With a common-rail injection system, high-pressure fuel is pumped through and stored in a rail that feeds many injectors at once, instead of through a pump that directly feeds an injector. The ...

This common-rail fuel pump was created by Fiat's subsidiary, Elasis, and was successful at addressing the noise issue raised by Bosch's injection pump. However, Fiat would sell the common-rail ...

Siemens VDO supplies piezo-actuated injectors for common-rail systems. In a Pumpe-Duese engine, a pump injector at each cylinder produces a fine spray of diesel fuel for more efficient fuel ...

Fuel is supplied to the high-pressure fuel rail by a high-pressure supply pump. Depending on rpm and engine load, the pressure in the rail can exceed 30,000 to 40,000 psi.

Diesel fuel from the injection pump enters the mechanical injector body and starts to build pressure. Once the pressure is high enough (about 4,000 psi), a check valve in the injector is lifted ...

All Cummins ISX engines have the XPI common-rail injection system, which uses a crankshaft-driven pump to keep the fuel rail – seen of the left side of this 11.9L ISX – pressurized to more ...

2. The pressure of the fuel in the common rail is dependent on engine speed because fuel pump is driven by engine itself. Thus, more the speed of engine, more the fuel is pressurized by the pump. 3.

Bosch CP4 Fuel Pump Failures Common Rail diesel fuel systems began appearing around the turn of the 21 st century as a means to offer drivers robust output while still meeting evolving emissions ...

Instead a single output pump supplies a fuel “rail” – a reservoir of fuel held at pressures of between 400 and 1400 bar (5800 – 20,300 psi) – “common” to all the injectors. How it works: ...

* Says its unit Yaroslavl Diesel Equipment Plant has started serial production of electronically controlled high pressure fuel pumps for YAMZ-530 family engines meeting the Euro-5 emission standard ...
