The aim of this presentation is to give a generic technical overview of the main features and operating principles of the common rail diesel fuel injection system.

The Bosch Common Rail Injector injects the precise amount of fuel into the combustion chamber at the right time and in the right quantity. This can be actuated with a solenoid on the injector, …

e engine’s oper-ating cycle. Due to our modular design, we are able to offer our common-rail systems fo the most varied engine types. We provide common-rail systems for engine sizes

All Common Rail system components are also inspected intensively by calculation engineers with CFD analyses to model flow efects inside components and incorporate the findings in the design.

Fast-switching solenoid injectors with short injection intervals are central parts of these systems. The CRS2 series is suitable for diesel engines with up to eight cylinders and a wide power and …

In a common rail injection system the fuel is pressurised by a hydrostatic high pressure pump and fed to a ‘common rail’ arranged near the injectors for all cylinders.

Second-generation common-rail systems control rail pressure on the low-pressure side by means of the metering unit (Figs. 1 and 2). The high-pressure pump (types CP3 and CP1H) need only …
