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 ...

The power, fuel efficiency, and longevity of an engine will heavily depend on the fuel that’s being delivered. Furthermore, ...

How does fuel injection work? Everything you need to know about fuel injection! Throttle body injection, multipoint port ...

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 ...

Automakers have long touted the benefits of fuel injection, claiming increased efficiency and power. But as more cars have the system installed (around 73% in 2023), more and more consumers are ...

Lots of new car engines these days are built with both port and direct fuel injection. On the surface, that might not make much sense. Why would a carmaker use two different types of injection methods ...

Every new car sold in the United States today uses fuel injection, but not all fuel injection systems are the same. Some cars use port injection, while others use direct injection. Some even use both.

Gasoline direct injection (DI) engines have been lurking in the shadows of gasoline-burning, internal combustion engine development for decades but are now becoming mainstream. This is all good, as DI ...

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 ...
