The basic difference between direct injection (DI) and the port-fuel injection (PFI) systems we've become familiar with since the mid-1980s is that PFI sprays fuel into the intake manifold (behind ...
If you flip through the list of features on just about any new car or truck, you’re likely to see the words “direct fuel injection,” or DI. The concept is straightforward enough -- engineers have ...
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 ...
Direct-injection engines are pretty common in new cars these days, but how exactly do they work? Well, this explainer video put together by the YouTubers at SavageGeese gives us an in-depth look at ...

Why some engines have both port and direct injection
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 ...
