Fuelling a Common Rail Diesel

So, does anyone know if it is possible to run such an engine using uk domestic heating oil, without needing any modifications or causing other engine problems?

Peugeot 908

I think the Peugeot 908 LMP1 is something worth noting in this article. Unfortunately I don't QUITE have all the details on it and even then I'm not certain how much of it would be suitable to insert in this article. What does everyone else here think?

TDI and CDI

Dear Author,

Volkwagen TDI is not a common rail diesel. Volkwswagen will probably be starting to build common rail diesel engines from 2007. Source: volkswagen Holland. Regards, Elias

And that's what the article says, Elias...212.181.109.66 (talk) 09:54, 27 May 2008 (UTC)[reply]

How about Mercedes' CDI? They use it in many of their diesel cars.

DCI is already inthe article. See DaimlerChrysler.

Fuel rail

What is a fuel rail ?. --Mac 11:08, 28 June 2006 (UTC)[reply]

Main pipe carrying fuel.

And I believe the common rail was designed long before 1960 as there were Doxford engines were operating with common rail.

Common Rail vs. Unit Injectors

The first part of this article does not describe a common rail system as the term is used in the engine industry, but a unit injector system. A common rail system is an injection system where the fuel rail is held at injection pressure (1000 bar or higher) and the injectors do not perform any internal pressurization. A unit injector system does have a "fuel rail" but it is merely the passage that carries low pressure fuel to the injectors to be pressurized there. Calling this a common rail system to an engine designer will only lead to strange looks.

I don't know - probably no stranger than describing a gasoline direct injection (GDI) engine as running petrol...Jmdeur (talk) 17:57, 8 July 2009 (UTC)[reply]

leaky pump on the common rail

"""They were cam driven and injection pressure was proportional to engine speed. This typically meant that the highest injection pressure could only be achieved at the highest engine speed and the maximum achievable injection pressure decreased as engine speed decreased. This relationship is true with all pumps, even those used on common rail systems; with the unit or distributor systems, however, the injection pressure is tied to the instantaneous pressure of a single pumping event with no accumulator and thus the relationship is more prominent and troublesome."""

maybe it has a leaky pump on the common rail

Article issues

Two issues I noticed with this article.

1. The article describes Fiat's selling of the technology as a tactical error before claiming Fiat "had no choice" in the matter due to its financial situation. How is it a "tactical" error if it "had" to do it? Tactics would suggest Fiat had some choice in the matter and made a mistake.

2. The article claims the technology was invented in the 1960s, but then describes a number of implementations of the technology dating to the early 1900s. One or other is false, either what was developed in the 1960s was merely an improved, modern, version of the technology, or else the earlier implementations weren't common rail systems.

I don't know enough about the subject to answer those questions and would have to delete the claims (which would be a fair chunk of the article) if I made the edits myself, therefore I think it best to comment here. --208.54.94.99 (talk) 14:07, 15 June 2010 (UTC)[reply]
