Modern trucks rely heavily on precise fuel delivery systems to maintain performance, fuel economy, and emissions control.

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 ...

Turns out the old technology did a few things no computer has matched.

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 ...

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Electronic fuel injection. These three words can strike fear in even the most seasoned automotive technician. The reality, however, is that no carbureted induction system can match the fuel-metering ...

Times are a-changin’, folks. 2010 was twelve years ago, and a lot of the affordable used performance cars available today are more technologically advanced than ever. And none of those technologies ...
