Correct me if I'm wrong, but the V10 is a 90 degree engine. If that's true then the V10 would not be naturally balanced unless it was a 72 degree engine. So if its 90 degrees, then what has Ford done to make it run so smooth? This is something me and my uncle were discussing. If anyone knows that would be great.

 

Ford does have a balance shaft in one of the heads.

I believe the Dodge V-10 is a balanced design.For what it's worth,it sounds about like a 6 cylinder though.I believe this is the reason.

In my opinion the Ford V-10 sounds way better.Music to my ears.

I'm sure someone has more details concerning Ford's V-10 design.

 

Now, I'm not sure why I'm thinking this but I always thought that a 90° engine had perfect primary balance.

Anywho...the V10 is indeed 90°.

 

This is what I understand about it. For the same cylinder to go from its powerstroke to the next powerstroke requires 2 complete revolutions of the crankshaft, which equals 720 degrees. On a V8, you have 8 cylinders, ofcourse. If you divide 720 by 8, you get 90, which is the degree of the V8 block. So that means on a V8 one cylinder must fire every 90 degrees of crankshaft rotation to keep the engine balanced. So here's how it goes: one cylinder fires its powerstroke, then the other 7 will fire every 90 degrees of crankshaft rotation, when all the other 7 are done, then you're back to the first one, which is guess what-720 degrees later. So on a V10, every cylinder fires its powerstroke every 72 degrees of crankshaft rotation, because 720 degrees divided by 10 is 72 degrees. And to keep the engine balanced, you should make the "V" the same degrees as the amount of degrees between cylinder firings.

All this may sound confusing, but I'm pretty sure I'm right about it. Anyway, since Ford's V10 is 90 degrees, then they must have a different way of balancing it.

 

Hey 4x4x4x4, I forgot to ask, How would a balance shaft in the cylinder heads work??

 

So, does anyone have anymore input on this??

 

I wish I had more to add.
I don't have an engine manual to study this engine (yet) and don't want to speculate for fear of giving bogus info.If I'm not mistaken, there is a balance shaft in one of the heads and is driven by the same system that drives the camshaft.

Hopefully someone much more informed will comment.

 

Yeah but, how would a shaft in the one of the heads keep the engine balanced? Man I wish we could get a Ford engineer on here to answer all of our questions.

 

Whew reading and trying to visualize this kind of gave me a headache but it sounds correct. I know a lot of motors have balance shafts but i thought they were in the crankcase. I'm confused about the block angle the V. What about V6 motors? I think that Buick used to make odd-fire and then even-fire V6s(I could be wrong about that) and i guess they were 90 degree blocks. Abiut the buick even-fire... it seems like i have read many years ago that it was not inherently balanced but with crankshaft counterweights the engineers had limited the unbalance to a purely horizontal plane ie a slight rocking from side to side at idle. I guess this means no blance shaft was used.
But i can't see how the block angle would have changed the balance.
Then again no one is paying me as an engineer
I am very curious for details as to how Dodge designed their V10 .

 

You're right about most balance shafts being in the block. However, it doesn't really matter where they are placed, so Ford put it in the driver's side head. As for the specifics of exactly how it "works", I'll leave that to the more informed.

 

OK, I don't know if this is true or not but I heard that the Dodge V10 fires 2 plugs at a time and has no balance shaft. Ford only fires 1 at a time making the ignition system very complicated. That's the reason some V10 chips cost more than the V8 versions.

 

hey fellas, i am gonna throw a wrench in ye'alls gears.

I always understood that the 'degree' was the actual angle of the V. NOT the firing impulses. I guess this would easy enough to find out if we knew which degree VW's narrow angle VR6 is eh ? I'll check it out.

I'm lost- what's the wrench in the gears?

 

Yep, here it is, off the website supplied above re: engines,

An engine is classified as a V-type if there are two banks of cylinders attached to a single crankshaft. The cylinders are usually positioned at either 90 or 60 degree angles from each other.
