If you build engines, tune cars, or even just like mashing your foot on the throttle with conviction, you’ve probably heard ...

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 ...

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 ...

An engine relies on two things to run: spark and fuel. Sure, there are a million other things to consider when speaking of engine operation and power, but regardless of the type, size, or brand of ...

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 ...

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 ...

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 ...
