A clip is a device used to load a magazine...A bullet is one component of ammunition...Ben

 

Actually, it technically depends on whether or not the damper/balancer is, in fact, helping to balance the engine. On some externally balanced engines (Cast Crank Mopar 360s come to mind), this device actually performs some balancing (note the offset when viewed from behind).

But on a typical internally balanced engine, this device does NOT balance anything. You are correct that it is there because of crankshaft twisting, but this is to DAMPEN the vibrations, not "balance" them. The only way to "balance" these vibrations would be to have identical harmonics induced that were 180° out of phase and create destructive interference between the two waves.

This is why "balance shafts" are used on some VEE configuration engines. Because a vee is inherently out of balance, the balance shaft is the only way to counteract this effect by doing just as I described above- generating a force equal and opposite to cancel out the primary force.

That said, there's a reason why there are trade names out there like "Fluidampr" (sic) not, "fluidbalancer".

Submitted for your consideration.

How about people using prolly when they mean probably. I have wondered if that is the way they say it when they talk.

Going by your first post in this thread, wouldn't that be "damp" and not "dampen?"

 

Justin,

Well, actually, 60 degree V-8s (such as the Yamaha-built engine in the last Taurus SHOs) and 90 degree V-6s (all of the V-6s made by lobbing off 2 cylinders) that use split crankpins for an even firing order are inherently unbalanced and need balance shafts. 90 degree V-8s and 60 degree V-6s are fine.

Yall have WAY too much time on yer hands......

 

Then theres this one...

Pound feet of torque or foot pounds of torque.

I hear this stated in both ways often.

Which one is it?

just like guage and gage and gauge

Notice on the Rams its gage?

Then theres the southern folks bellering HEY?!

and us Canucks saying EH!?

Thats aight. Weez yall know wut it means. ah

LOL

 

While were on the subject of meaning WHAT does "LOL" mean I've seen it in a few post and I can't figure it out.

 

What about saying O for 0 (Zero). It's a number not a letter.

 

Laugh Out Loud

 

Thanks

 

Your Very welcome hope it didnt put a Damper on your Surfing.

 

Me?? No. I do know the difference, but I don't get "uppity" about it. I'm not usually an "uppity" kind of guy.

But still, doesn't Ford own Cummins? I thought I read it here:

Can I use Motor Oil in my engine???

 

Hehe... This is getting better with each post!

Thanks for the tech info Rusty. I was talking about the VEE engines being out of balance in the sense of forces acting in different directions, not just firing order dictated by vee angles. I've read that there are certain "ideal" vee angles for a given number of cylinders- 90° for 8 cyl, 60° for 6 cylinders. The idea is basically that # of cylinders times vee angle works out to 360° or a multiple of 360°.

But even a vee engine with the bobweights perfectly matched isn't perfectly balanced. With an inline engine or a boxer configuration, there's a yin for every yang, a zig for every zag. This is what I mean by "balanced".

A vee can't have this because the vee angle means that the forces are acting in different planes, and therefore, cannot cancel each other out.


If I'm mistaken, please educate me-- this is the kind of stuff I LOVE to learn about.
