Two strokes have two cycles the piston go through intake/compression and ignition/exhaust where four strokes have four separate piston cycles intake compression ignition and exhaust.

Do you find carburetor in 4 stroke engines or 2 stroke engines?

Both 2-stroke and 4-stroke engines have a carburetor.


What is different between 4 stroke engine and 6 stroke engine?

As per my knowledge, There is no any 6 stroke engine in existance. The engines are catagorised as 2 Stroke and 4 stroke engines. The difference is 1)Suction 2)Compression 3)Ignition and 4) Exhaust (called power cycle) complete in 2 or 4 strokes.


What is the difference between a 2 stroke and a 4 stroke lawn mower engine?

Four-stroke engines have a spout where you add oil to the engine. On two-stroke engines, oil has to be added to the fuel. (Four-stroke and two-stroke are also called four-cycle and two-cycle, respectively).


Is a Suzuki DT115 TCLK a 2 stroke or 4 stroke motor?

DT model engines are 2 stroke


What is the difference between a 4-stroke and a 2-stroke ATV?

A 2 stroke will require oil & gas mix while a 4 stroke will not. 4 stroke engines are usually quieter also. Check out link below. http://www.howstuffworks.com/two-stroke.htm


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 are advantages of two stroke engines over four stroke engines?

There are a couple, less parts for one therefore lighter. Also, 2 stroke engines fire every time the piston comes to the top. Which means every stroke is a power stroke. 4 stroke engines fire every other time.


Does Yamaha 80cc 4 stroke take 2-cycle oil?

No. In this case, stroke and cycle means the same thing. So 2-stroke/2-cycle engines should have 2-stroke/2-cycle oil and 4-stroke/4-cycle engines should have 4-stroke/4-cycle oil.


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.


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)


What is the purpose of the piston ring locating pins?

To keep the rings from rotating on 2 stroke engines. You will not see this on 4 stroke engines.


Engine's compression ratio is greater between 2 stroke and 4 stroke engine?

Typically, a 2-stroke engine has a higher compression ratio compared to a 4-stroke engine. This is because 2-stroke engines can complete a power cycle in just two strokes of the piston, allowing for a more compact design and higher compression. However, the specific compression ratio can vary widely depending on the engine design and application. In general, while 2-stroke engines may have higher ratios, 4-stroke engines tend to be more efficient and produce less emissions.
