It’s rare that we get to see the inner workings of a high-revving engine as it reaches full tick. Most internal combustion motors in regular production cars don’t dare rev past 8,000 RPM, with many ...

The Commander 950 Multi-Point fuel-injection system is a speed-density system (i.e. it does not rely on a mass air flow sensor). It's intended to convert carbureted, non-computerized, small-block ...

Back when Shelby was looking to make its little Cobras go faster, it turned to multiple carburetion in the form of a quartet of downdraft Weber carburetors. Not only did having eight individual ...

It’s a contentious affair that has been ongoing now in hot rodding for roughly 30 years … carburetors versus electronic fuel injection (EFI). There are ardent supporters and vociferous cynics on both ...

Anyone who has gone to school to learn how to repair engines of all types, such as myself, will have learned the fundamentals of how they work. It's crucial for troubleshooting and diagnosing engine ...

A huge component of performance is control. If we can more accurately control the timing of fuel and spark to the engine we will achieve a happier, more powerful engine. For older muscle cars, this ...

Automobile engines have undergone tons of changes over the years, primarily to make them more efficient. For the most part though, engine changes result from a string of iterative improvements on ...

Port fuel injection (PFI) was a major milestone in the early '80s. The integration of PFI rapidly changed the way fuel was delivered by increasing fuel economy and improving engine performance. Even ...

The Komatsu hydrostatic drive uses a high-speed and low-speed motor. When lots of torque is needed, both drives work through the crankcase; but when the machine gets up to speed, a clutch removes the ...

CARS.COM — You’ve heard the term before, but what are the actual nuances of fuel injection? What are the different types of fuel injection in your vehicle? It requires a little bit of basic engine ...

Vehicle fuel injectors are integral to a car's engine fuel delivery system. Fuel injectors are responsible for delivering the right fuel at the right time. Gasoline and diesel-powered engines of all ...
