplied material for the world renowned brand oxygen sensor factories. We conduct control starting from the source, so that life and performance of oxygen sensorare effectively guaranteed.
We possess the capability of formulation design and preparation of various kinds of slurries required for element manufacturing of oxygen sensor.We have accumulated rich experiences in R&D of core components,to better provide a solid foundation for new product development in the future.
Plasma spraying technology：Zirconium tube protection layeradopts plasma spraying technology, which has the following.
advantages：
1、The automatic spraying equipment makes the coating more evenly distributed, and improves the product performance；
2、The temperature of spray flame reaches more than 10,000 degrees, which increases the bonding strength between the protective layer and the zirconium body, thereby improving the product life.
