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 ...

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 ...

Mechanical injection systems rely entirely on engine driven components to meter, pressurize, and time fuel delivery. In these engines, a mechanical injection pump is driven by the engine's gear train ...

Electronic fuel injection is older than you think, the earliest example being the failed Bendix Electrojector system from 1957. Bosch bought the rights to the Eletrojector system and developed it into ...

Most new petrol cars you see today are equipped with fuel injection systems or injector motors. These have almost wholly supplanted older carburetor motors. They are more reliable, effective, and ...

We often talk about the benefits of fuel injection on off-road vehicles. Generally, these systems run more reliably than carbureted systems, but they are, at the end of the day, a bit more complex ...

Having fuel injectors on all mass-produced vehicles is one of the biggest automotive breakthroughs of the past few decades. If you've ever gone through having to start an engine with a poorly tuned ...

Over time and miles, your car might start to slow down. It might not accelerate as quickly as it once did; the engine may not run as smoothly as you remember, or the fuel economy may dip—but ...

The first thing you should understand is that direct-port, constant-flow fuel-injection—Hilborns, En-derles, Crowers, whatever—were never designed, nor intended, to be run on the street. All of these ...

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 ...
