all four stroke engines
four strok engines are like a scale down version of a car engine. They work the same way. unlike 2 stroke which can work any way E.G: upside down etc. 4 stroke engines need to positioned the right way so they can have a constant flow of oil. does this help?
Because different engines have different advantages. Steam engines can be run from anything that burns, but are big and heavy. 2-stroke (gasoline) engines has great power-to-weight ratio, but tend to use a lot of fuel and create a lot of emissions. 4-stroke Diesel engines tend to run rougher and don't rev as high as gasoline engines but are more fuel efficient and often have more torque.
Yes, I some 2 stroke engines for boats have it and KTM is developing one for dirtbikes.
Because a piston travels up and down the bore 2 or 4 times a cycle.
Bore x stroke
generally , two strokes are smaller capacity , shorter stroke, higher revs. for given engine capacity , long stroke /small bore = high torque / low revs short stroke/big bore = low torque / high revs
The bore and stroke is different, But if you set the 2 side by side they will look the same other then some 400 engines have an extra freeze out plug in the side of the block that the 350 don't have. 350 bore and stroke is 4.000 bore,stroke is 3.480 400 bore is 4.125 and stroke is 3.750
The volumetric efficiency of an engine ( It's ability to breathe ) can be found by finding it's C.I.D. the mathematical formula for Cubic inch displacement is "Bore x Bore x Stroke x .7854 x The # of cylinders".
Bore = 4.00 inches Stroke = 3.48 inches Measure cylinder bore with heads off, measure crank main center-line to rod main center-line then multiply by 2 to get stroke. Stock Chevy 350 is as above.
BORE is 3.740 and the stroke is 3.480
Bore 4.250" Stroke 4.00"
No. The bore, and stroke determine the cid. And they are different on these two motors. The 454, has a longer stroke.
4 inch bore, 3.5 inch stroke.
The bore would be 4.310" and the stroke is 4.00"
4.312 bore x 3.50 stroke.
4.00 bore 3.48 stroke
