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 ...

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 ...

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 ...

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 ...

High pressure common rail system can precisely control the injection time and injection pressure to improve the thermal efficiency of the engine. The injection characteristics of the system can affect ...
