Don't let failing oxygen sensors compromise your engine's performance. O2 sensors are critical to emissions control on your car, SUV or truck. As the name implies, the O2 sensor (also called an ...

Scientists have discovered a new way to make molecular oxygen (O2) from carbon dioxide (CO2) -- no green plants involved. Their findings could alter our understanding of the Earth’s early atmosphere ...

Modern vehicles are pretty complicated pieces of tech. Apart from emissions and other vital functions, the engine control system relies heavily on several sensors to regulate performance. That is ...

Earth's atmosphere wasn't always full of life-giving oxygen — it was once a choking mixture of carbon dioxide and other gases, more like the atmosphere of Mars or Venus. It's widely believed that the ...

Our well-worn textbooks might have us believe that the rise of atmospheric oxygen some 2.45 billion years ago --- to levels making complex life tenable over large swaths of this pale blue dot --- is a ...

Learn how to properly install an oxygen sensor (O2) bung in your classic muscle car exhaust system. This step by step ...

Wideband O2 sensors play a pivotal role in the realm of automotive tuning, providing precise measurements of the air-fuel ratio necessary for optimizing engine performance. Unlike their narrowband ...

Today’s climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. By analyzing clues contained in rocks, scientists at the ...
