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 ...

The key ingredient to maximizing the peak performance of a diesel engine is increasing the amount of diesel being burned. On old mechanical-injection engines, the only way to do this was to modify the ...

High-pressure common-rail injection technology has revolutionized the diesel industry. Over the last decade, it has allowed engine builders to run higher injection pressures (as much as 29,000 psi in ...

At Diesel Specialties we have been working on diesel fuel systems for over 40 years. We are factory trained and authorized to work on Robert Bosch, Delphi, Stanadyne, Zexel and Ambac fuel systems. We ...

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 ...

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.
