When an engine has a cylinder bore that is larger than its stroke what is this called?

Oversquare


What is over square Engine?

I'm not a mechanic / technician but as far as I know that is where the engine cylinder bore is larger than the 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 Chevy 402?

The 402-cubic-inch V8 is nothing more than a 396-cubic-inch bored out by 0.030. the 396 had a bore of 4.094 in and stroke of 3.76 in. So the 402 had a bore of 4.124 in and stoke of 3.76 in.


What is the difference between a Pontiac 400 and a Pontiac 455?

The Pontiac 400 has a bore of 4.12 and a stroke of 3.75. The Pontiac 455 has a bore of 4.15 and a stroke of 4.21. The 455 cylinder heads will have larger combustion chambers than the same year 400 heads to achieve comperable compression ratios on the larger engine. The blocks are physically the same size, but 455 has larger main bearings than the 400. 455=3.25 400=3.00, so crankshafts will not interchange. Cams,heads,intakes,exhaust,connecting rods,push rods,rocker arms...etc will all interchange.


What is bore slugging?

Bore slugging is done by taking a lead cylinder(slightly larger in diameter than bore) and pounding it through the bore. Once it's through, you mic it with a caliper. This gives the bore's exact diameter.


Is a 8 gauge more than a 12 shotgun?

Yes, it is larger, the smaller the gauge the larger the bore i.e. 3 gauge is larger in diameter than a 8 gauge or a 12 gauge.


Bore and stroke of stock 350 Chevy motor?

A 350 Cubic inch Chevrolet engine has a 4.00 inch bore with a 3.48 inch stroke to produce 349.67 cubic inches of displacement that is rounded up to 350 cubic inches.I know it is splitting hairs, but the displacement is slightly more than (due to rounding errors): 4.00 (bore) * 3.48 (stroke) * 3.14159 (pi) * 8 (cylinders) = 349.84 This knowledge might be useful for a bar-bet at the local watering hole.


Is the piston on a 4 stroke bigger than stroke 2?

Neither a four stroke nor a two stroke have a bigger piston. It all depends on the size of the engine and how it is built. A 250 four stroke will have the same sized piston that a 250 two stroke would if the bore size is the same. Cc is calculated by bore x stroke (how far up and down the piston moves) so if a 250 four stroke has a stroke of 3.00 inches and a 250 2 stroke has a stroke of 3.00 the piston will be the same size. The only difference between a 2 stroke and four stroke is how the engine works. A 2 stroke has reed valves and it makes power every time the piston goes up but a four stroke it makes power every 4 times the piston goes up.


Is stroke volume usually larger than cardiac output?

No, cardiac output is the product of stroke volume and heart rate. Stroke volume refers to the amount of blood pumped by the heart in one beat, while cardiac output is the total amount of blood pumped by the heart in one minute. Typically, cardiac output is larger than stroke volume due to the inclusion of heart rate in the calculation.


What is the specifications for a 3c-t Toyota diesel engine?

Although having a larger displacement than the 2C-T, the 3C-T was more economical and powerful at 69 kW. The displacement is 2.2 L (2184 cc), the cylinder bore is 86.0 mm, the piston stroke is 94.0 mm and the Valvetrain is SOHC.


Geometry of a paintball?

Paintballs are a sphere, and average about .685 caliber, but can be manufactured to .02 larger or smaller than that for different bore matching practices.
