принципно да - на фиат е разработката
но
т34 също е с комон рейл дизел:)))

Bosch Common Rail injection system –
Milestones of development
1997:
First Common Rail system in the world for passenger cars.
Injection pressure: 1,350 bar.
First production use: Alfa Romeo and Mercedes-Benz.
Това къде го имплементират първо е друг въпрос....
Ша има бирааааа.
На практика Фиат също разработват такова нещо, но явно се отказват от идеята, въпреки, че изкарват такива коли...

поне квото аз съм чел ФИАТ продават на БОШ патента, за да произвеждат те управляващата електроника
и оттам нататък експертизата на БОШ ражда т.нар EDC али бали дето са ЕКУ-тата на комон рейл дизелите
но къде може да се прочете със сигурност това, не знам :)

And now this research strand has led to the creation of M-Jet engines: another first for the Fiat Group in the diesel engine field. But we had been putting in a lot of hard work behind the scenes since 1986, the date that marked the arrival of the Croma TDI, the first direct injection diesel vehicle in the world.
At that time, this represented a true engineering breakthrough that was later adopted by other manufacturers. Direct diesel injection engines offered better performance and lower fuel consumption but failed to resolve the problem of excessive engine noise at low rpms and while speeding up or slowing down. So work began on a more advanced direct injection system and a few years later this led to the development of the Common Rail principle and the Unijet system.
The idea first came from the Zurich University research laboratories where scientists were working on an injection system that had never before been applied to a vehicle, i.e. the Common Rail system. The idea is simple yet revolutionary. If you continue to push diesel into a tank, the pressure inside will rise and the tank itself will become a hydraulic accumulator (or rail), i.e. a reserve of pressurised fuel ready for use.
Three years later, in 1990, the Unijet system developed by Magneti Marelli, Fiat Research Centre and Elasis on the Common Rail principle entered the pre-production stage. This stage was completed in 1994, when Fiat Auto started to look for a partner with superlative knowledge of diesel engine injection systems. The final stage of the project, i.e. completion of development and industrial production, was eventually entrusted to Robert Bosch.
Now our story has reached 1997 and the launch date of the Alfa 156 JTD with its revolutionary turbodiesel engine. Compared to conventional diesel power units, the JTD guarantees an average improvement in performance of 12% together with a 15% reduction in fuel consumption. These results meant that cars fitted with the engine were an immediate hit.
Now the time is ripe for the second generation of JTD engines, the M-Jet and multivalve units: in 2002 with the 1.9 M-Jet 16v (forerunner of this new family of multipoint injection engines) in 2003 with the 1.9 upgraded to 150 bhp for the Alfa GT and the 129 kW (175 bhp) 2.4 JTD Multijet 20v available on Alfa 166, Alfa 156 and Sportwagon models.
Признавам.. ша пиеш бира....
Бреййй тез 'талианци... освен спагети и в дизелите се намешаха :)
Факт, е че те първи са го разработили, а Бош доколкото знам успоредно с тях също са правили разработка... ама... явно не е успял.
