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.

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 ...

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 ...
