The diesel industry uses two basic styles of mechanical injection pumps: the inline and rotary. In most applications, the inline pumps are attached to inline engines (due to packaging), while the ...

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 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 ...

and was designed to offer a more consistent method of delivering fuel. How does mechanical fuel injection work? Early mechanical fuel systems typically relied on a complicated fuel pump that would ...

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 ...
