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

It's an amazing time when there's new technology in the industry as it forces a new rivalry in speed parts, and direct-injection is firmly in the high-performance arena whether anyone likes it or not.

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 ...

Most modern vehicles have multi-port fuel injection (MFI) with a separate fuel injector for each cylinder. This system mixes the fuel and air together right in the intake port for eachengine cylinder ...

Search the web for 'direct fuel injection history' and two prominent results will often materialise: Leon Levavasseur and the Mercedes-Benz 300 SL. Their prevalence is understandable. Levavasseur is ...

General Motors' use of the latest engine technology to help rebuild its image continues this fall with a powerful new engine for a pair of Cadillacs. The 300-hp, 3.6-liter V6 slated to debut in the ...

The carbureted car and truck era phased out by the early '90s. Carbs are still in use today on a few motorcycles, lawn mowers, and other power equipment, but electronic fuel injection (EFI) is ...

If one fuel injector helps improve engine performance, will two fuel injectors do twice the job? Not exactly. But Nissan Motor Co. thinks doubling the number of injectors will have enough benefits to ...
