The clearances inside diesel injection system parts are closer than those found in any other technology. The plungers and needle valves in injectors need to fit tightly to ensure precise metering and ...

High-pressure common rail fuel (HPCR) systems are standard on nearly every diesel engine today, from heavy equipment to over-the-road trucks, light-duty trucks, large generators and more. HPCR fuel ...

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 ...

Diesel injectors have gotten increasingly complex over the last twenty years of diesel development, but their basic design is fairly simple. Diesel fuel from the injection pump enters the mechanical ...

Aren’t the Duramax (left) and 5.9L Cummins common-rail (right) injectors from Bosch similar looking?...The solenoids and upper bodies of the injectors are the same. The returns appear to be the same, ...

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 ...

The common-rail fuel injection system does away with a timed injection pump. Instead a single output pump supplies a fuel “rail” – a reservoir of fuel held at pressures of between 400 and 1400 bar ...
