Bore = the (internal) diameter of the cylnder hole in the engine block.
Stroke = the distance the piston travels up (or down) the bore during its' cycle.
If you multiply the bore dimension by the stroke dimension you will get the volumetric displacement of that cylinder.
thus,
Vd = (3.1416/4) (dia.) squared x Stroke

What does it mean by define an engine by its Bore X stroke?
bore is the diameter of the piston and stroke is the length the piston moves in the cylinder.for example if bore x stroke is 1x3 then 1 is the diameter of the piston and 3 is the length of the cylinder.if bore is greater than stroke then it is a short stroke engine.
What is the bore and stroke of a Chevy 409?
4.312 bore x 3.50 stroke.
What is the bore of a Ford 4.9L?
Bore x stroke is 4 x 3.96
How do you calculate the engine size on your car?
.7853x bore x bore x stroke x #of clyinders
What is the cylinder bore on a 327 small block?
4inch bore 3.25 stroke formula bore x bore times stroke times .7854= cid
What do you get when you have a bore and stroke of 4.25'' x 4.00''?
Take your bore squared (multiplied by itself) times your stroke times 0.7854 times the number of cylinders in your engine to arrive at your cubic inches (cid). Here is that formula simplified: (bore) x (bore) x (stroke) x 0.7854 x (# of cylinders) = cubic inch displacement.
What are they measuring when they say 350 ci?
The bore & stroke of each cylinder. bore X bore X 0.7854 X stroke X numbers of cylinders = example 4.001 X 4.001 X 0.7854 X 3.480 X 8 = 350 cubic inches.
What is Short stroke and long stroke engine?
It refers to the throws of the crankshaft/distance the piston moves. It usually is compared to the bore of the engine. An example a 302 4"bore x 3"stroke is a short stroke motor, by comparison a 5.4L ford v8 3.552" bore x 4.165" stroke.
How do you measure car engines?
Bore x stroke
How do you figure out cc's of a motor?
bore X bore X stroke X .7854 = displacment 47mm bore with a 49.5 stroke 47 x 47 x 49.5 x .7854 = 85.879 86cc motor bore X bore X stroke X .7854 displacment 47mm bore with a 49.5mm stroke 47 x 47 x 49.5 x .7854 85.879 86cc motor Wat??? 47 x 47 x 49.5 x .7854 85879.9557. How is that an 86cc motor? How about 47 x 47 x 49.5 x .0007854? 85.8799557 or 4.7cm x 4.7cm x 4.95cm x .7854 85.8799557 Do your math before you post wrong answers.
How engine capacity is worked out 4 cylinder engine?
I assume you mean engine displacement? To calculate engine displacement, use this formula: Bore x bore x stroke x .7854 x number of cylinders.
Is a Oldsmobile 455 the same as a Pontiac?
No, they are not the same engine. The Oldsmobile 455 had a bore and stroke of: 4.126 X 4.25 The Pontiac 455 had a bore and stroke of: 4.152 X 4.21
