Re: 2014 diesel production

I am a bit confused here. Just out of curiousity, is the North American version of the diesel slightly different than those for export? I read some technical information saying that Jeep doubled the pressure for the common rail. Is that for all markets?

Rail pressure is the same. Similar specs. The production export looks like it was 10hp higher but????

The real difference is DEF fluid. (Urea injection).

There may still be a revision in the production spec of the Diesel.

Re: 2014 diesel production

FWIW, Motor Trend picked the Summit Diesel over the Cayenne and all other diesels... think they may also have mentioned that the engine is a well proven truck engine and that Gale Banks and the US Military may be consuming a lot of production of same as well...

Re: 2014 diesel production

You just cannot get the 9-speed and Diesel in the same car. Typical media.

I don't know much about these diesels but I know that they are made by VM Motori. I don't know how much of the engine is controlled by a computer. I don't know how much tuning happens electronically. I don't know the range of control Jeep / Chrysler though programming has on the combustion. I also don't know how much of the operation of the engine has to change in the U.S.A. I am curious about these things. But, I won't be anymore the moment I order a HEMI®.

In Common Rail Diesel engines, the fuel pressure in a distribution rail is between 15,000 psi and 29,000 psi the later the Generation of Diesel Engine the Higher the pressure.

This is from Motor Trend:

Quote:
For North American duty, the VM Motori engine, built in Ferrara, Italy, has received a water cooled turbo and increased rail pressure of 29,000 psi.
Read more: 2014 Jeep Grand Cherokee Diesel First Drive - Motor Trend
Until your post I had not remembered reading this. According to this, if it is correct, the engine for North America will be different than the ones used in other markets. If the engine operates at a different rail pressure in North America than in Europe or Australia than I would say that was significant.

To me the statement Motor Trend has made would suggest this. That doesn't mean the statement is unintentionally misleading.

Update: After reading elsewhere the statement appears at least partly false:

The Specs for the VM Motori 630T have the Rail Pressure at up to 29,000 psi the Turbo Charger is also Water cooled across the board. So it would be accurate to say that For North American Duty the engine has the same maximum Rail Pressure. The Part about the water cooling is definitely false. However, based upon a schematic of a Common Rail Fuel injection system it might be possible to adjust the pressure electronically. The ECU("Engine control unit") shows an electrical connection to the pressure limiter in the generic diagram I looked at on Wikipedia. File:Common Rail Scheme.svg - Wikipedia, the free encyclopedia

Re: 2014 diesel production

The statement from Motor Trend is correct but the Overseas models also got the upgrades. At the time it was completely correct as we would have received ours months ahead.... no comment.

They will be plug in tuneable similar to the VMs that the guys down under are already running tmk.

The VM Motori 630 has always had a maximum Rail pressure of 29,000 psi. So what is the difference between the 2013 630 and the 2014 630? That is, what are the upgrades VM Motori made to the engines?

Now this I don't actually know. They were running the lower power versions originally listed. I have no idea why they switched but the new models over seas are slightly more powerful than they used to be.
