What are exhaust gas sensors for automotive emission control?
What are exhaust gas sensors for automotive emission control?
This report gives an overview on ZrO 2 automotive exhaust gas sensors, the development steps of thimble-type oxygen sensors and the technology and design of planar-type oxygen sensors. Furthermore, advanced exhaust gas sensor systems, catalyst monitoring sensors and future developments are described.
When did they start using exhaust gas sensors?
Their triumph began in 1976 after the announcement of stringent emission regulations in California and the demonstration that controlling the air–fuel ratio with an oxygen sensor in conjunction with a three-way catalyst can significantly reduce these emissions [1], [2], [3].
Why are oxygen sensors critical to passing emissions?
Oxygen Sensors Are a Critical Key to Passing Emissions Automotive exhaust emissions are everyone’s concern because we all breathe the same air. 50 percent of Americans live in areas that exceed national clean air standards. Reducing tailpipe emissions, therefore, is a top priority in the effort to fight air pollution.
Are there any ultra low emission vehicle sensors?
This triggered the development of a new generation of fast light off (FLO) sensors. While low emission vehicle (LEV) regulations could still be met by 30–60 s, ultra low emission vehicle (ULEV) regulations already required ≤15–20 s and system currently underdevelopment ≤10 s.

Why does my car make a ticking noise when I Turn on the engine?
If the noise goes away, it’s most likely an exhaust leak. If it remains, then oil pressure is the likely culprit. Exhaust manifold leaks can be caused by a blown gasket, loose or broken manifold bolts or studs, or even a cracked manifold.
What does the oxygen sensor in your car measure?
The oxygen sensor in your vehicle measures oxygen levels in the exhaust gases exiting the engine.
