Displacement

[Cecil14]

Is there a formula for figuring the displacement of a motor? Something involving the bore and stroke maybe?

Thanks,
Anthony

Try this online calculator: http://www.wheelspin.net/calc/calc1.html it saves me from hurting my head trying to remember formulas smile.gif

TAKE 1/2 THE BORE AND X IT BY ITSELF AND TAKE THAT AND X THAT BY 3.14 THEN TAKE THE STROKE AND X THAT BY THE TOTAL THAT YOU GOT FROM THE 3.14 AND THEN X THAT BY THE NUMBER OF CLYs YOU HAVE....GET IT? GOT IT? GOOD!!!! :confused: :D :D

cu.in = 0.7853982 x bore squared x stroke x number of cylinders

Come on college boy, you should have been able to figure that one out! smile.gif Displacement = Volume. So you take the area of the bore times the length of the stroke times the number of cylinders. I'm sure it has already been figured out for you though. I don't know of any engines that have been designed where they didn't bother to calculate the displacement. smile.gif

Gary, your equation needs some work.

Area = pi x r squared
or = pi x (d squared)/4

Then times stroke and number of cylinders.

I prefer to remember Pi to the 5th digit. It's more accurate,

PI=3.14159

PI=3.14159A mathmetician, a physicist and an engineer were all asked to say how they describe 'pi'

The mathmetician said "It's the numerical relationship between the diameter of a circle and it's circumfrence."

The physicst said "It's 3.14159265358979323846433832785."

The engineer said "It's 3, more or less."

And the technician said "pi are round, cornbread are square".

Sigh!!! What ever happend to,: "Well its got a 360 PUNCHED OUT 30 over, 4 BBL and a Wicked Cam" Sounds way cooler and impressed the heck out of the YUPPIES. Not to mention a whole lot easier on the Calculator batteries and my BRAIN!!!!!!!
