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 ...

If you think direct-injection diesel engines made their debut in the 1980's, think again. The first diesel without extra ...

So we wake up one day and decide we want to throw a supercharger on the C7, and while we are there let’s throw a cam in it, too! The supercharger is an air pump in front of the air pump and its ...

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 ...

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 ...
