V12 is no where as smooth as a boxer engine because of the "V" configuration 😉

Opposing cylinders are inherently balanced, "V" engines are not 😉

i thought i read in a link i posted in the other thread that ended talking about engines, that a flat 6 and v-12 are the only 2 inherently balanced engines.
 
Incorrect, they cannot be inherently balanced because they are in a "V" configuration, they are smoother than other "V" type engines because of the large amount of firing pulses seen by the crankshaft for every revolution.

Do you know what inherently balanced means ?

yes! no!


Maybe!


well...


i know it has something to do with engine smoothness. i'm guessing it means by design it doesnt cause shear stress on the crankshaft.
 
It means the the reciprocating assembly (the pistons and crank) are in perfect balance because of engine design.

The only type of engines that are like this are boxer and radial engines.

Inline 6s are inherently balanced. V12s are just 2 I6s put together, IIRC.
 
My Camaro V8 is unbalanced... and I like it that way. You're supposed to enjoy the way a powerful engine shakes you around your seat while you idle. Smooth engines are for wussies.

Those are not inherently balanced, they are internally balanced, two completely different things.

Look at this VW Beetle crankshaft, notice there are no counter weights, that because the Beetle engine is a boxer engine (flat four), it has opposing pistons which makes it inherently balanced.

You can balance any engine internally by adding counter weights but it will still exhibit secondary shaking forces no matter what you do to it, the only way to stop these forces is to add balance shafts.

As I stated before, only radial and boxer engines are inherently balanced.

Understand ?

Merry Christmas everyone, got to go 🙂
 
is there a different way to define smoothness other than when you sit in the car and you can feel the engine running?

my dads car runs so smooth, he has occasionally gotten into it running and tried to start it again (starter grinds nicely) and it's a V6.. it's so freakishly smooth you can't even tell it's running... so how could an inline 6 be smoother than that?

this is what i want to know. heh...

don't lie. you just like the vibration of the seat. 😛

I understand what you're saying, but I was just regurgitating what google showed me 😛 😀
