Answer 2

Less mass, and less moving parts equals less friction, therefore more power.

When the piston goes up, it draws fuel and air into the space under the piston. As the piston goes down, it squeezes this mixture through an opening in the side of the cylinder so that it is now above the piston. The piston rises again, compressing the air and fuel inside the cylinder (and sucking the next charge underneath the piston at the same time.) Near the top, the fuel ignites, and the exhaust gas exits the pipe while the piston starts going down again - while also squeezing the next charge of air and fuel into the cylinder. Since there are no regular valves or valve springs (the piston acts as a rudimentary valve as it passes the intake and exhaust ports), there is less internal friction, and therefore more power available to the crankshaft.

This system makes a lot of power, since there is a power stroke every revolution, rather than every second revolution like a 4-stroke engine. The down side is that they tend to make their best power at very high RPM (meaning high wear on internal parts), and they usually don't burn the fuel efficiently (meaning worse emissions and comparatively high fuel consumption.)

mdcbert has included links that show this sequence very well - I recommend it.

Good luck!

Answer 3

Both a 2 and 4 cycle engine do the same thing, except they do it differently. There are four things that happen in both engines.

1 - Intake (of air/fuel for compression)
2 - Compression (the piston compresses the air /fuel mixture)
3 - Power (ignition of the air/fuel mixture, driving the piston downward)
4 - Exhaust (the valves open and the burned gases are exhausted)

The 2 cycle doe this in two strokes of the piston and the 4 cycle strokes of the pistion. When I say strokes it means movement of the piston in an upward or downward motion . . .

Answer 4

the adaptation between the two kinds of engines is interior the cycles. The 4 stroke engine has 4 ranges induction, compression, capacity and exhaust. the two-stroke engine has merely compression and capacity strokes. a million) for a similar engine velocity, a 2-stroke engine supplies two times the form of capacity strokes. i.e. is greater effective 2) The absence of a exhaust stroke potential, the exhaust valves open merely till now the capacity stroke is achieved. The potential some unburnt gasoline is likewise expelled. This makes it much less gasoline-effective. 3) for a similar reason, that's greater polluting than an equivalent 4-stroke engine. this implies, you won't be legally waiting to in high-quality condition one on your vehicle. there is different reaons yet those are the greater compelling motives. For mroe understand-how, you may look up on how those 2 kinds of engines artwork. A start up may be the URL I actual have given as my source.

Answer 5

Less moving mass and the exhaust has a lot to do with it.....two cycle engines combine compression and intake cycles and power and exhaust cycles and REV much higher than four strokes...hope this helps

Answer 6

Because it fires on every second revolution instead of on every 4th revolution on the 4 cycle engine.

Answer 7

By burning fuel in an enclosed cylinder.

Answer 8

internal combustion
