With the thimble element of oxygen sensor and heater, it will improve the performance of oxygen sensors which can meet the EURO III emission standards, and some models can meet EURO IV emission standards.
With the non-heating design for saving energy and miniaturization, as well as being high temperature-proof, waterproof and vibration-proof, which can work in harsh conditions and environments and meet basic emissions requirements.
The special structure design is adopted, to realize shorter light-off time and faster response, which can meet Euro IV emission standards.
