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 a two stroke fire every time?
Every two strokes, thus the name. A four stroke takes fires every four strokes.
Why do 2 cycle engines run hotter than 4 cycle?
A two stroke engine fires (an explosion in the motor) twice as often as a four stroke. A stroke is every time the piston in the engine changes direction. (From up to down) A two stroke engine fires every time the piston comes to the top where a four stroke will fire every other time. So if two single cylinder engines are running at 1,000 RPMs a two stroke will fire 1,000 times a four stroke will fire only 500 times. With twice as many explosions it will be hotter.
How do you start a dirt bike when its cold out?
depending on if its a 2 stroke or a 4 stroke with my 2 stroke I turn the choke on and tip it until the carburetor bleeds. and it fires up every time
Why initial pickup is better in two stroke engine as compare to four stroke engine?
The two stroke has more initial pickup because combustion happens every time the piston is at or near the top dead center. In the four stroke, combustion happens every other time the piston is at or near top dead center. <><><><><> Since the combustion cycle occurs every rotation, instead of every other rotation, there is twice as much torque available to the engine output.
How do 2 stroke engines provide more power than a 4 stroke?
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
How could a stroke be a cause of death?
a stroke can cause death, but it will not always kill a person
What happens to the speed using 2 stroke compare to 4 stroke?
two stroke engines have a power stroke every second revolution of the crank shaft. four strokes have a power stroke every fourth revolution of the crank shaft. that is why a 125cc two stroke has about the same power as a 250cc four stroke.
How often do you breathe while doing butterfly stroke in swimming?
Every Three Stroke's.
Why two stroke engine called by this name?
on 2 stroke engines the cylinder fires everytime the piston comes up. on 4 stroke engines the cylinder fires every other time the piston comes up http://videos.howstuffworks.com/user/4729-two-stroke-cycle-engine-video.htm
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.
What type of engine delivers power with every down stroke of the piston?
2-stroke engine
