Yes it is common rail diesel, the system work similar to regular fuel injected cars, but at much higher pressures, that CRD does not have what you would think of a normal diesel having an injection pump with a steel tube running to each cylinder. The CRD has a common rail feeding all the injectors the needed pressure.

It stands for "Awesome Jeep Engine". :thumbsup:

 

Though I'm not sure why the letters don't match up. :dunno: Maybe it's in German?

Exactly, rather than old diesels where the fuel injection was completely mechanical in nature(from timing and duration, all controlled mechanically via the IP(injection pump)), which had equal length lines running to each cylinder to an injector nozzle, this system uses electric injectors just like MPFI gassers, with a high pressure common rail feeding all the injectors(like 23,000psi high pressure). The next generation of 2.8L VM engine uses piezoelectric injectors and even higher pressures, something on the order of 36,000psi or so(currently sold in the KK overseas)

I was thinking more along the lines that Jeep was German-owned at the time. :D
