Talk:Ford Duratorq engine

From Wikipedia, the free encyclopedia

Copied from my talk page (I thought it would be better placed here):

First, the DLDs aren't generally non-intercooled. The 1.4L engine is non-intercooled, but only in the regular turbo 8-valve version. The 90/92PS 16-valve design is intercooled and uses a variable nozzle turbo, but it'll disappear soon as it can't pass Euro 4 emission regulations. The 1.6L is only available in intercooled 16-valve VNT form. The 1.8L isn't related to this design at all, it's an update of the Endura engine.

Then, there's a big mess with the ZSD design applications. First, the 2.0L 8-valve 90/110PS versions as found in several Citroen and Peugeot models are 100% genuine PSA designs, part of the Peugeot EW/DW family, and predate the Ford/PSA partnership. The 136PS 16-valve version is a ZSD but uses the same cylinder casings (85*88mm) as the Peugeot, hence the confusion.

Next, the 2.0L used in the Transit and Mondeo is not the same engine as the Ford/PSA cooperation, it's a different design with 86*86mm bore and stroke, it debuted in passenger cars with the current Mondeo and predates the Ford/PSA partnership.

The 2.2L PSA/Ford has yet to make its debut, it'll happen around mid-2006. The Peugeot/Citroen models use the Peugeot DW12 engine (2179cc, 85*96mm), and the Mondeo and Jaguar X-Type use an enlarged version of the Transit/Mondeo engine (2184cc, 86*94mm), so they're completely unrelated. The 2.4L is based on this design and not part of the Ford/PSA partnership either.

Speaking of Peugeot engines, I managed to find info on the modern families of Peugeot engines (X, TU, XU, EW/DW and ES). I'll add them saturday. --Pc13 00:35, 30 December 2005 (UTC)

Thanks for the corrections, Pc13 (talk · contribs)! I'm just doing detective work on this engine family so I really appreciate a knowledgeable person's help. I was interested in the novelty of a shared engine family. It is odd that unrelated engines share the exact same displacement - perhaps Peugeot contributed the block design? --SFoskett 15:07, 30 December 2005 (UTC)

They don't have the exact same displacement, but it comes pretty close. 85x88mm makes for 1997cc, and 86x86mm for 1998cc. It's not explicit in the press-release, but I believe for the 2.0 L engine they decided on keeping the PSA cylinder casings because the tooling at the Douvrin factory was already made for it. Interestingly, there will be two 2.2 L designs in the PSA/Ford partnership. Passenger models will use the 2179cc (85x96mm) PSA displacement, but LCVs will use a new 2198cc (86x94.6mm) displacement. The PSA engine can't be used in RWD vehicles, whilst the Ford Transit block can. --Pc13 15:51, 30 December 2005 (UTC)

OK I did some work on this as you can see. I created the List of PSA engines stub and the PSA EW/DW engine page. More obviously has to be done! --SFoskett 15:59, 30 December 2005 (UTC)

I think we will have to split out the Duratorq families into different pages and use this as a disambiguation page like PSA HDi engine. --SFoskett 16:02, 30 December 2005 (UTC)

What should we call the split pages? Ford DLD engine or Ford/PSA DLD engine? And is the ZSD the name of the JV engine or just the Ford? --SFoskett 16:04, 30 December 2005 (UTC)
