History
The common rail system prototype was developed in the late 1960s by Mr. Hiber of Switzerland. After that, Ganser of the Swiss Federal Institute of Technology developed the common rail technology further. In the mid-nineties, Dr. Shohei Itoh and Masahiko Miyaki, of the Denso Corporation, a Japanese automotive parts manufacturer, developed the Common Rail Fuel System for Heavy Duty Vehicles and finally turned into its first practical use on their ECD-U2 Common Rail system, which was mounted on the Hino Raising Ranger truck and sold for general use in 1995.

"common rail
Common rail direct fuel injection (CDI) is a modern variant of direct fuel injection system for Diesel engines. It features a high-pressure (1000+ bar) fuel rail feeding individual solenoid valves, as opposed to low-pressure fuel pump feeding pump-nozzles or high-pressure fuel line to mechanical valves controlled by cams on the camshaft. 3rd generation common rail diesels now feature piezo injectors for even greater accuracy, with fuel pressures up to 1700 bar.
History
The common rail system prototype was developed in the late sixties by Mr. Hiber of Switzerland. After that, Ganser of the Swiss Federal Institute of Technology focusing on his research the common rail technology was advanced. In mid nineties, Dr. Shohei Itoh and Masahiko Miyaki, Japanese automotive parts manufacturer Denso Corporation, developed the Common Rail Fuel System for Heavy Duty Vehicles and finally turned into its first practical use on their ECD-U2 common Rail system, which was mounted on the HINO RAISING RANGER truck and sold for general use in 1995. Later in 1997 the German automotive parts manufacturer Robert Bosch GmbH extended its use for passenger car.
Common rail engines have been used in marine and locomotive applications in times past. The Cooper-Bessemer GN-8 (circa 1942) is an example of a hydraulically operated common rail diesel engine, also know as a modified common rail.
With rising fuel prices throughout the 1990s, a number of companies, including Robert Bosch GmbH, Fiat,Volvo and MTU, attempted (separately) to develop new Diesel engines with lower emissions and higher fuel efficiency.
Common rail engines were first used by the Fiat subsidiary Alfa Romeo, and the technology is most commonly used by Fiat, under their MultiJet brandname. The engines are suitable for all types of road car, including small hatchbacks such as the Fiat Panda. "
