TLicense Posted April 14, 2005 Share Posted April 14, 2005 Does anyone know about these W configuration engines? Do they have two crankshafts? If so how do they drive an output shaft? If they have only 1 crankshaft, how can you have a W8? Two banks of three and one bank of two? Quote Link to comment Share on other sites More sharing options...
Digsy Posted April 14, 2005 Share Posted April 14, 2005 There are two kinds of "W" engines. True "W" engines (also called "broad arrows" by the old skool) have three individual banks of cylinders, all sharing a common crankshaft (three connecting rods per crank pin). Sometimes the outer two connecting rods are hinged off the centre rod rather, than the crankpin itself. The more recent type of supposed W engines by VAG are actually two VR engines (which have a V angle of only 15 degrees or so and so are essentially inline) on a common crankshaft. VAG describe these as W engines because in German, "W" translates as "dopple V" (two V's). The VAG W8 is actually two VR4s strapped together.

heckler Posted April 14, 2005 Share Posted April 14, 2005 Right - the W8 is formed via two V-4s set side by side, with each V-4's cylinders set apart at a super steep 15 degrees, and the opposition of the two banks of V-4s set at a very flat 72 degrees - All sharing a common crankshaft. Theres also W16 Damn beat be by a minute... Quote Link to comment Share on other sites More sharing options...
Digsy Posted April 14, 2005 Share Posted April 14, 2005 I saw the W16 cylinder block when the first ones had just been cast. Mental! Quote Link to comment Share on other sites More sharing options...

TLicense Posted April 14, 2005 Author Share Posted April 14, 2005 So the VW engines are two V6's bolted together with two crankshafts. So they then have some kind of gearing that bring both cranks to a single ouput shaft? Would one V6 run in reverse to the other, or would there be a reverser gear on one V6's?

Digsy Posted April 14, 2005 Share Posted April 14, 2005 No, the VAG engines are just two VR engines sharing a single common crank. VR engines aren't really "V" engines at all. They are more like inline engines. Quote Link to comment Share on other sites More sharing options...
TLicense Posted April 14, 2005 Author Share Posted April 14, 2005 So the W8 would be 4 banks of 2 on a common crankshaft? Quote Link to comment Share on other sites More sharing options...
heckler Posted April 14, 2005 Share Posted April 14, 2005 2 V4's side by side, on the same crankshaft Quote Link to comment Share on other sites More sharing options...
