On what basis are engines classified as small bore or large bore?
Engines are classified as small bore or large bore based on the diameter of their cylinders. Typically, a small bore engine has a cylinder diameter of less than 100 mm, while a large bore engine has a diameter greater than 100 mm. This classification affects the engine's performance characteristics, including power output, fuel efficiency, and torque characteristics, with large bore engines often providing higher power and torque at lower RPMs.
What is the application of Otto cycle in industry?
all four stroke engines
Why does two stroke engine pollute air more than a four stroke engine?
Two-stroke engines generally pollute the air more than four-stroke engines due to their design and operation. In a two-stroke engine, the combustion cycle is completed in just two strokes of the piston, which often leads to incomplete combustion and unburned fuel escaping during the exhaust phase. Additionally, two-stroke engines typically mix oil with fuel for lubrication, resulting in higher emissions of hydrocarbons and particulate matter. In contrast, four-stroke engines have a more efficient combustion process and separate lubrication systems, leading to lower emissions.
How four-stroke engines work?
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?
Why do you have different types of engines?
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.
How do you measure car engines?
Bore x stroke
Why two stroke engines are hi-speed engines and four stroke engines are hi-torque engines?
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
What is the difference between a Chevy 400 and a Chevy 350?
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
Why is volumetric efficiency measured only for 4 stroke engines and not for 2 stroke engines?
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".
How do you determine the bore and stroke of stock 350 motor?
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.
What is bore and stroke of Chevy 454?
Bore 4.250" Stroke 4.00"
What is the bore and stroke of a Chevy 305?
BORE is 3.740 and the stroke is 3.480
What is the bore and stroke for a 1986 Chevy 350?
4.00 bore 3.48 stroke
What is bore and stroke 351windsor?
4 inch bore, 3.5 inch stroke.
What is bore and stroke of Chevy 468?
The bore would be 4.310" and the stroke is 4.00"
What is the bore and stroke of a Chevy 409?
4.312 bore x 3.50 stroke.
Is a 454 big block and a 472 big block the same?
No. The bore, and stroke determine the cid. And they are different on these two motors. The 454, has a longer stroke.
