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 ...

As we entered into 2014, the industry was abuzz with the acronym “GDI,” otherwise known as Gasoline Direct Injection. The “gasoline” distinction is significant because direct injection has existed in ...

Funded by PERC and conducted by Katech Engineering, the project used software as well as specially designed hardware from Stanadyne to help overcome vapor lock. The results of a recent research ...

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 ...

Common Rail Direct Injection is a very effective technology for diesel engines as it leads to better fuel efficiency, less vibrations and noise, reduced emission levels and many other technical ...

Direct injection, as the name suggests, refers to a type of fuel system which introduces fuel directly into an engine's combustion chambers. This differentiates it from conventional injection systems ...

Assuming you have gotten past the concept that fuel is now shot directly into the combustion chamber, let’s talk about what happens next. The chamber on a Gen V engine has been designed with over a ...

Diesel engines operate at higher compression ratios than gasoline engines, and fuel is injected under much higher pressure. An injection pump, usually driven by a belt or chain linked to the ...
