FIGURE 1—Here's the relationship between air flow through a venturi and how atmospheric pressure "pushes" fuel into the air stream. At the vena contracta, actual pressure is at a minimum (maximum flow ...

The air flow meters are usually used to measure the volume of intake air passing into the automobile system. The capability to detect and measure both backward and forward flow with equal sensitivity ...

Tuning a carburetor to supply an engine with the correct jetting-air/fuel mixture has always been a job that almost impossible for most hot rod owners and tuners. In the past, most performance engine ...

When we hear the words “pitot tube,” we tend to think more of airplanes than of air ducts, but [Franci Kopač]’s guide to pitot tubes for makers shows that they can be a remarkably versatile tool for ...

Once upon a time an engine needed three things to run: fuel, air, and fire. That's what carbs, coils, and distributors are for. Modern EFI engines still need these three elements, but they use ...

Your engine needs a steady stream of clean air to function properly, and it's the job of the mass air flow (MAF) sensor to measure and regulate the amount of clean air entering the intake. The engine ...

Engineers who need to reduce the energy cost of air compressor systems will find the precision ST50 Air Flow Meter from Fluid Components International (FCI) helps them more accurately measure ...

Session 3 covers the crucial equations related to fuel and air management based on the MAF (Mass Air Flow) sensor. These formulas are essential for optimizing engine efficiency and performance.

Here is an introduction to the low cost anemometer (wind sensor) from Modern Device (http://moderndevice.com) . This small sensor suitable for electronic experiments ...
