When we got the invitation to tour Bosch's oxygen sensor plant in Anderson, South Carolina, it had all the allure of eating a sand sandwich. Let's face it, oxygen sensors aren't the most glamorous ...

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

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 ...

As performance enthusiasts and racers work with more sophisticated tuning tools—especially those designed for EFI engines—there's a growing debate on whether to use air-fuel ratio or Lambda in the ...

Back in the Fox days, the most common method of tuning was to increase timing until detonation, and back it off a couple degrees. Like Fox cars, that method was crude, but a dyno wasn’t on every other ...

This is a preview. Log in through your library . Abstract The method for measuring air-fuel ratio is generally based on analysis of the exhaust gas components and its calculations. A new instrument ...

High bandwidth control of the air-fuel ratio is necessary in order to minimize the exhaust emissions of sparkignition engines with three-way catalytic converters. A new approach is to implement a ...
