In a 2 stroke, every second stroke of the engine is a power stroke. In a 4 stroke, every 4th stroke of the engine is a power stroke. Knowing this, a 2 stroke has double the power as a 4, in the same cc

Why do most very large engines operate on two stroke cycle?
very large is the keyword here. for a very large engines that runs large machines, we need high power engines. two-strike cycle engines produce more power than 4-stroke cycle engines. that's why they are used. as they produce more pollution than 4-strokes, they must be limited to small spaced engines machines or large machines that required very high power.
Which supplies more power a 4 stroke engine or 2 stroke engine?
2-stroke engines produce much more power than 4-stroke.
Why do most very small engines operate on a two-stroke cycle?
two-stroke engines can produce more power than four-stroke engines that have the same size. they can occupy small spaces and produce the desired power. they are on the other hand produce more pollution than 4-stroke engines. that's why they are limited or suitable for small engine spaced machines
Why do most very small engines operate on 2 stroke?
Most small engines are two stroke because you can get more power from a smaller engine with two stroke rather than a four stroke engine. It takes less to cool and to operate the engine.
2 stroke vs 4 stroke?
On a 2 stroke engine, each cylinder fires every time the piston comes up. On a 4 stroke engine, the cylinder only fires every OTHER time the piston comes up. 4 stroke engines have 4 strokes: Intake, compression, power, and exhaust. 2 stroke engines complete these cycles in only two strokes of the piston by use of ports in the cylinder walls. 2 stroke engines usually produce more power for a given weight/size. But, in gasoline engines, 2 stroke engines are typically less efficient (use more gas) and have much higher pollution levels (note: some newer "direct injection" 2 stroke engines do much better on pollution levels than the typical 2 stroke)

Who is more cheaper two stroke or four stroke engines?
2-strokes are generally cheaper as they have fewer moving parts and can be made smaller for the same power output.
What does stroke mean for quad bikes?
Stroke refers to how the pistons move in the cylinder(s).The basic meaning is the length of the piston travel. Short stroke engines can turn over faster, but long stroke engines tend to have more pulling power.Stroke can also be used as 2-stroke and 4-stroke, which refers to the different work phases of the engine. 2-strokes give more power for their size, but they pollute more and often use more fuel. 4-stroke can be cleaner, but bigger, heavier, and have more parts.
Four-stroke cycle engines are more fuel efficient than two-stroke engines?
Unless we are talking about big diesels - Yes.
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.
Why four stroke engines are not used for marine propulsion?
They are - most inboard engines are 4-stroke. But as with land vehicles, you can get a smaller engine with 2-stroke (or more horsepower with a smaller engine) so the small engines like some outboards tend to be 2-stroke.
What kind of engines are in a plane?
jet engines, turbojet engines, turbo-prop engines, four-stroke piston driven engines... Can you be more specific?
