Talk:V6 engine

It's much better now. But I feel skeptical about all the text related to the VW VR engines (in this article and other). IMO VW makes a good marketing job. The VR engine don't have all the pros of a V and a Straight engine, they have all the cons, but they are very compact. Making such an engine reliable requires superior design technology. Once again VW didn't pionnered this engine the first V6 on the Lancia Lambda was a narrow angle, and the front-wheel drive Lancia Fulvia that surprised everyone in rally racing in the late-60's/early-70's had a narrow-angle V4 that allowed an extroardinary good mass balance for a front-wheel drive car.

Yes: needs a more NPOV. Right now it smacks of a PR job. Tannin 15:08, 31 Aug 2003 (UTC)

Maybe the VR series needs its own seperate page where all this can be laid out without swamping THIS page with it. Cut down the mention of it here. (or is there already an article on the things?) --Morven 22:57, 31 Aug 2003 (UTC)

I think we shoud keep someting on narrow-angle V6s and create a VR engine article. In any case this should be turned to NPOV. Ericd 23:02, 31 Aug 2003 (UTC)

I made some changes. Does that sound better? In addition, I think this page doesn't really emphasise just how popular the V6 has become in recent years. Certainly in the USA where I now live, it seems like almost EVERYTHING now has V6 power (except for the truly large stuff that has V8s). I'm thinking of wording. How popular are V6s in Europe right now? --Morven 23:17, 31 Aug 2003 (UTC)

This is much better but in all narrow-angle V engines "both banks share the same cylinder head" (I'm not absolutely sure about the narrow angle Cadillac V16).

European cars are smaller, the straight-4s are more common. Except BMW the V6 has totally replaced the straight-6. Opel gave-up first and more recently Mercedes-Benz.

Have a look on the straight-6 article.

Hi Morwen I have no time to expand it now but the article lacks a lot about the F1 1,5 L turbo V6s my develloppement aboutr the Renault engine was a step in that direction... Ericd 23:59, 16 Dec 2003 (UTC)

Ah, the Renault turbo F1 engine was developed from that? I'll see if I can find any material ...

I have a lot of references but not much time for now...

Odd-fire

I've just removed the following text:

When two cylinders are "removed" for a V6 variant, the firing order becomes uneven. One 90° ignition is removed, so the engine fires at 90°, 90°, 90°, and skips one 90°. This leads to a rough idle and increased stress on the engine mounts and chassis.

As far as I know, V6 engines have never been built this way. Odd-fire engines come from shared-crankpin V8 designs that have crank journals arranged at 120° between lobes, not 90°. Instead of a 90-90-180-90-90-180 pattern, odd-fire V6s fire in 90-150-90-150-90-150 pattern. --Milkmandan 03:27, 2005 Jan 29 (UTC)
