Robert Bosch GmbH -one of the biggest German industrial concerns. Bosch products are on high reputation worldwide. Bosch is known on its innovations and high demands on quality.
Bosch Group is leading global manufacturer in car and industrial technology area, products of wide consumption and building technologies. Bosch group consists of Robert Bosch GmbH company and their 300 district companies and regional companies in more than 50 countries. Bosch yearly extract more than 3 billion of Euros for research and development and in 2006 it declare more than 3000 gadgets worldwide. Company was established in 1886 in Stuttgart Robert Bosch (1861 – 1942) under title "Workshop for precise mechanic and electric engineering" and today sectors of Bosch Group includes manufacturing, sale and post- sale service network with 300 districts and more than 13.000 service centers in more than 140 countries, what provides conditions for further development.

Bosch Group is devided in three business areas:
• equipment for business vehicles
• industrial techniques
• technique in buildings

From offer is extracted Systems for fuel injection control for commercial vehicles
In system for fuel injection control are included all components which transfers fuel from tank in to the combustion chamber.
Low pressure pump pumps fuel from tank in supply chamber of high pressure pump.
High pressure pump compresses fuel.
Mechanically or electronically regulated valves dosing compressed fuel in real time in the engine.
Fuel is over injection nozzles injected in to the combustion chamber.

Common Rail system for commercial vehicles
Common Rail is system for injection with tank.
Difference in relation to all other injection systems: pressurising and injection are independent from each other.

On that way Common Rail system enables bigger flexibility for injection system adaption what gives demand in the view of each specific application.It serves as a base for development of very dinamic, extremely quiet and economical engines.
High pressure pump transfers fuel in high pressure tank (Rail). Fuel there, under pressure which is adequately for explicitly engine working state, stays ready for injection.
Drivers command is transfer over command shoe. Electronically command machine registers that driver command and drive stage and on base of characteristical area calculates necessary fuel pressure, injection period (also and fuel weight) and injection moment. In each engine cylinder is situated one injector with integrated magnetic valve. Opening and closing of magnetic valve determinates beginning and end of the injection.
