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

Today’s computerised engine control systems rely on inputs from a variety of sensors to regulate engine performance, emissions and other important functions. The sensors must provide accurate ...

AIR, fuel and spark are the three ingredients for a gasoline engine to produce power. Other than an occasional change of spark plugs and plug wires, most newer vehicle ignition systems will operate ...

While in closed-loop (part-throttle) operation, the EEC uses feedback from the car's oxygen sensors to monitor and maintain a "stoichiometric" air/fuel ratio. This ratio of around 14.7 parts air to 1 ...

Modern car engine control systems rely on input from several sensors to regulate the engine’s performance as well as its emissions and other vital functions. When these sensors fail to provide ...

As ever, I am fighting a marginally winning battle against my 1991 Mazda MX-5, and this is the story of how I came to install a wideband oxygen sensor in my Japanese thoroughbred. It came about as ...

An automobile’s fuel-oxygen ratio determines performance as well as its exhaust toxicity, making it essential for vehicle designers to get this mixture right and keep it right over time. A proper ...

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 ...
