Popular Design for Hino Nox Sensor - High-sensitive Nitrogen Oxygen Sensor YYNO7367 – Yunyi

Advantages of High-sensitive Nitrogen Oxygen Sensor YYNO7367

1. High prevision and sensitivity for calculation of NOx concentration.

2. Quick response and recovery to the problem.

3. Long Lifetime with Srong Reliability & Stability

4. The chip inside is produced by Chemical Etching Method, ensuring the chip’s high-efficiency.

5. Using high-pressure fuel injection technology to reduce PM emissions, making the volume of NOx-emission less than what regulated by most governments in the world.

6. The Nox sensor detects the NOx concentration in the exhaust gas and feeds it back to the ECU, to accurately control the SCR system and finally meet the emission requirements.

7. The chip is strong in reverse surge and low forward voltage drop.

8. Can keep normal running in different environments for longer time than its rivals without sacrificing swift reaction to gas concentration.
