Appia Engine Question.

[msteven515]

Is the Appia Lancia's only V4 engine configuration or were V4s used in other Lancias?

Thanks,

The V4 was first used in the Lambda, then successively in the Artena, Augusta, Aprilia, Appia, and finally, the Fulvia.

Here's a Wikipedia link (http://en.wikipedia.org/wiki/Lancia_V4_engine) with more info. (Standard caveat about the potential for inaccuracies in Wikipedia, though.)

as well as the Belna (French Augusta variant), Ardennes (French Aprilia variant), and Ardea.

one could also say that the Flavia and Gamma had a 180 degree V-angle engine ;)

Technically that's completely true--it's not a 'boxer' layout. But it always seems only a half-step away from calling the Beta engine a 'V' with a 0-degree V-angle...

Are the rods twinned on the same journal? AFAIK that's the determining factor between the nomenclature of a HO and a 180 degree V.

Picture below of the Gamma crank. The definitions I have are that a boxer engine has a crank design wereby each pair of pistons hit TDC at the same time and BTC at the same time (i.e. they are on seperate pins at 180^ separation).

A 180^ V engine has pairs of pistons on the same pin so one of a pair will be at TDC when the other is at BDC).

The Gamma looks like the former ?

Agreed, with both your statements. It may be splitting hairs, but the only 180V I can think of off the top of my head is the Testarossa engine?

IIRC, the flat 12 in the Porsche 917 was also a 180-deg V (at least that the first time I recall hearing that term).

Thanks! I have two used V4s in unknown condition that I'm about to post on Ebay for a client.

I just took a quick look on eBay; those are Appia V4s. The Aprilia/Ardea V4 has a single 'camel-like' valve cover, and the Fulvia V4 also has a single valve cover and is canted over at 45 degrees.

But if that's why you wanted to know, why didn't you just post a picture and ask for an ID?

Thanks! I ammended the Ebay listing to reflect Appia only.

No problem; happy to help. But, as I said, you could have saved some trouble if you'd started with the real question.
