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 ...

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 ...

Ever wondered which injectors are in your truck, what they look like, or even how they work? Throughout the progression of diesel injection systems, this component has gone from extremely simple to ...

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 ...

To achieve the future emissions regulations with low particulate and Nox levels, both the engine combustion system and the fuel injection equipment will have to be improved. For the fuel injection ...

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 ...

Gregg Petersen's Hilborn-injected Chevette. The first thing you should understand is that direct-port, constant-flow fuel-injection—Hilborns, En-derles, Crowers, whatever—were never designed, nor ...
