Wasn't lower pressure what Krebs, or was it Jodl recommended to the leader?693Views0likes0CommentsRe: Ford's answers to the NHTSA 6.7 Investigation

Here's a link to some raw data failures of number of replaced HPFP's in VW's, by area, by state, by date.Excel file of failures There's a sh*t ton of these failures, and the data is missing for All 2009 to 2012 jetta Sport Wagen TDI's in here, also... evidently NHTSA forgot to ask about that model also. They couldn't find a cause for the runaways either.... But that doesn't mean it didn't happen.693Views0likes0CommentsRe: Ford's answers to the NHTSA 6.7 Investigation
The reason the auto business does well is the marketing folks engage the emotions and imagination of the people that pay a ton of money for them, investing not just their money, but their egos in a heap of iron that will, in due course, get old, ratty, unreliable, and need to be replaced for a new improved ego booster! Where egos and emotions don't have as much involvement, like in the purchase of commodities like crude oil, quite different considerations apply. Some of the equipment I work with are so old and decrepit that it is found in antique shops, but by gosh, it still does the job and does it cheap and better than anything else lying around. The interesting story for the CP 4 is a group of immensely self confident and capable engineers, who thought they had the world at their fingertips after their most feared competitor threw in the towel (Siemens), and left the field all to themselves, are now finding that their simpler, cheaper design that produced higher pressures are in an engineering sense, brittle.516Views0likes0CommentsRe: Ford's answers to the NHTSA 6.7 Investigation

Good bye Ford thread at TDS Regards If the drama is left out of the discussion, my bet is it will stick around!

A post over at TDI pointed out this factoid: The brand new 2013 Porsche Cayenne Diesel (with CP4)... Cannot do stop-start (to save fuel).. because... Porsche wrote: “It’s a matter of lubricating the high-pressure fuel pumps,” he adds. “They’re delicate.” Thomas Herold, manager of ?Special Operations R&D http://www.caranddriver.com/reviews/2013-porsche-cayenne-diesel-first-drive-review Nice to know the dainty and delicate HPFPs used in the Porsche diesel.516Views0likes0CommentsRe: Ford's answers to the NHTSA 6.7 Investigation
Lets think chemistry for a bit... I am not a chemist, but here is what comes to mind: 2 Fe2O3 + 3 C ? 4 Fe + 3 CO2 exothermic... Or: 3 Fe2O3 + H2 ? 2 Fe3O4 + H2O Fe3O4 is an abrasive. Mohs Hardness @20°C 5.5 to 6.5 Hmmmm... Slice right through aluminum at Moh 2.5-3 at 20C374Views0likes0CommentsRe: Ford's answers to the NHTSA 6.7 Investigation
Water was not a problem until we saw the higher pressures. All of a sudden, we got water making its way into the system, forming rust particle that are then all subject to 2,000 bar, possibly making the mixture break down again and become reactive. It may not be water per se that is the problem, but the reactive byproducts, or in the case of the photo on dieselsite's thread, metabolites from biofuel that have degraded. We are really heading into unknown territory with the high pressures and biofuels all at once.328Views0likes0Comments
