The fuel injection pump is the heart of the diesel engine. Precisely delivered fuel maintains a rhythm or timing that keeps the engine running smooth. Simultaneously, the pump also controls the amount ...

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 ...

Mechanical injection systems rely entirely on engine driven components to meter, pressurize, and time fuel delivery. In these engines, a mechanical injection pump is driven by the engine's gear train ...

If you browse forums often, chances are you've come across some heated discussions around the CP4 fuel pump. The CP4, short for "Common Rail Pump 4," is a high-pressure fuel injection pump that made ...

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 ...

A huge component of performance is control. If we can more accurately control the timing of fuel and spark to the engine we will achieve a happier, more powerful engine. For older muscle cars, this ...

Picture an old windup desk clock. Now cross it with a gasoline engine, adding a tiny crankshaft and pistons. Tack on a few Buck Rogers bits, so it looks like Rube Goldberg's toaster. Flow gasoline ...

Bosch launched the first common rail system in 1997. The system is named after the shared high-pressure reservoir (common rail) that supplies all the cylinders with fuel. With conventional diesel ...
