Talk:V8 engine

Missfiring?

I have a question why have the most old american engines a missfiring order,like the 427 Ac cobra engine?

V-angles

There's a reference to an engine (Lancia V4) as being "almost completely square". It would be useful if that term were defined; i.e. either with parenthetical note "(i.e. equal bore and stroke dimensions)" or footnote to avoid confusion by people unfamiliar with the term.

I amended it to indicate that the Lancia V4 was "square" in length and width, not bore and stroke. The early ones were actually rather long-stroke, narrow-bore engines.RockyMtnGuy (talk) 05:29, 10 August 2009 (UTC)

Conversion Units

I can't recall a time since the early to mid-80's in which american V8's were still being machined and/or marketed in cubic inches. Nowadays, all V8 engines made by american automakers are done metric and this should be reflected in the article. 24.138.19.131 (talk) 20:47, 6 January 2010 (UTC)

You can refer to the Wikipedia:WikiProject Automobiles/Conventions#Conventions for the standards to be used in articles. In particular: "We express the metric displacement before the cubic inch displacement, except when discussing engines originally engineered, designated, and marketed in cubic inches, such as pre-1980s American and pre-1974 Australian engines. For engines originally engineered and designated in cubic inches but later given metric designations, use {{Auto Lrev}}." I hope this helps! CZmarlin (talk) 04:15, 7 January 2010 (UTC

122.151.109.74 (talk) 16:27, 21 January 2011 (UTC)Diesel locomotives in 90% of U.S. locomotives and derivitives made under license are of a Vee configuration. Often modular in design; viz V6, V8, V12, V16 and V20. Both GM EMD and Alco use this approach. The inline 6 whilst common in trucks is not as common in diesel locomotives. The same reason the Vee configuration engine is popular in cars (compact for power output) also applies to locomotives.

Angles

Modifed the lead picture caption from , although modern automotive versions use a 90-degree block angle. Oversimplified and misleading at least and arguably inaccurate... Ferrari and GM have both used some really odd angles, and several makers have used both 60 degree and 180 degree V8s. Andrewa (talk) 21:05, 30 December 2011 (UTC)

Railroad usage

from the article:

"...railroad locomotives tend to use the straight-6 configuration..."

With the exception of small industrial or switching (shunting) units, locomotives typically are powered by Vee designs, generally in 8, 12, 16 or (more rarely) 20 cylinders. Some early EMD switchers were powered by a V-6 design. ALCO did use some inline-sixes, but these units are mostly of historical interest now.

I've removed it. Although straight-6 and V8 locomotive engines aren't unknown, they're both too unusual to be mentioned in passing like this. Even for small (200 bhp) engines, these layouts are rare in locomotive use. Andy Dingley (talk) 10:03, 25 February 2012 (UTC)

Country Engine Sounds

Wich other engines from other countrys sounds like the american v8? Saludacymbals (talk) 8 April 2012

The American V8 has a distinctive sound because of its unbalanced firing order (LRLLRLRR) emphasises first one bank and then the other, giving a burble sound. This is only true of the V8's with cross plane cranks but most American V8's are of this type because they make less second order vibrations, giving more thump-thump, less buzz. Race V8's often use flat plane cranks which sound and feel more like two 4-cylinder engines but make more power due to less first order vibrations (which kill bearings), giving less thump-thump and more buzz. Australian (eg Holden 308) and Japanese passenger V8's (eg Lexus 1UZ-FE) sound like American V8's for the same reason.  Stepho  talk  20:30, 7 April 2012 (UTC)
