We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are ...

Once again, we asked a question, and the Hagerty community delivered the goods. We all have a shared experience with automotive upgrades, and it seems that I am not alone in regretting some of my ...

If there is an OEM EFI solution for your engine, you should probably start there. If no such system exists or is prohibitively expensive, or if you just love punishmen, read on. Somewhere to put your ...

If you build engines, tune cars, or even just like mashing your foot on the throttle with conviction, you’ve probably heard the term “wideband O2 sensor” being thrown around at the track, dyno ...

Oxygen sensors detect the amount of oxygen in the exhaust. Oxygen sensors usually don’t have a replacement schedule. A bad oxygen sensor can be diagnosed with a code reader or scan tool. A car’s ...

We may receive a commission on purchases made from links. While it may seem intimidating at first, there are plenty of easy DIY auto maintenance projects that even the most novice DIY-er can handle.

Piezofluorochromism, the phenomenon of materials reversibly changing their fluorescent color when pressure is applied, is ...

Abstract: Emerging portable applications, including human activity recognition and robot navigation, require always-on sensing technologies to continuously monitor the environment. Continuous sensing, ...

Abstract: Aiming at the demand of oxygen partial pressure measurement in aerospace and aviation, a tunable diode laser absorption spectroscopy (TDLAS) technique is proposed to realize the oxygen ...
