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 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 ...

There are many advantages that make 5.9L Cummins-powered '98 1/2 to '02 Dodge Rams very desirable trucks—especially from an engine standpoint. First, the engines don't have the killer dowel pin ...

To save time and money, you might want to learn how to clean fuel injectors without needing to rely on professionals. But do ...

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 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 ...

Fuel injectors are the heart of a vehicle’s fuel system. Because they keep the fuel supply running smoothly, when an injector experiences a problem, the whole engine suffers the consequences. Because ...

The power, fuel efficiency, and longevity of an engine will heavily depend on the fuel that’s being delivered. Furthermore, an engine’s efficiency is dependent on a precisely calculated air-to-fuel ...

We have investigated the fundamental characteristics of unit injectors and pump-line-nozzle systems theoretically by a graphical analysis of characteristic lines. We have confirmed the higher ...
